- Dr. Berg Maximum Strength 2-in-1 Vitamin D3 K2 10,000 IU | Naturally Derived D3 | 4X Lab-Tested & Verified | High Absorption Formula | K2 D3 Vitamin Supplement - 120 Capsules

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.

I've been following Dr. Berg for many years now. Dr. Berg's supplements are known for their high quality and often stand out compared to other options on the market. They are formulated with a focus on premium ingredients and effective delivery to support overall wellness.

Another excellent product from Dr Berg. A little pricey but well worth it. His products have all the nutrients we expect. Our hair and nails grow like crazy. I have to file my nails daily because of new growth!

This is a great product. VITAMIN D/K2 Dr said my vitamin D levels were good.

Dr. Berg makes high quality products and does his research well.

This is an excellent combination supplement. A lot of people can be deficient in vitamin D and don't realize it is best absorbed with K2. This supplement has both in one pill. The pill is medium I would say for a supplement. It is easy to swallow as it is not very thick. Serving size is one capsule and you get 50 so almost a two month supply which is great for the price. There is no strange odors or tastes making it easy to take each day.

Been using this for several months and love it! Have had no issues or side effects at all. Have noticed an increase in my energy while using Dr Berg’s Vitamin D3/K2

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.

I like this combined vitamin very much. First, 10.000 IU vit D3 per capsule (I never take a capsule but drop the powder in water and drink) and then the additional K2 you need as well. I take it now every day and feel the difference already.

Upto Expectations

must try

Good Quality, I bought this for a friend of mine who came out of a very hard disease and she's taking this supplement daily and is so happy with it, also very fast delivery

my 1st purchase was on January 2025 and I feel significant healthier than before regarding my knee pain and overall ...I used to get this "insufficient level" result of Vit D before I consumed this. Then after 4 months consuming Dr.Berg Vit D3 10000iu +K2 , I had my Vit D level checked again and the result showed "sufficient level" on May 2025. I'm happy that this supplement actually works. For maintenance I consume 5000iu now.
