Excellent Sleep with Unmatched Quality!

"This magnesium glycinate is really good. I did not start taking it until about 6 months ago, and NutraBio is the only product I will buy. I get an excellent sleep stacking this and a couple of other NutraBio sleep products and I sleep like a baby. The quality and the trust I have in NutraBio is why I continue to come back to NutraBio for all our supplement needs."

The best form of magnesium!

"Coming from nutrabio, you can absolutely trust the quality of this supplement. Top tier. I've been waiting for this form of magnesium. And finally. Lol. The best. Would love to see more single supplements like boron, fadogia agrestis, vitamin A and E, pine pollen extract, shilajit extract, astaxanthin, saw palmetto extract, etc. Maybe hopefully soon.

Q&A

Frequently Asked Questions

Does magnesium glycinate help with sleep?

Magnesium glycinate is commonly used to support relaxation and sleep quality because magnesium plays a role in calming the nervous system and muscle relaxation. While it is not a sleep aid or sedative, many people find it helps them unwind and supports more restful sleep when taken consistently.

When is the best time to take magnesium glycinate?

Magnesium glycinate can be taken at any time of day, but many people prefer taking it in the evening due to its calming effects. It can also be taken post-workout or before bed depending on personal preference and wellness goals.

Can magnesium glycinate cause diarrhea or stomach upset?

Magnesium glycinate is one of the gentlest forms of magnesium and is far less likely to cause diarrhea compared to forms like magnesium oxide or citrate. Its chelated structure allows for better absorption, reducing the amount of magnesium left in the digestive tract.

How long does it take to feel the effects of magnesium glycinate?

Some people notice benefits such as muscle relaxation or improved sleep within a few days, while others may experience more noticeable effects after consistent daily use for one to two weeks. Results can vary based on individual magnesium levels and lifestyle factors.

Can magnesium glycinate be taken with other supplements?

Yes, magnesium glycinate stacks well with many other supplements, including protein, collagen, omega-3s, multivitamins, and wellness-focused formulas. If you are taking medications or high-dose mineral supplements, consult your healthcare professional before use.
