We use Vitamin D3, also known as cholecalciferol. Vitamin D3 is the same form that occurs when sunlight hits your skin for 10-15 minutes. It's not derived from plant or fungal sources. Rather it's derived from animal sources when 7-dehydrocholesterol reacts with UVB ultra violet light. It is believed to be more effective at increasing the levels of Vitamin D in the blood and is the form most utilized in clinical trials. It's also more stable when exposed to temperature, humidity and other environmental conditions. Quality makes the difference.
