How do you know for sure your body stopped producing Vitamin D?
Not who you are asking, but most folks find out with blood tests. It is also pretty common for folks to produce less as they age, and it isn't a small difference.
Are you going out in the morning? That's when your get vitamin D, almost nothing in the afternoon.
This just isn't true. How much you get is going to depend on the angle and strength of the sunlight, the amount you get, the amount of skin exposed, and the color of your skin. (dark skin produces less than light skin, and makes it difficult to produce enough the further north/south you are).
- drivers99 3y agoThe angle of the sun is vital, which is affected by time of day, time of year, and your latitude. This is a chart showing time of day and year on the UV index, for a given latitude (NYC so about 41°N) https://www.grassrootshealth.net/wp-content/uploads/2019/05/NYC-UV-Chart.pdf https://www.grassrootshealth.net/wp-content/uploads/2019/05/...

- Namari 3y agoYes it looks like what I read in the past was wrong and you are right, it's about the angle of how the sunlight passes the atmosphere. Also about the cholesterol oil your skin produce and what you said.
