One of the implications of low levels of magnesium is muscle fatigue, muscle pain, spasms and cramps, and tension headaches.
Since magnesium plays a role in neuromuscular transmission and muscle contraction, it has been hypothesised that magnesium deficiency may predispose to muscle cramps. Thus magnesium supplements are often recommended to prevent cramps.
Having a magnesium deficiency can be a cause of muscle cramps. And it's common for people to need more magnesium. But, based on clinical studies, magnesium supplements have not proven to be an effective treatment for muscle cramps. There are still things you can do, with or without magnesium, to alleviate leg cramps.
Chronic magnesium deficiency is often associated with normal serum magnesium despite deficiency in cells and in bone; the response to oral supplementation is slow and may take up to 40 weeks to reach a steady state.
Refining or processing of food may deplete magnesium content by nearly 85%. Furthermore, cooking, especially boiling of magnesium-rich foods, will result in significant loss of magnesium. The processing and cooking of food may therefore explain the apparently high prevalence of low magnesium intake in many populations.
Magnesium begins to take effect after one week of consistent supplementation.
You can test your magnesium levels by purchasing a simple at-home finger prick test kit which is then analysed at an accredited lab. Forth offers a number of blood tests which include magnesium such as our Nutri-check test and Menopause Health blood test.
Humans with vitamin D deficiency exhibit muscle pain in muscles at multiple locations. However, the strongest association between vitamin D deficiency and pain is reported to occur in leg muscles (Heidari et al., 2010).
Although further research is needed on magnesium and muscle cramps, taking 300 mg of magnesium daily may help decrease symptoms.
1 Specifically in chronic pain magnesium can be helpful for offsetting the effects of calcium, which relaxes muscles and nerves. Magnesium acts like a plug in nerve receptors that are over-stimulated.
For muscles to contract properly, they need assistance from essential vitamins and minerals like Calcium, Magnesium, Iron, Phosphorus, Potassium, Sodium Chloride, and vitamins like Vitamin C, Vitamin B6, Vitamin D and Vitamin K. Each of these nutrients plays a significant role in healthy muscle contraction.
Vitamin B1 (Thiamine)
Vitamin B1 deficiency can cause heavy and tired legs after running, muscle cramps, fatigue, and odd sensations in your legs and feet. Some foods rich in vitamin B1 include whole grains, vegetables, legumes, milk products, and meat.
Most leg pain results from wear and tear, overuse, or injuries in joints or bones or in muscles, ligaments, tendons or other soft tissues. Some types of leg pain can be traced to problems in your lower spine. Leg pain can also be caused by blood clots, varicose veins or poor circulation.
Green leafy vegetables, wholegrains, nuts, seeds and legumes are great sources of this vital mineral. You may need to supplement with extra magnesium in tablet or powder form if your levels have dipped low.
Fruit juices such as orange juice, cherry juice, and watermelon juice are all good sources of magnesium, potassium, and phosphorus. According to the FNDDS, the average school container (124 grams) of 100% orange juice provides : 13.6 mg of magnesium.
In general rich sources of magnesium are greens, nuts, seeds, dry beans, whole grains, wheat germ, wheat and oat bran. The recommended dietary allowance for magnesium for adult men is 400-420 mg per day. The dietary allowance for adult women is 310-320 mg per day.
Therefore, magnesium supplements can be taken at any time of the day, as long as you're able to take them consistently. For some, taking supplements first thing in the morning may be easiest, while others may find that taking them with dinner or just before bed works well for them.
The claimed benefits of magnesium supplementation range from boosts in everyday wellness — better sleep, increased energy levels and improved mood — to specific health benefits, such as lower blood pressure, reduced risk of heart disease and improvement in migraines.
Magnesium supplements should be taken with meals. Taking magnesium supplements on an empty stomach may cause diarrhea.
Twitches, tremors, and muscle cramps are signs of magnesium deficiency. In worst-case scenarios, deficiency may even cause seizures or convulsions ( 1 , 3 ). Scientists believe these symptoms are caused by a greater flow of calcium into nerve cells, which overexcites or hyperstimulates the muscle nerves (4).
Mg is essential in the metabolism of vitamin D, and taking large doses of vitamin D can induce severe depletion of Mg. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy.
A blood test will be ordered to check your magnesium level. Normal range is 1.3 to 2.1 mEq/L (0.65 to 1.05 mmol/L). Other blood and urine tests that may be done include: Calcium blood test.
