The magic of magnesium is that it can help calm stress, boost radiance, improve cognitive function, and support digestion; but not all magnesium is created equal. The best magnesium supplement for you ultimately depends on your goals, registered dietician and wellness advisor for The Lanby, Taylor Fazio, MS, RD, SPN says. “Do you need sleep and nervous system support? Help with muscle recovery and soreness? A boost for optimal cognitive function and focus? Different forms of magnesium support different results.”

Magnesium is involved in more than 300 enzymatic reactions in the body, making it foundational for overall health. “It supports optimal muscle and nerve function, energy production, healthy blood sugar regulation, stable heart rhythm and blood pressure, bone integrity, hormone balance, and restful sleep,” adds Fazio. “Adequate magnesium can also ease symptoms such as PMS, tension headaches, migraines, and constipation.”
To reap these benefits, it’s important to try and meet your magnesium goals through regular food sources from a diet rich in leafy greens, nuts, seeds, whole grains, and animal proteins. However, nearly half of the adults in the United States still don’t get enough magnesium from diet alone, making magnesium supplementation a tool for filling in the gaps. “That gap becomes even more likely in people who are physically active,” says Dr. Nima Alamdari, PhD, who serves as the Chief Scientific Officer at Ritual. “ Strenuous exercise increases magnesium loss through sweat and urine, which can raise daily requirements by as much as 10 to 20 percent, according to research.” Ahead, we asked top dieticians, nutritionists, and scientists to answer all our burning magnesium questions, including how to pick the best supplements for every concern.

Everything You Need to Know
Are magnesium supplements worth it?
Our experts agree that magnesium supplementation can absolutely be worth it. “Magnesium is involved in everything from energy to nerve signaling to muscle function and sleep regulation,” explains Fazio. “Unfortunately, modern diets, stress, soil nutrient depletion and certain medications often leave people suboptimal or even deficient.” You should, of course, try to get optimal magnesium through your everyday diet to capture food-based sources of magnesium regularly.
What are the benefits of magnesium supplements?
Supplementing magnesium can be especially helpful if you struggle with sleep, stress, muscle tension, migraines, or constipation. “Magnesium helps us turn food into energy—it’s a cofactor for several key enzymes in the citric acid cycle,” says Gerber. “It helps with muscle contraction and relaxation, pain relief, sleep, stress relief, and also helps us make certain neurotransmitters like serotonin and GABA.” In a clinical setting, Fazio sees magnesium often help individuals experiencing muscle cramps, sleep disturbances, or stress overload.
Magnesium is also a key partner in supporting bone, immune, and metabolic health. “Magnesium is required to activate and use vitamin D, too, which can help us better absorb calcium for supporting strong bones,” says Fazio. “That means that without sufficient magnesium, vitamin D supplementation may be less effective.”
Magnesium comes in several different forms, each with unique benefits. Here, Fazio breaks down the different types and benefits of each:
- Magnesium Glycinate: This form is highly bioavailable and gentle on the stomach, making it ideal for stress relief, relaxation, sleep support, and general magnesium repletion. It’s well tolerated, even for those with sensitive digestion, and is less likely to cause changes in bowel habits.
- Magnesium Citrate: This form is well-absorbed and commonly used for occasional constipation as it draws water into the stool. Taken before bed, it can promote both relaxation and a morning bowel movement. If constipation isn’t your main concern, magnesium glycinate is often a better choice.
- Magnesium Malate: This form supports energy production and muscle recovery, making it a good option for people experiencing fatigue, soreness, or chronic muscle pain.
- Magnesium L‑Threonate: This form is unique for its ability to cross the blood-brain barrier, supporting memory, focus, and overall cognitive health. It’s often chosen for those with high mental demands or for sleep support linked to brain relaxation.
- Magnesium Oxide: This form is poorly absorbed, with a strong laxative effect. It’s best reserved for short‑term constipation relief, such as during travel, and should be followed by rehydration and electrolyte support due to fluid losses.
- Magnesium sulfate and magnesium chloride: These forms are typically used topically for muscle relaxation and recovery through absorption via the skin.
What is the best form of magnesium to take?
The best form of magnesium ultimately depends on your goals. Overall, for those looking for a versatile, well-tolerated option, Gerber, Fazio, and Alamdari all agree that magnesium glycinate is the top daily choice. “For sleep and nervous system support, magnesium glycinate or magnesium L‑threonate are excellent options and pairs well with an evening wind-down routine to enhance relaxation and sleep quality,” says Fazio. “Magnesium L‑threonate also stands out for cognitive function and focus, because it can cross the blood-brain barrier.”
When it comes to occasional constipation, Fazio notes that magnesium citrate or magnesium oxide are both options. “Magnesium citrate is often the most effective choice for occasional constipation,” she says. “Magnesium oxide can be used short‑term for travel-related constipation, but it’s harsh on the digestive system and not recommended for regular use.” She recommends taking it one to two hours before bedtime, noting if you’re using it for constipation relief, bedtime dosing is often “more effective since it may take several hours to work.”
Gerber recommends magnesium malate or topical magnesium for muscle recovery or soreness, noting it’s better suited for daytime use. “Magnesium malate is best for overall energy production and muscle function,” she says. “Topical magnesium—like sulfate or chloride—can be used in a massage or bath soak.”
What to Consider When Taking Magnesium Supplements
For most people, magnesium supplements are widely considered safe and well-tolerated when used as directed. Typically magnesium can be taken at any time of day but a lot of experts find it’s helpful in the evening to support muscle relaxation and better sleep. The key is consistency, taking it daily, at a time that fits your routine. “Some forms of magnesium are better tolerated with food,” says Alamdari. “But magnesium bisglycinate is gentle enough to take on an empty stomach.”
It’s also worth noting that magnesium can interfere with the absorption of other minerals. “It can affect absorption of calcium, zinc, and iron if taken together in high doses,” says Fazio. “It may also interact with certain prescription medications, including some antibiotics, diuretics, thyroid medications, and blood pressure medications, so be sure to space magnesium at least two hours apart from iron, calcium, high-dose zinc, or thyroid medications to avoid absorption issues.” Of course, if you’re taking prescription medications or have any underlying health issues, always check with your healthcare provider before starting any new supplements.
Some people report feeling “wired” or restless after taking magnesium. “This can happen when electrolyte balance—particularly sodium or potassium levels—is off,” says Fazio. “Magnesium works closely with these other electrolytes to regulate nerve signaling and muscle function, so an imbalance may change how magnesium feels in the body.” Gerber notes that taking too much magnesium can cause further sodium depletion and electrolyte imbalances if someone is struggling with lower cellular sodium levels. “It is common in states of high chronic stress and can be tested using something called HTMA testing for intracellular mineral status,” she explains.
