Vitamin D deficiency is quite common across the United states, affecting roughly 50% of our population. Although the body can synthesize this nutrient from sun exposure, it is challenging to get enough sunlight in winter months, especially for people living in northern states like Indiana. This can lead to an increased risk of vitamin D deficiency for these individuals.

Vitamin D’s main function is to make sure that the body has enough calcium and phosphorus. It is also required for joint and muscle health, mood regulation, immunity, and cell growth. Signs and symptoms of Vitamin D deficiency include drowsiness, depression, cuts that do not heal, joint or muscle pain, hair loss, bone loss, and decreased immunity.

Certain populations are at higher risk for Vitamin D deficiency. These include vegetarians and vegans, overweight or obese individuals, those who live far from the equator, and those with darker skin tones.

Seniors are also at a higher risk for vitamin D deficiency because the body’s ability to make this nutrient from sunlight decreases with age. With 7.9% of seniors in Indiana facing food insecurity, it is especially important that these clients can access foods that are rich in vitamin D, specifically in the winter months.
