Magnesium Benefits

Research has shown there are several health benefits to maintaining sufficient Magnesium levels. The best way to enjoy these benefits is to get the daily recommended amount of Magnesium through food and supplement.

  • Improves Cellular Energy Production:
    Found in the mitochondria—the powerhouse of the cell—Magnesium is needed to maintain the function of the electron transfer chain that converts food into adenosine triphosphate (ATP) molecules. This makes it essential for multiple body processes.
  • Enhances Exercise Performance:
    Magnesium has a positive impact on physical performance in both elite athletes as well as elderly people who want to stay active. This is also brought on by the mineral's impact on energy levels.
  • Supports Mood Regulation:
    Magnesium is a key mineral for healthy brain biochemistry as it helps to balance levels of brain chemicals called neurotransmitters. Boosting Magnesium levels has been shown to reduce feelings of anxiousness.
  • Encourages Relaxation:
    Taking Magnesium supplements encourages relaxation, making it easier to fall into a restful sleep. It also positively influences levels of melatonin, a hormone that regulates the sleep-wake cycle.
  • Reduces Headaches:
    Increasing your Magnesium intake is popular in preventing and reducing debilitating tension headaches and migraines. It may help by reducing muscle tension and relaxing blood vessels, thus improving circulation to the brain.

What Causes Low Magnesium

Magnesium is needed for many functions in the body. This condition, also known as hypomagnesemia, includes the physical and chemical processes in the body that convert or use energy. When the level of Magnesium in the body drops below normal, symptoms develop due to low magnesium.

Causes of Low Magnesium

Magnesium deficiency is a condition in which the amount of Magnesium in the blood is lower than usual. This can be brought on by several causes, ranging from illnesses to other behaviors.

  • Malnutrition: A lack of a nutrient-rich diet can cause fat malabsorption, leading to Magnesium loss over time.
  • Excessive Alcohol Use: Excess alcohol consumption can increase Magnesium excretion.
Low Magnesium Symptoms

Many symptoms can emerge from Magnesium deficiency. That's because of the mineral's impact on a litany of metabolic processes.

  • Fatigue and Weakness: Magnesium levels directly impact energy levels, with low Magnesium counts resulting in quicker exhaustion.
  • Nausea and Vomiting: Low Magnesium levels have been connected to malabsorption in the intestines, linked to several gastrointestinal issues.
  • Muscle Twitches or Cramps: Cramps and twitches can have many causes, and one reason is low Magnesium levels.

What To Look For in a Magnesium Supplement

Not all Magnesium supplements are made the same. It's important to have supplements including multiple nutrients that work with Magnesium to have a crucial role in overall health. Here are some essential factors to remember to ensure you get the most Magnesium concentration out of your supplement.

  • Dosage: As an essential nutrient, the body's Magnesium levels need to be replenished daily from diet and supplementation. Try to keep your daily intake of Magnesium between 300-400 mg. Learn more
  • Type: Magnesium Citrate and Glycinate are two main types of Magnesium. Citrate can help with issues such as constipation, while Glycinate is often taken to help with anxiety, sleep, and inflammatory conditions. Learn more
  • Pairs Well With: Magnesium and Vitamin D3 supplements can be taken together to ensure that the body functions adequately. Magnesium and zinc also work well to boost the immune system. Learn more
  • Quality: Choose products with third-party safety and quality certifications, like the U.S. Pharmacopeial Convention (USP) or NSF International. This will ensure that you're getting the amount of Magnesium on the label without any unwanted ingredients and additives. Learn more
  • Manufacturing Process: Look for products that come from brands that adhere to the Food and Drug Administration's (FDA) Current Good Manufacturing Practices (CGMPs). Learn more

More Questions You Have About Magnesium, Answered

Our library of expert-authored articles covers just about every question you might have about vitamins, minerals and supplements — along with some you might not have known you had.

Which Magnesium is best for sleep and anxiety?

Magnesium glycinate is often used for its calming effects. Magnesium blocks the activity of more stimulating neurotransmitters in the brain and binds to calming receptors, resulting in a more peaceful, resting state.

What does Magnesium do for the body?

Magnesium is essential for maintaining good health and plays a key role in everything from exercise performance to heart health and brain function. It helps with hundreds of vital body processes, so it's essential to maintain your Magnesium levels and consult with your doctor if you notice the symptoms of a lack of Magnesium, such as fatigue and gastrointestinal issues.

How long does Magnesium stay in your body?

The process of absorption is pretty quick for Magnesium. Most Magnesium stays in the body anywhere from 12 to 24 hours, so it's essential to adhere to a recommended daily allowance of the mineral.

When should you take Magnesium?

Magnesium supplements can be taken at any time of the day as long as you can take them consistently. For some, taking supplements first thing in the morning may be easiest. Others opt for taking them at night because of the calming properties of Magnesium.
