How do I know if I need to supplement with vitamin D?Updated a year ago

 Your personal healthcare professional can order a simple blood test to check your vitamin D levels. You may be at risk if you: • Experience less than 15-30 minutes of full body exposure sunlight between 10 a.m. and 3 p.m. • Wear sunscreen. • Have a darker hue of skin color. • Are over 65 years of age. • Spend most of your time indoors. • Live in a region with a long winter season. • Are overweight or obese.
