If you’re one of the approximately 75% of Americans who are deficient in vitamin D, look no further. Doctor’s Best Vitamin D3 is a “sunshine vitamin” needed to maintain strong bones and teeth and provide optimal immune function.* If you are not spending a lot of time in the sun or eating certain foods like fatty fish, fortified milk or eggs, you’re likely deficient in vitamin D.
