D3&K2 Vitamin

Why does Dr. Berg recommend 10,000 IU of vitamin D?

There seems to be a lot of confusion surrounding vitamin D3. Most people take 600 IU to 2,000 IU of vitamin D3 and they think that’s enough. But is it?

About 75% of the population on Earth is deficient in vitamin D. Dr. Berg believes that vitamin D is the most important fat-soluble vitamin – especially for the immune system.

Studies on vitamin D:

In one study, the group took 1,000 to 2,000 IU of vitamin D 1 to 2 times per week for 1 month and it did not increase their vitamin D levels at all.

In the second study, the group took 1,000 to 2,000 IU of vitamin D and it took 4 months to elevate their vitamin D.

In the third study, it took 3 months to achieve the normal level of vitamin D by taking 1,600 IU of vitamin D.

Two important lessons that could be extracted from these:

  • It takes a lot longer than you think to fix a vitamin D deficiency

  • There are various things that prevent the absorption of vitamin D

Things that can prevent the absorption of vitamin D:

  • Gut damage

  • Age

  • Skin pigment

  • Subcutaneous fat

  • Sun exposure

  • Metabolic issues

  • Season

  • Polymorphism

  • Chronic infection

You may want to consider taking 10,000 IU of vitamin D per day for maintenance, but could take more if there is an autoimmune issue involved.

You would have to consume something like 100,000 to 200,000 IU of vitamin D for months or years to create complications. The biggest complication of vitamin D toxicity could be hypercalcemia.

Still, to help minimize the risk of hypercalcemia, you could drink 2.5 liters of water per day. You could also simply avoid consuming calcium in supplements as well as in cheese.
