Sea Moss Is Everywhere Right Now, But What Can It Actually Do For You?

Sea moss has had quite the glow up. Whereas before, most people would consider it an especially slimy supplement, now you'll find it snuggled on the shelves at Erewhon, marketed as a cure-all for glowing skin, immunity, and gut health. Perhaps it's this reason why the marine marvel has been touted as the latest and greatest superfood. But is sea moss really as good for you as people say? Sea moss, a nutrient-dense form of red algae, is rumored to help with heart and gut health, skin elasticity, and even weight management. But we're going to need a little more proof before stomaching a spoonful of algae gel. To get to the bottom of these claims, we turned to registered dietitians to find out what sea moss can (and can't) do for you. Read on to learn more about the aquatic wonder, including real benefits, side effects, and tips for incorporating sea moss into your own routine.

Mascha Davis, MPH, RDN, is a registered dietitian and the author of "Eat Your Vitamins." What Is Sea Moss? Sea moss, also known as Irish moss or red seaweed, is a type of red algae that grows along the rocky parts of the Atlantic coastlines of Europe and North America. "While it's gaining a lot of popularity in the wellness world now, it's actually been consumed as part of traditional diets, especially in coastal regions like the Caribbean, Ireland, and parts of Asia," says Jen Scheinman, MS, RDN, CDN. Known for its high nutrient content, sea moss is a great source of iodine, potassium, calcium, and vitamins A, D, E, and K. It's often used in food for its gelling properties, which means it often comes in gel form. Scheinman explains that "while there are not a lot of studies done with sea moss, it's purported to have benefits ranging from thyroid health to gut health." "A four-tablespoon serving of Irish sea moss provides 10 percent of the daily value (DV) for iron, 7 percent of the DV for magnesium, and 4 percent of the DV for zinc, all for only 10 calories," says Mascha Davis, MPH, RDN. Sea moss supplements are typically sold in gel, gummy, or tablet form. Sea Moss Health Benefits Here's a list of what sea moss can do for your health, according to experts. As a note, make sure to consult with a doctor before starting any new medication or supplement, especially since supplements are not regulated by the Food and Drug Administration (FDA). Improved thyroid function: One remarkable benefit of sea moss is its high iodine content, which is crucial for proper thyroid function. This vital nutrient helps in the production of thyroid hormones, which are responsible for regulating metabolism, energy production, and cellular repair in the body. That said, "if you are considering using sea moss and you have a thyroid disorder, you'll definitely want to connect with your healthcare practitioner, as too much iodine can have a negative impact on the thyroid," Scheinman cautions. Stronger immunity: Sea moss is known for its potential to support a healthy immune system. Packed with antioxidants and vitamins such as vitamin C, sea moss may play a role in bolstering the body's defenses against common illnesses and infections. Healthier skin: There's a reason people start to see a glow after taking sea moss. The supplement is high in sulfur, which is often dubbed "nature's collagen" and used as a therapeutic agent in a variety of dermatologic disorders. It may enhance the elasticity and suppleness of the skin, promote faster healing of cuts and burns, and provide relief for conditions such as eczema and psoriasis. Better gut health: "Sea moss is a good source of fiber and prebiotics (nutrients that support your gut microbiome), so it may have a beneficial effect on gut health," Scheinman says. Sea moss also supports digestive health thanks to its high mucilage content. This gel-like substance may help gut health by easing discomfort and aiding in the smooth transit of food through the digestive tract. Reduced inflammation: The high antioxidant content of sea moss means that it could help lower inflammation and potentially lower your risk of chronic illness. This includes conditions like heart disease, some forms of cancer, and metabolic conditions like type 2 diabetes, Scheinman says. Sea Moss Side Effects While sea moss is often celebrated for its health benefits, it's important to be aware of its potential side effects, too. Overconsumption can lead to an excess of iodine, which might disrupt thyroid function. Additionally, because sea moss acts as a blood thinner, those taking anticoagulant medications should exercise caution and speak with a doctor before using sea moss. On that note, it's always advisable to consult with a healthcare provider before incorporating sea moss, or any new supplement, into your diet. Also worth nothing: "Sea moss might pose a risk of elevated heavy-metal intake since seaweed has a tendency to absorb and accumulate heavy metals," Davis tells PS. Plus, "eating too much sea moss can trigger an upset stomach, diarrhea, and/or constipation," Scheinman says. How to Add Sea Moss to Your Diet Once you get the go-ahead from your doctor, adding sea moss to your diet is simple (with a little know-how). You can also take sea moss in capsule form and skip the recipes, but here are some more creative ideas to add sea moss into your routine: Smoothies: Add sea moss gel to your favorite smoothie recipe for a boost of nutrients. You'll even find it in Hailey Bieber's viral Strawberry Glaze smoothie at Erewhon. Teas and beverages: Stir a spoonful of sea moss gel into hot teas or homemade juices. Soups and stews: Mix sea moss gel into broths or stews to thicken them and add more minerals. Baked goods: Use sea moss as a healthy additive in bread, cakes, or muffins. Sauces and dressings: Blend sea moss into sauces, dressings, or dips for added texture and nutrients. Breakfast bowls: Top off oatmeal or yogurt bowls with a spoonful of sea moss gel. Desserts: Incorporate sea moss gel into dessert recipes like puddings or vegan jellies for a healthful twist. 165578
