Magnesium citrate may be the most effective type if you want to try a supplement. If you're magnesium deficient, there may be other benefits from increasing your intake of this nutrient. And other remedies are available for leg cramping that may help.
A significant body of research has found that increasing your magnesium intake can help with the frequency of night time leg cramps, especially for pregnant women. Health experts recommend getting at least 300 milligrams of magnesium each day.
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.
Magnesium glycinate
Glycine is often used as a standalone dietary supplement to improve sleep and treat a variety of inflammatory conditions, including heart disease and diabetes ( 23 ). Magnesium glycinate is easily absorbed and may have calming properties.
Magnesium Glycinate taken before and after exercise may help relieve sore muscles.
Potassium. Potassium helps maintain normal cell function in the body, particularly in the nerves and muscles. It is relatively common for people to have a potassium deficiency. However, if a person has a severe deficiency , they may experience symptoms such as leg cramps.
Apply heat or cold.
Use a warm towel or heating pad on tense or tight muscles. Taking a warm bath or directing the stream of a hot shower onto the cramped muscle also can help. Alternatively, massaging the cramped muscle with ice may relieve pain.
Although further research is needed on magnesium and muscle cramps, taking 300 mg of magnesium daily may help decrease symptoms.
Meaning This trial suggests that magnesium oxide is not significantly better than placebo for alleviating nocturnal leg cramps. Importance Magnesium supplements are widely marketed for prophylaxis of nocturnal leg cramps (NLC) despite no evidence of significant benefit.
Magnesium citrate is a more common choice if you want to maintain magnesium levels for general whole-body health. On the other hand, magnesium glycinate has less bioavailability but can have a calming effect.
A 2015 study of the medical uses of magnesium recommends taking magnesium citrate because it's more easily absorbed by the body.
Most of the time, no apparent cause for night leg cramps can be identified. In general, night leg cramps are likely to be related to muscle fatigue and nerve problems. The risk of having night leg cramps increases with age. Pregnant women also have a higher likelihood of having night leg cramps.
There is a variety of factors that can lead to leg cramps. The most common causes of cramps include dehydration, muscle overuse and muscle strain or trauma. A common alternate cause is venous insufficiency.
Preventing leg cramps
If you often get leg cramps, regularly stretching the muscles in your lower legs may help prevent the cramps or reduce their frequency. You might find it useful to stretch your calves before you go to bed each night (see stretching advice above or try this post-exercise calf stretch).
As you age, your tendons naturally shorten and result in leg muscle cramps. These cramps are more likely to occur at night (in fact, 75% of reported leg cramps occur during this time) while you're trying to sleep and can make it quite challenging to rest.
Can a leg cramp be a sign of heart problems and/or a stroke? The answer is yes. Poor circulation in the legs' arteries can be a sign of poor circulation in heart arteries.
Orally, magnesium citrate is the best absorbed form (but it's bonded to a big molecule so there is a smaller amount of magnesium by weight). Mg oxide is the most poorly absorbed form but has the highest Mg per weight, so actually you may get more elemental magnesium out of the same dose of Mg oxide vs.
Magnesium glycinate/glycerophosphate - best for sleep and anxiety. Magnesium glycerophosphate is ideal for stress relief and sleep. Glycerophosphate has the lowest rate of diarrhea, as compared to other forms of magnesium.
Magnesium glycinate -- Magnesium glycinate (magnesium bound with glycine, a non-essential amino acid) is one of the most bioavailable and absorbable forms of magnesium, and also the least likely to induce diarrhea. It is the safest option for correcting a long-term deficiency.
