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 :)

Game changer

After weaning off of fluoxatine because of unwanted side effects I started taking 5htp about 3 years ago. Without it my mood is low and I have unwanted thoughts. Usually have a break every 3 months to see if I can manage without it. Within 2 days symptoms return and I'm straight back on it. Take many other supplements from BS. Will only use these. Have literally changed my life

Clean 5htp

I tried your 5htp last night for the first time. I can say it was best nights sleep for a very long time. Since menopause i haven't slept well at all. Most nights i just feel i wake every hour or so and never shut off completely to a good sleep. I slept from 11.30 to 6.30 without waking, which is brilliant. Thanks British supplements. I will review my other supplements when i have tried them. I support and buy off lots of small businesses, and will continue to buy from British Supplements and nowhere else. I shall be recommending to friends and family.

Really became a must have for me..

I take 5THP because of the clarity of mind it gives you and upbeat mentality. It also improves sleep… I’m an easy sleeper though.

I take these in bursts when I have high demands on me in terms of work performance, mental pressure and actually being able to flip my capabilities on/off quickly.

It’s all very subtle, some of my friends now take it and again said it doesn’t make you feel groggy or anything. And just is a little prop for times you may need a bit of a boost!

Mood changing!

I bought these tablets after reading about them online. I am aged 49, in perimenopause, and have had so many hormonal mood problems throughout my life, with 2 out of every 4 weeks of the month feeling very low, tearful, irritated and angry when my period was coming up. I never wanted to try chemical solutions such as antidepressants and I have tried every herbal solution available, some of which have helped slightly over the years. Since entering the perimenopause a few months ago, my low mood has been awful. I have been taking these tablets along with the ashwaghanda, magnesium and turmeric for the last few weeks, and I have to say I have noticed a HUGE improvement in my mood! I have also noticed a reduction in my awful neck and shoulder pain, caused by cervical spondylosis for which I was forced to take co-codamol. I have not taken co-codamol now for 3 weeks. I have taken all of the above apart from the 5-HTP before via other brands, but have never felt this good on any of them, which goes to show how much rubbish is in other brand's tablets. I find it hard to swallow the tablets so I just open them and add the powder to water. The turmeric tastes lovely! So happy to have found this company that has made such a difference to my mood.

Feel like a different person

I am a healthcare professional. I have also been in recovery from bulimia for 3 years. I was recommended ashwaganda for my anxieties around food etc by my therapist, and found British Supplements. After looking at the stacks, I thought I'd also give 5HTP a go. I'd heard about it before and during the beginning of my recovery my GP suggested going on antidepressants but I didn't want to. Back then I'd looked it up but didn't give it a thought. I did some research into 5HTP and thought I'd give it a shot now. Anyway, my life over the past month has significantly changed. I used to stand for hours looking at myself in the mirror scrutinising my body, hating myself, consumed with thoughts of losing weight. After 2 weeks I felt those thought processes start to disappear. It's now been 7 weeks and I look in the mirror at a different person. I feel like I've got my life back. My mood is happier, my partner can see the difference in me. I also starting regular yoga classes when before I used to get consumed sitting on the sofa scrolling through the internet looking for ways to loose weight fast. My time would disappear. I just despised any sort of exercise. Now I'm doing yoga, walking, even the occasional run! I have weekly therapy and even my therapist has seen a difference in me. To the point we've dropped the amount of sessions I have. I really was at breaking point, the lowest I've been in my recovery. Ashwaganda and 5HTP has restored my brain to a point where I can live my life again! No anxieties, no deep depression. I have told SO many people about this recently, I can't believe the improvement. Thank you so much Chris and the team!!!!
