B12, Omega-3s, and Calcium for Vegans

The most important thing with B12 is to get cyanocobalamin, in the right dose, in a chewable or sublingual form. A recommendation is 2,000 micrograms once a week for those under 65 and 1,000 micrograms once a day for those over 65. For Omega-3s, Algae-based DHA is recommended at 250 milligrams. Calcium supplementation is not helpful or safe, so it's best to get calcium from natural sources like low oxalate, dark green leafy vegetables, tofu, and sesame seeds.
