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 :)

Life changer

After weaning myself off a prescribed medication which I shouldn't have been put on for low mood(default of GPs to just stick you on some tablets!) AND not wanting to be a life long customer for big pharma, I researched for something natural instead.
Found this site, read the ethos and reviews and ordered the 5HTP. Been on them 2 months and I feel like my old self already. Better general mood, feeling happy again. 100% recommend.....and it's British! Support British independant business. 5 🌟

Great products with fantastic service.

The item was of a high quality, packaged brilliantly with a quick delivery in top, the website is very informative and has a great personality of its own, I will be returning again very soon.

Game changer

For me Griffonia seed, 5-HTP has been a game changer. I'd never heard of it until 3 weeks ago. I've suffered insomnia for decades on and off which in turn causes anxiousness, irritability, mood swings, depressive bouts here and there, the usual suspects. I would put myself in the 'mild' category for these states. Anyway, I've been popping these for a couple of weeks now and the difference in my sleep pattern is quite remarkable. I can't remember a time when I've had an unbroken night's sleep but for almost 2 weeks now I've slept through without disruption. I would never write a review this excitedly if I didn't feel it truthful. For me, this is a game changer , my moods are completely different, anxiousness has disappeared and generally i feel completely lifted. Would I recommend? I think it's a works for me and no side effects.. British Supplements, excellent. Ive used them before for spirulia tabs. Always tip top products.

I’ve used British Supplements a few times in the past as I was diagnosed with MS a few years back and needed to find natural products to start fixing my body. I recently discovered 5-HTP & now taking this for just a month has made a huge difference. Sleeping is back to normal, I’m a lot happier than I was and I can focus more.

I’ve also been buying Lions Mane capsules from here too for a while and now I can’t go without them. Plus, compared to high street brands / shops, there’s no comparison. These are honest, clean products. Well recommend.
