Protein intake is somewhat controversial. Some say more, some say the RDA is all that we need.
The fact is, most (meat eating) Americans get MORE than they need on a daily basis. For example, the RDA for energy for a 19-24 year old male who is 72kg is about 2,900 kcal/day. If 12% of that is protein, then 348 kcal are taken in as protein (12% of 2,400 kcal). At 4 kcal/g, this person would consume approx. 87g of protein per day, representing 1.2g x kg-1 x d-1 (87 g/70 kg), or 50% more than the RDA standard.
My main point in my initial post was that protein supplements as well as amino supplements are not beneficial, as no controlled studies have demonstrated taking anything over the RDA for protein is necessary, or shown any significant strength gains in double blind studies for amino acids.
Hi! *waves* I'm new as you can tell. I'm reading a book I checked out from the local library called "From A to Zinc" or something of the sort by Dominick Bosco. It's a little dull, but if you want to learn more about RDA this is the book for you. Throughout every vitamin and mineral he goes through, he repeats that RDA is a RECOMMENDED daily allowance. It varies from person to person, and it shows studies that people taking the RDA of many vitamins and minerals have had deficiencies, and some have even had too much. It also shows you the vitamins and minerals that you CANNOT EVER overdose on. You could take 100 1,000 mg supplements of certain ones and not get hurt from it; in fact, you'd probably be healthier. Just some insight. If you want to find the book it's in the 613 section I believe.
