Who is at risk of calcium and vitamin D deficiency?
- Female athletes in sports that focus on lean physique.
- Kids who choose to drink soda, juice and sports beverages instead of milk.
- Kids who are inactive or don’t spend time outside for sun exposure.
- Kids who are lactose intolerant or allergic to milk.
Why should we care about calcium and vitamin D for our athletes?
- Vitamin D promotes absorption of calcium, and we depend on these nutrients for strong bones (adolescence is when we build our bone mass).
- Strong bones help prevent bone injuries.
- Lack of calcium in our diet forces the body to take calcium from bones to keep blood levels normal, which weakens bones.
- Calcium is a key nutrient for muscle contraction, nerve transmission and hormone secretion (all of which are crucial functions for athletes).
What can you do to keep your athlete’s calcium and vitamin D levels healthy?
- Ask for a vitamin D level on your child the next time they get their blood drawn.
- Encourage calcium and vitamin D rich food and fluids 3-4 times per day.
- Ask your provider if they think your child might be a candidate for a calcium and/or vitamin d supplement.
