             The recommended dietary allowance (RDA) is referred to as the daily dietary intake level of a nutrient considered sufficient to meet the requirements of 97.5% of all healthy individuals. The RDA per day for children and adults, ages 9-40, is 600 IU with 4000 IU tolerable uptake level. Dietary sources of vitamin D include food and nutritional supplements. The total vitamin D intake of an individual therefore reflects the combined dietary contribution from both foods and supplements. Some naturally occurring food sources of vitamin D include egg yolk, fatty fish and fish liver oil. Some foods however are fortified with vitamin D such as milk and margarine (Ross et al., 2011).
             Effects of Vitamin D3 and Gene Expression .
             The proof behind the connection of vitamin D and breast cancer risk has been developing in the late years. To completely comprehend the relationship between the two, Compos et al. studied the differences between the transcriptional impacts of 1α, 25 di-hydroxyvitamin D3 on breast carcinoma fibroblasts and normal breast tissue fibroblasts. Compos et al. acquired breast tissue samples from 5 postmenopausal patients between the ages of 42 and 64 years old. These 5 patients were diagnosed with primary ductal invasive breast cancer, which is the most common type resulting in 80% of all breast cancer cases. Ductal invasive breast cancer refers to cancer that originated in the milk ducks and has spread to/invaded the surrounding breast tissues (American Cancer Society, 2014). Two types of fibroblasts associated with the human breasts were then obtained from previously acquired tissue samples.
