How to IU calculation in batch size

Label claims 250IU of Vitamin D3. Please give the calculation of how many grams of Vitamin D3 will be added in the batch of 1.5 lakh.

There are some counter questions that you need to answer:

  1. Is this label claim for the formulation that is to be compounded?
  2. Vit D3 “250 IU” per what?
  3. What is the form of Vit D3 you are using as input? Is it pure crystals? (If yes, that would be 40,000 IU per mg)
    If it is a diluted version, see the label for its strength (potency).
    Rest is plain arithmetic.
    If you still need help, please write back. Good luck.
