Abstract: The present invention relates to a dietary supplement for the treatment of weakness in metabolic activity containing Pantothenic acid (CoA), its precursors and/or its salts, a process for its production as well as its use. Application areas of the invention are food industry and medicine. The invention is based of the surprising finding that the intake of pantothenic acid, pantothenic acid-CoA and/or its derivatives in a large amount has a beneficial effect on symptoms caused by weakness in metabolic activity. The core point of the invention is that the uptake of a pantothenic acid-CoA equivalent from food is not 10 mg per day, but more than 103 times of this amount to provide the human organism optimally. It was also a surprising finding that the cholinergic Panthenol-CoA uptake reaction from food was taking place within a few minutes. The dietary supplement according to the present invention is a compound for comprising 85-99% Pantothenic acid and/or its salts and other supplements if applicable.
