Rae Basics Magnesium Glycinate NO. 04 bottle resting on linen at bedtime

Most "magnesium glycinate" is hiding cheap magnesium oxide.

Read the label. If it says "buffered," the bottle is padded out with poorly absorbed oxide that can leave your stomach upset and your levels low. NO. 04 is the real thing.

What to expect

Your wind-down, week by week.

First nights

Taken about an hour before bed, many people notice they wind down more easily and the racing-mind feeling settles.

Week 1

A daily ritual takes hold. Because it is non-buffered, it stays gentle on your stomach where oxide forms often are not.

Weeks 2–3

As intake stays consistent, NO. 04 supports muscle relaxation and those tense, tight-shoulder evenings.

1 month +

With levels topped up, NO. 04 supports a calm nervous system, restful sleep, and healthy magnesium status day to day.*

From a nurse who was tired of guessing

Hi, I'm Skotie.

As a nurse, I read labels for a living. So when I went looking for a magnesium that would actually help me sleep, I was floored by how many "glycinate" bottles were quietly padded with magnesium oxide, the cheap stuff that barely absorbs and wrecks your stomach.

I wanted one I could hand a patient, a friend, my own mom, without a single asterisk I had to explain away. So we made it. Pure, non-buffered bisglycinate. Tested. Published. Nothing I would not take myself.

NO. 04 is the magnesium I wish had existed years ago. I hope it gives you the calm evenings it gave me.

Good questions

Everything you might ask.

Many magnesium glycinate products are "buffered," meaning they are diluted with magnesium oxide to lower cost. Oxide is poorly absorbed and tends to upset the stomach. NO. 04 is 100% non-buffered bisglycinate, so what is on the label is what your body gets.

Each serving delivers 200mg of elemental magnesium from 1,700mg of magnesium bisglycinate. One bottle holds 90 vegan HPMC capsules, which is 30 full servings, a clean monthly supply. Besides the magnesium, the only other ingredients are tapioca starch and the vegan capsule itself.

Most people take three capsules in the evening, about an hour before bed, with a little water. It can also be taken with a meal if you prefer. Consistency is what helps levels build over time.

That is exactly why we use the glycinate form and skip oxide. The bisglycinate form is well tolerated and far gentler than the oxide and citrate forms that send many people running.
