Many sensitive individuals who typically react to nutritional supplements can tolerate Optimox products. Founded in 1978, Optimox brought clinical research to evidence-based nutritional formulas. During the summer months, products may arrive warm. Recommended use: Take one to three tablets daily, or as recommended by a healthcare practitioner. When used in conjunction with jodorale 50 mg tablets, the recommended amount is one tablet of ATP Cofactors for every 50 mg jodorale tablet. The flushing associated with niacin does not occur because this formula utilizes a non-flushing form of niacin. Warning: Urine may turn dark yellow with high levels of riboflavin intake. Since 1978, Optimox has used only the purest raw materials available and has implemented strict quality control procedures in every phase of production, including raw material inspection, manufacturing, packaging, and storage. Optimox fully discloses all ingredients, both active and inactive, on every product label.
