Dr. Berg Vitamin D3 & K2 10,000 IU + MK-7 – 120 Capsules – Immune, Bone & Heart Support* Supplement w/Magnesium, Zinc, B6 – 4X Lab-Tested – No Fillers – Non-GMO, cGMP, Formulated in USA

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’ve been using this product for 1 yr & had great results paired with magnesium by Dr. Berg. No cramps, good sleep! I’ve recommended this to performance cyclists & they’ve also gone from a serious reduction in cramps and better performance. It’s my go brand and product.

Best vitamin D3+K2. It improves my daily mood and energy level. The capsules are small. They are easy to swallow and never get stuck on my tongue. I highly recommend this vitamin. I absolutely love it.

This is a wonderful supplement! It works and helps as advertised. I have used this for a couple of months and it does make a difference. Thank you, Dr. Berg

Hoping to improve bone density calcium levels. We will see if this works since I haven’t had blood work but they are easy to swallow and so happy it’s just one a day.

Love Dr. Berg's products. Very informative. No stomach issues. Good size pill to swallow. Worth the money.

This product is actually amazing. Around summer of 2024 I decided I needed to take control of my nutrition and vitamin intake, so I started with Vitamin D and a multi vitamin, and I had my D levels tested. They were in the toilet at like 30 ng/mL. I started with Amazon Basics 2000IU daily, but then switched to the dr Berg 10k IU about 6 months ago. My levels are now 79 ng/mL as of 1/20/26. This might also be TMI, but I always used to have IBS type issues and after the Vitamin D supplements and getting my levels back on track, I do not have bathroom issues anymore, like ever. Unless I eat something REALLY fatty or greasy. I think I am going to back off to a 3000 IU daily now just to maintain, and have my levels checked again next year.

I watch Dr. Berg's videos all the time on healthy lifestyle. He is the most knowledgeable doctor on natural food, supplements, exercise tips and more. These vitamins are excellent. I have more energy taking one vitamin pill a day with my breakfast. I digest them very easily. I highly recommend these vitamins to supplement vitamins D3 and K2 to your daily routine. Thank you Dr. Berg. Love all your supplements.

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.
