Doctor’s Best Vitamin D3 supports healthy bone density and structure as it is required for optimal calcium absorption. More than that‚ this nutrient enhances and regulates immune function‚ supports optimal cardiovascular function and enhances cellular function. It is made of D3‚ the naturally-occurring form of vitamin D. Research shows that supplemental vitamin D3 (cholecalciferol) is significantly more efficient at converting to active vitamin D in the body than vitamin D2 (ergocalciferol). This makes vitamin D3 the preferred supplemental form of this nutrient. Vitamin D deficiency is prevalent with more than 75% of Americans deficient in this nutrient. People who live in the northern half of the United States are at a greater risk of being Vitamin D deficient due to a lack of sunlight.

      I never get the flu

      from Pensacola Florida on 4/17/2020
      Since taking D-3 along with zinc and my green drink, I haven't caught a cold or flu in about 5 years. If I feel a cold trying to take hold, I up my Vitamin D-3 . D-3 is my flu shot. I don't dread the winter anymore, knowing I won't catch the flu/cold. 

      Pros

      It works!

      Cons

      Nothing.
