Product Description

Well-Researched Benefits5-HTP increases serotonin levels, which promotes restful sleep, helps manage stress, and decreases sugar cravings.* | Greater Absorption5-HTP is well absorbed by the body and easily crosses the blood-brain barrier where it can help balance chemicals in the brain.* And 5-HTP can be taken with meals without reducing its effectiveness. | Unique FormulaTo further facilitate serotonin production, Thorne's 5-HTP formula contains pyridoxal 5'-phosphate, the bioactive form of vitamin B6 and the necessary cofactor for the conversion of 5-HTP to serotonin. | Trusted ManufacturerFor more than 30 years, Thorne has been trusted by health-care practitioners who prescribe our products to their patients.

When the highest standards have been met, Thorne creates higher ones.
Sourcing Exceptional IngredientsWe develop better standards for higher quality ingredients. Thorne cares deeply about where our ingredients come from. We partner only with suppliers whose practices emphasize quality, science, and responsibility. Better ingredients means better potency, absorption, and digestibility - and ultimately better health. | Manufacturing the Right WayWe manufacture our own products to ensure full supply chain transparency. For more than 30 years, we have invested in clean manufacturing practices. We refuse to use ingredients that can inhibit absorption. We perform our final production in the United States. Our Charleston, South Carolina, manufacturing facility is annually certified by GMP and certified by NSF International yearly, a well-recognized independent third-party certification organization. | Four Rounds of TestingWe run four rounds of testing for each of our products. We have invested in two state-of-the-art in-house laboratories that allow us to conduct four rounds of testing, while most competitors test only one or two times. We test our raw materials, in-process batches, finish products, and product stability for each product. | Thinking SustainablyWe're thinking sustainably to protect our environment. We believe the environment should never be compromised for the sake of business gain. At Thorne, we believe that doing our part to protect the environment and its most valuable resources goes hand in hand with our product quality standards. |
