Arbitrarily adding vitamins to drinks and foods is increasing our risk of overdose, adverse side-effects and toxic damage. Drug store (pharmacy etc.) advertising piles of vitamins can be very dangerous to your health. The great thing for them is: the more we take of excessive additives, the more feel bad, the more we think that more additives will help us, the more we buy. Whole foods with minimal processing is best. Avoid added sugar, avoid artificial sweeteners.
