This incredibly important vitamin in our bodies is a pro-hormone of which the final production in the skin is dependent on sunlight exposure. You can make a lot of your vitamin D3 from sunlight, but there are biological, environmental, and practical limits that prevent most people from getting all they need this way. Here’s why:
After 10 - 20 minutes of strong sun exposure, further UVB turns previtamin D into inactive photoproducts, not more vitamin D. This is a natural protection mechanism against toxicity.
Melanin acts as a natural sunscreen. Darker skin (higher melanin) requires much more UVB to make the same amount of vitamin D as lighter skin.
SPF 30 can reduce vitamin D synthesis by 95%. But do not ditch the sunscreen! Your risk for cancer will skyrocket.
You could attempt to get all your vitamin D from sun, but the outcome would be:
⚠️Skin cancer risk
⚠️Photoageing (wrinkles, skin damage)
⚠️DNA mutations
Vitamin D from sun is highly variable. Supplements give consistent, measurable amounts. Vitamin D3 is an active ingredient in Largavita's NADplus+ Complex. You can find details of stockists on our website.
