I’d like to supplement but every time I take one I get muscle cramps. I suppose it’s just pulling all the magnesium out of my body or something? I tried magnesium supplements with it but it didn’t help. Maybe 5000IU is just too much?

Yes, this is the reason people further from the tropics tend to have lighter skin and are more likely to have genetics allowing for lactose tolerance throughout life. They're natural adaptations by the body, in response to being in an environment which sunlight (and therefore vitamin D) is more scarce.
So you're saying darker skin prevents the body from producing vitamin D? (Not saying it doesn't, I just didn't know.) Also, what does lactose (in-)tolerance have to do with… anything? To my knowledge, the fact that lactose tolerance is that common among Europeans is largely a result of thousands of years of domesticating dairy animals.

Some might not like this answer but the best course of action is still some sun exposure. As for the actual answer, someone correct me if I'm wrong but there there are multiple 'variants' of vit. D and the vast majority of "vit D" supplements most likely don't include the complete formula (which is arguably the best way in order to also assimilate it "fully"). The daily recommended dose is fine unless you're deficien…
There's an app called Dminder that notifies you when the sun is in the optimal position (highest point in the sky) to generate Vitamin D based on your location.
Hey people who follow the science: As an “indoor human”, how much should I be taking? (TIA!)
