I found that my needs differ greatly from the traditional body building-oriented powders and the happy vegan ones, so I could use one, but I still needed to supplement the ones I'm shortest of.@Learner1 thanks very much. I am unsure at this point what kind of balance of amino acids I need.
@godlovesatrier I'm not sure why whey isolate doesn't agree with me anymore. It did at one time but last time I bought the stuff that used to work well and the nausea came. I gave it away.
