How Much Sun Is Needed to Keep Healthy Vitamin D Levels?

Read Transcript

It depends, it depends on many variables probably a dozen or more different variables I can think of. Depends on the time of the year, if you're in New York in December or January, you could stand outside without any clothes on in full sunlight all day long and not get any vitamin D.

Conversely, if you're an African American with deeply pigmented skin, you can stand up there in the middle of the summer and you might still need several hours. So the skin color, the time of the year, the latitude you're, the cloudiness, the altitude plays a role, so these are all variables.

Ultimately, you want to get enough, enough vitamin D and not too much. You never want to get burnt, never want to get burnt because the moment you get burnt, you're not going to make anymore vitamin D and you're only causing increasing your risk for skin cancers and causing photo aging.

So those are the things you want to avoid. So, typically how do you know if you're Caucasian, typically the lightest bit of pink on your skin will be enough, but ultimately the only way to know for sure is to do a blood test. And I like, you can get one from your physician but there's a non profit organisation called grassrootshealth.net, they can send one to your home, it's really easy and convenient to do, it's only $40 and you can find out pretty easily that way.

But ultimately you want to get your blood level tested and I would 60-80 mg/ml but at least 40. Anything below 40 is definitely too low.
