Product Overview

Description

  • Dietary Supplement

  • An Essential Amino Acid

L-Phenylalanine, an essential amino acid, is a precursor of the amino acid tyrosine and a whole series of neurotransmitters and hormones. Phenylalanine is first converted to tyrosine, which becomes L-dopa, which converts to norepinephrine, a key neurotransmitter and an adrenal hormone. L-Phenylalanine is also a direct precursor of PEA (phenylethylamine), another important neurotransmitter.

My husband is currently taking this product 3x3 times a day for Parkinson's. It seems to work for him and lets hope he does for a long time.

Thanks for your feedback!

Good quality amino acid supplementation

I purchased this product on behalf of a friend, who had serious health issues and had been prescribed a mix of amino acids to overcome it (Round-up toxicity). She got on well, and felt the amino acids helped her greatly.

Thanks for your feedback!
