🧪 Formulation Notes

Double Potency 5-HTP Extra is a comprehensive formula designed to support mood and relaxation. Central to this formulation is 5-Hydroxytryptophan (5-HTP), a naturally occurring amino acid that is the immediate precursor of Serotonin. This plant derived compound sourced from the Griffonia simplicifolia, a climbing shrub native to West and Central Africa, helps the body to naturally produce this hormone, helping you attain an improved state of well-being. To complement the benefits of 5-HTP , this product also features L-Theanine that helps to increase alpha brain waves thereby supporting relaxation of the mind and body. This product also includes other botanicals such as Holy Basil and Damiana that have been used in traditional mood formulas and are known for their adaptogenic properties.

This product can be taken daily to help support mood and relaxation, and in doing so, helps promote a more balanced state of mind. What makes us different: Liquid Soft-Gels - The nutrients in these easy-to-swallow liquid soft-gels are released fast. Other forms of delivery can contain binders and fillers that may cause stomach upset and offer no traditional value. Advanced Liquid Soft-Gels provide an optimum delivery system. Quality assurance - Irwin Naturals is committed to providing the highest quality products for your health. We employ compliance testing to ensure purity and potency. Patented BioPerine - Our special BioPerine Complex enhances the bioavailability, absorption and potency of many nutrients.
