Wow. Um, the RDA for vitamin C is 60 mg. Unless he is severely deficient, he does not need 3000mg. Too much vitamin C can be toxic. And despite what many people who post on this website want to believe, RDAs are not crap; they're not numbers that scientist pull out of their asses. RDAs are amounts of nutrients carefully determined to be sufficient for 98% of the population and includes margin of fluctuation. That means that 60mg is not a minimum or a maximum, but part of a range that goes lower or higher than the given amount, but certainly not 50x the amount. That is dangerous.
1.3 mg per day is the RDA for males ages 19-50
11mg per day is the RDA for males ages 14 and older.
35 mg per day is the RDA for males ages 14-50.
No one food can supply all optimum levels of vitamins and minerals, but if you eat a balanced diet, there is absolutely no need to intoxicate yourself with insanely large doses of supplements. To do so is dangerous and a waste of money.
This sort of reasoning sucks. First of all, we are made mostly of water and protein. While it's true that our bodies contain more minerals than vitamins, we still need to make sure that we are comsuming adequate amounts of each. Our bodies use them together in life processes; they are interdependent.
Please don't offer irresponsible advice.
