An exclusive stabilized, absorbable, patented tablet form of NADH has been marketed as a dietary supplement in the United States since 1995. NADH is a very sensitive substance. It degrades rapidly under the influence of light, humidity. temperature, and other factors. For example, it is degraded by milk sugar, also known as lactose, and of the classical tablet filler agents commonly used in many drugs and nutritional supplements. It took more than five years of extensive research to develop a stabilized, oral, absorbable form of NADH that does not use this type of filling agent. This special formulation is now covered by several worldwide patents and was given the brand name ENADA. To date, hundreds of thousands of consumers have experienced many beneficial effects from this product.
