Vitamin D3

What the brand says

Vitamin D is essential for strong bones and is needed to absorb calcium in the intestines and prevent calcium excretion in the kidneys. It also helps maintain blood levels of phosphorus and supports the immune system. Your body naturally makes Vitamin D using sunlight. Vitamin D is also found in fortified milk, fish, fish oil, egg yolks and beef liver. Many people are deficient in Vitamin D due to limited sun exposure and sunscreen use, inadequate Vitamin D consumption, digestive disorders and aging.
