Nighttime leg/foot cramps.
Indicates magnesium deficiency. Our body needs up to 400mg magnesium per day for 300+ activities within the body. Some of the 400 mg comes from your food. Magnesium is stored in your bones, and when you reach your body's appropriate level, your leg and foot cramps will cease. It could take several days or weeks to reach that point. Be patient.
A) Supplement morning and night with quality tablet or capsule of Magnesium Glycinate. Gentle on your system, no stomach or digestive tract upset. Reasonable price at Health Food stores.
And/or soak your feet for 15 mins, every 3rd day, morning or evening in Hot (NOT Scalding Hot) water with a 1/2 cup of "Epsom Salts" (Magnesium Sulphate)( Disssolves immediately). Feet and legs will likely pleasantly tingle while you are soaking.. "Epsom Salts" in 2 Kg jug available from Walmart and ShoppersDrug Mart for $9.99 CAD
Works great for me.
