Vitamin D level of 9.8 ng/mL indicates significant deficiency. Since you have already completed 60,000 IU once weekly for 4 weeks, I would not recommend starting 5,000 IU daily on your own immediately afterward.
Although 5,000 IU/day may sometimes be prescribed for specific cases, it is higher than the usual tolerable upper intake level for routine self-supplementation, so it should preferably be taken under medical supervision.
Regarding Vitamin K2, it is not automatically required with Vitamin D for everyone. Please discuss whether you need it with your doctor, particularly if you take any blood-thinning medication.
Next Steps
The appropriate next step is to repeat your
Vitamin D test after completing the prescribed loading course and then decide on the maintenance dose based on your updated level, diet, sun exposure and overall health.
Health Tips
Please don't adjust the dose yourself—repeat the level and review it with your treating doctor before continuing with a higher maintenance dose.
