Leg cramps can stem from deficiencies in minerals like magnesium, potassium, sodium, and calcium, and certain vitamins, particularly Vitamin B12, Vitamin D, and sometimes B6, often alongside dehydration, all affecting muscle function and nerve signals. Imbalances in these key electrolytes are common culprits, especially with sweating or intense activity, but issues with vitamin D (affecting calcium) and B12 (nerve/muscle health) also play a role, with carnitine deficiency being a rarer cause.
Not getting enough of certain vitamins (e.g., vitamin B or vitamin D deficiency) or a lack of minerals (e.g., calcium, magnesium, potassium, phosphorous) can be leg cramp drivers. Some emerging research is looking at the potential role for vitamin K in easing leg cramps. Just getting older.
