## Questions & Answers

**Q: Is this product (vit d3 - chlolecalciferol) actually 5000 iu?   information  leads me to believe otherwise.  confirmation would be greatly appreciated**
A: I can confirm the strength is as advertised - Formula: 1 ug = 40 IU / 125ug x 40 = 5000

**Q: 60mg each tablet.??.
mg = milligrams (NOT micrograms). 
Clearly you have a serious labelling error here.  
micrograms = mcg or ug**
A: Avoid this brand the doses dont make sense.

**Q: Please can you clarify. Your packaging is wrong.  You state 60mg = 5000iu but 60mg using the formula 1mcg=40iu means that yr tablets are 2,400,000iu.**
A: It says NRV2.500 amount per serving 60mg providing 5000iu  vitamin D 365 tablet's

**Q: Does this product contain silicon dioxide?**
A: Hi, I hope you are well. I can confirm this product does not contain silicon dioxide. Warmest regards
