Effect of Vitamin D3 Supplementation on Cardiac Autonomic Nerve Function in Male Epileptic Patients With Hypovitaminosis D

The goal of this clinical trial is to see the effect of vitamin D3 supplementation on cardiac autonomic nerve function in male epileptic patients with hypovitaminosis D that weather vitamin D improves heart rate variability or not. The main questions it aims to answer are: 1. Does vitamin D improves cardiac autonomic tone in male epileptic patients? 2. Does vitamin D improves heart rate variability in male epileptic patients? It is a self control trial. Participants will: 1. undergo through baseline HRV testing 2. start to take vitamin D3 50000 IU once in a week for 8 weeks b) visit the university after 8 weeks for post interventional HRV testing . Researcher will compare the pre test and post test value of HRV testing.
