Green Algae Lowers Cholesterol

September is designated National Cholesterol Education Month, and in recognition of this today’s post will review a study of the effects of cholrella on lipid parameters.

Chlorella is a single cell green algae, which is spherically shaped. Research began on chlorella as a potential food source in the late 1940s. Most of the original studies on this particular algae were conducted in labs, and when studies began to be performed in the field chlorella was not found to be quite as easy to propagate as previously thought.

A research group from the Republic of Korea performed a double-blind, random-controlled trial to examine the effects of daily chlorella supplements on serum lipid parameters. After an initial screening and two week lead in phase 68 subjects were randomized into either the chlorella group or the placebo group. The subjects were advised to maintain their usual diet and activity levels. The chlorella group took 4 tablets after each meal, a total of 12 each day, equivalent to about 5 grams of chlorella each day. This continued for four weeks. Food diaries were completed at the beginning and end of the study.

The results of the study showed significant reductions from baseline in non-HDL-C (2.6% reduction), total cholesterol (1.6% reduction), and triglycerides (10.3% reduction).

Some folks develop gastrointestinal problems such as nausea with chlorella, but in this particular study no one withdrew due to adverse side effects. Supplementation might be a way to lower cholesterol in those with mildly elevated cholesterol.
