In general, it's probably best to consume sea moss in moderation because of these unknowns. The nutrients in sea moss can vary depending on the environment in which it was grown. It may contain high levels of iodine or heavy metals. However, current research has not found that sea moss contains toxic levels.
Depending on the water in which the varieties of sea moss grow, they can contain high levels of heavy metals. Heavy metals are toxic to humans and, when ingested in large quantities, can prevent or interrupt cellular processes such as cell growth, proliferation and repair. This is especially dangerous for pregnant or breastfeeding women, so always check with your doctor before adding sea moss to your diet. Sea moss, or Irish moss, is a type of seaweed that people can add to food or take as a nutritional supplement.
Sea moss is naturally rich in minerals and vitamins, and may have some potential health benefits if used regularly. There is some research that supports the idea that sea moss may help maintain immune health, gut health, weight loss, and thyroid function. However, we need more studies to know for sure. It's generally considered safe to take sea moss in small doses.
Keep in mind that it may contain high levels of heavy metals and iodine, so it's best to use it only in moderation. Archaeologists estimate that humans have been harvesting and using sea moss for more than 14,000 years. Research published in BMC Complementary Medicine and Therapies found higher levels of immune antibodies in rats that had eaten sea moss. In addition, sea moss species contain fatty acids, polyphenols, carotenoids, complex polysaccharides, and live bacteria, all of which can contribute to the health of bacteria in the intestines.
You can make a batch of sea moss gel yourself or buy a ready-to-use supplement at your local health food store or online. Even in supplement form, the nutritional content and thus the potential benefits of sea moss can vary. Adding powdered sea moss to soups or stews can have a thickening effect similar to that of using it in gel form. Sea moss also contains a significant amount of magnesium, a mineral essential for muscle contraction and relaxation.
However, current research on sea moss has limitations and scientists still need more evidence to support any health claims. Sea moss has a long history as a fertility treatment for all genders, but there's no real research to support any of this. If people have an existing thyroid problem, they should check with their healthcare provider before taking it because of the iodine content in sea moss. Some anecdotally claim that taking sea moss regularly improves the appearance of your skin and hair.
More human research would help explore the possible neuroprotective effects of sea moss on humans. There's some scientific evidence that supports the use of sea moss for weight loss, but it's not right for everyone.
