All right, this is pretty cool.

I'm going to show you how to make your own vitamin D supplements using mushrooms.

Now mushrooms are normally grown in the dark, and the only light they see is some fluorescent

light when they're either being picked or processed, and mushrooms have very insignificant amounts

of vitamin D. Unless you expose that mushroom to ultraviolet B light, and there's some

very cool research on exposing these mushrooms to light and boosting the vitamin D levels

to levels far greater than the RDAs.

You can boast the vitamin D in mushrooms to levels of 5,000 international units to 46,000

international units and beyond.

And so in this video, I'm going to show you exactly how to do it.

You can use oyster mushrooms, shiitake, mataki, or button mushrooms, and there's other

mushrooms you can use as well.

And when they did the research and exposed mushrooms to light, they found that if you

exposed the gills, the little ridges underneath the cap, you get the maximum conversion to

vitamin D.

Now, because the button mushrooms don't have those little gills, we're going to cut them

or slice them lengthwise to expose more surface area to create a similar effect.

Now I will say that the type of vitamin D mushrooms have is vitamin D2.

And so it's a slightly different version of vitamin D and it's not as bioavailable

and it has a shorter half-life, but that's okay because you're going to be boosting the

levels of vitamin D at a really good range.

So the amount of absorption you're going to get is going to be pretty good.
