It also has a direct effect on our sleep cycles because the brain uses it to make melatonin – a hormone that regulates sleep. • VEGAN & GLUTEN FREE – Our 5 HTP supplement is proudly manufactured in the Uk and contains only high-grade ingredients to ensure they're gut-friendly and suitable for vegans. • PREMIUM QUALITY STANDARDS – Manufactured in the UK whilst adhering to GMP standards.
