why it works

A primary contributor to pre-workout fatigue is a weary central nervous system (CNS) that requires more than just energy from food to get you going. Fortunately, AML has discovered a unique blend of compounds that conquers CNS fatigue by reestablishing the required levels of the correct neurotransmitters to restore focus and motivation needed for intense training.

the science

behind the formula

Since reduced dopamine levels within the CNS decrease motivation and performance while inducing fatigue, novel ways to increase dopamine production before your workout should boost exercise performance. The consumption of the dopamine precursor tyrosine was recently shown to provide this benefit in a double-blind study, confirming that tyrosine consumption influences the ability to tolerate prolonged exercise, conceivably by increasing dopamine levels. AML Preworkout combines tyrosine with folic acid, which may further increase dopamine by increasing tetrahydrobiopterin (BH4) levels. As a co-factor for tyrosine hydroxylase, BH4 facilitates the conversion of tyrosine to L-dopa, which is a precursor to dopamine. The tropical plant mucuna pruriens is also found in AML Preworkout. This ingredient is loaded with the dopamine precursor L-dopa, which has been shown to effectively increase diminished dopamine levels in patients with Parkinson’s disease.
