My yearly physical turned up a deficiency in Vitamin D. Find out if you may have a deficiency too. It’s important for all of us to buy and take a high quality and potency multivitamin daily. Not a Centrum or One a Day, but one that has more value in it. I would recommend a visit to your local Vitamin Shoppe or GNC.
