Magnesium for Endurance Athletes: Dose and Sweat Loss

Magnesium supplementation helps performance mainly in athletes who are low in magnesium; in active people with adequate levels, controlled research has not shown a performance gain.

According to the National Institutes of Health (NIH), the recommended daily allowance of magnesium for adult men is 400-420 mg/day, and for adult women, it is 310-320 mg/day.

Green leafy vegetables, such as spinach, legumes, nuts, seeds, and whole grains, are good sources [1,3]. In general, foods containing dietary fiber provide magnesium.

Magnesium for endurance athletes

Sports Medicine Reports: Magnesium is the fourth most abundant mineral and the second most abundant intracellular divalent cation in the body. It is a required mineral that is involved in more than 300 metabolic reactions in the body.

Magnesium plays a role in muscle function: Magnesium is involved in the contraction and relaxation of muscles. Adequate magnesium levels may help prevent muscle cramps and spasms, a common issue for endurance athletes. It's clear that magnesium can be part of your effort for physical performance.

Runners World: Magnesium might also help reduce the accumulation of lactic acid during hard sessions.

The role of magnesium in energy production for endurance performance

Magnesium is involved in energy production: Magnesium plays a role in the production of ATP (adenosine triphosphate), which is the body's primary energy source. Supplementing with magnesium may help improve energy production and support endurance.

What the controlled research shows is narrower than the supplement marketing:

How magnesium may help reduce fatigue in endurance athletes

Magnesium may help reduce fatigue: Some research suggests that magnesium supplements may help reduce fatigue, particularly in individuals who are deficient in magnesium. This could benefit endurance athletes, who often experience fatigue during training and competition.

Magnesium and protein synthesis for muscle recovery in endurance athletes

Magnesium is involved in protein synthesis: Magnesium is necessary for synthesizing proteins, which are essential for muscle repair and recovery. Supplementing with magnesium may help support muscle recovery and repair in endurance athletes.

Research Study: Magnesium is a cofactor involved in many enzymatic systems, being necessary for protein synthesis, functioning of nervous and muscular systems, regulation of blood pressure and glycaemia, bone metabolism.

The potential benefits of magnesium for immune function in endurance athletes

Magnesium may support immune function: Some research suggests that magnesium may help support immune function, which could be beneficial for endurance athletes who may have a higher risk of infection due to increased physical stress.

Magnesium for digestion

Magnesium helps to relax the muscles of the digestive tract and can help to relieve constipation. It is also necessary for the proper absorption of other nutrients, including calcium, zinc, and vitamin D.

Yunique Medical: Firstly, it works as an osmotic. That is, it pulls additional water into the intestines. Not only does this lubricate the entire tract so waste can move through it more quickly, but it also adds to the size of the stool, causing it to be pushed out more easily.The second of magnesium’s constipation prevention powers is its ability to relax the intestinal wall muscles.

What causes a magnesium deficiency?

“Ultimately, making sure your body is getting enough magnesium not only helps you maintain good health in general, it also may help you manage stress, migraines or muscle aches and pains,” Cleveland Clinic's Dr. Umeda says

Magnesium deficiency can occur due to a number of factors, including the consumption of refined oils and grains, soil depletion, and the use of fertilizers that diminish mineral absorption.

Many packaged foods contain refined oils that remove all magnesium, while refined grains and sugars can remove 80-97% of the mineral. In addition, the depletion of nutrients in the soil and the use of fertilizers can reduce the amount of magnesium that is absorbed by plants, leading to lower levels of the mineral in the foods we eat.

What are some of the symptoms of magnesium deficiency?

Here is a quick list from Healthline:

• Muscle twitching or muscle cramps

• Mental Health -Mood CHanges, Memory Problems

• Osteoporosis

• Rapid heartbeat

• Fatigue, Numbness and Muscle Weakness

• Blood Pressure regulation

• Asthma

• Irregular Heart Beat

Here's a list of magnesium rich foods

1. Pumpkin seeds (roasted) 532

2. Almonds 300

3. Brazil nuts 225

4. Sesame seeds 200

5. Peanuts (roasted, salted) 183

6. Walnuts 158

7. Rice (whole grain brown) 110

It is important to note that while magnesium supplements may have some potential benefits for endurance athletes, it is generally recommended to get nutrients, including magnesium, from a varied and balanced diet. It is a good idea to speak with your healthcare provider about magnesium intake needs.

Magnesium is not something Endurance360® provides in a dosed amount, so treat it as a separate line item; see potassium for endurance athletes for how the electrolyte trio works together, and use the sodium calculator to size your overall electrolyte replacement plan.
