Engaging in intense workouts requires a keen focus on recovery to ensure optimal muscle health and performance. Incorporating practices such as stretching, foam rolling, and spending time in the sauna can significantly minimize muscle soreness. Additionally, you may have heard about the potential advantages of magnesium supplements. This essential micronutrient not only aids muscle function but also enhances sleep quality, which is vital for effective training recovery.
However, selecting the right magnesium product tailored for workout recovery can be challenging. With various types of magnesium and multiple delivery forms available, including capsules and topical options such as oils, lotions, and sprays, navigating the market can be overwhelming has become complicated.
Which magnesium format is most effective for recovery and promoting restful sleep? To find out, we consulted experts—a doctor, a pharmacist, and a dietitian who specialize in magnesium’s benefits.
Understanding Magnesium’s Functions
Before investing in a supplement, it’s essential to grasp its benefits. Prepare for an eye-opener: magnesium has numerous vital roles in the body.
According to Stella Volpe, PhD, RDN, a registered dietitian and professor at Virginia Tech, magnesium assists in protein synthesis, enhances bone health by activating vitamin D (essential for calcium absorption), and aids in regulating blood sugar levels.
Further, magnesium contributes to muscle recovery and improved sleep quality. Dr. Reuben Chen, chief medical advisor at Sunrider International, explains that it promotes recovery by relaxing muscles, alleviating post-exercise cramping, and restoring cellular energy.
Dr. Chen elaborates, “Magnesium also helps alleviate soreness while keeping the nervous system balanced, enabling faster recovery.” In addition, Dr. Volpe notes that magnesium plays a role in reducing inflammation, which further supports post-workout recovery.
When it comes to sleep, Dr. Chen states that magnesium calms the nervous system, preparing the body for rest. “It also plays a crucial role in regulating melatonin, the hormone that orchestrates our sleep-wake cycle, making it easier to fall asleep and maintain sleep,” he adds.
It’s worth mentioning that most experts agree that individuals usually get sufficient magnesium from a balanced diet. “As a general rule, most people are not magnesium deficient if they consume a varied diet,” notes Alexandre Chan, PharmD, MPH, a clinical pharmacy professor at UC Irvine. If you predominantly eat a plant-based diet, your magnesium intake is likely adequate. Some top food sources of magnesium include almonds, spinach, cashews, black beans, rice, potatoes, oatmeal, and salmon.
So, is there a reason to consider magnesium supplementation? Perhaps. During periods of sweat and stress, we can lose magnesium, as noted by registered dietitian Brittany Michels, RDN, LDN, CPT, in a previous GQ article. Consequently, if you find yourself drenched after a workout, replenishing magnesium could be beneficial.
However, moderation is key. With magnesium, excess amounts can lead to negative effects. The National Institutes of Health advises that adult men should aim for 400 to 420 milligrams daily, while exceeding 5,000 milligrams can be toxic. Symptoms of magnesium overload include nausea, diarrhea, muscle weakness, respiratory difficulties, and heart palpitations.
