We asked the dietitians at SportsRDpro to answer a few questions about Vitamin D.
Q: How much vitamin D do I need?
A: The Institute of Medicine (IOM) recommends serum Vitamin D levels to be 75 nmol/L.
Q: How do I know if I have enough Vitamin D?
A: The best way is to get your blood levels checked by a doctor, especially before starting supplementation!
Q: Who is at increased risk of Vitamin D deficiency?
A: Breast fed infants, older adults, people with limited sun exposure, people with dark skin, people with inflammatory bowel disease and other conditions causing fat malabsorption, people who are obese or who have undergone gastric bypass surgery
Q: How can I increase my Vitamin D?
A:The primary source of Vitamin D is sunlight! Approximately 5–30 minutes of sun exposure between 10 AM and 3 PM at least twice a week to the face, arms, legs, or back without sunscreen usually lead to sufficient vitamin D synthesis.
Q: Do athletes need more Vitamin D?
A: There is Possible evidence that Vitamin D may improve athletic performance and recovery, but more research needs to be done. Additionally, Vitamin D may play an indirect role is resistance to injury (stress fractures). More studies need to be done in the athletic population to determine whether vitamin D serum levels of > 100nmol/L provide additional benefit.
