Review: D3/K2 Power House! - Dang! I had no idea how much I needed this until I started taking it! I've listened to a lot of Dr. Bergs podcasts and he very often talks about the importance of D3 and coupling it with K2, which he says is essential to properly absorb the D3. I've found that to be true for me. Since I started taking this supplement, I haven't gotten sick in I don't know how long (at least a couple years) and it makes sense because apparently D3 helps super-boost your immune system. Other things I've noticed are that my sleep is better, I feel less tired and sluggish throughout the day and I feel less inflamed. These are just small capsules and you take 2 of them per day. Super easy to swallow and they don't have a taste. I don't notice any stomach trouble from taking them either. If you're like me and you spend the majority if your day inside (which means less sun and therefore less D3), this stuff will rock your world! 5 stars, worth the price and highly recommended!
Review: Follow the symptoms, ALWAYS! - You ever have symptoms that you know aren't normal despite a doctor telling you that you have no std's and your blood work came back clean with no hiv? I never considered that i may have an autoimmune disease despite my doctors always saying i'm healthy. The thing about autoimmune (not sure about all of them just the one autoimmune that has all of my symptoms down to the letter) is you begin to build a vitamin d resistance and higher iu's are required in order to get the therapeutic effect. Once i bumped up to 160,000 iu's per day of Dr. Berg's Vitamin D3 K2 I noticed my symptoms began to ease up and with each passing month of consecutive use and today of dedicated use I feel as if I am in complete remission. Granted I also took Dr. Berg's advice on keto carnivore diet and elimination sugars. My main symptom that caused me misery was how quickly i would dehydrate in a day. I would curse at my own saliva glands for not doing what i needed them to do. I now produce a healthy saliva flow and after a year am starting to notice that not only is my tongue repairing itself but other problems are being resolved. I am not speaking for anyone else. This is literally what is happening with me. So why option Dr. Berg's version of the d3k2 iu? Quite simple, you cannot just take vitamin d on its own. You can do yourself true harm by taking just vitamin d on its own. Vitamin d needs k2 and magnesium etc in order to properly absorb. Taking vitamin d on its own is useless garnishing you a very low absorption percentage. Almost next to none. Most companies know this but push out poor cheap products anyway. Dr. Berg never uses synthetics and makes sure the D3 is combined with the proper vitamins and minerals so that you properly absorb and avoid building any deficiencies elsewhere. My only complaint is Dr. Berg needs to produce a 50k-100k iu d3k2 product for those of use who safely require a higher dosage. Thank you, doc for everything!

## 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,

### ⭐⭐⭐⭐⭐ Real results that has changed my life
*by S***D on July 4, 2026*

This product has impacted my life so much. Increased energy levels, I notice significant improvement of symptoms such as burning and tingling of my feet, as a matter of fact this has not improved, it's gone all together. I am mentally sharper, very grateful for how much it builds up my immune system . I hardly ever get sick but when I do come down with a cold or something, my immune system is a beast. I recover quickly. After using this product for nearly a year I have since introduced it to my family members, my mom and my brother in particular are regular customers now. Help for whatever you need in a capsule!!!
