## Questions & Answers

**Q: Is the liquid supposed to be milky? i opened mine and the liquid is white in color.**
A: Yes, the liquid is milky white and thick.  This is one of the most effective Vit D that I have ever used!

**Q: My bottle says 50 mcg, however it does not say 2000 iu? How do I know it contains that amount?**
A: 50 mcg = 2000 iu (in other words, it's the same thing)

**Q: Is this product still absorbed well seeing as it does not contain vitamin K2 like most vitamin D supplements do?**
A: On the whole, drops are better absorbed than tablets.  I take K2 and magnesium to help absorption concurrently with any D3....and with this specific product.  No D3 should stand alone for optimal absorption.  With this product, recommended by my doctor, I know that I am getting a high quality D3 with which I realize is best to not take alone for optimal absorption.

**Q: In the description it says it is vitamin d3, but on the bottle label it does not mention 
vitamin d3. is it d3?**
A: Yes it is d-3. Go to Biotics Research websie for more.
