RU-21 dietary supplement

Question

I was wondering if you could tell me if you are familiar with the RU-21 dietary supplement, and whether it would require kosher certification. RU-21 is "an all-natural supplement that has been clinically proven to regulate alcohol metabolism in order to prevent alcohol-related damage to the liver and keep you from getting hung over." As far as I can tell from the package, it contains Vitamin C, Succinic Acid, Fumaric Acid, L-Glutamine and Glucose (Dextrose). Some more information about the product from the company's website: "When alcohol is consumed, it enters cells and is broken down into acetaldehyde. Acetaldehyde is an extremely toxic compound believed to be responsible for both, most alcohol-related diseases and the addictive process itself. The reaction is as follows: CH3CH2OH+NAD+® CH3CHO+NADN+H+ (1) Then an enzyme called aldehyde dehydrogenase 2 (ALDH2) converts the acetaldehyde into acetic acid, which is non-toxic and can be readily used by the body to provide energy, eventually breaking down into water and carbon dioxide. However, the body is only able to metabolize a certain amount of acetaldehyde within a certain period of time regardless of how much alcohol is being consumed. Consequently, alcohol consumption often results in excess acetaldehyde entering blood stream and causing severe damage to the vital organs and functions of the body." Please advise me if I should be concerned about this product having any non-kosher ingredients, as I was interested in trying it on Purim. Thank you.
