Best Magnesium Supplements: Top 5 Products, According To Health Experts

Magnesium may not be a supplement that is talked about often, but it is absolutely crucial in a healthy, functional body. This element plays an important role in protein synthesis, proper muscle and nervous system function, and regulating blood sugar and blood pressure. Magnesium is also known to improve sleep. Though it’s usually best to get most of your vitamins and minerals from the food you eat, many people are deficient in magnesium without even knowing. Keep reading to find out what some of the best magnesium supplements on the market are to add to your diet.

Besides being an important element for healthy body functions, adding more magnesium to your diet may actually slow brain aging and ward off dementia. According to a study from Australian National University that included 6,000 participants, a higher dose of magnesium each day may keep dementia at bay. Study authors report more magnesium on a daily basis leads to stronger brain health as we age. Moreover, eating lots of magnesium-rich foods (spinach, pumpkin seeds, nuts) may also help lower the risk of dementia.

Eating magnesium rich foods (or taking a magnesium supplement!) can also help lower your risk of cancer. In a study from the University of Basel, researchers find foods rich with magnesium — including avocados, spinach, bananas, and beans — all help to boost the immune system. Study authors say magnesium levels are an important factor in the body’s ability to stave off tumors and infections. Being low in magnesium increases the risk of diabetes, high blood pressure, heart disease, osteoporosis, and even Alzheimer’s. 

Magnesium was even recommended by StudyFinds’ dietician Shyla Cadogan. “If you asked me which vitamin is most worth it, I’d say magnesium,” writes Cadogan. This is for many reasons. Taking it daily can help with debilitating period cramps, consistent muscle pains and aches, and poor sleep. Plus, it regulates blood sugar and blood pressure. One psychologist calls it “the original chill pill,” thanks to it showing great promise in patients with depression, anxiety, insomnia, and stress management.

Why Supplement with Magnesium?

Unfortunately, modern diets often fall short in providing the recommended daily intake of magnesium (400-420mg for men, 310-320mg for women). This deficiency can manifest in a variety of ways, including:

  • Muscle cramps and spasms
  • Fatigue and low energy levels
  • Insomnia and sleep disturbances
  • Anxiety and depression
  • Headaches and migraines
  • High blood pressure

Supplementing with magnesium can help address these deficiencies and unlock a multitude of health benefits:

  • Improved sleep quality: Magnesium acts as a natural relaxant, promoting deeper sleep and reducing nighttime restlessness.
  • Enhanced muscle function and recovery: Magnesium is crucial for muscle contraction and relaxation, aiding in exercise performance and preventing cramps.
  • Boosted energy levels: Adequate magnesium levels contribute to efficient energy production, combating fatigue and brain fog.
  • Reduced anxiety and stress: Magnesium’s calming properties help regulate mood and alleviate symptoms of anxiety and stress.
  • Stronger bones: Magnesium plays a vital role in bone health and mineral metabolism, contributing to bone density and reducing the risk of osteoporosis.
  • Better blood pressure control: Magnesium helps regulate blood pressure by relaxing blood vessels and improving blood flow.
