I think he was talking about supplements, as in something over and above what should already be a hallmark of any person's regiment regardless of age, or that can already be derived from whole food sources. Fish Oil, a Multi, and Protein... these are always understood and therefor redundant; akin to suggesting he drink water.
how u know what he was talking about?it might be redundant for u but not for a bengineer..he said BASIC supplements.. fish oils are as basic as u can get ..also he was looking for help with muilti and proteins above ..there is no hint that he knows anything that is hallmark or staple..
