Abstract
The present study evaluated the mutagenic and toxicologic potential of a proprietary greens product sold under the trade names: All Greens®, Enriching GreensÒGreengevity®. This is a plant food concentrate of berry and enriched greens extract. An in vitro bacterial reverse mutation assay, showed no toxic effects in any of the five tester strains used up to the highest dose group evaluated except for a weak mutation effect in tester strain TA 1537 at a concentration of 5,000 µg/plate without metabolic activation. No biologically relevant increases in revertant colony numbers of any of the five tester strains were observed. In a 14-day feeding study of dietary levels of 0, 1.25, 2.5 and 5.0% in rats, there were no adverse clinical, body weight, food consumption or macroscopic changes associated with the administration of this product.
Key words: All greens, toxicology, Ames, 14-day dietary study.
