Year-Round Vitamin D Intake

Vitamin D is known as the sunshine vitamin because it can be synthesized by your body through exposure to sunlight. Unfortunately, it isn't as easy as taking a walk in the park. According to a new study published in the Journal of the American Academy of Dermatology, getting enough sunlight to cover your daily needs isn't always an option.

Researchers created a computer model to determine how much daily sun exposure a person would need to synthesize 400 IU of vitamin D. They did calculations for January, April, July and October in two major American cities: Boston and Miami. You'd be able to produce 400 IU of vitamin D in 3 to 6 minutes pretty much any day if you lived in the Sunshine State. But you'd be hard-pressed to get your needs met during a typical Boston winter.

True Strength Moment: There's an ongoing debate about how much if any direct exposure to sunlight is safe. You can very easily remove yourself from this debate by talking a high-potency multivitamin that helps you cover your recommended Daily Value for Vitamin D. This nutritional insurance is particularly useful to those living in the northern latitudes during the cold, gray months.

Great to know this! I live in FL, but still take a Vit-D daily in addition to my multi. :)
