You might know that magnesium oil is TikTok's favorite topical foot-centric sleep remedy, but have you also explored this wonder nutrient as a dietary supplement? After hearing our friends talk about taking vitamin cocktails including magnesium for overall well-being, as well as mixing magnesium powders into pre-and post-workout water bottles, we were curious: What are the best forms of magnesium to take for maximum benefit? Magnesium citrate, magnesium oxide, magnesium L-Theonate and magnesium glycinate are all some of forms, including powders, tablets, gelcaps and even skin patches.

Why Take Magnesium in the First Place?

"Ongoing research has linked magnesium to heart health, mental health, premenstrual syndrome, sleep health and more recently headaches," according to registered dietician nutritionist Rachel Jones, VP and chief nutrition officer at GNC. "While additional research in these areas is needed, magnesium appears to be a truly magnificent mineral." This mineral, which is naturally occurring in that balanced diet we don't all get, is a part of more than 300 enzyme systems which regulate vital physical processes. Energy production, protein synthesis, muscle and nerve contraction, carbohydrate metabolism, electrolyte balance, normal heart rhythm and bone health all need magnesium to stay on track. Here are four forms of magnesium—and what they specifically address—that might really up your wellness game.

Magnesium Citrate (aka The One That Keeps You Calm)

Studies show this is the the form of magnesium that's most readily absorbed by our digestive tract; it's naturally found in citrus fruits and gives them their sour flavor. While small amounts enable healthy nerves and muscles, in large doses, it aids in constipation relief.

Magnesium Oxide (aka The One That Helps You Poop)

Studies show that this magnesium form is high in its concentration of the mineral, however it's got the lowest absorption rate among magnesium forms—however that low rate of absorption rate is accompanied by a laxative effect, which is why this form is often recommended as a supplement to remedy constipation.

3. Now Foods Magnesium Oxide Pure Powder

A quarter-teaspoon mixed into cold water once a day with a meal, and you're golden. (Fun fact—pure magnesium can raise water temperature on contact with it, so this is best blended with icy water)

Magnesium L-Theonate (aka The One That Helps You Focus)

This magnesium is used as a brain boost. Studies suggest that this form, which is a combination of magnesium and threonic acid, a water-based substance produced in the breakdown of vitamin C, is especially effective in concentrating magnesium in brain cells, thus suggesting applications in certain brain disorders including depression and age-related memory loss.

Magnesium Glycinate (aka The One That Helps You Sleep)

According to the Cleveland Clinic, the right level of magnesium in your body allows you to fall asleep faster, enjoy enhanced sleep quality and reduces restless syndrome, which can cause fitful sleeping. That's you'll see magnesium along with other sleep aids such as melatonin on the ingredient list of so many over-the-counter sleep aids. In our experience, magnesium glycinate helps us relax without leaving us groggy from melatonin the next morning.
