Product education

5-HTP 100mg: Natural Support for Mood, Sleep, and Appetite*

5-HTP by SFI Health provides a natural intermediate used by the body to synthesize serotonin, a vital neurotransmitter. Serotonin is deeply involved in the regulation of brain activity responsible for controlling emotion, appetite, and healthy sleep/wake cycles. Derived from the Griffonia simplicifolia plant, this supplement offers a safe and direct way to support healthy serotonin and melatonin levels, allowing your body to self-regulate these crucial neurohormones for balanced cognitive health.*

How It Works: The Direct Precursor to Serotonin

This formula provides 100 mg of 5-Hydroxytryptophan to directly support the body’s production of essential neurotransmitters.*

Regulating Emotion & Sleep Cycles
As a direct metabolic precursor, 5-HTP easily crosses the blood-brain barrier where the body can readily convert it into serotonin. Healthy serotonin levels are essential for maintaining a positive mood, managing appetite, and facilitating the production of melatonin, the hormone responsible for regulating sleep.

A Safe, Plant-Based Source
Unlike L-tryptophan, which has to go through an extra conversion step, 5-HTP provides a more direct pathway to serotonin synthesis. Sourced naturally from the seeds of the Griffonia simplicifolia plant, this formula offers a clean, reliable, and effective approach to supporting your overall wellbeing.*

  • Supports healthy mood, sleep, and appetite*
  • Acts as a direct precursor in the natural synthesis of serotonin
  • A safe alternative to L-tryptophan that supports serotonin and melatonin levels*
  • Naturally derived from the Griffonia simplicifolia plant
  • A hypoallergenic formula free of most common allergens
