The market is full of preworkout supplements, making it hard to choose the one that’s right for you. One of the best ways to pick one is to consider individual ingredients that you’ve noticed work particularly well for you. Absent that knowledge, consider seeking out products that contain the following three amino acids.
This amino acid combines with another, histidine, to form the compound carnosine. Research shows that higher levels of carnosine are associated with muscles that are stronger and have better endurance. While you can supplement with carnosine directly, research has shown that supplementing with beta-alanine may be even more effective. Beta-alanine also enhances the effects of creatine, providing two ways to support muscle building.
Arginine is one of the best-known aminos for supporting better workouts. In addition to increasing muscle pumps during workouts, this amino acid encourages delivery of more oxygen and nutrients to working muscles (facilitating growth and recovery) by converting to nitric oxide in the body.
Serious weight trainers know that this amino is beneficial for boosting energy levels before training sessions. In the body, tyrosine converts to crucial brain chemicals and hormones (including epinephrine, norepinephrine, dopamine and thyroid hormones), which then help fuel activity by increasing metabolic rate and breaking down stored body fat to be burned for energy. Tyrosine also enhances muscle strength and helps reduce fatigue.
