In 2007 the NIH raised their recommended upper daily limit of Vitamin D to 10,000 IU. The goal is to reach 25(OH)D3 blood levels of between 75 and 125. As a guideline, daily dosing of 5,000 IU will increase 25(OH)D3 by 50 points over 3-4 months. 10,000 IU and 25,000 IU dosing will proportionally increase these levels or decrease the time necessary to reach desired blood levels.

Great supplement!
We all need some extra Vitamin D for those gloomy days. This a great source.
My Dr. recommended I take D3 and this is a very good quality and I am on my 2nd bottle.
It's a great product but you need to take it in the morning and not on empty stomach, it causes strong headaches due to high dose when taken later in the day or if you didn't eat/drink enough. Still, it's very hard to find such dosage, just be careful how you implement this into daily routine.
