What role does MY FOODBOOK play in blood sugar?

The VDR gene encodes the vitamin D receptor, which helps your body use vitamin D. Variants in this gene are common, but their effect on vitamin D status is not straightforward. A DNA test alone cannot reliably tell you if you need more vitamin D. The best indicator is your serum 25-hydroxyvitamin D level. Have it measured before supplementing. Evidence linking VDR variants to clinical outcomes is weak and mostly mechanistic. Consumer DNA tests often overstate the impact. Focus on a balanced diet and consult a doctor for personalized advice. Do not self-supplement based on genetics alone.
