Sea moss is one of the most popular nutritional supplements in the world, and is used by millions of people daily. Many health and wellness influencers claim that sea moss can have life-changing health benefits while others are more skeptical.
But is sea moss proven in medical studies to have any specific health benefits? Are there any health risks or dangers associated with its use? What’s the best sea moss brand? And how do real users rate and describe the effects of sea moss use?
In this article we’ll answer all of these questions and more as we review clinical studies on sea moss to determine whether it actually has proven health effects.
We’ll also explain if it can be dangerous or cause side effects, share our top sea moss brand recommendation, and highlight real, unsponsored sea moss user reviews.
What Health Benefits Does Sea Moss Have?
Sea moss is a general term that is used to refer to a few different species of seaweed. Eucheuma spinosum is the botanical name for the sea moss native to Indonesia, and Chondrus crispus, also called Irish sea moss, is another widely-cultivated variety. Both have been studied in clinical research.
General nutrition is the first research-backed benefit of sea moss consumption. A medical review published in the European Journal of Clinical Nutrition found that the minerals, dietary fibers and phytonutrients in sea moss may contribute to a reduction in disease risk.
Many Americans eat a nutritionally-deficient diet, and all of the different nutrients in sea moss can be effective for preventative health, somewhat like a multivitamin.
Cold and flu prevention is another potential health benefit of sea moss. A 2020 medical review found that sea moss has antioxidant, anti-inflammatory and antiviral effects which may help consumers reduce the risk of illness.
Sea moss contains a compound called fucoidan which reduces the body’s production of proinflammatory cytokines and has direct effects against influenza A, hepatitis B and HIV according to the above-linked medical review.
Fertility and libido is what sea moss is frequently used for. While we can’t identify any clinical trials with human trial participants proving this effect, a 2021 animal study found that sperm count increased by over 35% and testosterone levels increased by over 20%.
As we explained in our review of black seed oil, results from animal studies don’t necessarily mean the same results will apply in humans, but the hormone systems of all mammals are similar so this early research is promising.
Overall, sea moss has the potential to improve human health due to its rich nutritional status. We would consider it a functional food rather than a supplement because it can be consumed whole and no processing is required.

Are There Any Health Risks to Sea Moss Use?
One of the most frequently-discussed risks of sea moss use is related to iodine overconsumption. Iodine is a trace mineral that can cause thyroid issues when consumed at too high of a quantity. However, we don’t believe this is an issue based on medical research.
A medical review published in the Environmental Science and Pollution Research journal examined the risk of iodine intake from two common types of sea moss. The study authors found that there was no health risk at normal intake levels of around 4 grams per day, and at this level the iodine intake would actually be beneficial.
Only at an intake of 286 grams a day of sea moss consumption was there a risk of iodine toxicity, and this dose is far higher than what most consumers would take daily.
A meta-study published in the Nutrition Reviews journal examined the risks of sea moss intake and concluded that there were no specific risks beyond potential environmental contamination, which exists for all food products grown outdoors (including rice, oats, etc).
Overall, we do not consider sea moss use likely to cause side effects, but sourcing from quality suppliers is important.
Is Sea Moss Gel Better Than Regular Sea Moss?
Sea moss gel is the same product nutritionally as whole sea moss or sea moss powder. It’s just processed differently.
The gel is created by soaking sea moss, blending and cooling it. The consistency and density of the solution changes, making it more “gel-like,” and it can be easier to take in this form.
We recommend that consumers be wary of any companies making claims that sea moss gel is healthier than any other format of sea moss, because it suggests a lack of understanding about this food, and suggests a low-quality brand.
A YouTube channel called “Divas Can Cook” has a video on how to make sea moss gel:
