The normal range for vitamin D levels in the blood is typically considered to be between 20-50 ng/mL (50-125 nmol/L). However, some experts suggest that levels above 30 ng/mL (75 nmol/L) are optimal for bone health and overall health.
It’s important to note that the optimal vitamin D level may vary depending on individual factors such as age, overall health, and risk factors for deficiency. Your healthcare provider can help determine your optimal vitamin D level and recommend appropriate interventions if your levels are low.
