Magnesium For Muscle Pain
In this section, we go deep into the specifics to learn how magnesium for muscle pains can boost performance, help relieve delayed onset muscle soreness, and boost your workout recovery.
How Does Magnesium Help Sore Muscles?
Magnesium's ability to bring relief to your aching muscles comes from a combination of the following factors:
- Muscle Relaxation: An essential function of magnesium is to act as a muscle relaxant. It achieves this by controlling calcium ions, which are vital for muscle contractions. By preventing excessive calcium build-up in muscle cells, magnesium promotes greater relaxation.
- Anti-Inflammatory Effects: Muscle discomfort is frequently caused by inflammation. Magnesium possesses anti-inflammatory qualities that can aid in reducing the discomfort and swelling brought on by achy muscles. As a result, magnesium helps the body recuperate by reducing inflammatory reactions.
- Better Blood Flow: Magnesium helps maintain healthy blood flow, ensuring muscles get enough oxygen and nutrients. By removing waste from muscular tissues, the improved circulation aids in accelerating recovery and reducing discomfort.
- Electrolyte Balance: Magnesium is one of the electrolytes that must be properly balanced for muscles to operate correctly. When you work out, magnesium can be lost through sweat. Magnesium replenishment aids in maintaining this equilibrium and guards against cramps and muscle tightness.
- Nerve Activity: Nerve irritation frequently causes muscle soreness. Magnesium helps to lower neural excitability and is essential for proper nerve function. Magnesium can reduce pain and discomfort by calming the nervous system.
- Replenishing ATP: Magnesium is needed to create adenosine triphosphate (ATP), the muscle's energy currency. With greater energy, muscles can recover faster.
- Better Sleep: Rest is essential for the rehabilitation of muscles. Magnesium is known for relaxing the nervous system and encouraging sound sleep. Your muscles can mend and regenerate themselves more efficiently with plenty of sleep.
A 2022 study looked at the effect of magnesium supplementation on muscle soreness and performance among college-aged male and female subjects. The magnesium group took 350 mg of magnesium per day for ten days. Compared to a placebo group, the magnesium group had significantly reduced delayed onset muscle soreness, as well as a reduced rate of perceived exertion and improved perceived recovery (2).
How Long Does Magnesium Take To Work For Muscle Pain?
The length of time it takes for magnesium to bring muscle relief can vary quite a bit between individuals. Here are the key factors that affect it:
- Form: The form of magnesium you take can affect how quickly it acts. While some types, such as magnesium citrate, are rapidly absorbed and may offer relief very quickly, others, such as magnesium oxide, are less accessible and may take longer to work.
- Dosage: The magnesium dose you take is important. Higher doses could offer more speedy relief, but adhering to suggested daily limits is critical because too much magnesium can cause stomach discomfort.
- Individual Variation: How each person's body responds to supplements varies. While some people can feel better in hours, others might need a few days to detect a difference.
- Muscle Pain Intensity: Muscle soreness or pain intensity also has an impact. Magnesium supplements may work faster to relieve mild discomfort than on more serious muscular aches or injuries.
- Consistency: Consistency is crucial while taking magnesium supplements. Magnesium levels in your body could take some time to balance out. Thus, regular supplementation can lead to improved outcomes over time.
- General Health: The rate magnesium acts depends on your general health. It can take longer to feel better if underlying medical issues prevent magnesium from being absorbed or used properly.
- Diet: Your diet and hydration level can affect how much magnesium is absorbed. Supplementation may be complemented with foods that contain magnesium. Keeping hydrated is also necessary for magnesium to function at its best.
- Stress & Sleep: Stress management and enough sleep both help magnesium work more effectively. Addressing these issues can lead to quicker treatment because prolonged stress and lack of sleep can increase muscle pain.
Although most people start to feel some relief from their muscle pain, remember that magnesium is not a magic bullet for severe pain or recent muscular injuries. A healthcare expert should be consulted for a thorough treatment plan if you have a specific muscle injury.
Does Magnesium Help With Muscle Cramps?
Magnesium has gained acceptance as a viable natural treatment for easing muscle cramps, and research suggests that it may be helpful in some circumstances.
To start, magnesium is a crucial mineral for the health of muscles because it helps control how they contract. It does so by opposing calcium, which is necessary for muscular contraction. By preventing the excessive calcium build-up in muscle cells, magnesium helps reduce the risk of cramping.
Magnesium can be lost through heavy sweating or activity, which can cause imbalances and raise the possibility of cramping. As such, magnesium dietary supplements help reestablish the electrolyte equilibrium.
Overactive nerves can contribute to cramping in the muscles. Magnesium helps soothe nerves by preventing the production of neurotransmitters that might cause muscles to contract.
Finally, magnesium promotes healthy blood flow, ensuring muscles receive enough oxygen and nutrients. This improved circulation, especially after a workout, might lower the chance of cramping.
Most interestingly, there is some promising research regarding the use of magnesium for cramps. A 2014 study published in the American Journal of Clinical Nutrition found that supplementing with magnesium reduced the incidence of leg cramping in elderly women (3).
Anecdotal evidence also supports the use of magnesium for muscle cramps. Here are a couple of comments from users on Reddit:
"I like taking 100-200 mg magnesium malate in the morning and 100-200 mg magnesium glycinate at night to dull muscle pain/cramps. Sometimes I'll use a topical spray at night if it's really bothering me. (source)"
"Hell yeah, magnesium has nearly completely eliminated my calf and foot cramps. I started taking 400-600mg/day back in early summer, and the only time I've had any since has been when I don't take mag for a week or so. It is definitely one of my favorite supplements because it has made a noticeable impact. I take the taurate and malate forms, but it seems everyone has their own preference. Definitely worth exploring the different types, most are pretty cheap besides threonate and magtein." (source)
It is important to note that magnesium deficiency is not the only cause of muscle cramps. They can also be caused by dehydration, excess effort, and specific medical disorders.
Is Magnesium Good For Muscle Recovery Post-Workout?
Yes, magnesium can definitely help with post-workout muscle recovery in more than one way:
- Calcium Control: After an intense workout, your muscles may become tight and worn out. By controlling calcium ions, which are necessary for muscular contractions, magnesium helps reduce muscle tension. This calming effect helps lessen muscle soreness and stiffness after exercise.
- Inflammation Reduction: Magnesium's anti-inflammatory qualities can help reduce inflammation brought on by exercise, promoting recovery after your workout.
- Energy Creation: Since it's also needed to create ATP, the energy source for muscle cells, it helps provide the extra energy needed for post-workout muscle fiber repair.
- Protein Synthesis: Magnesium is a vital element to turning DNA and RNA into proteins, which heals damaged cells and aids muscle repair, recovery, and increased muscle mass.
- Electrolyte Replenishment: Heavy exercise can also cause electrolyte losses through sweat, especially with low magnesium intake. Increasing magnesium levels after exercise aids in reestablishing electrolyte balance, reducing cramps, and preserving healthy muscle function.
- Enhanced Circulation: Magnesium promotes proper blood flow, efficiently delivering nutrients and oxygen to muscle tissues. Increased circulation helps remove metabolic waste products, lowering the possibility of delayed onset muscular soreness (DOMS) and speeding up the healing process.
- Sleep: Magnesium also helps relax the nervous system to promote quality sleep, which is an essential part of the recovery process.
Here's what Reddit users have to say about the effectiveness of magnesium post-workout:
"So, a friend of mine suggested Magnesium supplements, and for me, it has been an absolute game changer when it comes to helping with DOMS from exercising.
I found when I reached mid 20s all of a sudden even light exercise would cause my muscles to get super sore and stiff to the point where I'd avoid exercise for days to weeks after even a mild exercise session. I tried everything I could think of- stretching before and after, incorporating hot yoga, ice, warm bath with salts, self massage, bengay... they all helped a bit but I was usually left being even less motivated with painfully sore and stiff leg muscles (especially calves.)
After taking magnesium, I rarely, if ever, get DOMS, and it's a manageable amount." (source)
"Replenishing my electrolytes (magnesium, potassium, sodium) after a tough workout day definitely seems to help me bounce back better too. I usually take 300mg magnesium citrate, 1 tsp of potassium salt substitute and 1 tsp of kosher salt and mix it all up in a blender bottle with Mio and sip on it for a few hours. It definitely helps curb my fatigue and soreness after doing a 10k." (source)
How Much Magnesium Do You Need For Optimal Workout Recovery?
