What is Magnesium?
Magnesium is an essential mineral found in every cell, crucial for over 300 enzyme-driven processes.
Roughly 50–60% of the body’s magnesium is stored in the bones, supporting not only bone strength but also various metabolic functions.
Studies suggest it may help maintain cardiovascular health, muscle recovery, sleep quality, and more.
Magnesium Powders Can Help With:

What To Look For In A Magnesium Powder
Bioavailable Magnesium
Choose a magnesium powder that uses highly bioavailable forms—such as magnesium citrate, glycinate, or malate—which are more efficiently absorbed by the body. Less absorbable forms may lead to gastrointestinal discomfort, including diarrhea, so opt for formulations that prioritize bioavailability.
Made in the USA and Third Party Tested
Make sure the product you select is actually made in the USA, where we have strict manufacturing quality standards. In addition, you want a supplement that is third-party tested, by an independent laboratory. This will help ensure high quality and safety.
60 Day Guarantee
A reputable magnesium supplement should come with a 60-day money-back guarantee. This allows you to try the product risk-free, confident in the manufacturer’s commitment to quality.
Fair Return Policy
If you are not happy with your product, it should be easy to return your supplement. Avoid brands that make it very difficult to return a product or get a refund.
What To Avoid
Additives and Fillers
Steer clear of magnesium supplements that include unnecessary additives, fillers, or artificial ingredients. These extra components can dilute the product's potency and may cause unwanted side effects in sensitive individuals.
False or Misleading Claims
Beware of any supplements that claim their product treats or cures any specific disease or ailment, or promises miraculous, unrealistic, or misleading results. Always speak to your doctor before starting a new supplement routine.
The Lowest Priced Option
Selecting the cheapest rather than the best quality can potentially do you more harm than good. If brands don’t identify certain ingredients or nutrients and their amounts in each dose, you could end up with an ineffective or potentially harmful supplement.

Popular among athletes and health enthusiasts alike, this product also carries NSF certification for sports, underscoring its quality and purity.
However, there are a couple of considerations. Each scoop delivers 200 mg of magnesium, which may be on the lower side for those with higher daily needs.
