This is another very important vitamin that everyone should be mindful of. Sunshine is a great natural form of Vitamin D, and even fair-skinned people should try to get a few minutes of sunshine a day on bare skin. There is no need to risk skin cancer—just a few minutes of mild sun on your arms or hands is a helpful way to obtain a natural source of Vitamin D. If you are very fair-skinned then you can do so when the sun is mild, such as in the mornings and late afternoons. Vitamin D deficiency is becoming a worldwide concern, therefore you may also choose to consume a dietary supplement, especially if you are someone who is suffering from low Vitamin D levels. The vegan source of dietary Vitamin D is D2 (ergocalciferol), usually synthetic or manufactured from yeast. It can be obtained in a tablet form, or found in supplemented foods such as some soy milks. Vitamin D3 is NOT vegan. If you are curious about your own Vitamin D level, you can schedule a 25(OH)D (25-hydroxyvitamin D) blood test.
