Chlorella (Chlorella regularis) whole plant extract

Chlorella species are unicellular microalga that are rich in vitamins, minerals and amino acids. Chlorella supplements have been popular in Asia, particularly Japan, since the 1950s. Chlorella sp. have also been of great interest to aquatic engineers because of their ability to concentrate and thus remove toxins, including heavy metals, from water1. It is estimated that more than 10 million people worldwide take chlorella supplements2. Animal studies indicate that intake of large amounts of Chlorella regularisĀ  can positively impact blood lipids3,4. In a small double-blind, placebo-controlled trial of adults with mildly elevated blood cholesterol levels, intake of 5 g/day Chlorella for 4 weeks significantly improved total cholesterol, triglycerides and other blood lipids 5.
