Natural vitamin D3 supplement for those who don’t get enough from food or the sun. Vitamin D is a superstar nutrient linked to many health benefits. What makes it so unique is that it’s a vitamin you can get through food and also a hormone your body makes from the sun. Despite the multiple ways of getting vitamin D, many are still deficient due to changing seasons, sunscreen, skin color, age, and sun protection. Get your daily dose of vitamin D3 by placing a drop of Super Daily® D3 in your food or drink. Each Super Daily® D3 drop provides 4,000 IU (100 mcg) of concentrated vitamin D.
