Vitamin D Provides Health Support During Harsh Winter Months

Is also essential all year long

SALT LAKE CITY, Feb. 10, 2017 /PRNewswire/ -- During the winter months—when you are sheltered inside away from the sun—it is more vital than ever to get a daily dose of vitamin D. Getting adequate amounts of vitamin D helps support bone health, proper immune function and can even boost your mood.* While you absorb more sunlight in the warmer months, it is still essential to be conscious about how much vitamin D you receive no matter the time of year.

"Vitamin D plays a vital role in calcium absorption, keeping your bones strong and supporting your cardiovascular health and immune function. Unfortunately, too many people just don't get enough of it during the day," says Dr. Brian Dixon, USANA's executive director of health and science education. "It has been estimated that more than one billion people worldwide and 30-40% of the population between 15 and 49 years of age in the United States suffer from vitamin D deficiency. Even during the heart of summer, most people only get around 300 IU of vitamin D from the sun alone—no doubt due to their modern lifestyles. I strongly advise taking a daily vitamin D supplement not only during the winter, but all year round to ensure you are getting all the vitamin D your body needs."*

Experts vary on the daily recommended dose of vitamin D, but studies conducted by USANA Health Sciences suggest that approximately 4,000 IU/day is needed to get to and maintain a healthy level of vitamin D in your body. This can be achieved partially through diet with foods such as fatty fish like salmon, tuna, mackerel and sardines, specific types of mushrooms and dairy as well as responsible sun exposure. However, these are relatively small contributors, which is why experts recommend taking a daily vitamin D supplement as a safe and effective way to raise vitamin D levels.*

Combat deficiency now by going to and picking up your own maximum-strength vitamin D supplement.
