Dr. Wang Lei
Vitamin D2 can be obtained from plant-based foods such as nuts, peanuts, and legumes; vitamin D3 is synthesized by animals themselves and can also be acquired from animal sources such as liver and skin. These vitamins are primarily used for the prevention and treatment of deficiencies in vitamins A and D, including conditions such as osteomalacia, rickets, xerophthalmia and night blindness caused by vitamin A deficiency, and age-related or postmenopausal osteoporosis.
