I remember purchasing for Mother a chewable source of vitamin D. She treated it like candy and gave some to one of her granddaughters. I was so angry! Mother believed she was getting all the vitamin D she needed from fortified powdered milk.
Our body’s ability to convert sunlight into active vitamin D declines as we get older. In the winter, sunlight lacks the UV rays that make vitamin D unless one lives as far south as Atlanta or Los Angeles. That and the fact that few foods are rich in vitamin D means that many people have less-than-optimal blood levels.
The Institute of Medicine recommends 600 IU a day of vitamin D for adults up to age 70 and 800 IU for those over 70. Most multivitamins have at least 400 IU.
When it comes to a multivitamin, I like Special One from Now Foods. I purchase this product at www.iherb.com. Use this coupon code, BER298, and save $5.00 at checkout.
Scientists are still investigating whether vitamin D may lower the risk of cancer, heart disease, stroke, diabetes, memory loss, depression, and more.
