Review: Great Vitamin D with Potassium Supplements - Have been using about two weeks now and I’m so glad I got these-I was starting to have restless legs for the first time in my life and read up that this type of Vitamin D and Potassium should help. I noticed a decrease after about day 3-4, then much better by day 10 and will continue as needed to stave off that awful restless leg problem! Easy to take I swallow no problem and these help with much more too-great for vitamin D deficiency and great positive energy boost too.
Review: DR. BERG AND HIS AMAZING PRODUCTS ARE THE BEST - I have watched many of Dr. Berg's videos with great enthusiasm through the years and he has now become one of my favorite holistic media doctors. It is because of his lectures that I have purchased this amazing product. Dr. Berg emphasizes the importance of combining vitamin K2 with vitamin D3 in order for D3 to maximize the full range of its immune support functions. Dr. Berg also includes magnesium, zinc, the natural form of vitamin B6 (Pyridoxol 5 Phosphate) and other therapeutic compounds in his formula. These vitamins, minerals and compounds also all work together in order to promote the maximum immune support benefits of the sunshine vitamin D. Without these additional support vitamins, minerals and compounds (or if taken out of balance) your vitamin D absorption will be minimal and it will lessen its beneficial effects on your overall health. Research has shown that 35% of the United States population are deficient in vitamin D, while about 50% of the global population has vitamin D insufficiency. I, too, became aware of my own extreme deficiency in Vitamin D after a blood test revealed its devastating results. I now take two capsules of Dr. Berg's Vitamin D3 formula in the morning and again 2 more at night before retiring. It is advisable to consult with your doctor before beginning any kind of vitamin therapy - especially when determining the exact dosage of any vitamin or mineral supplement. I am so glad that that Dr. Berg came out with his own formula of vitamin D3 combined with other beneficial vitamins and minerals. Since I have trusted this doctor for many years I also trust his amazing formula of Vitamin D3. And, my current blood tests at my VA clinic show my vitamin D levels are now functioning optimally with positive results in my general health. If you are interested in delving deeper into the science behind combining vitamin D3 with vitamin K2 with its other complimentary vitamins and minerals, Dr. Eric Berg's videos can be found on YouTube. You might also find them helpful. I highly recommend Dr. Berg's formula of Maximum Vitamin D3 and K2 and give this amazing product 5 super big stars with happy faces. Buy it. You won't be disappointed.

## 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
