Essential Amino Acids are the building blocks of protein. HumaPro contains the EAA's needed for your body to make proteins. Basically, it's a very low calorie way to get your protein needs met. HumaPro is also very easy to digest since it's already broken down. If you get a bloated full feeling from shakes you will not get this from HumaPro at all.
HumaPro also supresses appetite a bit. I love using it when dieting because the mixes feel like I am cheating on my diet and it gives me a satisfied feeling after the drink. I also get a boost of energy from it.
Lastly, the flavors are outstanding. I absolutely love the sour grape HumaPro. Not sure if you have ever used EAA's or BCAA's before but most taste bitter or the flavors suck. HumaPro and Chain'D out are the best tasting BCAA and EAA drinks I have ever used period.
