What is Bio-Trim? Bio-Trim is a combination dietary supplement formulated to assist with effective weight reduction. In contrast with the rapid weight loss achieved via crash dieting (i.e. based on a dramatic reduction in food intake), Bio-Trim is aimed at controlled long-term weight reduction, obtained via the manipulation of specific areas of metabolic biochemistry relevant to weight reduction. Bio-Trim contains four substances, each of which relates to a specific metabolic area as outlined below:- l-carnitine, chromium, coenzyme Q10, and a plant extract from the Malabar tamarind (Garcinia cambogia), an Indian fruit used in curries.
