Product Detail & Benefits


Endurance Amino is ideal to use after all workouts and races, and really shines (and is the perfect complement to Anti-Fatigue Caps) when taken hourly during training sessions and races that extend beyond two hours. Endurance Amino gives you a wide range of powerful amino acid benefits, without you having to break the bank.

Endurance Amino compares extremely well to high priced amino acid tablets on the market, at a fraction of the cost. The foundation of Endurance Amino is the three Branched Chain Amino Acids, or BCAA (l-leucine, l-isoleucine, l-valine), supplementation of which helps delay exercise-induced or central nervous system-induced fatigue, improve immune system reaction, and enhance recovery. Another amino acid, l-alanine, is included in the Endurance Amino formula. The liver can convert l-alanine into glucose as needed, which the bloodstream transports to the muscles for energy. Additionally, l-alanine aids in the synthesis of pantothenic acid (Vitamin B5), which is also needed for protein, fat, and carbohydrate metabolism.

Last, but certainly not least, Endurance Amino contains glutathione, a tripeptide consisting of the amino acids glutamic acid, cysteine, and glycine. Glutathione is one of the three endogenous antioxidants the body maintains to control excess exposure to free radicals produced during exercise as well as from exposure via the environment. With an Oxygen Radical Absorbency Capacity (ORAC) score/rating estimated to be an astounding 12,000+, glutathione is undoubtedly a potent antioxidant, arguably the most important one in existence.

Rated 5 out of 5 by from Positive results Started using this product to see if it would help with the recovery, and mostly the cramping. So without changing my Tri training routine which has been increasing the distance and activity level. Definitely could feel the improvement- the fatigue level and cramping has is faster to recover and under control specially during the activity and stopped the cramps completely happening in the evenings during sleep. Very satisfied.

Rated 5 out of 5 by from Great Product! I have been using this product along with the Anti-fatigue Caps for a couple of years now. Generally, I pop them an hour prior to going for a bike ride and every hour during. The combination works really well for me. I really push myself when I ride because I don't eride as often as l should. Work seams to always get in the way but when I do ride I feel less fatigued and my legs do not feel the burning sensation as quickly as they would if I hadn't. I find that I can ride harder longer and my recovery time is quicker. These products work as advertised for me and it gives me pleasure out performing cyclist 10 to 20 years younger. Nothing like dropping a 20 year old on a long asent. Hammer products work for me and I gladly promote.

Rated 5 out of 5 by from Loved Endurance Amino When used in combination with Anti-Fatigue Caps, Endurance Amino took me to a whole new level. For the first time I am able to push up a hill at almost 20 mph when in the past I had seen myself crash at 17 mph. This is a great product Hammer!

Rated 5 out of 5 by from magic in a capsule My recovery after long rides/runs was good and I was able to function, even so to be able to do back to back long training days, but muscle fatigue had me so sore that to the touch I felt like my muscles were bruised. I started using the Endurance Amino and IMMEDIATELY felt a difference on the ride/run AND after. I noticed that my recovery is twice as strong, and the next day, i function normally vs looking like a toddler taking it's first steps :) This supplement is a hands down MUST HAVE

Rated 5 out of 5 by from Endurance Amino I realize Hammer Nutrition is mainly for endurance athletes but as a former endurance bike rider, I've been felled by a genetic lung disease. I'm not the performer any longer but I want to live as healthy a life as possible. This product along with Chromemate and Phytolean have proven to be a vital part of my dealing with my disease. I don't experience the out of breath situations I do without it. I am thankful this product is available even for non-athletes.

Rated 5 out of 5 by from A must have! I love Endurance Amino and use it at every event over 2 hours. It is a must-have for me to provide me with the amino acids that my body needs- especially when eating enough protein becomes a challenge (ie. hot days for me). I always have this product on me- I take 2 caps at the beginning of each hour (I am about 125 lbs). Thanks Hammer for making great products for athletes!
