What we think

Beta Alanine is our interval and sprint training partner (amino acid) of choice. During intense exercise when lactic acid builds in the muscles, Beta Alanine counters this acid by aiding in the production of carnosine, which neutralizes pH in the muscles.

Carnosine is naturally lower in women, vegetarians and declines with age. Beta Alanine increases muscle capacity and allows you to push yourself to the next level. If you are training hard and looking for incremental ways to get ahead, this is the supplement for you!

It is an especially powerful tool for anaerobic efforts lasting 1-4 minutes or aerobic exercise lasting longer than 4 minutes. 



Take 1-2 tablets once or twice daily or as recommended by your performance specialist.

Excellent product

I have been taking beta alanine on and off for a few years now to support my cycling. It is one of the 5 supplements that have been clinically proven to enhance one’s fitness. I find this formulation particularly good, easy to take, and effective in helping me maintain higher endurance levels especially during hard efforts.

Great product!

Great product. Helps extremely well with my workouts and pushing through. I have been able to do two WODS in a row. The tingles are weird but works for me

Laura L.

Great product. Gives you energy. It does have a bit if tingling effect though but it is normal.

I've been taking Beta Alanine supplements for some time, maybe 5 years now. This one doesn't give me the tingles, maybe I'm just immune to it now. But the effects are superior and its very clean product. I can go a lot longer during my runs or bike rides when compared to not having taken it beforehand. Highly recommended.
