//All about Vitamin D2
Plants produce this form of Vitamin D when they are exposed to UV light (in much the same way as our bodies naturally produce Vitamin D). The most common example is wild mushrooms or mushrooms produced under UV light. Dairy-free milk (including soya, coconut, and almond milk) are often boosted with D2.
All about Vitamin D3
Vitamin D3 is the biologically active form of the vitamin, found in our bodies and in animals. When sunlight hits exposed skin, a reactive process converts cholesterol into Vitamin D3.
Although you need both forms, Vitamin D3 is more important for your health and wellbeing. Our bodies absorb and use Vitamin D3 better, and it is more effective at treating diseases.
Studies have shown that it’s Vitamin D3, not D2, that maintains levels of Vitamin D in our body even over winter months. It’s important to note that dietary sources of Vitamin D3 can only be found in animal products. So if you’re vegan, you need to pay extra attention to supplementing your diet with Vitamin D3.//
