Only what you need, nothing you don’t.

Beta-alanine is a non-essential amino acid that defends against the buildup of hydrogen ions and acts at the cellular level to keep the pH within the muscle from getting too acidic. This means it prevents muscle fatigue from occurring too early while also encouraging muscle endurance. Some may experience skin tingling which is a side effect called “paresthesia”. This is completely normal and non-harmful.

Amino acids are the building blocks of protein (which of course is necessary for your body to rebuild and grow new muscle). There are 20 total and the body can only make 11 of them. Of the 9 remaining essential amino acids, 3 are key and make up BCAAs (leucine, isoleucine and valine). Research has shown that BCAAs may reduce fatigue during exercise, reduce muscle soreness, promote muscle building, and also provide an additional source of energy during a prolonged workout. In addition, BCAAs compete with tryptophan (another amino acid) for entry into the brain and conversion to serotonin. As serotonin levels rise they can make you feel fatigued. BCAAs reduce the amount of tryptophan that gets through the blood-brain barrier, therefore reducing the amount of serotonin produced.

Caffeine is a natural stimulant that promotes focus and energy. It has been shown to delay mental fatigue, and also decrease the perception of muscle fatigue. Caffeine is rapidly absorbed in the bloodstream and is shown to improve performance during endurance, power, and resistance exercise.
