If you have trouble falling asleep or wake up with restless legs, you might have heard that magnesium can help. But not all magnesium is created equal. Many people buy cheap supplements from the supermarket only to find they cause an upset stomach and do nothing for their sleep. The reason? They bought the wrong type.
Glycinate vs Oxide: Why Type Matters
The most common form found in high-street shops is Magnesium Oxide — cheap to produce, but your body absorbs very little of it (often less than 4%). The rest stays in your gut, acting as a laxative.
Magnesium Bisglycinate, which we use at Evopure, is bound to the amino acid glycine. This makes it highly bioavailable (your body actually absorbs it), gentle on the stomach (no digestive upset), and calming (glycine itself acts as a relaxing neurotransmitter).
The Science: How Magnesium Calms the Mind
Magnesium is essential for regulating your nervous system. It blocks the activity of more stimulating neurotransmitters and binds to calming receptors, helping to “quiet” a racing mind before bed. It also plays a key role in muscle relaxation, helping to physically decompress the body after a stressful day.
Why Our Blend is Different
We didn’t just stop at Glycinate. The Evopure Magnesium Sleep Blend is a complete “sleep stack” designed for deep rest:
| Ingredient | Benefit |
|---|---|
| Magnesium Bisglycinate | Superior absorption & physical relaxation |
| L-Theanine | Calms the “racing mind” (found in green tea) |
| Passionflower & Chamomile | Ancient herbs used to soothe the nervous system |
Frequently Asked Questions
When should I take magnesium for sleep?
We recommend taking it about 30–60 minutes before you plan to go to sleep to allow the body time to absorb and utilise the minerals.
Will this give me an upset stomach?
No. We use Magnesium Bisglycinate specifically because it is gentle on the stomach and does not have the laxative effect of cheap Magnesium Oxide.
Can I take this with CBD?
Yes! Magnesium and CBD work synergistically. Many customers use our Sleep CBD Oil for racing thoughts and Magnesium for deep physical relaxation.
Is Magnesium Glycinate better than Oxide for sleep?
Yes — Glycinate is much easier for the body to absorb and far less likely to cause digestive issues compared to Oxide.
