The Rise of Sea Moss: Health Claims and Nutritional Insights

Sea moss, a type of algae closely related to Irish moss, has gained significant attention on social media platforms, particularly TikTok. Influencers often showcase the product, claiming various health benefits such as improved skin conditions and digestive health. The substance, which can be found in jars priced upwards of $35, is marketed as containing over 92 essential nutrients. However, the actual consumption of sea moss can elicit mixed reactions, with some influencers struggling to ingest it while promoting its supposed advantages.

According to Dr. Margaret Murray, a course director at Swinburne University, sea moss and similar algae products are projected to contribute to a growing "algae products market," expected to reach A$5.2 billion (US$3.7 billion) by 2034. While preliminary research suggests that algae may help manage blood sugar levels and support healthy cholesterol, most studies have been conducted on animal models or cell cultures, leading to uncertainty about their effects on human health. Dr. Murray emphasizes that more robust studies are needed to establish effective dosages and frequency of intake for humans.

Both Dr. Murray and Associate Professor Evangeline Mantzioris, an accredited practicing dietitian, caution against relying solely on sea moss and similar products for nutritional benefits. They highlight that while algae are nutrient-dense, the nutrients obtained from these products do not surpass those found in whole foods. Mantzioris warns that sea moss can contain iodine, which may pose risks for individuals with thyroid issues, and it can also accumulate heavy metals from contaminated seawater.

Critics argue that the marketing of sea moss as a "natural" health supplement can be misleading. Dr. Murray points out that "natural" does not equate to "safe" or "beneficial," citing examples of other natural substances that can be harmful. Both experts recommend that individuals consult with accredited dietitians and medical professionals before incorporating sea moss into their diets, especially as a complementary therapy.

While sea moss and chlorella can contribute to overall nutrient intake, experts advise that they should not replace a balanced diet. Mantzioris suggests that these products may be acceptable in normal amounts as part of a healthy diet, particularly for communities that traditionally consume them. However, Dr. Murray warns that adding sea moss to an otherwise poor dietary pattern will not rectify unhealthy eating habits.
