Every athlete knows that training sessions are just part of the equation.
Some of the real magic happens during recovery after training. Whether you're lifting weights, training for a marathon, taking long bike rides, or simply staying active through the week, you can give your body the right nutrients to support healthy recovery afterward.
That's one reason magnesium has become a favorite among athletes and fitness enthusiasts. Magnesium is involved in hundreds of biological processes throughout the body, including healthy muscle function, nerve signaling, and cellular energy production.* It's also one of the minerals athletes can lose through sweat, making it especially relevant for active lifestyles.
So, let's dive into all the ways magnesium can be a great addition to an athlete's routine.
Key Takeaways
- Magnesium supports healthy muscle function, relaxation, and recovery.*
- Magnesium is essential for cellular energy production.*
- Active individuals may lose magnesium through sweat.
- Many Americans consume less than the recommended amounts of magnesium through food alone.
- The form of magnesium matters when it comes to absorption and digestive comfort.
Recovery starts with muscle contraction and relaxation
Most people think about muscles in terms of strength. But every movement depends on two equally important actions in the muscle: contraction and relaxation.
When you're running, lifting, jumping, climbing, or cycling, your muscles are constantly contracting and relaxing in a coordinated pattern. Calcium helps trigger muscle contraction, while magnesium helps support the relaxation phase that follows.
That's why magnesium is often associated with muscle recovery. It helps support the natural processes that allow muscles to recover and prepare for the next challenge.*
Why magnesium matters for cellular energy production
Another reason magnesium is so important for active bodies is that it's deeply involved in how the body produces and uses energy.
According to the National Institutes of Health, magnesium participates in more than 300 enzyme systems involved in muscle function, nerve function, and protein synthesis. And, it's required for many of the reactions that help convert the food we eat into usable cellular energy.
For athletes, that matters because muscles don't simply need energy during a workout. The body relies on a continuous supply of energy to power movement, support nerve function, and carry out the countless processes that keep an active body performing day after day.
In other words, magnesium isn't just a muscle nutrient. It's also part of the body's broader energy-production infrastructure at the cellular level, helping support the systems that keep active people moving.
Why athletes should think about electrolytes
Magnesium, calcium, sodium, and potassium are among the body's primary electrolytes. Together, they help support fluid balance, hydration, muscle function, and nerve signaling throughout the body.
Magnesium plays a particularly interesting role because it helps regulate the movement of other electrolytes, including calcium and potassium, across cell membranes. By helping control how these minerals move in and out of cells, magnesium indirectly supports your electrolyte balance and the body's natural hydration mechanisms.
This matters for athletes because exercise changes how the body uses and distributes magnesium. During prolonged or intense exercise, magnesium is lost through sweat. It's also redistributed throughout the body to support the demands of exercise. Researchers have observed changes in magnesium status associated with sustained training and endurance activity.
This ongoing movement of magnesium throughout the body is one reason athletes might think about replenishing magnesium as part of their overall recovery strategy.
Are athletes getting enough magnesium?
Research consistently shows that many Americans consume less than the recommended amounts of magnesium from food alone.
What are the recommended amounts? Adult men generally require 400–420 mg of magnesium per day, while adult women should get 310–320 mg per day.
For athletes (or anyone), getting adequate daily magnesium can start with food. Some of the best dietary sources of magnesium include:
- Nuts and seeds
- Legumes
- Whole grains
- Leafy green vegetables
- Dark chocolate
Even with healthy eating habits, some active individuals choose magnesium supplements as a convenient way to support daily magnesium intake.
Which form of magnesium is best for active lifestyles?
Not all magnesium supplements are formulated the same way.
Magnesium glycinate, citrate, oxide, and sea-sourced magnesium all provide the same essential mineral. What differs is how the magnesium is delivered and absorbed.
Many athletes prefer forms such as magnesium bisglycinate because they are designed for absorbability and everyday use. Others look for blended formulas that combine multiple forms of magnesium.
When choosing a supplement, it's worth considering factors such as:
- Absorbability
- Digestive comfort
- Elemental magnesium content
- Whether the formula fits easily into your routine
A closer look: New Chapter Magnesium supplements
New Chapter offers a family of magnesium formulas designed to support different wellness goals and recovery routines. All three formulas feature highly absorbable magnesium glycinate (aka bisglycinate) with 2.5x better absorption.†
Magnesium glycinate complex
New Chapter Magnesium Glycinate Complex delivers 325 mg of magnesium (per 2 tablets) from three premium forms: magnesium glycinate, sea-sourced magnesium, and whole-food fermented magnesium.*
The formula is designed to support healthy muscle function, nerve transmission, bone health, heart health, and cellular energy production.* It also includes sea-sourced magnesium that provides naturally occurring trace minerals and electrolytes.
Magnesium + selenium & zinc
For active individuals looking to replenish key minerals, Magnesium + Selenium & Zinc combines highly absorbable magnesium bisglycinate, fermented zinc, and selenium in one convenient formula.
Magnesium supports healthy muscle function and cellular energy production, while selenium provides antioxidant action that helps protect cells from oxidative stress.* The formula also includes sea-sourced magnesium that delivers naturally occurring trace minerals and hydrating electrolytes, making it a great fit for active lifestyles and recovery-focused routines.*
Magnesium + ashwagandha
Looking for a more holistic daily magnesium routine? Magnesium + Ashwagandha combines highly absorbable magnesium glycinate with sea-sourced magnesium and organic ashwagandha.
The formula supports muscle relaxation and recovery*, while also providing the traditional adaptogenic herb ashwagandha. It's a convenient one-daily option for people looking to support effective training cycles or just everyday balance.
The bottom line
When people think about athletic recovery, nutrients like protein often dominate the conversation.
But magnesium deserves attention as well.
From muscle contraction and relaxation to electrolyte balance, nerve function, and cellular energy production, magnesium supports many of the systems active bodies depend on every day.*
Whether you're chasing a personal record or simply trying to recover well enough for tomorrow's workout, maintaining healthy magnesium intake is one way to support the work your body is already doing.
