Phenylalanine

Phenylalanine is, or rather was, a hot topic. Some people seem to react rather badly to it, and a lot of heck was raised about it being used in products. Things have calmed down and studies have shown that there is no harm in it for healthy people. In this article we will cover what is phenylalanine and how it helps in bodybuilding

It elevates the mood by stimulating the nerve system, and may be important to staying motivated for whatever reason. It aids memory and together with its derivative, glutamine, is considered a smart-vitamin (though they aren't vitamins).

It increases levels of epinephrine, nor-epinephrine, and dopamine in the anterior pituitary. All three are important neurotransmitters needed for optimum operation of the nerve system. It also helps the absorption of UV rays in sunlight, which in turn gives a higher rate of Vitamin D, a strong body hormone.

Its main metabolite is tyrosine which increases levels of dopamine and nor-epinephrine, as stated above. It's also one of the manufacturers of glutamine, the amino acid that makes up the largest part of the amino acid pool.

Phenylalanine often gets a bad wrap in the press. It is used as a non-carbohydrate sweetener in many soft drinks (combined with aspartic acid, as aspartame) and made headlines recently when some claimed it was hazardous to the brain, and then later it was linked to carcinogenic risk.

Toxic levels of phenylalanine can indeed be lethal, but trust me, so can anything else. If I put a gun to your head and made you drink twenty gallons of purified water, you'd be dead too. And that's water. Imagine what vitamins or minerals could do?

Yet somehow I doubt anyone feels vitamins are an evil poison, put on earth to kill you. Well, neither is phenylalanine. It's an essential amino acid, and most nutritionists will tell you that you are more likely to be deficient than run the risk of overdosing.

Toxic doses exceed 3 to 4 times the amount you would get on average from a diet containing 250-300 grams of protein daily. So that extra diet Coke won't kill you.
