VITAMIN D’S NEWLY DISCOVERED FUNCTIONS

Do you think about vitamin D when you’re catching up on the sun’s rays outside? New, exciting research shows that this little powerhouse vitamin has many newly discovered functions. Of course, maintaining healthy vitamin D levels is essential throughout all stages of your life. But did you know that vitamin D receptors are found in countless tissues throughout the entire body? That can only mean that vitamin D has a much greater impact on the body’s health than we previously thought.

IMMUNE CELLS HAVE VITAMIN D RECEPTORS?

We already knew that vitamin D was very important in helping to maintain healthy bones, bone growth, bone mineralization and absorption of calcium. Vitamin D also supports cardiovascular system health.* But now, eye-opening research shows that our immune cells have vitamin D receptors. What? Immune cells with vitamin D receptors? Yes! This means that getting enough vitamin D may be critically important to support our immune system health by helping to activate immune cells.*

THE SUNSHINE VITAMIN

The body’s need for adequate vitamin D has gathered even more attention lately. Although direct sunlight exposure on the skin initiates an excellent source of vitamin D, many people simply can’t achieve the vitamin D levels they need for their best health. Maybe they simply don’t receive enough sunlight or it’s tough for them to convert vitamin D to the active form. Either way, taking a high quality vitamin D supplement makes good sense for supporting optimal health.*

WHAT SHOULD YOU LOOK FOR IN A VITAMIN D SUPPLEMENT?

First, the preferred form of vitamin D is D3 (not vitamin D2) because it is better metabolized by the body. Second, look for a natural source of vitamin D3 (not synthetic) with at least 5,000 IU per dose. Avoid products with undesirable chemical tagalongs such as magnesium stearate (a questionable excipient) or other chemical no-no’s.

Take 5 drops daily or as directed.
