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 brains version of adrenaline. Noradrenaline is the brains 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 acidtyrosine. 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.

Dosage and Use

Place one tablespoon of mix in four to eight ounces of cold water or fruit juice. Stir briskly and drink. Serve over ice for best flavor.
Consume as desired one to four times per day.
For best results drink immediately after awakening, on an empty stomach, or about one hour before a meal or usual snack time.


Do not consume more than 2.6 grams of supplemental phenylalanine per day.
Not for use by children, pregnant or lactating women, persons with the genetic metabolic disorder PKU, psychosis, persons taking prescription MAO (monoamine oxidase) inhibitor drugs, pigmented malignant melanoma cancer patients, those with Wilson's disease, or those who have a violent temper. Not for use by anyone sensitive to any of the ingredients.
Excessive consumption of L-phenylalanine or caffeine may cause insomnia, especially when taken in the late afternoon or evening. If insomnia occurs, reducing the amount consumed by 1/2 will usually correct the problem.
If insomnia is a problem, drink BLAST only once per day for the first week, and twice per day, right after your arise in the morning. During the second week and thereafter, drink it twice per day, upon arising and an hour before lunch.
