Why does the L have to be in front of phenylalanine?** A: 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?** A: 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?** A: 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** A: 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. ## Frequently Bought Together - NOW Supplements, L-Phenylalanine 500 mg, Nervous System Support*, Amino Acid, 120 Veg Capsules - NOW Foods Supplements, L-Tyrosine 500 mg, Supports Mental Alertness*, Neurotransmitter Support*, 120 Capsules - NOW Foods Supplements, Taurine 1,000 mg, Double Strength, Nervous System Health*, 100 Veg Capsules --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/255727859-now-supplements-l-phenylalanine-500-mg-nervous-system-support-amino](https://www.desertcart.vn/products/255727859-now-supplements-l-phenylalanine-500-mg-nervous-system-support-amino) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-22*
