Did you know vitamin D3 with k2 supplement play a key role in our health? This is why?
Most Americans – and people all around the world – are low in these important vitamins, thanks to our modern lifestyle. But the good news is you can simply take one capsule of Dr. Z’s Vitamin D3 with K2 and reap amazing health benefits of these remarkable vitamins.
For years, Dr. Z’s Vitamin D3 with K2 was available only to his patients. Dr. Zaidi saw these patients on a regular basis and carefully monitored them for any side-effects. At the same time, vitamin D level was tested – at baseline, then periodically at about 3-6 months intervals.
Thousand of patients received Dr. Z’ Vitamin D3 with K2 over a period of fifteen years. It was found to be effective in raising vitamin D level into the normal range in the vast majority of patients. At the same time, no side-effects were noted.*
Meanwhile, Dr. Zaidi observed some amazing health benefits in his patients.* He shares these clinical findings in his well-acclaimed book, “Power of Vitamin D” , which was first published in 2010. At that time most people – and physicians – were not even aware of the benefits of vitamin D.
So, What Is Vitamin D3 With K2 Supplement good For?
Tons of scientific studies suggest that vitamin D3 K2 may support:
- Immune system*
- Bones and joints*
- Cardiovascular system*
- Blood sugar levels*
- Healthy mood*
For scientific studies, please refer to Dr. Zaidi’s book, “Power Of Vitamin D”
Each small easy-to-swallow capsule of Vitamin D3 with K2 supplement contains:
Vitamin D3 = 5000 IU ( 125 mcg)
Vitamin K2 (as MK7) = 100 MCG
One capsule daily preferably with a meal or as recommended by a healthcare professional.*
Why you should take Vitamin D3 and K2 together?
- Numerous studies show that vitamin D3 and vitamin K2 amplify each other’s action (1).
- Using vitamin D3 alone may increase your risk of calcium deposition in the arterial walls. This is where vitamin K – especially K2 – can be very helpful as it can prevent tissue calcification.
For these reasons, it makes perfect sense to take D3 and K2 together.
D3 versus D2
Vitamin D3 is the one that our body produces when we are out in the sun. On the other hand, vitamin D2 is what plants produce. That’s why Dr. Z’s Vitamin D3 with K2 contains D3 and not D2.
MK4 versus MK7
Vitamin K2 exists primarily in two forms: MK4 and MK7. These two forms differ in their duration of activity. MK4 has a shorter duration while MK7 has a longer duration of activity. Therefore, MK4 supplement has to be taken two to three times a day. Whereas MK7 supplement can be taken only once a day. For this reason, Dr. Z’s Vitamin D3 with K2 contains MK7 and not MK4.
How much Vitamin D3 and K2 to take?
The NIH (National Institutes of Health) recommends a daily dose of Vitamin D to be 400-800 IU per day (2). While this dose may help your bones, most experts believe it is too small of a dose for the other health benefits such as immune system and cardiovascular health. For example, the Endocrine Society – a prestigious organization of endocrinologists – recommends a daily dose of 6000–10,000 IU to raise vitamin D level above 30 ng/ml (3). A level below 30 ng/ml is considered low.
Vitamin D is Fat-soluble
As vitamin D is fat-soluble, its dose really depends on your weight. Because the more fat you have, the more vitamin D gets trapped in it. And less is available for the rest of the body. Therefore, Dr. Zaidi recommends a daily dose of 5000 – 10, 000 IU if you weigh between 100 to 200 Lbs.*
How Much Vitamin D for Children?
Experts recommend a daily dose of vitamin D3 as 1000 IU per 20 Lbs. body weight. For example, a child weighing about 40 Lbs. needs about 2000 IU of Vitamin D3 per day.*
How Much Vitamin D for Cold, Flu, and COVID?
For cold, flu, and COVID, medical experts recommend Vitamin D3 as 15,000 to 30,000 IU per day if you weigh between 100-300 Lbs.* Take this high dose of vitamin D for cold, flu, and COVID only for a few days. Then, go back to your daily maintenance dose. There is no risk of vitamin D toxicity for a short term use of high doses of vitamin D3.
How Much Vitamin D for a Healthy Heart?
For grown-ups, experts recommend a daily dose of vitamin D3 as 10,000 IU – along with 200 mcg of Vitamin K2 – to support a healthy heart.*
How Much Vitamin D To Prevent Cancer?
For adults, a dose of vitamin D3 as 10,000 IU – along with 200 mcg of Vitamin K2 – is considered adequate for the prevention of cancer.*
How Much Vitamin D To Prevent Osteoporosis
As an adult, you need only a small daily dose of vitamin D3 (1000 IU) and K2 (200 mcg) to keep your bones strong and healthy.*
How Much Vitamin D for Autoimmune Disorders?
You need a high dose of vitamin D for autoimmune disorders such as asthma, rheumatoid arthritis, Hashimoto’s thyroiditis, Graves’ disease, lupus, Crohn’s disease, ulcerative colitis etc. Experts recommend a daily dose of 10,000 – 30,000 IU of vitamin D3 if you weigh between 100-300 Lbs.*
No established dose of Vitamin K2
There is no established dose when it comes to vitamin K2. Usually a dose of about 200 microgram (MCG) is used in dietary supplements. This dose of vitamin K2 is based on a study from the Netherlands, in which researchers used a daily dose of 180 microgram of MK7 in postmenopausal women for 3 years. At this small dose MK7 prevented age-related decline in bone mineral density (4).
What are the side-effects of Vitamin D3 and K2 ?
Side effects from Vitamin D3 and vitamin K2 are exceedingly rare!
However, you can develop Vitamin D toxicity if you take very large amounts of Vitamin D – more than 80,000 IU per day – for several weeks.
Vitamins D3 and K2 are important for our optimal health. However, a deficiency of these vitamins is common – thanks to our modern lifestyle. But you can easily overcome these deficiencies by taking a vitamin D3 K2 dietary supplement.*

Robin B. –
Have tried many other versions of Vitamin D and K2 from trusted sources for 7 years when I was UNdiagnosed. My test results barely budged. When I finally was diagnosed with Graves Disease I started reading Dr. Z’s book on Graves Disease and tried his version of D. Have never looked back. My D test results doubled and I am finally in a better than traditional “healthy” range, but safely in the Dr. Z range. I cannot thank him enough for both his book and the quality of his Vitamin D. I have been in remission for 3 years now and hope (like the reviewer above) to continue into the future. I will be on his D as long as he continues to make it. I am so thrilled with this product, I buy extras to give to friends whose health is challenged. I say it’s the best Vitamin D on the market and believe it with all my heart. Thank you so much!
I started taking Dr. Zaidi’s vitamins over 10 years ago. I stopped when I moved to the East Coast and immediately saw a difference in my health and overall well-being. I started the regimen again soon after and everything from my mood to my health improved drastically. I now order online and I cannot recommend his products enough! His books are also amazing and I have followed his dietary recommendations for Grave’s Disease. Since Dr. Zaidi took over my care I have been in remission over 10 years now.
