Summary

Vitamin D deficiency is not always easy to detect. Blood tests do not reflect what's going on deeper in your cells.

Taking too much vitamin D can be dangerous if you have hypercalcemia, or too much calcium in the blood. This can lead to kidney stones.

A lack of vitamin D is also dangerous! If you’re deficient in vitamin D, you are more susceptible to autoimmune diseases, which is currently the world’s largest health problem.

Vitamin D is involved in over 2500 genes and is intimately involved in every part of your immune system. You need a maintenance dose of 8,000 to 10,000 IU of vitamin D daily for healthy immune function.

Many people can not get adequate vitamin D from the sun or their food. Genetic factors can contribute to vitamin D resistance. Low magnesium, zinc, and vitamin K2 can also inhibit the absorption of vitamin D. Certain viruses downgrade vitamin D receptors, weakening your immune function. Our RDAs are also far too low.

There are several ways to maximize vitamin D benefits while also preventing adverse vitamin D side effects. Take the cofactors magnesium, zinc, and vitamin K2 with vitamin D. Limit your calcium intake, especially when taking a high dose of vitamin D. You can also increase fluid intake to 2.5 liters per day to prevent kidney stones.

0:00.0	Hello, Dr. Berg here.
0:01.3	And today we're going to talk about the number one vitamin D danger that you absolutely
0:06.7	positively must know more about.
0:09.3	A lot of the research that I'm talking about is based on Dr. Coembre from Brazil, who studied
0:14.8	autoimmune diseases for quite some time.
0:17.0	And he has the Coimbre protocol where he uses a lot of vitamin D. For some people,
0:21.9	could range between 60,000 IUs per day, up to 200,000 IUs of vitamin D3 every day to penetrate
0:31.3	through this resistance and to create the effect to put these autoimmune conditions back
0:37.1	in remission. And his success level
0:39.4	is like over 90%. If you look at your vitamin D levels and you're assuming like, oh yeah, my
0:44.4	levels are fine because my blood levels are fine, don't assume that's really what's going on deeper
0:50.9	in the cells. There is some better ways to know if vitamin D is working. I am going
0:54.7	to get to that. But the blood level only gives you a little bit of information. Is it dangerous to
0:59.8	take too much vitamin D? It can be, especially with hypercalcemia, too much calcium in your
1:06.0	blood, which can lead to kidney stones. On the flip side, what are the dangers of not having enough
1:12.5	vitamin D3? It makes you more susceptible to autoimmune diseases. Autoimmune diseases are the number
1:20.4	one health problem on planet Earth right now. Talking about MS, graves, lupus, rheumatoid
1:26.9	arthritis, type 1 diabetes,
1:29.2	vitiligo, which is a skin problem, and Hashimoto's is at the top of the list.
1:33.7	That is a hypothyroid condition.
1:36.0	Your own body is attacking itself.
1:39.0	That part of the immune system is heavily influenced by the amount of vitamin D that you have
