I am studying nutrition and I can't express enough that people with eating disorders try this! Also anyone unable to eat a rich and varied diet, which is actually most people in the developing world due to convenience foods. It gives low doses of 8 of the 9 essential amino acids you need everyday to function. Tryptophan is excluded as it makes you sleepy and you don't want that in the middle of the morning/day. The "low" dose of each ingredient does cover the minimum intake required of amino acids, more is ideal for optimal functioning, but this basic dose covers what the human body needs to function. I think everybody should try it. It has increased my energy slightly, increased my focus and I feel a little calmer. Not a panacea by any means, but a very useful ...

The package was delivered fast and packed properly.Quality ingredient and just the right size. One of its benefits is that its a great additional protein supplement for muscle training… composition is perfect as well… designed to fit the diet.Lastly, it tastes good.Truly, iHerb is the go-to shop for all natural health and wellness products. Really love this store!
Finally got a chance to try this after it was frequently out of stock. I'm very happy with this product quality, its also hard to find amino acid blends for a good price. You may notice that the amino acid dosages are on the lower side but I like that it gives me better control over dosage and reassures me that I am not getting too much (I'm a smaller individual with lower needs as a result). I've not noticed any side effects and I take one a day. I am hoping that this will help with energy levels and diet.

The quality and ingredient is good. The siZe is just adequate. I seldom take protein in my daily life so this one helps me a lot. Besides, the package is very decent too. Amino acid benefit cannot be emphasized more. The composition of the product is very fantastic too. For a balanced diet, this one is definitely a plus. If you have to be training your muscles, it can be a great assistant too. After taking this, i am really with some energy.
