## Questions & Answers

**Q: i need calcium with no D added . Does thie one is vitamine D free?**
A: It does not contain Vitamin D.

**Q: Can someone please tell me how long these pills are? I currently take 1200 mg in one pill and it is so large, it is hard to swallow. Thanks!**
A: Your body can only process 600 mg at a time. The rest washes out of the kidney & could damage them. You need to take no more than 600 mg in the am and 600 mg again in the pm.

**Q: Is this tablet coate?**
A: I don't know if it is coated, but it has a slightly shiny white surface.

**Q: i need to know the exact expiry date??**
A: Hello. That's a good question that I never thought about! On the bottom of the bottle there is a stamp. It says "LOT 12006600. Exp. 08/20. The date it was 
apparently stamped is listed as 11/08/17 12:12. 
Glad I could help you, and educate myself!
