Feel the Difference a Spoonful of LIQUID SUNSHINE Can Make. Just a spoonful of delicious, tropical citrus-flavored Liquid Sunshine provides 5000 IU of vitamin D3, nature's most bioavailable form. Studies indicate that 5000 IU of vitamin D3 every day can help many people achieve optimal calcium absorption and support healthy bone density. Yet, according to the National Center for Health Statistics, more than 35% of Americans don't even get the minimum Daily Value (DV) of 400 IU that only serves to prevent deficiency. And recent research shows that if you're only getting the Daily Value, you're probably not getting enough for optimal health. Liquid Sunshine Vitamin D3 5000 IU goes beyond the limit activity of 400 IU by providing the superior health benefits that can only be found at such high-potency levels
