Product Information


ESSENTIAL AMINO PROTEIN starts with an ultra-high quality, easy-to-digest protein source focused on the essential and branched chain amino acids in the form of easy-to-absorb smaller peptides and free-form amino acids. Typical protein sources and powders can contain difficult-to-digest and absorb proteins, but Essential Amino Protein starts with a highly bioavailable protein source that we fortify with essential and branched chain amino acids. Essential Amino Protein is not just an advanced protein source for athletes, but also provides the most important amino acids for anyone focused on wellness and optimum health. Essential Amino Protein provides an ideal balance of amino acids to support the structure and function of our key organs and tissues, along with the enzymes we rely upon to perform all our body’s biochemical and metabolic activities. It is well established that protein quality more than the quantity determines optimum health and physical performance, which is why Essential Amino Protein focuses on those amino acids that determine protein quality. Essential Amino Protein comes in small easy-to-swallow capsules that contain our highly bioavailable protein/amino acid source, which is also hormone-free, lactose-free and sodium-free.

Healed my adrenal fatigue pain This product is wonderful! I suffered from severe adrenal fatigue for several years and was unable to exercise or exert myself. My husband had ordered Essential Amino Protein for himself to take after his workouts. One day after attempting light exercise, I became extremely exhausted with pain radiating from my adrenal glands (this was a common occurrence). The Essential Amino Protein was sitting on the counter and I saw the pictures on the label of strong, active people working out. At that moment, I realized that my body was not getting the amino acids it needed to heal and repair my body. I immediately got up and took 4 capsules. Within 20 minutes, a miracle adrenal pain disappeared and my exhaustion was significantly less. I was so excited!!! I now take 4 capsules, 4-5 times per day and this has helped my adrenals and body heal and repair, like nothing else ever has (I have taken so many supplements for this issue, so I would be the person to know). I have consistent energy throughout the day and if I ever feel tired or weak, I immediately take this product. I highly recommend!!!!!

Joe Wieder Sent Me Hard to find quality complete amino acid capsules. Based on recommendation from Joe Wieder, starting taking complex amino acid capsule in my early 20s. Thanks to ProCap Labs 40 years later amino acid capsules are still part of my nutrition supplement regime. Excellent individual amino profile.

Lifesaver! My husband is on dialysis and one of the things monitored every 2 weeks is his protein. When he first started dialysis his levels were low. After taking the 4 capsules daily for a month his numbers improved, and his blood tests are consistently very good each time we get a report. I was also glad to read that this is important for critical organs. Thanks Andrew for all the work and research you do. It's wonderful to have products that are not loaded with chemicals and other strange things.

Mouth ulcer relief I have suffered with mouth ulcer sores since my late 20s and nothing made them go away and stay away. I am 61 now so I have suffered a long time. Sometime I had upwards of 20 in my mouth at any one time. I read on the internet about a product that was amino acids and they would clear up mouth ulcers. The product did nothing but then I thought since I took so many of Andrew's products that I would try his Amino Acids and it was a miracle. I have been taking them for about 2 years and the name has changed but the miracle continues. The ones under my tongue were the worse ones. Sometimes now in times of illness or stress I will feel some coming on and I take a little extra and by the morning the soreness is gone. Everyone always asked did I try L-Lysine and I had tried it but I obviously needed a range or Amino Acids because this product works. I don't know what else it may be helping with but the sores are under control. I know there are a lot of people out there who suffer from these sores and I encourage you to try this product because it is answered prayers for me. All of Andrew's products are amazing and I would give them 100 stars if I could.
