Answer :
5 tablets must be taken by the patient each day.
In a randomized clinical experiment with nursing home residents, the effects of equal oral vitamin D3 doses of 600 IU/day, 4200 IU/week, and 18,000 IU/month on vitamin D status were compared. The most efficient dosage was a daily dose, followed by a weekly dose and a monthly dose. It is believed that vitamin D status is affected equally by equivalent daily, weekly, or monthly doses of vitamin D3. A randomized clinical experiment including nursing home residents looked at this.
we know that for 1 day we need to divide 1.25 by 0.250
so, the answer will be 5 pills per day.
