The best sea moss supplements to buy, tried and tested by experts

<p>Sea moss has moved beyond its niche roots to popular supplement. But with gels, powders, liquids, tablets and capsules all available, which is the best sea moss to buy?</p><p data-start="629" data-end="788">Also known as Irish moss, sea moss is valued for its natural iodine content, which contributes to normal thyroid function, and <a href="https://www.bbcgoodfood.com/review/best-fibre-supplements" target="_blank" rel="noopener">fibre</a>, which supports digestion.</p><p data-start="790" data-end="1055">You’ll find sea moss in a range of formats, from Irish sea moss gel and liquid extracts to powders, tablets and capsules. Some products contain sea moss alone, while others include additional algae and seaweed-derived ingredients such as bladderwrack and spirulina.</p><p data-start="1057" data-end="1677">The best format for you will depend largely on personal preference. For example, gels and liquids, such as <a href="https://www.awin1.com/cread.php?id=489797&amp;clickref=bbcgoodfood-1017543&amp;awinmid=76738&amp;p=https%3A%2F%2Fuk.iherb.com%2Fpr%2Ftrue-sea-moss-sea-moss-gel-superfood-blue-spirulina-and-raspberry-16-fl-oz-473-ml%2F144571" target="_blank" rel="sponsored" data-start="1151" data-end="1293">True Sea Moss Sea Moss Gel</a> and <a href="https://www.awin1.com/cread.php?id=489797&amp;clickref=bbcgoodfood-1017543&amp;awinmid=76738&amp;p=https%3A%2F%2Fuk.iherb.com%2Fpr%2Fvitamatic-sea-moss-liquid-mixed-citrus-berry-2-fl-oz-59-ml%2F154022" target="_blank" rel="sponsored" data-start="1298" data-end="1414">Vitamatic Sea Moss Liquid</a>, can be added to food or drinks.

Some labels state the physical quantity of an extract, while others advertise the much larger quantity of raw sea moss the extract is said to be equivalent to. A product labelled as providing 1,200mg equivalent, for example, may contain a much smaller quantity of concentrated extract.</p><p data-start="4690" data-end="4933">Unlike vitamins and minerals with recognised daily reference values, there is no established evidence-based daily dose of sea moss.

We found the raspberry flavour pleasantly fruity, with only a slight seaweed-like note. The smooth, jelly-like texture can be eaten from the spoon or blended into smoothies and yogurt.</p><p>Each 30g serving contains 3mcg iodine, while the ingredient list includes wildcrafted sea moss, raspberry puree and blue spirulina. The product page also states that it is third-party tested and makes a ‘no heavy metals’ claim. It is Non-GMO Project Verified, certified vegan and certified gluten-free. The exact sea moss species and amount per serving are not given, so it is harder to compare its potency with capsules or powders.</p><p>At £1.74 per day, it is one of the more expensive formats and the 473ml jar lasts only 15 servings. It also needs refrigeration after opening and should be used within four weeks. Still, the flavour, ready-made texture and clear iodine labelling make it our strongest gel option.</p><p><strong>Available from:</strong></p><ul><li><a href="https://www.awin1.com/cread.php?id=489797&amp;clickref=bbcgoodfood-1017543&amp;awinmid=76738&amp;p=https%3A%2F%2Fuk.iherb.com%2Fpr%2Ftrue-sea-moss-sea-moss-gel-superfood-blue-spirulina-and-raspberry-16-fl-oz-473-ml%2F144571%3Futm_source%3Dchatgpt.com" target="_blank" rel="sponsored">iHerb (£26.15)</a></li></ul><h3 id="nutravita-high-strength-sea-moss-5000mg-tablets-3735e765">Nutravita High Strength Sea Moss 5000mg Tablets</h3><p>Available from <a href="https://nutravita.com/products/sea-moss-tablets" target="_blank" rel="sponsored noopener noreferrer">Nutravita (£19.99)</a>, <a href="https://www.amazon.co.uk/5000mg-Sea-Moss-Tablets-Energy-Yielding/dp/B0DBJ1TLWF/ref=asc_df_B0DBJ1TLWF?tag=bbc00-21&amp;ascsubtag=bbcgoodfood-1017543" target="_blank" rel="sponsored">Amazon (£14.99)</a></p>

The species is also clearly identified as Chondrus crispus Stackhouse.</p><p>We found the two-tablet serving simple to fit into a routine, with no seaweed taste, measuring or refrigeration to worry about. The tablets are vegan and made in the UK, although the formula does include bulking agents and a tablet coating rather than sea moss alone.</p><p>At 10p per day, this is one of the most economical sea moss products we tested.

"You’ll see it listed on food labels as ‘carrageenan’.</p><p>"Vegan-friendly and a good all-round emulsifier, carrageenan is commonly used by food manufacturers. That said, most of us are more likely to take sea moss as a supplement, primarily for its ability to support <a href="https://pubmed.ncbi.nlm.nih.gov/25006699/" target="_blank" rel="noopener">thyroid function</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/29425873/" target="_blank" rel="noopener">digestion</a>, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5992350/" target="_blank" rel="noopener">immunity</a> and <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8004118/" target="_blank" rel="noopener">skin health</a>."</p><h1 id="which-form-of-sea-moss-is-best-69e2632b"><a id="BESTSEAMOSS3"></a>Which form of sea moss is best?</h1><p>The gel is often considered the most bioavailable and therefore effective, because the mucilage and nutrients in the seaweed have already been partially broken down and hydrated, making it easier to absorb.</p><p>Kerry says: "Raw forms of gel retain more of the natural compounds and nutrients than the processed powders and capsules, although the quality of the source ingredient is also relevant. For example, wild harvested sea moss is generally considered richer and more diverse in nutrients than sea moss cultivated in tanks."</p><h1 id="when-is-the-best-time-to-take-sea-moss-e845575e"><a id="BESTSEAMOSS4"></a>When is the best time to take sea moss?</h1><p>Ideally, take sea moss first thing in the morning and on an empty stomach. Kerry says: "This is because the minerals it provides, such as iodine, potassium and iron, are better absorbed when the stomach is empty.</p><p>"Providing the critical nutrients for metabolism (iodine) and energy (iron) as your day starts, may give you the boost needed to optimise calorie-burning and sustain flagging energy levels. Other nutrients, like potassium and magnesium may provide your nervous system with the support needed to enhance your focus and thinking."</p><h1 id="can-sea-moss-interact-with-medicines-or-supplements-3f469290"><a id="BESTSEAMOSS5"></a>Can sea moss interact with medicines or supplements?</h1><p>"If you’re on the blood thinning medication warfarin, your GP or registered dietitian may suggest you monitor the amount of vitamin K-rich foods, like seaweed, in your diet. This is because by maintaining consistent amounts of vitamin K you may help stabilise the time it takes for your blood to clot," says Kerry.</p><p>Seaweed contains high levels of the mineral, potassium, so any medication that works by raising potassium levels in the blood, such as certain blood pressure medications and diuretics, should be carefully monitored.</p><p>Kerry says: "Many of us <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8377299/">take multiple supplements</a>, including high dose products, if this is relevant for you, be aware that sea moss is rich in iodine, vitamin K and potassium and taking it alongside other multi-nutrient products may lead to higher than optimal intakes of these nutrients. Always consult your GP or healthcare practitioner if you are unsure about the products you are taking, and if you are on prescribed medication."</p><h3 id="read-more-health-and-wellbeing-product-reviews-41adcfe8">Read more health and wellbeing product reviews</h3><p><a href="https://www.bbcgoodfood.com/review/best-collagen-supplements-tried-and-tested" target="_blank" rel="noopener">Best collagen supplements</a><br><a href="https://www.bbcgoodfood.com/review/best-protein-powders" target="_blank" rel="noopener">Best protein powders</a><br><a href="https://www.bbcgoodfood.com/review/best-vegan-protein-powders" target="_blank" rel="noopener">Best vegan protein powders</a><br><a href="https://www.bbcgoodfood.com/review/best-protein-bars" target="_blank" rel="noopener">Best protein bars</a><br><a href="https://www.bbcgoodfood.com/review/best-vegan-protein-bars" target="_blank" rel="noopener">Best vegan protein bars</a><br><a href="https://www.bbcgoodfood.com/review/best-vitamin-c-supplements" target="_blank" rel="noopener">Best vitamin C supplements</a><br><a href="https://www.bbcgoodfood.com/review/best-magnesium-supplement" target="_blank" rel="noopener">Best magnesium supplements</a><br><a href="https://www.bbcgoodfood.com/review/best-iron-supplements">Best iron supplements</a><br><a href="https://www.bbcgoodfood.com/review/best-vitamin-d-supplements" target="_blank" rel="noopener">Best vitamin D supplements</a><br><a href="https://www.bbcgoodfood.com/review/best-omega-3-supplements" target="_blank" rel="noopener">Best omega-3 supplements</a><br><a href="https://www.bbcgoodfood.com/review/best-vitamin-b12-supplements" target="_blank" rel="noopener">Best vitamin B12 supplements</a><br><a href="https://www.bbcgoodfood.com/review/best-probiotic-supplements" target="_blank" rel="noopener">Best probiotic supplements</a></p><p><em>Always keep supplements out of the reach of children. Unless otherwise stated we tested products available in the UK market that are suitable for adults. Check the product label and ingredients before purchase to ensure it is appropriate for your individual circumstances.</em></p><p><em>A qualified nutritionist (MBANT), Kerry Torrens is a contributing author to a number of nutritional and cookery publications including Good Food.
