Each serving of Nutra Remedies contains 750mg of Irish sea moss, 750mg of bladderwrack, 750mg of burdock root, and 10mg of black pepper extract. However, it’s one of the most expensive at $39.97 per bottle, and none of the ingredients are organic.

Nutra Remedies appears to have several hundred positive reviews on their website, but the company hides negative reviews. Because of this, we can’t get a good idea of the customer experience. Still, it may be worth choosing if you want a more potent dose of Irish sea moss, bladderwrack, and burdock root.

Maju Wild Irish Sea Moss

Maju Wild Irish Sea Moss

Maju Wild Irish Sea Moss is one of Amazon’s most popular products, backed by 3,200+ reviews and a 4.5/5 star rating. According to Maju, their sea moss can support skin health, digestion, joint health, and immune function.

Each two-capsule serving of Clinical Effects Sea Moss contains 500mg of organic Irish moss, 500mg of organic bladderwrack, 400mg of organic burdock, and 5mg of BioPerine®.

Unlike most of the other products on our list, you can only buy sea moss from Clinical effects directly through their official website. One bottle will cost you $34.95 per bottle, but discounts are given on multiple bottle orders. If you don’t mind paying the premium, Clinical Effects Sea Moss is a decent option.

Secret Element Organic Sea Moss

Secret Element Organic Sea Moss

Secret Element Organic Sea Moss is primarily found on Amazon. Backed by over 1,600 reviews, Secret Element claims their sea moss can provide typical benefits, like better digestive health, improved immune system function, and thyroid support.

In every 3-capsule serving, there is a 2,000mg “proprietary blend” of Irish sea moss powder, bladderwrack powder, and burdock root powder. Sadly, Secret Element does not disclose every dosage of each ingredient, which is slightly problematic.

One bottle of Secret Element Irish Sea Moss will cost you $16.95 per bottle. We would’ve ranked it higher but could not because of the lack of transparency as to the dosage of each ingredient.

Double Wood Supplements Irish Sea Moss

Every two-capsule serving of organic sea moss from Nutrivein contains a “proprietary blend” of 1600mg of organic Irish moss powder, organic bladderwrack powder, and organic burdock root powder. They don’t disclose exactly how much ingredient is in each capsule.

It’s tough to rank Nutrivein higher because of the lack of transparency about the dosage of each ingredient. We prefer products that identify their contents and the ingredients in each serving. Still, 5,800+ customers can’t be wrong, so if you don’t mind the proprietary blend, Nutrivein may be right for you.

The only downside to Atlantic Gold is that their pricing is on the more expensive side. For example, one bottle of Atlantic Gold Sea Moss capsules is priced at $47, more than double the average price. The quality of sea moss is top-quality, though, and well worth buying if you can afford to spend the extra money. It may be too expensive if you’re on a tight budget.

Our Top Ranking Factors for The Best Sea Moss Supplements

When evaluating every sea moss supplement, we used a strict set of criteria to determine which products are worth buying and which are better off avoided. Here are the ranking factors we used:

Sea Moss Dosage

If you’re buying a sea moss product, you are buying it for the Irish sea moss. This is why sea moss dosage was the most critical factor in our rankings. We preferred supplements with doses in the clinically proven effective range – anywhere between 400mg to 800mg per day.

Complementary Ingredients

While Irish sea moss is beneficial on its own, other natural ingredients are known to enhance its effectiveness. For example, burdock root and bladderwrack enhance sea moss benefits. Likewise, black pepper extract appears to help your body absorb the beneficial compounds in sea moss, potentially amplifying the benefits of sea moss.

Organic Certification

Like every type of supplement, we found organic sea moss supplements to be of higher quality. Therefore, we ranked products that used organic sea moss higher than those that did not use organic sea moss.

Wild-harvested Sea Moss

When buying a sea moss supplement, you must purchase wild-harvested sea moss. This is because wild-harvested sea moss is less likely to have any heavy metal accumulation. It is less likely to be grown with pesticides.

Manufacturer Reputation

Many supplement companies selling sea moss have a proven history of producing high-quality products. Others are new and haven’t established themselves yet. While we didn’t ignore newer companies, we still preferred supplement companies with a strong reputation for producing high-quality supplements that are both safe and effective.

Honest Claims

Some supplement companies make exaggerated claims about what their products can potentially do. Others are honest about the potential health benefits of sea moss. We preferred companies that made realistic, genuine claims about the potential health benefits of using their product.


Price is important because you don’t want to be ripped off by paying more than you need. Conversely, you don’t want to buy a cheap product with inferior quality ingredients or under-dosed. This is why we tried to find products within a price range we felt appropriate given the costs to produce, manufacture, and ship sea moss.

Money-back Guarantee

While sea moss is highly beneficial, no supplement has a 100% satisfaction rate. It’s just not the nature of supplements. This is why if you don’t feel any benefits, then you should be able to get your money back. This is why we ensured every product on our list had at least a 30-day money-back guarantee.

Customer reviews

The best way to determine which sea moss supplements are worth buying and which are better avoided is to read customer reviews. Were most customers satisfied with their experience? Were there side effects? Did they find the product was appropriately priced? Would they recommend the product to their friends or family? These are all questions we needed to answer.

Science-Backed Health Benefits of Irish Sea Moss

Irish sea moss has only recently begun to be examined for its potential health benefits in clinical settings. However, recent research suggests there are clear benefits to taking sea moss.

We’ll examine the most science-backed health benefits below:

Sea moss is incredibly nutritious. Sea moss purportedly contains 92 of the 102 essential vitamins and minerals the body needs to survive. Irish sea moss is an excellent source of iron, magnesium, iodine, zinc, copper, phosphorus, calcium, dozens of other vitamins and minerals, and phytonutrients that combat inflammation and support your overall health and wellness.

Sea moss can potentially help improve thyroid health and overall function. Sea moss is rich in iodine, which is directly involved in thyroid hormone production. Studies have found a growing percentage of adults are developing an iodine deficiency and, in turn, have poor thyroid function. This is why those suffering from poor thyroid function may benefit from using Irish sea moss.

Irish sea moss may improve gut health. Several studies have found that sea moss is rich in fiber and live bacteria, contributing to a healthy gut microbiome. Fiber also helps keep the digestive “moving,” so to speak, which can alleviate minor digestive issues such as bloating or constipation.

Newer research suggests that sea moss may contribute to healthy weight loss. Irish sea moss is rich in fiber that can reduce appetite by making you feel fuller for longer. Sea moss also contains an antioxidant known as fucoxanthin, which has been shown to activate brown fat and lipolysis in several studies.

Irish sea moss is commonly used to lower cholesterol levels and improve blood flow. Fucoxanthin, the same antioxidant that supports weight loss, appears to help limit blood sugar spikes. It also seems to reduce total cholesterol, which may improve blood flow. Better blood flow is linked to a lesser risk of developing conditions like heart disease.

Irish sea moss may improve immune system function. A study on salmon found that Atlantic salmon that ate seaweed enhanced immune response and modulation. Researchers believe the antioxidants found in sea moss are responsible for these benefits.

As you can hopefully now see, digestive health, immunity, and thyroid health appear to be the most common benefits of sea moss. Numerous research studies are currently underway and are more likely to confirm these benefits and discover new health benefits.

Side Effects of Sea Moss

In the available published research involving sea moss, there haven’t been any reports of any severe side effects while using sea moss. This is why most users generally see sea moss as safe and is tolerated well.

This is not to say it may be suitable for everyone. If you’re on thyroid medication, you may want to be careful since sea moss appears to improve thyroid function. Therefore, it may make your thyroid too active. Likewise, it isn’t known if sea moss is safe for pregnant or nursing mothers.

As we briefly mentioned, sea moss does affect thyroid medication because it is a rich source of iodine. This is why you should be careful using sea moss – particularly in bulk form. Capsules and gummies are unlikely to contain enough iodine to cause serious issues.

Likewise, look for sea moss supplements that are third-party tested because some sea moss products can contain heavy metals. This is a naturally occurring process; heavy metals should be extracted and removed.

In general, sea moss is overwhelmingly safe and should not cause adverse reactions. If you have a prescription medication or a severe condition, speak to your doctor before using sea moss to ensure it is right for you.

Irish Sea Moss Dosage

Like most supplements, there is no official recommended dosage associated with Irish sea moss. Most studies seem to report a dosage of anywhere between 500mg to 1,000mg a day to be effective. This is why most supplements contain a dosage in this range.

Some products use a higher dosage of 1,000mg+, but it isn’t known if it is more effective. This is why we recommend you stick to a dosage between 300-700mg daily, as this appears effective yet safe.
