How do we compare ?
  • 99% of Companies sell Blends with this and that and all the Nasty extras - Update ours is now a blend but not one of those dodgy ones. Its 9 part Mag-L and 1 part uptake blend to help deliver our product(s).
  • One of the Strongest Online :)
  • If Price means everything then our Supplements are not for you. There is penalty of poor supplements out there, all big brands included for the most part.

Plus our products are CLEAN they all add Nastys because they are made for money and not for human consumption.

* 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 :)

Magnesium L -Threonate

Definitely one of my favourites and will have leg cramps if I don’t take it regularly.


I have been having a lot of trouble with anxiety, through family illness and not sleeping. After having my blood pressure taken at the Dr’s ( I went with frozen shoulder) She said my BP was way too high, I explained it was with stress & it would be ok. She insisted I should be on medication. I really didn’t want to go down that road & googled & found out Magnesium could help also good for pain.I read that Mag L- Threonate was the one to help & found it on B S website. Delivery was quick & the 2nd day of taking it I slept like a log!!! Also I took my BP twice a day keeping a diary for a week & straightaway it went back down to normal. I will definitely carry on with the magnesium and when I speak to the Dr again convince her I do not need to start on medication. I am 70 & have managed without anything up to now. Must just say obviously very impressed with BS have sent for 3 other supplements since. Keep up the good work & Thankyou for all that you do.
