I was looking for a clean & third party lab tested L-Leucine supplement. NutraBio L-Leucine is additives and artificial color free. The capsules go down easy with a taste. I'm that this company produces high quality supplements. Since this supplement is in capsule form, there are no texture or mixability concerns. I am willing to pay more to receive a third party tested, high quality, clean supplement. I have not experienced any adverse side effects while using this product. If you are one who places a high value on quality & safety, this supplement fits the bill.

This may be the single most effective supplement for natural muscle gains! And it's inexpensive! Leucine should be getting more attention from fitness enthusiasts!

I'm using this on the advice of a fellow athlete who swears it increases metabolism of proteins into usable muscle recovery. I dunno. I don't think it's hurting me, so I'll just keep taking it. No bad side effects, no taste or aftertaste. You decide.
