What is the average level of vitamin D in the human body?
There is no definitive answer to this question, as vitamin D levels vary from person to person. However, generally speaking, a healthy vitamin D level in the body is around 20-32 ng/mL. Anything below 20 ng/mL is considered deficient, while anything above 32 ng/mL is considered optimal. Vitamin D levels can be measured through a simple blood test.
Vitamin D dosage
Most people need between 600 and 800 IU (international units) of vitamin D daily to maintain healthy levels. However, some people may need more than this, depending on their age, weight, bone density, and other factors.
If you think you might be deficient in vitamin D, talk to your doctor about getting a blood test to check your levels. They can also recommend the best way to increase your vitamin D intake, whether through diet, supplements, or exposure to sunlight.
