We all know that Vitamin D is essential for bones, muscle health, and possibly even to the extent of skin and immune health. The standard daily maintenance dose of vitamin D is approximately 600 International Units (IU).1 In order to achieve that daily target, below are some examples of the equivalent daily amounts of common vitamin D rich foods that you have to eat:1
1) Salmon = 113g
2) Tuna = 331g
3) Eggs (Large) = 14eggs
4) Milk (Fortified with Vitamin D) = 5 cups of milk
The information above is just to highlight that most people do not consume that amount of Vitamin D in a day and thus, may have low Vitamin D levels. However, having said that, don't just go to your nearest pharmacy and pick up a vitamin D supplement because you think you are low. If you are ever unsure, there is no time like the present to visit your local doctor and get a simple blood test performed
