Ranking the best Irish sea moss of 2022

Written by John Davis

Last updated: July 2, 2022

Irish sea moss, sometimes known by its scientific name of Chondrus crispus or simply as “sea moss,”  is a species of algae found in the ocean that is often taken as a supplement for improving cardiovascular health, sustaining metabolic function, fighting inflammation, and boosting antioxidant levels.

This algae is rich in iodine, antioxidants, and the gel-based compound carrageenan, which is thought to be responsible for many of its potential health benefits. It’s an increasingly popular ocean-sourced superfood that requires minimal preparation, even when using it in its raw form. 

Looking for the absolute best Irish moss supplements on the market? Our research team has evaluated and ranked the best options available, plus provided an in-depth analysis on the benefits, side effects, and applications of Irish sea moss. 


1. Double Wood Supplements Irish Sea Moss

Double Wood tops our rankings thanks to its simple, focused, and convenient supplement design strategy: This supplement includes wild-harvested Irish sea moss extract, and aside from a cellulose capsule, zero additional ingredients.

For people who don’t want to bother with the extra mess and prep time for powder-form or raw Irish sea moss, this capsule-based supplement is our go-to recommendation. The ease of use and effective dosage makes it our top overall pick. 

2. Red’s Kitchen Sink Sea Moss

Check price at Amazon

Red’s Kitchen Sink makes a wild and sustainably-harvested raw sea moss that’s a favorite among people looking for raw, unprocessed sea moss for blending up into shakes, smoothies, or cleansing drinks.

While you have to soak and blend up the raw sea moss yourself, there’s no better option out there when it comes to getting sea moss in its natural, unprocessed state.

For purists looking to maximize the nutrient content of their Irish sea moss, Red’s Kitchen is the way to go. 

3. Super Organics Irish Moss Powder

Check price at Amazon

Super Organics makes a pure and simple Irish moss supplement with just one ingredient: organically-certified Irish moss powder.

There’s no better option out there when it comes to powder-form Irish moss, and when it comes to convenience it can’t be beat–it’s our favorite when it comes to mixing into protein shakes, smoothies, or meal replacement shakes. 

4. Wixar Wildcrafted Sea Moss Powder

Check price at Amazon

Wixar is a great choice if you are looking for a multi-ingredient algae supplement that’s based around Irish sea moss, since it also includes the popular thyroid and joint health compounds bladderwrack and burdock root.

Though there are better single-ingredient options out there for Irish sea moss, it’s a good option if you want an easy way to combine your Irish sea moss with burdock and bladderwrack. 

5. Power by Naturals Sea Moss Plus

Check price at Amazon

Power by Naturals makes a capsule-based Irish sea moss supplement that combines the antioxidant properties of Irish sea moss with the vitality-boosting properties of bladderwrack and burdock root.

These ingredients are mixed up in a 5:5:4 ratio, so you get a nicely balanced distribution of ingredients, making this our preferred option if you want a capsule-based Irish moss supplement that’s combined with other algae-based remedies. 

6. Maju Superfood Irish Sea Moss

Check price at Amazon

Maju Superfoods makes a multi-ingredient supplement that combines three of the most powerful algae supplements (Irish moss, bladderwrack, and burdock root), plus black pepper extract to boost bioavailability.

The formulation leans more heavily towards Irish sea moss than some of the other multi-ingredient algae supplements, so it’s a better option if Irish moss is your main focus, with burdock and bladderwrack added in for their ancillary benefits.

7. Karibbean Flavours Dried Seamoss

Check price at Amazon

Karibbean Flavours makes a cooking-oriented raw Irish sea moss that’s well-suited for home-made sea moss gel. The primary downside compared to other raw sea moss supplements on our rankings is its smaller size: it’s less well-suited for frequent use, like in cleansing or detox regimens. 

8. True Sea Moss Gel

Check price at Amazon

True Sea Moss is a rarity among Irish sea moss supplements: it’s already in gel form, having been blended, soaked, and sealed in a jar.

While this saves some prep time, it does mean that the sea moss is not quite as fresh as if you’d gotten raw Irish sea moss and prepared it yourself.  

9. Secret Element Organic Sea Moss

Check price at Amazon

Secret Element makes a high-dosage multi-ingredient algae supplement that provides Irish sea moss alongside bladderwrack and burdock root.

Though this supplement is popular, it ended up lower in our rankings because these three ingredients are combined in a “proprietary blend,” making it difficult to determine whether each of these three are being delivered at an effective dosage. 

10. Wixar Naturals Sea Moss Gummies

Check price at Amazon

Wixar Naturals Sea Moss Gummies fill a very specific niche: an Irish sea moss supplement for people who don’t like capsules, and don’t want to bother with powder-form or raw Irish sea moss.

Though these gummies fill this niche well, most people will be better off with a different supplement, since the purity and the dosage necessarily suffers when packaging this supplement in gummy form. 

Category winners

Best Irish sea moss overall: Double Wood Supplements Irish Sea Moss

Double Wood is our overall favorite Irish sea moss supplement because the capsule-based formulation helps make the health benefits of sea moss available to everyone.

Raw and powder-form Irish sea moss is great for people with the time to make specialized shakes and smoothies, but when it comes to ease of use, these ultra-pure capsules can’t be beat. 

Best Irish sea moss for heart health: Red’s Kitchen Sink Sea Moss

Capsules are great for convenience, but for people who want to unlock the full power of Irish sea moss, Red’s Kitchen is the way to go.

You’ll need to do some extra prep work to soak and blend up this raw sea moss, but the result is a sea moss gel that’s packed with carrageenan and other compounds with strong potential for boosting heart health. 

Best Irish sea moss capsules: Double Wood Supplements Irish Sea Moss

For convenience, it’s hard to beat Double Wood Irish Sea Moss. These capsules deliver 600 mg of 10:1 Irish sea moss extract, which helps pack more nutrients into less space.

They’re our recommendation for people who don’t want to bother with shakes and smoothies. 

Best Irish sea moss powder: Super Organics Irish Moss Powder

Super Organics strikes a nice balance between convenience and versatility with this powder-form Irish sea moss: you can blend it up into your favorite smoothie or shake, and you don’t need to bother with soaking and blending it first.

At the same time, you also get full control over the dosage, and to seal the deal, it comes from sustainably-sourced all-natural Irish sea moss. 

Best raw Irish sea moss: Red’s Kitchen Sink Sea Moss

If you’re looking for raw Irish sea moss to prepare at home, Red’s Kitchen is our favorite: it’s a sustainably-harvested and minimally-processed Irish sea moss that comes in a hefty eight ounce bag that makes it great for occasional or regular use. After soaking and blending, it can be easily added to shakes, smoothies, or meal replacement shakes

Best Irish sea moss with bladderwrack: Power by Naturals Sea Moss Plus

Irish sea moss is often combined with bladderwrack, another medicinal algae. For this purpose, Power by Naturals Sea Moss Plus is our recommendation.

It provides Irish sea moss alongside bladderwrack and burdock root in a balanced formulation that doesn’t short-change any of the ingredients, ensuring you get a potent dose of each. 

Who should buy Irish sea moss?

Irish sea moss is a great supplement for people looking for a naturally-sourced superfood that has cardiovascular, inflammation, and hormone regulation benefits. 

Irish sea moss is often used by people looking to supplement their diet with something that can help them lower their cholesterol levels.

Some research suggests that the cholesterol-lowering effects of Irish sea moss are the result of its carrageenan content, which slows or blocks the absorption of lipids in your diet. For this reason, it’s a great option if you are looking for a sea-sourced supplement to improve your heart health. 

The antioxidant properties of Irish sea moss also make it a good candidate for people looking to cut down on systemic inflammation.

Scientific research shows that the carrageenan in Irish sea moss can significantly cut down on biomarkers of inflammation, so it’s a particularly attractive supplement for people dealing with inflammation-based health complaints. Like with its cholesterol-lowering effects, researchers hypothesize that the carrageenan content of Irish sea moss helps protect your body from the infiltration of inflammatory cells. 

Irish sea moss is also rich in iodine, making it a good option for people who want to better regulate their thyroid function through boosting their iodine intake with a natural superfood. Irish sea moss ranks above many popular sources of iodine-rich foods, like fish, shrimp, eggs, beef liver, and chicken. 

How we ranked

To make our rankings of the top Irish sea moss supplements, we first started by collecting a range of Irish sea moss products on the market in all types of formulations: raw sea moss, powdered sea moss, capsule and tablet-based supplements, and gummies.

We considered both pure Irish sea moss supplements and those that combined Irish sea moss alongside other algae-based nutraceuticals, like bladderwrack and burdock root, since combining these ocean-sourced ingredients is a common supplementation strategy. 

After amassing a wide range of products, we started stratifying based on the formulation and the ingredient strategy. Single-ingredient Irish sea moss supplements scored higher, since they necessarily deliver a higher dosage.

Additionally, our top-rated products were those that provide a balance between purity and ease of use. Raw Irish sea moss supplements, like Red’s Kitchen Irish Sea Moss, scored highly in the purity category, and single-ingredient capsules like Double Wood Supplements Irish Sea Moss scored well in terms of both purity and ease of use. 

Since many people soak and blend Irish sea moss to make their own gel-based supplement, we took a close look at raw sea moss supplements. We put a particularly large emphasis on purity and clarity with regard to sourcing, because people who make their own sea moss gel do so to get the maximum amount of vitamins, minerals, and phytonutrients as possible.

The highest-scoring candidates in this category, like Red’s Kitchen and Karibbean Flavours, provided detailed info on the sourcing, purity, and sustainability of their Irish sea moss. Other brands got dropped from the running because they didn’t provide enough details on how and where their Irish sea moss was sourced and harvested from. 

We applied similar rules for powder-based supplements. Pure and sustainably sourced products like Super Organics got ranked highly, while others with unclear sourcing got dropped from our rankings. 

While multi-ingredient supplements that provided Irish sea moss alongside burdock root and bladderwrack didn’t make the top few spots because of their lower dosage, we ensured that those that remained in our top ten were the best-quality options on the market–meaning they sourced their ingredients sustainably and delivered effective dosages of all three of these algae extracts.

Products that hid their content behind a “proprietary blend” of different ingredients were ranked lower, or were eliminated entirely. 

Dosage issues were also the reason why gummy-based Irish sea moss supplements fared poorly in our rankings: while they do fill a niche for people who want a convenient way to take Irish sea moss but don’t want to prepare powder or raw sea moss themselves, the tradeoff in terms of effective dosage is just too high for most–that’s why Wixar Naturals was the only gummy-based supplement to make our rankings (and even then, just barely).

The others got dropped because of their low dosage and lack of benefits compared to other methods of taking Irish sea moss.  

Convenience-based issues are why pre-made gels ended up fairly low on our rankings. While Irish sea moss is great for making your own gel (via soaking and blending raw Irish sea moss), pre-made gels lose the convenience of powders and capsules, but they don’t have the freshness advantage that a home-made Irish sea moss gel would have.

True Sea Moss Gel was the only gel-based Irish sea moss product to remain in our rankings, and it ended up fairly low because of the inconvenience of the glass jar and the lack of freshness compared to raw Irish sea moss that’s gelled at home. 

Lastly, we compiled our final list by aggregating the remaining products in each category, adding points for purity and ease of use. Our final list of the best sea moss supplements on the market had a strong balance of capsule-based, powder-based, and raw Irish sea moss, meaning whatever you’re looking for, you can find what you need.


Irish sea moss has been studied for its ability to reduce cholesterol levels. One of the most widely-used applications for Irish sea moss is heart health: the active compounds in Irish sea moss might help reduce levels of artery-clogging cholesterol. 

According to a study published in 2003 in the Asia Pacific Journal of Clinical Nutrition by researchers in the Philippines, the compound carrageenan, found in Irish sea moss, can lower blood cholesterol when taken for several weeks (1).

The study involved 20 volunteers who took either a carrageenan source to use as part of their regular diet, or who continued their usual food intake.

The groups were then switched, so all subjects tried both the carrageenan diet and the placebo diet. After each intervention the researchers measured the blood cholesterol levels of the study participants.

The results showed that blood cholesterol levels dropped significantly. Total cholesterol dropped, and HDL cholesterol (“good cholesterol”) increased.

A follow-up study published by Russian researchers in 2014 in the journal PharmaNutrition confirmed the blood lipid benefits of sea algae (2). Their study assigned 40 people with high cholesterol either to an experimental group or a control group.

The experimental group received a carrageenan supplement, while the control group received no supplement. After the study’s conclusion, the results showed that the carrageenan supplement group showed significant decreases in their LDL cholesterol, also known as “bad cholesterol” because of its artery-clogging effects. 

The carrageenan in Irish sea moss can reduce systemic inflammation. One additional finding of the Russian study discussed above was a noticeable decrease in several biomarkers of inflammation.

Because of the importance of systemic inflammation in the development of heart disease, the research team also recorded levels of several biomarkers related to inflammation, including leukocytes, fibrogen, and C-reactive protein. Higher levels of all of these biomarkers are associated with greater systemic inflammation in the body.

The same group of high cholesterol patients who experienced decreases in blood cholesterol also experienced decreases in these biomarkers of chronic inflammation, to the tune of eight to 16 percent.

These results indicate that Irish sea moss, with its high content of carrageenan, could serve as a powerful anti-inflammatory, helping with health problems related to high systemic inflammation.

Data from animal studies suggest that Irish sea moss and other sea algaes could improve metabolic health, even if your diet is unhealthy. New research published in 2020 in the journal Marine Drugs used lab rats to test the effects of carrageenan sourced from sea algae on adaptations to an unhealthy diet (3).

Lab rats are often used as a model of metabolic syndrome (the precursor to type 2 diabetes) because they reliably develop metabolic dysfunction when fed a high-carb, high-fat diet. 

This study used just this kind of intervention to induce metabolic syndrome in rats, but with one key difference: half of the rats in the study were given a sea algae supplement high in carrageenans.

The findings of the study indicated that the high fat and high carbohydrate diet was much less damaging to the metabolic function of the rats fed the algae. Citing changes in the gut bacteria of the rats fed the algae supplement, the researchers hypothesized that two mechanisms caused the difference in metabolic function.

First, the researchers suspected that the carrageenans functioned as a prebiotic, supporting the growth of healthy gut bacteria, and second, that the carrageenan blocked the ability of inflammatory cells (generated by the unhealthy diet) to make their way into the organs of the rats.

Of course, while it’s far better to have a healthy diet, these findings suggest that Irish sea moss might be able to ameliorate some of the negative effects of high fat and high carbohydrate diets. 

Irish sea moss is high in the essential nutrient iodine. Iodine is a mineral that contributes to thyroid function, weight regulation, and mood stability.

Among natural foods, algae-based foods are particularly good sources of iodine, and even among sea-sourced algae, Irish sea moss is particularly high in its iodine content. According to one study published in 2020 by a team at the University of La Laguna, raw Irish sea moss contains more iodine per unit mass than many foods rated as high in iodine, including fish, dairy, eggs, and chicken (4).

The study estimated the iodine content of Irish sea moss at about 0.4 milligrams per 100 grams of dry Irish sea moss. For comparison, the upper limit of iodine intake for adults is 1.1 mg per day (chronic intake of iodine above this level can cause health problems). 

The researchers recommended taking iodine content into account when using Irish moss and other seaweeds as a functional food, as too much can actually cause iodine overload.

This isn’t much of a risk when using capsule or gummy-form Irish sea moss, but preparations from raw Irish sea moss can come in much higher dosage. The research team recommended keeping intake of Irish sea moss below about 200 grams per day to keep the total amount of iodine below the recommended upper intake limit.

Exceeding this amount would take a tremendous amount of raw Irish sea moss, though: our top-rated raw Irish sea moss supplement comes in a 16-ounce bag; exceeding the maximum intake would require consuming over half of this bag in one sitting. 

Side effects

Too much Irish sea moss could cause you to exceed your upper limit on iodine intake. One of the benefits of Irish sea moss–its high iodine content–can also cause problems if you consume too much of it.

Excessive iodine intake can cause or exacerbate thyroid dysfunction, and can also cause gastrointestinal upset, nausea, vomiting, and diarrhea (5). As long as you don’t exceed about 200 grams of raw Irish sea moss per day, you’ll be well below your upper limit of 1.1 mg of iodine per day (6).

Though the majority of scientists believe that carrageenan found in Irish sea moss is safe, there is still some debate. Carrageenan is a gelatinous compound that constitutes about half of the mass of Irish sea moss, and gives it its rubbery, gel-like structure.

Because of this property, it’s a common additive in food, cosmetics, and other applications. There is some controversy over whether it has any negative effects on the body: while it’s been accepted as a safe food additive by regulatory agencies in both the United States and Europe, some scientists are concerned about the effects of small, degraded chunks of the molecules that make up carrageenan. 

This perspective is illustrated in a 2001 article in the journal Environmental Health Perspectives by J.K. Tobacman at the University of Iowa (7).

The author cites data from animal studies that show that degraded carrageenan molecules pose a risk of ulcers and cancer when delivered at a high dosage. The concern primarily centers on whether stomach acid can cause normal carrageenan to degrade into “low molecular weight” compounds. 

Other researchers point to a raft of evidence indicating that carrageenan as used in foods and as found in seaweeds and algaes is indeed safe; this perspective is illustrated in a 2002 follow-up article published in the journal Critical Reviews in Toxicology by two researchers at the University of Nebraska Medical Center (8).

Citing experiments in rats, mice, dogs, and non-human primates, the authors argue that long-term exposure to food-grade carrageenan preparations does not cause gastric ulcers or cancers.

Moreover, they show that carrageenan in the stomach and intestinal tract does not undergo degradation, and toxic effects are not seen even in long-term studies at doses far higher than those ever used in humans.

An exhaustive review in 2018 by the European Food Safety association, and later work published in 2020 in the journal Environmental Science and Pollution Research International, affirmed these findings (9,10).

Though the older research discussed above is the basis for most anti-carrageenan arguments that continue to this day, the latest science indicates that carrageenan is safe for human consumption. 

Recommended dosage

Unlike some other popular sea-sourced supplements like fish oil, there’s relatively little data on the optimal dosage of Irish sea moss supplements.

Of the few studies that have used carrageenan-based sea algae supplements to study human health, dosages vary widely: one study used a supplement providing carrageenan in an amount equivalent to about 500 mg of Irish sea moss (11).

Another study used naturally-sourced sea algae added to the usual diet of the study volunteers, in amounts that added up to a few hundred grams (not milligrams!) of raw sea moss (12). 

A better approach for determining optimal dosing comes from analyzing known safe amounts of two of the primary compounds found in Irish sea moss: iodine and carrageenan. 

Based on the amount of iodine found in wild-harvested Irish sea moss, one study pegged the maximum safe intake at just over 200 grams of raw Irish sea moss per day (13) (which is quite a lot–almost a full eight ounce bag!).

Whether carrageenan has any negative effects on the human body is still debated, but according to standards set by the European Food Safety Authority, the carrageenan dosage found in about 12 grams of raw dried Irish sea moss is known to be a safe intake level (14). 

Happily, this corresponds almost exactly to the typical dosage found in capsule-based Irish sea moss supplements, which usually provide 1200 mg of 10:1 Irish sea moss extract.

This is a reasonable place to start, though if you are looking to use Irish sea moss as a superfood and are not concerned about carrageenan content, you can take significantly higher doses of raw Irish sea moss.

It’s worth noting that the European Food Safety Authority amount is a very conservative lower estimate that is aimed at achieving absolute safety across all possible use-cases: people who eat carrageenan in the form of seaweed as a part of their typical diet, for example, likely exceed this amount on a regular basis with no apparent ill effects. 


Q: How is Irish sea moss produced? 

A: There’s not much production involved with Irish sea moss: it’s harvested raw from the sea, often in shallow waters in the Caribbean (though as the name suggests, Irish sea moss is also found off the coast of parts of Europe).

Then the Irish sea moss is washed to remove sand and dirt, and allowed to dry in open-air greenhouses. For raw Irish sea moss, there’s no additional processing!

Powdered Irish sea moss products and capsule-based supplements take the additional step of pulverizing the raw dried sea moss so it can either be packed directly into bags or extracted with a solvent and compressed into capsules. The minimal processing is one of the reasons why Irish sea moss is such a popular sea-based superfood. 

Q: How much Irish sea moss can you take?

A: The upper limits on Irish sea moss intake are dictated by its iodine content: if you consume above about 200 grams of raw dried Irish sea moss (about seven ounces), you bump up against the maximum recommended daily intake of iodine.

Some people are also concerned with excessive carrageenan intake; as a conservative estimate for carrageenan used as a food additive, the European Food Safety Authority has certified carrageenan intakes of up to 75 mg per kilogram of body weight as safe (15).

This level of carrageenan intake corresponds to about 12 grams of raw Irish sea moss, or a 1200 mg capsule dosage of 10:1 Irish sea moss extract, as is typical in capsule-based Irish sea moss supplements. 

Q: Is Irish sea moss bad for you? 

A: Some people argue that the carrageenan found in Irish sea moss (the fibrous, gelatinous compound that makes up the structural backbone of the Irish sea moss plant) causes stomach ulcers and cancer, pointing to animal studies done in the ‘80s and ‘90s that used high doses degraded carrageenan to induce these effects.

However, as discussed above in our side effects section, more rigorous research done in the last 30 years indicates that these worries are unfounded: carrageenan consumed as a part of your diet does not degrade in the stomach into these smaller compounds, and animals exposed to high doses of regular carrageenan show no ill effects.

In fact, much of the research on the health benefits of sea algae and sea moss (including Irish sea moss) suggests that much of the benefits of sea moss can be traced to the carrageenan content, including its ability to cut down on inflammation by blocking the infiltration of inflammatory cells, and by slowing or stopping the absorption of dietary lipids into your body, thereby lowering blood cholesterol. 

Q: Does Irish sea moss contain carrageenan?

A: Yes, Irish sea moss is rich in carrageenan. By volume, Irish sea moss is around half carrageenan–it gives it its thick, rubbery structure, and when isolated can be used as a thickener in cooking.

Carrageenan is also thought to be responsible for many of the health benefits of Irish sea moss found in research: scientists hypothesize that it blocks the absorption of lipids in the stomach, helps promote the growth of healthy, probiotic gut bacteria, and reduces levels of inflammation in your body. 

Q: Should you take Irish sea moss with bladderwrack? 

A: Bladderwrack is another type of sea algae that’s a popular supplement to combine with Irish sea moss: bladderwrack compliments Irish sea moss by boosting the iodine content, adding more fiber, and augmenting the heart health-promoting effects of Irish sea moss.

While taking Irish sea moss in combination with bladderwrack (or burdock root, another sea sourced algae that’s popular to combine with Irish sea moss) necessarily means you get a lower dosage of Irish sea moss, it’s a good idea if you are looking to get the benefits of multiple ocean-sourced supplements. 

Q: Is taking Irish sea moss good for weight loss?

A: Irish sea moss hasn’t been specifically investigated for use as a weight loss supplement. However, it does have several benefits that are helpful if you are on a diet to try to lose weight and improve your health.

First among these is its ability to lower blood cholesterol: improving heart health is one of the major benefits of losing weight, and some research suggests that taking Irish sea moss can lead to lower levels of blood cholesterol–possibly by blocking the absorption of cholesterol in your diet.

On top of that, animal research suggests that Irish sea moss can cut down on systemic inflammation, which is one of the effects of carrying excess weight. 

Q: How do you take Irish sea moss?

A: Irish sea moss can be taken in capsules, or as a powder or a gel added to a shake or smoothie. Capsules are the easiest way, though you have less flexibility with dosage.

Irish sea moss that’s provided in powder form can be easily added to a protein shaker and mixed up with your favorite protein powder.

One of the most popular ways to take Irish sea moss, though, is to prepare a gel from raw dried Irish sea moss. You can take the raw sea moss and add it to a bowl, then cover it in cold water and put it in the refrigerator for 24 to 48 hours.

This will soak and reconstitute the fibrous carrageenans that make up the structure of the Irish sea moss. Then you can add the sea moss (and the water) to a blender and blend until it’s smooth. After another hour or two in the refrigerator, it should congeal with a gel-like texture.

Many health food experts attest that this raw preparation of Irish sea moss is the best way to lock in the nutrients, vitamins, and minerals that are found in the natural plant material. 

Q: Is Irish sea moss good for cleansing diets? 

A: Irish sea moss, especially when prepared by soaking and blending raw dried Irish sea moss, is widely used for short-term cleanses.

Though it’s high in trace minerals and nutrients like iodine, magnesium, and calcium, Irish sea moss has essentially no calories. While this means it’s great for a short-term cleanse, it’s not going to sustain you for longer cleanses. Its lack of caloric content likely explains why it is most popular for short-term cleanses of just a day or two in length.

Q: Is Irish sea moss good for metabolic health?

A: In addition to its lipid-lowering and inflammation-fighting properties, one of the most interesting potential applications of Irish sea moss is its potential for increasing your resistance to the metabolism-damaging effects of an unhealthy diet.

When we say “metabolic health” here, what we mean is your body’s ability to regulate blood sugar levels via insulin. This ability is deteriorated in people who have metabolic syndrome, and completely dysregulated in people with type 2 diabetes.

Since weight gain and an unhealthy diet are two of the primary causes of poor metabolic health, the potential for Irish sea moss to combat these causes is particularly exciting. To date, though, the only evidence supporting this ability comes from animal models–research on Irish sea moss and metabolic health in humans is still forthcoming.
