It’s the Best!
I won’t use any other Vitamin D! My Vitamin D level was so low and I started taking this and in a short period of time my numbers were perfect! I trust the quality of your products and they make me feel really good! Wouldn’t buy them anywhere else!
Excellent product - I recommend it
I was very satisfied with the Optimum DK I wish I could continue getting it from you but unfortunately Canadian restrictions won’t allow it to be imported by me
Def recommend this product. It has brought up my low levels in about 3 mths.
I have been using this formula for a couple years. My doctor likes the fact that it contains Vitamin K, along with the Vitamin D.
