Chlorella

Chlorella is a freshwater microalga sold as a powder or tablets and marketed as a superfood and adaptogen, with promises of detox, more energy and immune support. There is no convincing evidence that the supplement delivers these effects in healthy people. It also shows no harm at usual doses, but there is little reason to expect the claimed benefits. For genuine support, sleep, a diet with vegetables and greens, and regular physical activity do far more.

Chlorella is actively marketed for «removing mercury from amalgam fillings», «lead detox» and «binding gut toxins». These claims do not withstand scrutiny. The Merritt systematic review (J Med Toxicol 2022) analysed available clinical data on chlorella as a heavy-metal chelator: there are no quality RCTs, epidemiologic studies are small and contradictory, and no data show that chlorella reduces blood or urine mercury in patients after amalgam removal. The American Dental Association and FDA (2020) confirm that amalgam fillings are safe in adults and pregnant women outside risk groups, and no special detox is needed after them. The «heavy-metal removal» concept with chlorella is part of «biological dentistry» (IAOMT), not supported by evidence-based medicine. Real heavy-metal poisoning is treated with registered chelators – dimercaprol, DMSA, EDTA – under toxicology supervision. If chlorella was bought for «post-amalgam detox», discuss with a doctor; the risk of unnecessary intervention outweighs the benefit.
