CN2 from LCN is a food supplement consisting of R-lipoic acid, N-Acetylcysteine, vitamin C (1), calcium, magnesium citrate, thiamine (Vit. B1) (2), riboflavin-5-phosphate (Vit. B2) (3), pyridoxal-5-phosphate (Vit. B6) (4), cyanocobalamin (Vit. B12) (5) and NADH (Vit. B3). The allegations presented have been evaluated by the EFSA (European Food Safety Authority) and authorized by the European Commission. R-lipoic acid is the natural, non-synthetic form of lipoic acid and is a basic nutrient that aids in the metabolic processes of obtaining energy. N-acetylcysteine, a sulfur substance that incorporates the amino acid cysteine in its structure and provides a favorable framework for respiratory comfort. NADH (reduced nicotinamide adenine dinucleotide), is the coenzymatic form of vitamin B3 and acts in a multitude of metabolic reactions such as those for obtaining energy. In certain cases there may be an increased need for these nutrients due to toxins, radiation, physical wear, respiratory problems, overweight, stress ... and also due to alterations that hinder their transformation into the active forms, which are those that act on the body. CN Base and CN2 incorporate the authorized forms of nutrients with the highest absorption and activity in the body. In addition, it contains the most frequently deficient nutrients in the correct proportion so that the transporters are not saturated and the ingested nutrients are lost. CN2 provides more active forms such as vitamin B2 which provides riboflavin-5-phosphate instead of riboflavin. Vitamin B6 that provides pyridoxal-5-phosphate instead of pyridoxine. NADH, a coenzymatic form of vitamin B3 instead of niacin. lipoic acid which provides R-lipoic acid instead of lipoic or alpha lipoic acid. It is recommended to take before breakfast or the dose recommended by the professional.
