Dr. Friedman and other doctors frequently prescribe a high dose (50,000 iu) of vitamin D weekly for 8 weeks, but this is D2 and in many people the levels drop down to normal after nor taking it for a few months. This needs to be given by a prescription. Vitamins and preparations like Oscal D contain D3, however the amount in these preparations are small.
For example, each multivitamin contains 400 international units of vitamin D3 so a total of 800 international units of vitamin D will probably prevent Vitamin D deficiency and may correct very mild cases of low vitamin D levels, but is not enough to correct most cases of vitamin D deficiency. For more severe levels, the patient can take 50,000 international units of vitamin D orally once or twice a week.
Dr. Friedman finally found a product that has high doses of D3 that could be used to rapidly restore vitamin D levels in patients that are deficient and keep the levels up. This product 50,000 iu d3 is sold in bottles of 12 by bio-tech-pharm.com and is catalogue D-3-50. The website is https://secure.bio-techpharm

For a 25-OH vit D levels between 20 and 25, Dr. Friedman recommends taking one pill a week for 8 weeks, then checking a 25-OH vitamin D. If levels are in the normal range, then you can take one pill a month for the next 6-12 months for maintenance. After 6 months, you should be adequately treated. For patients with 25-OH vit D level between 25 and 30, one pill a week for 6 weeks is recommended. For patients with 25-OH vit D level less than 20, it is recommended to see your Endocrinologist to determine proper treatment. If levels are in the normal range, then you can take one pill a month for the next 6-12 months for maintenance.
Please take the pills weekly and not daily.
The main side effect of vitamin D therapy is overtreatment leading to hypercalcemia.
