Alfalfa
Alfalfa is high in protein, calcium and other minerals, vitamins in the B group, vitamin C, vitamin D, vitamin E, and vitamin K. The sun-dried hay of alfalfa has been found to be a source of vitamin D, containing 48 ng/g (1920 IU/kg) vitamin D2 and 0.63 ng/g (25 IU/kg) vitamin D3. There is reference to vitamin D2 and vitamin D3 being found in the alfalfa shoot; this is awaiting verification. Mushrooms are not allowed in Jain vegetarianism, making alfalfa the only known source which Jains can use to make vitamin D2 supplements.
