Blood test revealed Vitamin D3 level is 25, and my understanding is the acceptable range is (30-100 ng/ml; and my Doctor instructed me to take two (2) Vitamin D (ERGO) 50,000 IU CA per week, for the next four (4) weeks. First, is ERGO a Vitamin. D3 supplement or Vitamin D2? Second, is this too much Vitamin D supplement to take, even for this short period? Finally, should I expect my levels to increase and stabilize going forward if I take 2,000 IU of Vitamin D3 going forward. Thank you, Pat M
Your It D levels are in the insufficiency range and not really in the severe deficiency range. Anyway, the dose advised by your doctor is fine. Some doctors advise 60000 IU once a week for 12 weeks. The dose prescribed to you should normalize your It D levels. You can repeat your levels after 3 months to check on that. Post normalization of the levels, it is advisable that you expose yourself to early morning sunlight before 9am, like take a simple walk for half an hour. Alternatively you can take It D 1000 IU daily.
