If you’ve scrolled through TikTok recently (who hasn’t, the algorithm is magic), there’s a chance you’ve seen videos about a “superfood” called sea moss. It’s hard to avoid if even Kim K is endorsing it.
Proponents swear sea moss supports anti-aging, detox, skin health, a robust immune system, and healthy cholesterol levels.
However, munching on moss doesn’t exactly sound enticing. So, we did a deep dive to see what all the buzz was about.
Today, we’ll cover the efficacy and safety of this trending wellness supplement. Plus, we’ll cover our picks for the 8 best sea moss supplements on the market.
Sea moss (Chondrus crispus) is edible algae, also known as Irish sea moss or Irish moss. It looks like frilly red or purple lettuce growing in tidal pools and on rocky outcrops along the British, European, and North American coastlines.
Sea moss is mainly harvested from a jelly-like substance called carrageenan, a vegan-friendly emulsifier, thickener, and binder. But it’s also in demand as a health supplement. Anecdotal evidence claims it promotes blood sugar balance, joint health, respiratory health, and heart health.
So, how much of this is true?
Like other sea veggies – like kelp and spirulina – sea moss is a source of essential nutrients that may be missing from a Standard American Diet. This includes omega-3 fatty acids, iodine, magnesium, calcium, phosphorus, potassium, zinc, and vitamins A, B, and K. In fact, it contains all 92 minerals your body needs for overall health and well-being.
It’s a nutrient “insurance policy” of sorts. But, unlike synthetic mineral supplements, sea moss is a real food that’s easy to assimilate.
It’s especially rich in bioavailable iodine, a mineral crucial for thyroid health and a well-performing metabolism. Sea moss is worth exploring if you have a thyroid disorder, sluggish thyroid function, or low energy levels.
Let’s look at more of the health benefits of sea moss. Keep in mind the current research is sparse, and most of the data is from animal and lab studies.
Seaweed is a source of digestion-resistant prebiotic fiber, which is “food” for the trillions of bacteria in your digestive system.
This rodent study found sea moss changed the gut microbiome composition for the better. It improved gut health and immune function.
We need clinical studies before we can take this as gospel – but it is promising, nonetheless.
One of the few human studies on sea moss suggests it helps you get more out of your workout if you struggle with muscle pain, weakness, and fatigue.
However, those claiming it’s a performance-enhancing supplement are stretching the truth. It’s more likely to give you a boost by upping the nutrient density of your diet.

We ranked these supplements, but we want you to decide on the best product for your needs.
Here are some factors we considered when researching the best sea moss supplement.
The FDA doesn’t regulate the supplement industry. This makes it easy for dodgy companies to make false claims on their product labels.
The growing demand for sea moss makes it susceptible to unscrupulous companies flooding the market with tainted products to make a quick buck.
For this reason, we prioritize trusted companies that source ingredients responsibly and safely. They adhere to cGMP regulations and use third-party testing. Many companies also provide test results online.
Buying from our list ensures you’re getting high-quality natural sea moss.
By nature, sea moss is at risk of contamination by heavy metals, pollutants, and toxins. You need a product grown under the strictest conditions.
We looked for products using wildcrafted Irish sea moss from sustainable sources (rather than pool-grown). We also prioritized organic sea moss free from junk fillers and additives.
Plus, we boosted supplements with other ingredients for added health benefits. This is the case with Codeage Wildcrafted Sea Moss.
The supplements on the list offer 250–1200 mg of sea moss per serving. Some people prefer starting with a lower dose and building up.
We listed sea moss capsules, chews, gummies, and gel so you can pick what works best for you.
Supplementing with high-quality sea moss shouldn’t put you out of pocket.
We weighed the cost against the number of servings, the dose, and the quality to find the best value for money.
Plenty of anecdotal evidence claims sea moss contributes to weight loss by enhancing thyroid function. So far, it’s purely speculative.
That said, marine algae may contain compounds with anti-obesity properties. However, the weight loss benefits of sea moss aren’t backed by human studies yet.
Sea moss is a good source of antioxidants (these guys fight free radicals and protect your cells from oxidative damage). Preclinical research suggests one of these antioxidants, fucoxanthin, may inhibit colorectal cancer.
However, human trials haven’t studied sea moss as an anticancer supplement. I’m hopeful we’ll see more research in this area soon.
Various seaweeds, microalgae, and macroalgae are lumped together as sea moss.
However, Irish sea moss from the Chondrus crispus species of red algae is the most reputable form.
Sea moss isn’t FDA-regulated, so we don’t have an official recommended dose. Most product labels suggest taking between 500-1200 mg daily.
Consuming up to 4 grams of sea moss daily appears to be safe for most people (if you invest in a reputable supplement).
However, there is a risk of consuming excess iodine from sea moss, which can become toxic. In addition, some people experience mild digestive discomfort from the carrageenan in sea moss.
We need more research on the best dosage and the potential side effects of sea moss supplements. As always, speak to your doctor before taking a new dietary supplement.
