    The Happy Mood Messengers

    5-HTP is found naturally in the Griffonia simplicifolia seed which is a shrub native to West Africa and Central Africa.

    The full name of 5-HTP is 5-Hydroxytryptophan, which is a natural compound that our bodies make from the amino acid, tryptophan.

    5-HTP is a natural precursor to serotonin - a neurotransmitter & chemical messenger in the brain that helps to relay messages from one area to another.

    Research suggests that serotonin may be involved in a number of psychological functions in the brain relating to mood, sleep and relaxation.

    Put Your Best Foot Forward

    Formulated with the purest possible grade of naturally extracted griffonia seed, Puro 5-HTP is our clean & high strength formula that's vegan-friendly and made here in the United Kingdom to GMP standards.

    100% free of synthetic additives, fillers & unnecessary ingredients.

    It's one seriously effective natural supplement.

      I made a herbal change from medication

      As soon as I switched from a mild antidepressant to this highly recommended alternative, I felt SO much more happy and relaxed. We’ll on my way to 1.5 years now and would highly recommend!
