4 Reasons to Love Our 5-HTP

Support your body’s natural serotonin production with Pureclinica 5-HTP—a carefully formulated supplement designed to complement your daily wellbeing and evening routine.

1. A direct precursor to serotonin

5-HTP is a naturally occurring amino acid that the body converts into serotonin, a neurotransmitter involved in mood, appetite and sleep. Each tablet provides 100 mg of high-quality 5-HTP to help support your body’s natural processes.

2. Enhanced absorption support

Every tablet contains 5 mg of black pepper extract, included to help support the absorption and utilisation of 5-HTP. This helps you get more from every carefully measured dose.

3. Added vitamins C and B6

We’ve enhanced our formula with vitamins C and B6. Vitamin B6 contributes to the normal functioning of the nervous system and helps support the body’s natural production of neurotransmitters, including serotonin.

4. Exceptional value in every bottle

Each bottle contains 90 tablets—providing up to three months’ supply when taken as directed. That means a simple, convenient and cost-effective way to support your daily routine.

As with every Pureclinica product, our 5-HTP is manufactured to exacting standards and rigorously tested throughout production, with additional third-party testing of the finished product for quality, purity and consistency.

No difference

Didn’t notice any difference at all after nearly a month. Sleep was the same, mood the same. Bit dissapointed considering the claims. Won’t be buying again.

Works ok

I think it’s helped my sleep a little bit but nothing dramatic. Tablets are small and the bottle lasts a long time which is good. Might try something stronger next time or just stick with it for a bit longer to see if it improves.

Great value and works

Took a while to notice anything (about 10–12 days) but once it kicked in my sleep was deeper and I felt less anxious in the evenings. Good quality and the three-month supply is practical. No complaints.

Simple

Simple, effective and well priced. I’ve tried a few 5-HTP products and this one is noticeably working, where before it was hit and miss.
