FAQs

How do I know if I need to supplement with vitamin D?

Your personal health care 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 am and 3 pm.
• 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.

I didn’t realize vitamin D had immune system benefits. How exactly does vitamin D work to support my immune system health?

Researchers have found vitamin D receptors on most immune cells suggesting a significant role for vitamin D in the immune system. In fact, when we're not getting enough vitamin D, our immune system may not to function at its best. That’s why we recommend having your vitamin D level tested with your health care professional so that they can help you decide on the vitamin D product that is right for you.

What is the difference between your liquid softgel vitamin D and your tablet form of vitamin D?

As long as the dosages are the same, there is no difference between the two forms. Some people prefer the liquid softgels over the tablets believing that they are easier to swallow, but it is a personal preference.
