VitaminDwiki – High-Dose contains:

High Dose = the on-going use of >5,000 IU (daily average)
Dosing frequency: 1 per day to 1 per 17 days is best, however some studies use monthly dosing
High Dose has been used millions of times - safely and effectively
High Dose for more than 6 months should include the adjustment of co-factors
>100,000 daily can be toxic in 3 weeks if cofactors are not adjusted
Can be via injections
High dose is not the same as a Loading Dose (bolus)
- A Loading Dose is a high-dose typically completed in less than 30 days
