Bottom line

Read Off Label grades Chlorella as C (4.7/10) based on weak evidence, low-med benefit magnitude, and a low-med-risk safety profile.

Morita 1999 Japanese breast-milk study is the cornerstone of 'chlorella clears toxins' claims.

Typical use: 2-3 g/day PO divided with meals — OTC.

What this is

Morita 1999 Japanese breast-milk study is the cornerstone of 'chlorella clears toxins' claims. Cell wall breakage (CGF vs standard) affects bioavailability. Cheap products can be contaminated — look for Japanese or Korean sources with heavy metal testing. Vitamin K content matters for warfarin users.

Mechanism

Green alga high in chlorophyll; proposed binding of dioxins, methylmercury, other lipophilic toxins in the GI tract; interrupts enterohepatic circulation of bile-excreted contaminants

Dose & route

2-3 g/day PO divided with meals
