How Much Vitamin D3 Should I Take? Is 10,000 IUs of Vitamin D3 Toxic? – Dr.Berg

So today I want to answer a specific question about the units of certain nutrients. When youget into the fat soluble vitamins, they don’t usually use milligrams. They use somethingcalled international units. Now there’s a comment on one of my YouTube videos of someone that wasconcerned about vitamin D and she didn’t want to take 10,000 international units of vitamin Dbecause it sounded so large of an amount and she wanted to know if that would create a vitamin D

toxicity. So I want to differentiate the different units that are used in certain nutrients. You haveinternational units, okay? And then you have milligram or microgram units. So internationalunits are really the potency or concentration of something. So it’s a little complex to convertinternational units to milligrams or micrograms simply because this is the concentration.And this isn’t necessarily the concentration, it’s the amounts. So you don’t need to really

be alarmed if you see large amounts of international units because let me show you something.One international unit of vitamin A is only 0.3 micrograms of retinol. Okay, that is so small.And 0.6 micrograms of beta carotene. Okay, so you can see it’s very, very small. Let’s just takevitamin D, for example. One international unit of vitamin D equals 0.025 micrograms, not evenmilligrams. Let’s just take, for example, 10,000 international units of vitamin D. What does that

really come out to in milligrams? It’s going to be 250 micrograms, not milligrams, or 0.25milligrams. That’s a quarter, one-fourth of just one tiny milligram. So you would need 40,000 IUsof vitamin D to equal one tiny milligram. I mean, 15 minutes in the sun will give you 20,000 IUsof vitamin D. And yes, I just want to bring this point up that even though you can get a lot of IUsof vitamin D from sun, your body will buffer it to prevent your body from ever becoming toxic

versus consuming certain foods or supplements. You could overdo it with vitamin D,but I always recommend taking vitamin D with vitamin K2. Vitamin K2 works with D3 to helpmobilize calcium and keeping it from going in the wrong place. But you’d have to consume a lot ofvitamin D3 to create hypercalcemia, by the way. It’s not very common and you would have to consumeit over a long period of time. But 10,000 IUs is really not that significant, especially if you’re

taking K2. Now, what are some of the symptoms of hypercalcemia? That’s too much calcium in theblood. High blood pressure, dehydration, decreased appetite, irritability, fatigue, and weakness.and by chance that you ever had too much calcium in the blood or vitamin D toxicity, it is sosimple to fix it and reverse it because all you do is you stop taking vitamin D for a whileand everything reverts to where it was. So I just wanted to bring this point up because I’ve had

several people ask me about this amount and is it that toxic? The answer is no, it’s not.Thanks for watching. So to prevent me from running out of content, I have a new survey. I want tofind out what you are interested in. So please fill it out. The link’s down below.
