The following are all causes of leg cramps: poor circulation, atherosclerosis (blocked blood flow in the arteries), not exercising enough or over-exercising, deficiency of certain minerals, imbalance of electrolytes, dehydration, certain medication (diuretics, cholesterol-lowering medication), nerve damage (found in diabetics), leg injury (torn or overstretched muscle), unaccustomed physical exhaustion, sitting, standing or lying for too long and varicose veins. It is important to take a calcium supplement, especially females, as we are more prone to getting osteoporosis. Its the type of calcium you take that is important for absorption. Calcium from Dolomite is high in lead and not easily absorbed. The best forms of calcium to take is Calcium Citrate, as well as Chelated calcium and all calcium should be taken at night before bedtime. SuperCal (from Good Health) is a really good calcium-magnesium supplement, as well as Foodstate’s calcium & magnesium formula and Enzyme Process Super-Cal-Mag. A good powder form would be Viridian’s calcium, magnesium and boron formula. Magnesium is needed for muscle contraction and relaxation. Potassium is needed for proper metabolism of calcium and magnesium and it aids in relieving muscle cramps. Zinc is needed for the absorption of calcium. Viridian’s Balanced Zinc Complex or Zinplex are good products to use. Taking a vitamin B complex will improve circulation and cellular function. Vitamin E also improves circulation and a lack of this vitamin can lead to muscle cramps specifically in the legs. Sleeping with your legs slightly elevated so that it is at a level higher than your heart, will help ease cramps. Massage your legs with unprocessed olive or flaxseed oil before going to bed or before any strenuous exercise. Always stretch your muscles before and after exercise and….Drink sufficient water to prevent dehydration.
