It’s easier to sleep at night and I feel more stable mood wise throughout the day. It’s only been a couple of weeks but I can already see the effects! I love this brand in general for all my supplements bc they are pure and third party tested. I don’t mind a capsule so that’s no issue for me but they are on the bigger side. Review: Very helpful --find the right dose for you - This has helped me a lot. Tryptophan is a precursor for both melatonin and serotonin. Is being studied and should be studied more for anxiety depression especially postpartum. PSA: find your right dose! I started out taking one capsule twice a day just to get a feel. When I took two capsules several times a day (thinking it would help me sleep) I think I had excess serotonin which felt like kind of like too much cortisol, increased anxiety. So this stuff is good but find your balance with it to benefit. ## 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 we leave out matters, too; Pure Encapsulations products are FREE FROM common allergens, artificial or unnecessary ingredients, and GMOs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07H8N948R | | Age Range Description | Adult | | Best Sellers Rank | #62,506 in Health & Household ( See Top 100 in Health & Household ) #1,683 in Amino Acid Nutritional Supplements #2,389 in Blended Vitamin & Mineral Supplements | | Brand | Pure Encapsulations | | Brand Name | Pure Encapsulations | | Color | Red | | Container Type | Bottle | | Customer Reviews | 4.4 out of 5 stars 177 Reviews | | Dosage Form | Capsule | | Flavor | Unflavored | | Item Dimensions | 4.25 x 4.17 x 3.66 inches | | Item Form | Capsule | | Item Highlight | Amino Acid Supplement for Relaxation, Serotonin Support, PMS, and Sleep*, Supports Sleep Quality, Onset, and Duration* | | Item Weight | 0.18 kg | | Item dimensions L x W x H | 4.25 x 4.17 x 3.66 inches | | Manufacturer | Pure Encapsulations | | Manufacturer Part Number | B07H8N948R | | Material Features | Food Safe | | Number of Items | 1 | | Product Benefits | Sleep Support | | Special Ingredients | Amino Acids | | Specific Uses For Product | Laboratory | | Total Servings Per Container | 60 | | Unit Count | 180 Count | ## Product Details - **Age Range (Description):** Adult - **Brand:** Pure Encapsulations - **Flavor:** Unflavored - **Item Form:** Capsule - **Item Weight:** 0.18 kg - **Item dimensions L x W x H:** 4.25 x 4.17 x 3.66 inches - **Package Information:** Bottle - **Product Benefits:** Sleep Support - **Special Ingredients:** Amino Acids - **Unit Count:** 180 Count ## Images ![- L-Tryptophan, 180 Capsules - Image 1](https://m.media-amazon.com/images/I/710FsR3UvjL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the source of the dextrose used for this tryptophane? 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Working for me so far! *by B***. on August 25, 2026* I’m taking this as part of treatment for PMDD and so far I have found it very helpful.
