5HTP | Griffonia simplicifolia extract
Premium 5-HTP Supplement - All Natural Ingredients, No Artificial Fillers or Binders
Experience enhanced mood, restful sleep, and increased energy levels with our premium 5-HTP supplement, crafted from 100% natural ingredients without any artificial fillers, binders, or additives. Sourced from the seeds of Griffonia simplicifolia, our 5-HTP provides a high-quality, bioavailable form of 5-hydroxytryptophan, a precursor to serotonin—a neurotransmitter crucial for mood balance and sleep quality.
Why Choose Our Premium 5-HTP?
- Mood Support: Numerous studies indicate that 5-HTP supplements may aid in boosting serotonin levels, which can help enhance mood and reduce symptoms of stress. Research published in the Journal of Neuropsychiatric Disease and Treatment found that 5-HTP supplementation can support individuals experiencing low mood.
- Improved Sleep: By promoting serotonin production, 5-HTP can aid in the production of melatonin, the "sleep hormone." A study from Sleep Medicine Reviews notes the benefits of 5-HTP in supporting better sleep quality, helping you wake up refreshed and energized.
- Appetite Control and Weight Management: 5-HTP may aid in appetite control by improving satiety and reducing cravings, as highlighted in research from the American Journal of Clinical Nutrition.
- Natural, High-Quality Ingredients: Our 5-HTP supplement is made using natural Griffonia seed extract and is free from any synthetic fillers or binders. This ensures a pure, potent product that supports your wellness goals without unwanted additives.

Fettle is a health store, reimagined.
Built in Holmfirth. Inspired by the wild.
We stock a wide range of curated products - carefully chosen foods, proven supplements, and low-impact home goods—with one aim: to help people feel well, live fully, and tread lightly.
We're guided by four principles:
Roam – move with purpose
Replenish – eat well, choose consciously
Rest – take space to recover
Renew – build resilience, inside and out
We favour quality over quantity, makers over mass production, and brands that back their ethics with action. You’ll find organic staples, therapeutic herbs, and sustainable tools for daily living—all under one roof.
Upstairs, our practitioner room offers tailored support, from nutrition to movement and mental clarity. Downstairs, you’ll find the starting point for your next chapter—whether that’s a new habit, a better meal, or a slower way of being.
Fettle is a basecamp for the everyday explorer.
Come as you are. Leave with what you need.
