One of the best sources of vitamin D occurs naturally from sunlight. However, those of us living in Winnipeg are in short supply of this natural resource in the winter months. Some symptoms of vitamin D deficiency include depression, reduced wound healing capacity, fatigue, or becoming sick often. During the winter months, consider asking your physician about taking a vitamin D supplement, or eating foods that are high in vitamin D, such as fish (tuna, mackerel, salmon, and cod liver oil), egg yolks, beef liver, cheese, and mushrooms. When summer arrives again, go outside for some fun in the sun!
