Hello there.
I can understand your concern.
Uprise D3 60k once a week is good. You can take cod
liver oil along with that no problems but not three times a day. Only once a day after food is enough.
Also you need to drink one glass of milk every night before bed.
Expose your body to sun for atleast 20 minutes a day so that your body can synthesise
Vitamin D3 naturally.
Tablet will full fill the deficiency and exposing to sun will maintain a good level. And natural vitamin D3 is better.
Best regards.
