lucky me as far as the k/d combo is concerned because that is one of the only ones I take but did so because a genuine deficiency was found by a doctor during a blood check.
speaking of mushrooms, a friend of mine really pushes these mushroom extracts that taste like ass, and he is always asking me how much better I feel from taking them. I lie because I only bought them because I felt bad for my frined's failing business.
I suppose there are a lot of benefits out there of a lot of things. I would be a lot more likely to take the advice or recommendations of someone on here or if it was from a plant than some bottle at GNC or something like that though.
