How Much Vitamin D Do I Need?
So I get this question a lot .
How much vitamin d should we be taking on a daily basis ?
Well , I think we should probably go to the experts .
What the experts say about vitamin D
The vitamin d council , stated that healthy adults , which I’m still trying to find some healthy adults , need about 2,000 IUs , that’s international units , k , per day if you’re getting little to no sun .
Other experts recommend 400 to 800 IUs per day .
Now , here’s the problem that I need your help with .
I just don’t understand this .
How much vitamin D do we need per day?
When we take vitamin d , it’s in these units right here , international units .
But when they measure the blood , it’s not in international units .
It’s in NGs per milliliter .
So if you’re deficient in your blood , how do we know how much vitamin d to take because the units and supplements are IUs .
So it’s kinda weird .
I it’s I don’t know why they do that .
But if we take a look at the optimum concentration in your blood of vitamin d , it should be between 40 to 60ng’s per milliliter .
So if you had 20ng’s per milliliter , that would be considered low .
Well , let’s convert 20 ng’s per milliliter to international units per milliliter .
It would be 0.8 .
Pretty small .
But the question is , how much blood do we have ?
Because this is per milliliter , not all of your blood .
So we have about 5 liters of blood in the average size person .
And that would give us , if we do the math , 4,000 international units .Vitamin D .
So people that are deficient that have only 20 ng’s per milliliter really have about 4,000 international units of vitamin d , which is actually greater than what is recommended .
There’s some conflicting information here . Isn’t there ?
So just keep tracking with me here because if we take the optimum concentration , which is 40 to 60 , okay , how much vitamin d is this in international units ?
Well , if you do the calculations , it’s 8,000 to 9000 IUs .
That’s what’s normal in your blood .
So how are we gonna get this if we’re only recommending this or that ?
That’s what I just don’t understand .
It doesn’t make sense to me .
And on top of that , I don’t think you’re gonna absorb a 100% of your supplements .
Estimates show that you really only absorb between 60 to 80% , that’s in a healthy person , of these vitamin d supplements when you take them .
If you’re taking d 3 not d .
And so if we’re only absorbing 60 to 80 percent and you took , let’s say , 10,000 IUs in one day , you’re really only absorbing 6000 to 8000 international units of vitamin d 3 which just barely make the the normal amount that you need in your blood .
So there’s a big problem here because these recommendations do not match what we really need to normalize our blood values .
And then on top of that , if you’re taking these amounts and you have a deficiency or you have other problems like inflammation or you don’t have a gallbladder or you have gut damage from past antibiotics or you’re older or you have insulin resistance or you are obese , there are so many barriers that are gonna prevent you from absorbing this vitamin d .
Anyway , what I would recommend for the average person is to take at least at least 10,000 IUs every single day .
And on top of that , get some sun if you can just to meet the , minimum requirements that your body needs .
And another point I wanna bring up is that vitamin d is the most important vitamin because it’s so important for your immune system to maintain a healthy mood , to keep inflammation out of your body , and not to mention your bone structure , your teeth .
So it’s no wonder why the great majority of the population is deficient in vitamin d .

key Points:
- The Vitamin D Council stated that healthy adults need 2000IU of vitamin D per day if they’re getting little or no sun. Other experts recommend getting 400-800IU per day.
- The problem is that vitamin D is measured in international units (IU) in supplements. But, when it’s measured in the blood, they use ng/mL. So, it makes it confusing to know how much vitamin D someone should take if they’re deficient.
- The optimum concentration of vitamin D in the blood is 40-60ng/mL. So, if you had 20ng/mL, that would be low. But when you convert 20ng/mL to international units, you get 0.8IU/mL. An average-sized person has about 5L of blood, which would give us 4,000IU of vitamin D.
- Something doesn’t add up. This means that people who are deficient in vitamin D with 20ng/mL have about 4,000IU of vitamin D, which is greater than what’s recommended.
- So, how much is the optimum concentration of vitamin D in the blood, which is 40-60ng/mL, in international units? The answer is 8,000-9,000IU. This is what’s actually normal in the blood.
- How are you supposed to get the vitamin D you need if you only take the recommended amount? On top of that, you’re probably not absorbing 100% of the vitamin D you take.
- I believe the correct amount of vitamin D the average person should take is at least 10,000IU per day. They should also get plenty of sun exposure if possible.
- I believe vitamin D is the most important vitamin—make sure you’re getting enough.
