That means you get a boost in short to medium duration high-intensity muscle performance. Think bodybuilding-style training, CrossFit, and HIIT.* Beta-alanine has been shown to increase muscle power output, strength, training volume, exercise performance and peak oxygen uptake (aerobic capacity) when used consistently.* Acetyl-L-Tyrosine Acetyl-L-tyrosine is a more bioavailable form of the amino acid L-tyrosine, which is used by the brain to make dopamine. Dopamine plays a big role in memory, focus, libido, and sense of well-being. Some of acetyl-L-tyrosine's effects include:* Improved mood* Increased positive outlook* Improved memory and learning capacity* Increased energy* Improved concentration* Vitamin B12 (Methylcobalamin) Methylcobalamin is the superior, more biologically active form of vitamin B12. Other forms of B12 must be converted in a two-step process, but methylcobalamin is active immediately upon absorption. Among other benefits, methylcobalamin:* Boosts energy* Supports the nervous system* Helps memory and learning* Promotes a healthy cardiovascular system* Supports brain and nerve function* *These statements have not been evaluated by the Food and Drug Administration.
