1. What is sea moss?
Sea moss is a type of red algae found growing on coasts of the Northern Atlantic Ocean. This algae is known as sea moss, Irish moss, red seaweed, carrageen moss or its scientific name: Chondrus crispus. The algae is considered edible and is sold in all types of forms, from its raw, natural form to gel to powder and more.
2. Potential benefits of sea moss
Sea moss has become popular as a healthy ingredient because of its nutritional profile. This algae is rich in many vitamins and minerals, including calcium, iron, magnesium, potassium, and iodine. It can also be a good source of fiber.
“Sea moss has anti-inflammatory properties, which can help reduce inflammation and swelling in the body,” Krutika Nanavati, registered dietitian and medical advisor for ClinicSpots. “It is also high in antioxidants, which can help protect your cells from damage caused by free radicals. Additionally, sea moss is known for its skin-repairing benefits; it helps to nourish and hydrate the skin while providing essential vitamins and minerals that promote healthy skin. It can even help boost your metabolism.”
Other potential benefits include strengthening the immune system, supporting thyroid health, lowering blood pressure, and boosting gut health.
Some studies in animals have shown promising health benefits of sea moss consumption, but more research is needed to determine the impacts on humans.
3. Concerns about sea moss
There are precautions to consider if you’re looking into incorporating sea moss in your diet.
Although the high iodine content in sea moss can be potentially beneficial, it can also be harmful, especially for anyone with thyroid conditions and/or taking medications.
Although the high iodine content in sea moss can be potentially beneficial, it can also be harmful, especially for anyone with thyroid conditions and/or taking medications.
Sea moss can take in contaminants from the water, meaning it could contain harmful pollutants and heavy metals. Consumers could be allergic to sea moss, especially for anyone who is allergic to seaweed, shellfish, or iodine.
“You should also be aware of any possible allergic reactions when consuming sea moss,” Nanavati warned. “It's always wise to start with a small amount and monitor your body's reaction before consuming more.”
You should also be critical when shopping for sea moss products, which are often labeled with misleading claims about its benefits.
“While there is some scientific evidence to support the potential health benefits of sea moss, not all of these benefits have been studied in humans,” said Johna Burdeos, registered dietitian. “Many of the studies that have been conducted have been small-scale or have used animal models, and more research is needed to fully understand the effects of sea moss on human health.”
4. How to incorporate sea moss in your diet
There are many ways to add sea moss to your diet. But first, you should talk to your healthcare providers to determine if sea moss is right for you, especially if you have health concerns, including hyperthyroidism or hypothyroidism.
Sea moss doesn’t have the most appealing taste or texture. Typically, it can taste unsurprisingly like seafood. It is often sold as a gel, which offers a more mild flavor ideal for blending into smoothies, sauces, or soups. You can also find it dried or in powder forms. Start with a small amount, only up to about a tablespoon, as you introduce this ingredient into your diet.
Because sourcing is a concern, make sure to choose trusted, reputable brands that test sea moss products for any contaminants.
“The most commonly consumed varieties are Chondrus crispus, or Irish Moss, and Gracilaria spp., also known as Caribbean Red Moss,” Nanavati said. “Both of these varieties are generally recognized as safe by FDA.”
Still, be mindful when shopping: sea moss is considered generally safe by the FDA, but supplements containing this ingredient are not FDA-approved.
While you may consider adding sea moss to your smoothies or try out sea moss supplements, experts still recommend a well-balanced diet over supplements for the best potential health outcomes.
