Left side leg cramps/tingling numbness are a calcium deficiency, right side is magesium. B1 def. causes calf tenderness, and can cause burning feet and hands, zaps and tingles, or swollen face, among many other things. Grouchy, aggitated, or agressive moods can be caused by all three. They all help the nervous system. It is very possible you have a magnesium, calcium, or b complex deficiency.
ps...someone on mamasource just asked asked this question the other day. You should go look at her responses.
If I were you i would supplement all three.
Dimagnesium malate is a chelated form- your body recongnizes as food. take ###-###-####mg. High levels of protien encourage magnesium absorption.
Calcium, use calcium carbonate or citrate with meals. High levels of caffeine/protien/sodium encourage the body to release calcium. Taking potassium at the same time can help with uptake, as can taking cod liver oil (for the D). Don't take magnesium and calcium at the same time- they compete. However, they do need work together to regulate nerves and nuscles. Just take them at different times.
Take your vit B as a B COMPLEX. Probably everyone should take b vits- we don't store b and our diets destroy them.
