Better Sleep Quality: Studies show that magnesium helps maintain healthy levels of GABA, a neurotransmitter that promotes sleep quality, sleep duration and non-REM sleep.*

Improved Exercise Performance and Recovery: Magnesium plays a central role in regulating muscle contraction and relaxation, promoting energy metabolism, balancing electrolytes, and reducing tiredness and fatigue.*

Heart Health Support: Magnesium is vital for maintaining a healthy heartbeat and is involved in transporting other electrolytes, such as calcium and potassium, into cells. These electrolytes are crucial for nerve signals and muscle contractions of a healthy heart.*

Bone Health: Magnesium plays a key role in bone formation and influences the activities of osteoblasts and osteoclasts, cells responsible for the health of your bones.*

Great for sleep

This has definitely improved my sleep! It took about one 15 days to start working, which is expected for this type of product, but I can now see a noticeable difference in my sleep quality.

Could not be happier

I like it, it makes me feel better. I have more energy, I sleep better.

Buy it!

As someone who frequently goes on long bike rides, I often face challenges with muscle soreness and calming down before sleep. This particular magnesium supplement has made a noticeable difference. My sleep quality has improved markedly, and muscle cramps have become much less frequent. Regularly taking this supplement at night has really improved my sleep quality and post-exercise recovery.

Works great!

I take it before heading to bed, and based on my watch's data, I experience a significant increase in deep sleep duration.

Stefan K.
Great supplement!

The best magnesium glycinate out there, hands down. It's not only affordable but also assists me in falling asleep more quickly and ensures a deep, undisturbed sleep throughout the night. Taking it 30 minutes to an hour before bedtime works wonders for me.

Lucas H.

Great option to take before bedtime.

Frequently Asked Questions

Why magnesium is important?

Magnesium ranks as the fourth most prevalent mineral in our bodies, playing a pivotal role in supporting more than 300 vital functions. Despite its importance, up to 75% of Americans suffer from a deficiency in this crucial mineral.

Factors such as monoculture farming, large-scale agricultural practices, and excessive processing in our food supply chain have led to diminished magnesium levels in our daily diets. A deficiency in magnesium can trigger a cascade of problems, such as mood disturbances, difficulties with sleep, muscle spasms, and challenges in absorbing critical vitamins and nutrients, including vitamin D.

How is it magnesium glycinate different from other forms of magnesium?

Magnesium glycinate combines magnesium, an essential mineral, with glycine, an amino acid. This combination is highly bioavailable, meaning it's easily absorbed by the body, and tends to be gentler on the stomach than other forms of magnesium. Unlike magnesium oxide or magnesium citrate, which may cause gastrointestinal discomfort or a laxative effect, magnesium glycinate is less likely to cause these issues, making it a preferred choice for those with sensitive digestive systems or for those looking to avoid these side effects.

Is magnesium important for my gut health?

Yes. Magnesium is essential for maintaining gut health because it supports muscle contractions in the gastrointestinal tract, which helps move food along and regularizes bowel movements. Moreover, some studies suggest that magnesium can enhance the gut's microbiome, the community of beneficial bacteria that resides in our intestines and plays a crucial role in our overall health.
