How do we compare ?

More than DOUBLE the strength of Major pretend UK Brand Holland & Barrett (them 50mg, us 120.6mg per capsule). We sell in monthly packs so our product blows them out of the park. Plus we now have added our uptake blend to our 5htp so it is x10 times better than what it was.

Nasty Free who sells them Clean like us ?

* Important *

You have all been asking for black pepper (piperine) in your Turmeric so we have gone one better and are adding an ancient Ayurveda uptake blend to most of our products over the next month. Each product will be 9:1 meaning 9 parts herb and 1 part uptake blend (black pepper 10% Piperine, cumin extract, ginger extract 5%). This will improve our products a lot. What will change? The amount of herb/product won't change that much as we have done 10 so far and they are around about the same amounts. We are rolling this out over the next month guys so amounts will vary 10-30mg from what it says on each product page please be aware. Thanks :)

Based on 125 reviews

I've only been taking these tablets about a week, so I'm hoping they will work for me I have been taking Fluoxatine for a few years now and have been fine, but I personally want to try a more natural remedy, so fingers crossed. The reviews are very good and good packaging also fast delivery. Thank you.

Really Makes a Difference

I have moderate anxiety and after reading the reviews on here, I was tempted to try out this 5HTP supplement.
Day 1 I already had a much clearer head - my heart rate became what I suspect is most peoples 'norm', and I just felt less stressed overall. I take 1 in the morning and 1 in the evening, hoping to reduce it to 1 eventually but love the fact that there are no nasties - I'm so grateful to have found a product that is non chemically and just full of facts after doing my own research on the chemical components. It has seriously helped and I will continue buying this from this fabulous company - great work guys, THANK YOU!

Supplements that work

Very happy with the three supplements I bought from you: 5htp, resveratrol and ACL..and well pleased by the pace of service.

Highly recommended for good nights sleep and to feel much happier and brighter!

My son recommended these and I have been taking 2 a day for a week. I have slept like a log each night, feel noticeably calmer and happier (find myself whistling songs) and more relaxed than I have for some time. Whatever is in them I can highly recommend and I’m a real sceptic!


Having used another (high street) brand for a while and not seeing any effects I ended up being prescribed anti-depressants. Not wanting to go down that route decided to research and ended up ordering these. Within days my mood began to lift and I started to feel a bit better. Taking 2 every day at night and hope to be able to go to 1 soon. For me they work and in my opinion a better option than prescription meds and a far better product then the well known high street brand.
