Just because you get plenty of sunlight where you live it doesn’t mean you get enough exposure to produce vitamin D.

You need to expose large areas of your body like legs, arms, and torso for several minutes to an hour. If those areas are covered, sunlight won’t do much.

The Sigma Nutrition podcast has an excellent episode on that: https://sigmanutrition.com/episode438/

Nah, for me, that wasn't sufficient. I get at least 10 hours a week of full sun on my whole arms and legs and sometimes my torso if I decide to bike shirtless; more sun than most people, and still, I was vitamin D deficient.

Did you wear sunscreen? I'm pretty sure it blocks vitamin d creation, which really makes me wonder how any of my GFs Ive had ever got any since they wear it religiously in hopes of keeping youthful skin.
