What Supplements Help Leg Cramps

Studies have shown that a deficiency of particular vitamins and minerals causes cramping and muscle pain – Reasons for Leg Cramps

Popular vitamin and mineral supplements described in this article found from consumer reviews and medical articles are Vitamin B1, Magnesium, Vitamin D and Potassium. Recommended dosage is 1 tablet a day or as recommended by your doctor.

Other topical relief products are discussed in another article.

Vitamin B1

Thiamine (vitamin B1) is a water-soluble vitamin that helps us digest and extract energy from food to create useable energy to assist with metabolism. It also plays an important role in the production of red blood cells.

Because the body cannot produce thiamine, we must get it from the foods we eat to prevent a deficiency.

It is therefore understandable that a deficiency of this vitamin could cause muscle cramps and leg pain after running as the muscles seek to quickly create energy for their oxygen -low cells.

Other signs of a deficiency of vitamin B1 are weakness of muscles, muscle wasting and pain and stiffness in the legs.

Food like vegetables, meat products, and legumes are rich in Vitamin B1. Supplements help to increase the intake of vitamin B1. Check out other function of B1 in vitamin B complex.

Magnesium is widely used to treat leg cramps, especially in Latin America and Europe. But many clinical studies of magnesium treatment for cramps found it to be ineffective (Healthline) although some people insist it works.

The Best Magnesium Supplements for You

Keep in mind that there could be several reasons for leg cramps. You might possibly be low in some other nutrient.

For example, there is an inter-related relationship between magnesium, calcium and potassium which are both also involved in muscle cramping (Healthline).

If low levels or a deficiency of one of these is present, it is unlikely that magnesium would help.

On the other hand, magnesium does help some people.

A high intake of magnesium in the diet lessens leg cramps at night. Doctors suggest taking at least 300-milligram magnesium daily.

Nuts, lentils, and quinoa are rich in magnesium. But they fulfill the need slowly. So, if you want to speed up the process, you may wish to switch to magnesium supplements for leg cramps.

Doctors have claimed that intake of this vitamin improves leg cramps and muscle pain. As we all know, milk and yogurt are good sources of vitamin D.
