“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.”


(verified buyer)

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 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


(verified buyer)

I love this stuff! Started drinking it instead of the (way too many) cups of coffee I drank on a daily basis. I mix my dust with some warm oatmilk and I'm genuinely looking forward to drinking every morning. Keeps me alert and, most important for me, reduces anxiety. And the cacao flavor is a nice bonus. 10/10 would recommend.

Why Magnesium is Essential?

Understanding the Critical Need for Magnesium

Magnesium is more than just a mineral; it's a necessity for maintaining optimal health. However, the World Health Organization (WHO) reports that approximately 75% of people in Western countries don't meet their daily magnesium needs. This widespread deficiency can be attributed to several factors:

Regular Stress: In today's fast-paced world, chronic stress is common, increasing the body's magnesium requirements.

Nutrient-Depleted Diets: Modern agricultural practices have depleted magnesium levels in our soil, leading to lower mineral content in our foods.

High Consumption of Processed Foods: These foods not only lack essential nutrients but also accelerate the depletion of magnesium in our bodies.

Lifestyle Choices: Excessive caffeine, sugar, and alcohol intake can hinder magnesium absorption.

Magnesium deficiency can manifest in various ways, including fatigue, muscle weakness, high blood pressure, and irregular heartbeat. By supplementing with a high-quality magnesium product like ours, you can replenish your body's magnesium levels, supporting overall health and well-being.

Remember, not all magnesium supplements are created equal. Our Biosphere Magnesium provides a potent, bioavailable form that's easily absorbed and utilised by your body, ensuring you get the full spectrum of benefits this essential mineral has to offer.
