Oral administration of probiotic bacteria (specifically Lactobacillus and Bifidobacterium strains) significantly reduces serum cholesterol levels in humans and animals.

To lower cholesterol using probiotics, you must choose specific strains known for Bile Salt Hydrolase (BSH) activity, such as Lactobacillus plantarum, L. acidophilus, or Bifidobacterium species. Generic probiotics may not work. Consistent daily consumption of these specific strains (often found in fermented foods or supplements) has been shown to reduce cholesterol by 22-33% in studies, primarily by helping your body excrete bile acids, forcing your liver to use up stored cholesterol to make more.

GoodSupportsHIGH confidence
Oral administration of probiotics has been shown to significantly reduce cholesterol levels by as much as 22 to 33% [7, 23] or prevent elevated cholesterol levels in mice fed a fat-enriched diet [84].

Why this rating

The paper reviews multiple animal and human clinical trials showing consistent trends, though it acknowledges that exact mechanisms are not fully known and results vary by strain.
