Chlorella is a tiny, nutrient-dense freshwater algae that has been studied intensively for its ability to bind to heavy metals like mercury, lead, and cadmium and help carry them out of the body. It is one of the most chlorophyll-rich foods on earth, which is central to many of its detox properties. Grown commercially since the 1950s — especially in Japan — it has become one of the world's best-selling algae supplements.
Chlorella's thick, fibrous cell wall acts like a sponge, binding to heavy metals and certain environmental toxins in the gut so they can be excreted rather than reabsorbed. Its high chlorophyll content supports liver function and helps neutralize harmful substances. The unique Chlorella Growth Factor (CGF) — a nucleotide-peptide complex found only in chlorella — appears to support cellular repair and immune regulation.
Broken cell wall tablets or powder are the most bioavailable and most studied forms for detox. Whole-cell tablets are less expensive but deliver fewer active compounds. Powder mixes easily into smoothies. Capsules and tablets are more convenient for daily dosing. Liquid extracts are available but less commonly studied.
Chlorella was first identified by Dutch scientist Martinus Beijerinck in 1890. After World War II, Japan invested heavily in chlorella research as a potential food and detox solution. It has been used in Japanese integrative medicine for over 70 years and is now popular worldwide as a detox and superfood supplement.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Chlorella Detox is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
