What does take two by weekly mean?

My doctor prescribed me vitamin d for my low vitamin d blood count from my complete blood work.

I took one vitamin today when I first got it, but I don't understand what "take by weekly means" 

Does it mean take every third day?

weekly or bi-weekly?

Weekly means every 7 days
Bi-weekly means every 3 or 4 days

Typically the daily dose is from 1,000 to 5,000 Units. 
The weekly or even bi-weekly is 50,000 Units.

Bi weekly is ambiguous since it could mean twice a week or every 2 weeks.
Vitamin D is not harmful, you can take it every 3 or 4 days.  Or you could ask your doctor what he meant.

I think that is bi-weekly, which is ambiguous, as it can mean every 2 weeks or twice a week. Ask the doctor or pharmacist to clarify.

Bi-weekly.  That can mean once every two weeks, or it can mean twice a week.
