NOW Supplements, L-Phenylalanine 500 mg, Nervous System Support*, Amino Acid, 120 Veg Capsules

Q: Is there a different between phenylalanine and l-phenylalanine? Why does the L have to be in front of phenylalanine?

Yes. There are two forms of phenylalanine: D-Phenylalanine and L-Phenylalanine. They are mirror forms of each other - identical except one is 'left-handed' (L-) the other 'right-handed' (D-). (This is L/D dichotomy is true for all amino acids). D-Phenylalanine is synthetic and generally used more for reducing pain, while L-Phenylalanine is the naturally occurring form that is more readily converted into dopamine and norepinephrine and used to help with mood, energy and focus.

Q: How does this compare to Naltrrxone?

Reading the reference to Naltrexone, one has nothing to do with the other. L-Phenylalanine is a brain food supplement.

Q: How does this compare to gaba?

I use both for different reasons. I use GABA when I need to settle my mind down. I have anxiety and gabba really helps that. I take L- Phenelaline (2-100mg) with a B6 and that specifically helps the fact that I can’t swallow without food getting stuck. I do that in the morning and evening where as GABA you can take when ever and it seems to work within 20 minutes. I find that the GABA-effects work for about 3-4 hours then I may need to take another one (750mg).

Q: Is this product equivalent of Phentermine

We do not have any information on pharmaceuticals. L-Phenylalanine is an essential amino acid that is necessary for the synthesis of proteins. Because L-Phenylalanine can be readily converted into the amino acid tyrosine, which forms part of the structure of the neurotransmittters dopamine and norepinephrine, it is important for the maintenance of a healthy nervous system.
