I just started taking the H37 vitamins and notice I have been getting a slight headache at lunchtime mostly after I take the dosage required with a meal. I called the company and they said they have no reports of this problem. Has anyone experience this? I am thinking this is just new to my system(body) and it will soon be over. I have been taking them for about two weeks now. Let me know what you think. I hope Southerngirl sees this I know she had good results with this product.
