Fight Fatigue and Train Harder and Longer!

To meet the energy demands of hard, intense workouts, the body breaks down glucose and glycogen. During this process, hydrogen ions (H+) are manufactured in the muscles. The accumulation of H+ results in more acidity in the muscles and increases fatigue. Our Threshold formula is loaded with Beta-Alanine, Histidine, and Phosphates and is designed to enhance your intramuscular buffering system which means you can work out harder and for longer periods of time.

Beta- Alanine has been around for over 100 years even though it’s a recent addition to the supplement world. It’s also called 3-aminopropanoic acid, it’s a non-essential amino acid and is the only naturally occurring beta-amino acid. It should not be mistaken for the amino acid alanine and is not used in the manufacture of proteins - therefore beta-alanine is classified as a non-proteinogenic amio acid.

The best sources of the natural dietary supplement beta-alanine can be acquired by consuming beta-alanine containing dipeptides: carnosine, anserine and balenine, as opposed to direct beta-alanine consumption. These dipeptides are found in high protein foods like beef, chicken, pork and fish.
