Review: Great Experience with Dr. Eric Berg Vitamin D - I’ve had a positive experience with Dr. Eric Berg Vitamin D. It seems to reduce my joint pain and inflammation, and I’ve been getting sick less frequently, which may indicate improved immune support. I will repurchase.
Review: Great and necessary Vitamin. - Amazing med, I have a low D problem so it’s a must have for me. I didn’t realize how important the K part works until I listened to Dr Berg on Facebook. I do notice a little less joint pain. Over Christmas I had a friend visiting, he’s a big guy post stomach staple surgery. He was acting like a jerk, very irritable and anxious. I’m a nurse so I started him on these pills and gave him a bottle to take home. When he followed up with his doctor he indeed have a very low vitamin D issue. His doctor gave him a script until his levels are better but want him to continue on these after. He is up to normal.

## Questions & Answers

**Q: Can anyone confirm that newer bottles of this d3/k2 no longer contain the "red yeast rice" that has been a little controversial in dr berg's formula?**
A: I have the same question.  Dr. Berg's video announcing removal of red yeast debuted on April 11, 2018.  Thus, it's not clear how much of the product currently has red yeast.
https://www.youtube.com/watch?v=qGwDTixHCZg&feature=youtu.be

**Q: It shows 1250% vitamin D3. On one of his videos he says anything at that level is most likely synthetic. What gives?**
A: Because it's not the % of the vitamin/ mineral as much as it's the amount. If you have a natural source food and it had that much it's not real but this is a supplement ( extracted from food to be in high concentration) so it is not what you would get in a food unless it was fortified like yeast and the b vitamins if you see a yeast product with b12 in high amounts it has been fortified like cereal

**Q: What is the difference between menquinone-7 (dr. berg's formula) & menaquinone-7? (all other vitamin k2 products)? see the difference in spelling?**
A: IDK .. my objections to Dr B'z products are only related to EXCESSIVE shipping charges

**Q: is it gluten free ?**
A: Hi Divra, 

Our Vitamin D3 and K2 Supplement contains vegetarian capsule and it's gluten free. 

I hope that helps. 

Best,
