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.

Man needs to keep his bones solid like a brick phone from 1998, and dis little capsule be doin’ the business.First off, it got 5000 IU of D3, which is bare sunlight in a pill, safe? Perfect for when man been indoors all winter playin’ PlayStation instead of catchin’ rays. And den you got the K2, which is like the hype man for the D3 — makin’ sure all dat calcium go to the bones and not floatin’ around your bloodstream like it owns the place.They say it’s 4X lab-tested, which means proper scientists in white coats checked it more times than I checked my reflection before leavin’ the yard. High-absorption formula too — goes into your system quicker than a rumor on WhatsApp.Capsules is small, easy to swallow, no funky aftertaste. Nuff respect for that. Man don’t want vitamins tastin’ like gravel.If you tryin’ to keep your bones strong, immune system tidy, and overall vibe well solid, dis supplement is straight-up wicked. Safe for anyone wantin’ to level up their health game without doin’ nuffin’ complicated.

A healthy dog again .
I did not believe my dog could live another year because her health had deteriorated so much that I was thinking maybe she was finally finished. She no longer could see or hear and had continued having bouts of diarrhea. I had to hand feed her every day. By the way she is going to be 17 years old. I saw this presentation on the net by Dr Berg about how dogs were being made sick from eating over processed dog food. I definitely thought it was worth a try . In one week she started eating and drinking water on her own. I no longer had to hand feed her and her stools were normal. Now after a month she now is running up and down hallways in the house at full speed. Of coarse she still can’t see very good but she has stopped walking into walls and doors. Maybe 20 years old is going to be possible? Thank you Dr Berg

Higher dose of vitamin D in the bigger bottle
Love Dr. Berg and his products. My only issue is that opted to buy the bigger bottle but it also comes in 10,000 iu of vitamin D. The smaller bottle is 5,000 iu of vitamin D. I take several other supplements including the magnesium by Dr. Berg and it also has vitamin D. So if I want to get my K2 in that I bought with this supplement, I can’t take my magnesium, several other supplements because 10,000 iu of vitD is the limit anyone should take.

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
Amazon Customer –
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.
