Did you know Vitamin D3 with K2 supplement plays 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. The good news is you can simply take one capsule of Dr. Z’s Vitamin D3 with K2 and reap the amazing health benefits of these two 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’ s 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.
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 Should You 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 for the 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 then 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 adults, 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. However, you can easily overcome these deficiencies by taking a Vitamin D3 K2 dietary supplement.*
