Vote On These GrassrootsHealth Vitamin D Resources
(#1) Newest e-Tool: The Vitamin D Deficiency Risk Assessment Quiz
To help educate everyone about their unique, individual risk factors for vitamin D deficiency and to highlight when testing may be of extra importance, we have created The Vitamin D Deficiency Risk Assessment Quiz (Beta), a short set of questions about an individual’s supplemental vitamin D intake, UVB exposure, and low exposure indicators to assess risk level. Scoring is intended to determine if an individual has a low, moderate, or high risk of having a vitamin D level below 40 ng/ml (100 nmol/L). This tool can also help motivate individuals to take their supplements or take other steps to reach and maintain healthy vitamin D levels!
To help further validation of this e-Tool, individuals who complete the quiz will receive a coupon for $5 off their next kit order, and will be encouraged to complete their questionnaire and vitamin D test within a month of completing the quiz. This coupon can be combined with any other offer.
(#2) Most Popular e-Tool: The Vitamin D*calculator
Use the Vitamin D*calculator to calculate the estimated Vitamin D intake needed to reach your target vitamin D serum level (40-60 ng/ml recommended by our scientist panel). The calculator is best used when a current/starting vitamin D level is known.
