Hello,
A
Vitamin D level of 13 ng/mL is indeed low (normal >30 ng/mL). Yes, you will need supplementation. Here's a general treatment plan:
Treatment:
Vitamin D3 (Cholecalciferol) 60,000 IU once weekly for 8 weeks.
Follow this with 60,000 IU once every 2 weeks or monthly for maintenance, based on your follow-up level.
Take the tablet after a meal (preferably lunch) for better absorption.
Lifestyle:
Get 15–20 minutes of direct sunlight on bare skin (arms/legs) between 10 AM – 12 PM without sunscreen, at least 4–5 days a week.
Include Vitamin D-rich foods: egg yolks, fortified milk, mushrooms, and fish (like salmon or sardines).
Next Steps
Recheck Vitamin D levels after 12 weeks of supplementation.
Consider checking
calcium and PTH levels if symptoms persist.
Maintain physical activity for better bone health.
Helpful Tips
Avoid overuse of supplements—excess Vitamin D can cause toxicity.
Always take Vitamin D with food containing fat for best absorption.
Drink plenty of fluids and maintain a balanced diet.
