DAVINCILabs Amino 21 - Supports Brain Function & Muscle Metabolism* - Amino Acid Dietary Supplement with L-Glutamine, L-Lysine HCl, Tyrosine, L-Arginine and More - Gluten-Free - 90 Capsules, 750 mg

Good and effective, pill are not very big so easy to swallow

I started taking Amino 21 years ago when it was precribed by my then chiropractor. I frequently luck energy to do the most basic things, and this product helped a lot. Right now, I'm taking it due to an aminoacic deficiency detected by my Dr. I higly recommend it, but, please, see your Dr first.

Great product but I honestly did not feel a difference. My other supplements have BCCA’s so that could be why. Packaged great and received great

Excellent product for daily nutritional needs from a reputable company. The capsule size is smaller than an ibuprofen liquidcap and easy to swallow but also good quality if you needed to get the contents out.

Naturopath recommended this and it has been helpful

Good product, trust this company.

Gave me a lot of muscle in the few days I took it. But I only took it those few days since I have other protein alternatives. I may come back to this again tho.
