Is Vitamin D Level Of 13 A Cause For Concern?

I have a vitamin d level of 13. I was prescribed a strong dose for the next 8 weeks. Then I will pick up an over the counter vitamin d supplement. Is there anything I need to look for in a good d supplement? This is something I haven t done much research on.

Hello dear
Understand your concern.

Please note the Vitamin D status definition:

Severe deficiency      Deficiency      Sufficiency      >20 ng/mL
Risk of toxicity      >50 ng/mL

So your are in deficiency state.
You should take 50,000 IU/week for 8 week.
You can also take stoss therapy: 3-6 lakh units over 1-5 days
keep the serum levels of 25(OH)D >30 ng/dL which is considered to be the optimal level.

Exposure to sunlight for 2 hour / week with open hand , forearm and face, feet between 10 am to 12 noon

However, to maintain vitamin D level in the sufficiency range the duration of UVR exposure particularly in relation to time of the day, season or skin pigmentation, remains to be determined.
Excessive exposure to sunlight dose not lead to vitamin D toxicity.

Dietary supplement:
Oily fish such as salmon, mackerel and sardines,
cod liver oil, liver and organ meats and Fortified milk and its product

Hope this may help you.
Best regards
Dr. Sagar
