Your Vitamin D3 level is too
You need to take Cholecalciferol preferably Sublingual along with Magnesium
and Vitamin K2 (if you don't have any Heart disease) to solve your Vitamin D3 deficiency which is the main cause behind your Leg pain
at night. Consult your Nutritionally informed Doctor for proper dosage.
Generally for such low Vitamin D3 in a person with 83 kg i.e above 150 pounds should take 20000 IU of Cholecalciferol daily along with Magnesium and Vitamin K2 for proper utilisation and absorption.
Best of luck. Vitamin D deficiency
