Sea Moss: hype or Health Food? Concerns Rise Over Heavy Metals, Iodine Levels in Popular Algae
Berlin – Sea moss, touted by wellness influencers and celebrities as a nutritional powerhouse, is facing increased scrutiny over potential health risks. While available in various forms – dried, gel, powder, and capsules – and often added to smoothies, experts warn of possible digestive issues, immune system burdens, and the presence of concerning levels of heavy metals and iodine.
The red algae has surged in popularity as a supposed superfood, promising a range of benefits. However, a growing body of concern highlights potential downsides, prompting health organizations to issue cautions. This comes as demand for natural health remedies continues to climb, making it crucial to assess the true risks and benefits of trending ingredients like Sea Moss.
Consumer advocacy group Öko-Test has criticized Carrageen, a component of some Sea Moss products, citing potential digestive and immune system impacts, as well as possible allergic reactions. More seriously,testing has revealed the potential for contamination with heavy metals – lead,cadmium,arsenic,and aluminum – which can negatively effect the kidneys,brain,and perhaps increase cancer risk.
Iodine levels are also a notable concern. Often present in excessive amounts, high iodine intake can interfere with thyroid function, posing a particular risk for individuals with pre-existing thyroid conditions like Hashimoto’s disease.
The German Nutrition Society recommends limiting algae consumption to a maximum of one gram per day. The Federal Institute for Risk Assessment stipulates that dietary supplements should contain no more than 100 micrograms of iodine for pregnant women and breastfeeding mothers, and 150 micrograms for the general population. Products should clearly state both iodine content and recommended daily intake.
While Sea Moss can be nutritious, evidence supporting many of its purported benefits remains limited. Experts advise caution, particularly for those with underlying health conditions. Healthy individuals can consume it in moderation, but can also obtain necessary nutrients from lower-risk sources. (DK)
