Is 25(OH) Vitamin D the same as Vitamin D3? My recent report shows 25(OH) Vitamin D is 55.90. Eight months ago, my Vitamin D3 level was 13, and I took Vitamin D3 60,000 IU once a week for 3 months. I started taking it again for the past 1 month. Should I continue taking Vitamin D3 60,000 IU or stop now? Also, my current Vitamin B12 level is 494. Should I continue the B12 tablets or stop them?

25(OH) Vitamin D is used to assess vitamin D status. Your current level (55.9) is sufficient, you may stop weekly D3 and continue monthly maintenance. B12 is 494 (normal), stop if no deficiency symptoms.

I am 30 years old and have been experiencing knee pain for the past month. My X ray shows no abnormalities, and doctors suggest it might be due to calcium deficiency. I am taking calcium supplements and have been undergoing physiotherapy sessions for the last 15 days, but the pain persists. My blood test shows an ESR count of 44. Could you please advise if this is something serious and what further steps I should take?
