Converting sunlight to Vit D, Research in neurobiology, Kinhin, other

Yeah, it's fascinating how that works! When your skin is exposed to sunlight, specifically UVB rays, it triggers a chemical reaction in your skin. The UVB rays convert a cholesterol-like molecule called 7-dehydrocholesterol into vitamin D3. Then, your liver and kidneys process it further to make the active form your body can use.
