Athletes Who Use Essential Amino Energy



“I've always loved amino energy and all the variety of flavors available. For me its been in my stack as my pre workout and mid day energy drink. Since the Cafe series was released, everyday at 3pm I mix up my vanilla latte Essential Amino Energy!! Keeps me going and focused the rest of the day..



“This is my favorite product by far! It's the first thing I go for when I roll out of bed in the morning to get my day started on the way to the gym whether it is to train clients or get my own workout in. This product has become a replacement for coffee.



“Essential AmiN.O. Energy is one of those multi-purpose products I can use in a variety of occasions. I truly enjoy it's multi-purpose use. Whether I need an afternoon pick me up, or am about to train or want to use it during my training to help keep my intensity up with its natural caffeine sources, I can use it for all of that and more. With some many flavors to pick from I definitely have options when I want to try something different. Finally being able to control the intensity of the product is huge plus, particularly if I am training at night and don't want a lot of caffeine in my system but just a light energy pump. Best of all, it's a low calorie product so I can stay lean and help build muscle simultaneously.”



“Isn't this everyone's favorite? Taste, recovery support, and a natural blend of caffeine to keep me satisfied and give me the boost I need. I always reached for an Energy Drink when I needed an extra, my it's Essential Amino Energy.. All while helping my muscles recover, double win!



“These are bar none the best tasting aminos on the market. They give me energy. They are great to sip on during a training session. They are also perfect for me to take to work and drink later in the afternoon for that mid-day lag. The best part is all of those beautiful little aminos are helping support my recovery.
