Review: L-Leucine Supplement Clean Supplement - 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.
