When we drink coffee or other quick-release caffeine beverages, there is a surge of noradrenaline release in the brain that gives us a burst of energy. The problem is that this sudden release of noradrenaline depletes its precursor, L-phenylalanine, thereby causing the caffeine “letdown” effect so many people experience later in the day. By taking L-phenylalanine and other noradrenaline factors with caffeine, many people are able to achieve sustained energy levels throughout the day. The reason is that the L-phenylalanine induces more noradrenaline to be produced in the brain.1-2*
Blast™ is a high-performance designer food comprised of caffeine, L-phenylalanine (an essential nutrient amino acid), and essential nutrient cofactors. Use Blast™ for a fast start to a long, hard-driving day of work or play. The product includes a flavor system comprised of citric acid, malic acid, fumaric acid (the substances that give many fruits such as apples, oranges, and cherries their tart flavor), natural flavors, and silicon dioxide (mineral dispersant and wetting agent).
L-phenylalanine, along with the other nutrients in Blast™, provides your brain with a system of raw materials it can use to make the essential neurotransmitter noradrenaline, the brain’s version of adrenaline. Noradrenaline is the brain’s natural stimulant, giving you mental energy and get-up-and-go. L-phenylalanine is also converted in the brain to dopamine,1-2 a neurotransmitter involved in memory and reward circuitry, and beta-phenethylamine, a neuromodulator that increases the activating effects of noradrenaline.3-8* The L-form of phenylalanine can be converted in the body to another amino acid—tyrosine. Tyrosine, in turn, can be converted into one of several neurotransmitter molecules (L-dopa, norepinephrine, and epinephrine), each of which have important functions in brain metabolism.
