What Others Say

About Biosphere Magnesium

“I suffer migraines and I was put onto magnesium which has 3 special ingredients (which this products has) I’m happy to say that after 10 years of acute migraines, since taking this product I haven’t had a migraine in 3 weeks.”



I can't swallow pills, so was very pleased to find this powder that can be mixed with water to drink down. Was pretty skeptical but figured it was worth a try as I am a real insomniac and also get shocking calf cramps in the night. I have to say the cramps have gone which is amazing, and I'm getting a little sleep most nights now. Will definitely continue with this magnesium product.



“Definitely the tastiest magnesium supplement I've had, and it's really effective too. Doesn't upset my stomach, and the lemon lime flavour is lovely. It's not as cheap as others on the market, but for good reason. I won't go back to any other brand now! Having it on subscription has been great too, no needing to remember to buy more each month.”



“I have terrible insomnia, the tossing and turning , not being able to sleep and then when I finally did I would wake up every hour on the hour. I tried everything but nothing seemed to work until I tried this. I get to sleep quickly and stay asleep, I may wake up once but get back to sleep and stay asleep.”
