Crucial for normal bone development, vitamin D helps the body absorb Ca. The vitamin is naturally synthesized in the skin in the presence of sunlight. But inhabitants of northern countries, where sunlight is reduced during long periods of the year, need to eat food rich in vitamin D or take supplements to avoid problems such as rickets & osteoporosis
Although fish, milk, & liver are rich in vitamin D, eggs could be a particularly good source. That's because, in addition to having the D3 form of vitamin, eggs also contain significant levels of the more active 25-hydroxy-vitamin D3
