L-TYROSINE + Caffeine
Tyrosine is an amino acid that’s involved in the production of neurotransmitters in the brain. In fact, it’s a precursor to norepinephrine, which is an excitatory neurotransmitter that has a major effect on mental focus and energy production. Research shows that tyrosine supplementation can help improve strength and endurance when combined with other compounds such as caffeine.
Beta-alanine has the ability to buffer acidic waste product in muscle during intense exercise. When beta-alanine is used as a supplement, it’s taken up by your muscles, and together with histidine, is resynthesized into carnosine by an enzyme called carnosine synthetase. An increase in intramuscular carnosine levels can increase the buffering capacity of a muscle by up to 20 percent and result in a dramatic delay in muscle fatigue and considerable improvements in strength and endurance. Beta-alanine also increases nitric oxide (NO) by activating the NOS enzyme, which mediates an increase in vasodilation, blood flood and muscle pumps. In a nutshell, Beta-alanine ensures your muscles are primed for maximum performance, growth and recovery!
Although carnitine is well known for its fat-burning properties, it can also improve performance and recovery after intense exercise. Carnitine plays a key role in muscle glycogen metabolism, ATP production, muscle tissue repair and even free radical scavenging. Supplementation with carnitine before exercise can increase muscle glycogen storage and improve ATP production, which improves strength and delays fatigue.
