Supplement Description

What is 5-HTP?

5-HTP is converted in the body into the brain chemical messenger serotonin. Serotonin in the brain acts as a chemical messenger and is influences the majority of the cells in the brain, including sleep, appetite, mood and sexual desire.

5-HTP is derived from West African Griffonia simplicifolia tree, the only natural source available, using a specially developed process that retains as much of the active ingredient as possible. The supplement is then encapsulated in a fully vegetarian cellulose capsule, each providing 100mg of 5-HTP (in amino acid form).

Why buy a 5-HTP supplement?

Serotonin is involved in mood, appetite and impulse control, and has an effect on our state of restfulness.

Unlike cheaper Griffonia Seed powder,our UK-sourced material is 99% pure. This means that it only requires 101mg of Griffonia Seed to make our capsules. Some of the cheaper supplements on the market use inferior 70% material, which is much less pure than ours, so please be aware of what you are buying.

You can also be assured that our 5-HTP is certified to be 'Peak-X' free, and is sourced and manufactured in the UK to GMP quality standards.

Improved super strength vegetarian capsule

As a result of customer feedback we have recently made some improvements to this supplement. It appeared that the tablet-coating could crack and crumble under certain storage conditions, due to moisture absorption, so have changed the format of this supplement from a tablet to a two-piece capsule which has resolved the problem. Please be assured that the active nutrients are exactly the same as before, so if you are a regular customer you will still be buying the same, great supplement, just in capsule form, rather than as a tablet.

Qualité rapidité prix
Service Rating: Fast delivery. Good value. Seem to be genuine products.
Product: I think I had mild depression for a while, byut I didn't want to go straight on to antidepressants without trying other strategies first. It took just a week of taking these supplements, along with a SAD lamp, a mindfulness program, and B-complex vitamins, for me to feel more like myself again. Sleeping better, more motivated, less easily stesssed, more positive in general.
