Vitamin D is beneficial. It is associated with the things listed in this video. Some of those effects are major, like storing calcium in bones, and triggering your sleep-wake cycle. Others are minor like the effect on weight loss. Other factors play roles more than an order of magnitude more important.
Like any vitamin, there is a range in your body that it needs to do its thing. There's a level below which you're deficient and get symptoms of that, like decreased immunity. There's a level above which you get toxic effects, so you don't want to exceed it. Vitamin D has a large range to work with.
20 minutes in the sun daily, at peak hours (10A-2P), will provide enough UV exposure to keep you at normal Vit D levels if you're otherwise healthy. Some people need to supplement, especially in the winter, if they can't get outside during those hours. 400-600 IU daily is enough to maintain normal.
If you're low, you'll only know it with a blood test, which your physician will have to order. Then you replete with a supplement, following their dosing schedule. Lots of complications here, so I won't presume to start listing. Take what they tell you, if they tell you do.
You CAN overdose on Vitamin D, so I don't like people telling people to take megadoses (10,000 IU/week or more) unless they've got a doc monitoring their blood work. It's risky. Some people think they're "being healthy" taking many times more than they actually need for far longer than they should because they don't understand the physiology. It's ill-advised and potentially dangerous. With water-soluble vitamins, it's less of an issue. You just pee out the excess, but Vit D is fat-soluble and gets stored in the body's reserves. Toxicity risk can accumulate.
Like everything we consume, food, drink, or medicine, the dose makes the poison. Too much of anything can be harmful. Docs try to balance their recommendations, and what this genius in the video is complaining about is docs prioritizing advice to avoid melanoma (skin cancer) risk or similarly good reasons. He's asserting the docs are all evil and just trying to make ya sick. It's horse manure, just as much as the "health experts" telling you to take megadose Vit D just for funsies (how many of these are the ones selling you the supplements?)
