Both Dr. Pricilla Slagle and Dr. David Gersten (google them) say to take enteric coated p-5'-p with aminos. The enteric coating ensures delivery bypassing the liver conversion of regular B6 to p-5'-p. P-5'-p is the co-enzymatic form of B6. Vitamin C also is advised to take b/c it has an effect on amino conversion to neurotransmitters. In summary take: 1. Vitamin C, not ascorbic acid but a whole food form, Megafood brand or Garden of Life both make a whole food form of Vitamin C. 2. Enteric coated p-5'-p, Solgar brand is a good one. 3. Whole food B-Complex so you don't encounter any imbalances of the Bs taking only p-5'-p. Megafood brand is my favorite. They have a good balanced one. Also take L-Tyrosine too so you don't deplete your dopamine or norepinephrine levels just taking 5-HTP. And finally, take a whey protein powder for balancing your aminos. Make sure it's whey concentrate which is less processed than whey isolate. I like Jarrow formulas whey concentrate but if money isn't an issue definitely take Mercola whey or Premier Research Labs whey. Most whey is in isolated form and contains many contaminants.... heavy metals, antibiotics, growth hormones, etc... Dr. Carolyn Dean has a fantastic whey concentrate powder called ReStructure which isn't unfortunately sold on amazon. Just google it. It's actually a meal replacement which will save you on food costs. Good luck. **Q: Can anyone tell me how this compares to Vitamin World's 5-htp?** A: Dr. Slagel in her book, The Way Up From Down, and on her website by the same name, recommends Now Foods brand 5-HTP and L-Tyrosine for mood disorders. She is a re-known integrative psychiatrist w/45 years of clinical experience using nutrient therapy so anything she recommends is legit. You want to take a co-enzymated B-complex and a good multi while using 5-HTP along with Now Foods L-Tyrosine for neurotransmitter balance of serotonin and norepinephrine/dopamine. Using just 5 alone can deplete your dopamine/norep levels, vise versa. **Q: What is the difference between the 2 120 bottles?** A: I ordered two the same (I take 2 each night before bed), but always like to have it on hand. The supplement does come in different strengths (50 mg, 100 mg,?etc.). I get the 100 mg formula. Hope that answers your question. **Q: Is this a time-released formula?** A: No. I feel sleepy about 45min to 1 hr after taking it but you can push through that feeling if you don't want to sleep. ## Frequently Bought Together - NOW Foods Supplements, 5-HTP (5-hydroxytryptophan) 100 mg, Neurotransmitter Support*, 120 Veg Capsules - NOW Foods Supplements, L-Tyrosine 500 mg, Supports Mental Alertness*, Neurotransmitter Support*, 120 Capsules - NOW Foods Supplements, GABA (Gamma-Aminobutyric Acid) 750mg, Neurotransmitter Support*, 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.ph/products/1978928-now-supplements-5-htp-5-hydroxytryptophan-100-mg-neurotransmitter-support](https://www.desertcart.ph/products/1978928-now-supplements-5-htp-5-hydroxytryptophan-100-mg-neurotransmitter-support) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-08-30*
