Vitamins: A good multivitamin is a good idea. It's like an insurance policy for when we don't eat right, don't sleep well, etc. Get some guidance because the popular brands are typically very week and not helpful. The dose (read label and check that half or more of the ingredients are several 100 per cent above RDA. Dose more important than a long list. Avoid cod liver oil over long term.
