Vitamin D deficiency results in impaired bone mineralization, leading to diseases such as osteomalacia (bone softening) and osteoporosis. Vitamin D also plays an important role in maintaining organ systems. The Canadian Food Guide recommends a minimum of 200 IU daily for healthy individuals, with the upper daily tolerance around 2000 IU. The only significant natural dietary sources are oily fish and egg yolks, but it is not possible to intake enough through these foods alone. 15-20 minutes sun exposure, twice weekly will produce enough Vitamin D as it is synthesized through the skin, or a daily supplement can be taken.
Are you getting enough vitamin D through your diet and supplement program? Your doctor can test you to see if you’re deficient or not. Is vitamin D deficiency a concern to you? Do you take a vitamin D supplement already? If not, would you consider supplementing or not, and why do you feel that way?
