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

I've been taking 100 mg phenylalanine + 100 mg tyrosine twice daily to help balance my neurotransmitter levels and it's helped me feel much more alert during the day.
Take 500mg/1 gram on an empty stomach 30 minutes before a meal and you'll feel full with very little food. The effect lasts several hours. It greatly reduces food cravings of any sort and it's therefore a huge help for weight loss. No negative side effects. On the contrary I noticed a positive effect on mood. I chose the powder because it's pure without any fillers,but unfortunately it's not water soluble. I solved the problem by putting the powder into capsules.
