Top 5 Magnesium Supplements in 2025
Find out which supplements actually work and which to stay away from
IMPORTANT: If you’re trying to find the best magnesium supplement in 2025, you're in the right place. We tested the top 5 brands. Our research reveals the biggest mistakes shoppers make, why most magnesium is toxic, and which brand has 46x's less heavy metals than everyone else.
What is Magnesium?
Magnesium is a mineral found in every organ in your body. It is critical to bodily functions, the nervous system, and bone density. It is the most abundant mineral in the human body and has over 3,000 receptor sites.
According to Harvard University, more than 75% of adults are magnesium deficient because they aren't getting enough through their diets.
Normally, we receive magnesium through our diet, leafy greens, nuts, beans, and fish. Because our food quality is getting worse, and chemicals are sprayed into our air, we have difficulty holding minerals in our bodies.
As we age, the problem is compounded. The result is a population where many of us are magnesium deficient. Supplementation is commonly suggested by medical practitioners.
According to PubMed.gov total and intercellular magnesium (found in our bones and cells) tend to decrease with age. Chronic deficiency has been linked to fatigue, depressed mood, inflammation, hypertension, diabetes, sleep, and heart issues.
However, adequate magnesium over long periods of time shows an increase in mineral levels in bones, and may prevent joint-related disease; it can balance muscular cramping and calm stress, which may help counteract the aging process.
Studies show supplementing magnesium may help with muscle recovery and spasms, helping us sleep. It has a critical role in stabilizing the nervous system and blocking stress-related responses, helping us calm down.
Magnesium also can help block cortisol, the stress hormone that packs on the pounds. It increases water in the intestines, which is why it's used as a laxative.
Benefits of High Quality Magnesium
Magnesium supplements can be a cost-effective way to deal with a number of issues. With the right supplement, you could feel a difference from just 2-3 weeks. Below are just some of the main benefits of high quality turmeric supplements:
Reduce Stress
Magnesium can block stimulating neurotransmitters and bind to calm and restful receptors in your brain. It can diminish stress response and help us relax.
Reduce Muscle Cramps
Magnesium is believed to alleviate pain associated with cramps, and reduce the frequency and intensity of them.
Promote Sleep
Multiple studies have shown magnesium to reduce the time it takes to fall asleep, increase the duration of sleep, and reduce nighttime wake ups.
Supports Blood Pressure
One of the most common doctor recommendations for reducing blood pressure is magnesium glycinate. There are many documented studies supporting this use case.

Low Glycinate Content

The Bottom Line
Magtech by Natural Stacks is a good magnesium product, containing 200mgs per serving. It's made up of 3 magnesium salts including threonate, glycinate, and taurate.
We would recommend going with a magnesium glycinate or citrate-only product like our #1 and #2 pick, so you get the best absorbability.

The Bottom Line
This formula is suitable for vegans. It contains 200mgs of magnesium glycinate per serving, which is standard for most brands. It has a 90-day return policy.
Upon further investigation of their capsules, they are tinted brown, which is likely reflective of the binders and additives.
If you look at the "other ingredients" on their label, there are 3 fillers/additives.

The Bottom Line
This is one of the best-selling supplement brands overall. Their magnesium caps have a blend of 3 magnesium types because this is cheaper than pure glycinate.
It is mostly magnesium oxide which is not very absorbable and very cheap. These low-end magnesium salts pass through the body with minimal absorption. This option is better than nothing, and the brand has been around for a while.Price starts at $29.99
