Pure Encapsulations CoQ10 is produced from fermentation and is bio-identical to the CoQ10 produced within the body. Fermented CoQ10 does not contain the impurities that synthetically processed CoQ10 might. CoQ10 is a vitamin-like substance found within every cell in the human body and is especially important in the mitochondria. Pure Encapsulations manufactures hypoallergenic, research-based dietary supplements designed to deliver predictable results. Our supplements are sourced and manufactured to avoid artificial colours, flavours, dyes, sweeteners, magnesium stearate or contaminants.
