Review: High-Strength Vitamin D3 + K2 Supplement with Good Bone Support Potential - I’ve been taking the Dr. Berg Maximum Strength 2-in-1 Vitamin D3 K2 supplement, and overall I think it’s a solid product—especially if you’re specifically targeting vitamin D support along with bone and cardiovascular health. It provides a high dose of Vitamin D3 (10,000 IU) combined with Vitamin K2, which is important because K2 helps direct calcium to the bones rather than allowing it to build up in arteries. That combination is the main reason I chose this type of supplement instead of taking D3 alone. I do think it’s important to be careful with a high-dose product like this. Before starting, I had my vitamin D levels checked through blood work, and I would strongly recommend anyone else do the same. Vitamin D is one of those nutrients where more is not always better, and long-term overuse can lead to excessive levels if you’re not monitoring intake. In my case, I’m using it as part of a broader health routine focused on bone support and overall vitamin optimization, and it seems to fit well. Overall, this is a strong, high-potency supplement with a good D3 + K2 combination, but it should be used responsibly with attention to blood levels to avoid over-supplementation.
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, 
Dr. Berg Customer Care
