Research indicates that l-tryptophan supplementation may support restful sleep. In a double-blind, placebo-controlled study, l-tryptophan supported healthy processing and promoted positive outlook in women. In a separate study, it lessened occasional irritability during the menstrual cycle. l-Tryptophan also supports healthy sleep quality, onset and duration. Additional research suggests that tryptophan may promote relaxation and help control occasional cravings. Vitamin B6 provides enhanced support as an important cofactor involved in the metabolism of l-tryptophan. ## Features - Restful Sleep: Supports sleep quality, onset and duration.* - Relaxation Support: Additional research suggests that tryptophan may promote relaxation and help control occasional cravings.* - Pure Quality: Our supplements are made with only premium ingredients sourced from trusted suppliers and guided by our nutritional experts, then carefully manufactured and tested to verify their potency and purity. - Pure Difference: What makes us different isn't just our process or what goes into our supplements -- what we leave out matters, too.

Is any part of it sourced or manufctured outside the US?** A: There is no dextrin in the Pure Encapsulations L-Tryptophan. The l-tryptophan is sourced from the USA and the pyridoxal 5’ phosphate is sourced from China. As with all raw materials, each batch of ingredients received by Pure Encapsulations is tested upon reception for identity, potency (if applicable) and contaminants, which can include heavy metals, residual solvents, allergens, pesticide residues and others depending on ingredient and level of risk. The raw materials are blended and encapsulated in the USA. **Q: what mg?** A: Pure Encapsulations - L-Tryptophan contains 6.7 mg of Vitamin B6 and 1000 mg of TryptoPure per 2 capsules. **Q: is this made from GMO corn?** A: All Pure Encapsulations ingredients, including those derived from corn, are GMO-free. **Q: Is this made by fermentation?** A: L-Tryptophan is derived from corn dextrose fermentation. The corn dextrose fermentation process starts with isolating dextrose from corn (a sugar, so does not contain allergenic corn protein), which is then fed to micro-organisms. The micro-organisms produce these nutrients, and the nutrients are then isolated and purified away from the starting materials. While no corn proteins or sugar remain in the final product (and Pure has tested with negative results), they do not routinely test for corn allergens and therefore they would not be able to guarantee its safety for someone with a corn allergy. It is generally well tolerated by individuals who are corn sensitive. ## Frequently Bought Together - Pure Encapsulations L-Tryptophan | Amino Acid Supplement for Relaxation, Serotonin Support, PMS, and Sleep* | 180 Capsules - Pure Encapsulations Magnesium (Glycinate) - Supplement to Support Stress Relief, Sleep, Heart Health, Nerves, Muscles, and Metabolism* - with Magnesium Glycinate - 180 Capsules - Pure Encapsulations GABA - Supplement to Support Relaxation & Moderation of Occasional Stress - with Premium GABA Amino Acids - 120 Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/428704243-l-tryptophan-amino-acid-supplement-for-relaxation-serotonin-support-pms](https://www.desertcart.tn/products/428704243-l-tryptophan-amino-acid-supplement-for-relaxation-serotonin-support-pms) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-03*
