These capsules are small and very easy to swallow. 5,000 IU = 125 µg vitamin D3, the best form of vitamin D, has been the right dosage for me all year round, although I am quite small in size. I have measured my blood serum 25-Hydroxyvitamin D, 25(OH)D three times and now in March 2015 my test result was 141 nmol/L = 56.4 ng/ml. My test result was now at optimum level which is 125 - 150 nmol/L = 50 - 60 ng/ml when you are taking enough Vitamin D. I will continue with the same dosage 5,000 IU daily to keep my vitamin D level right. There is no need to worry about overdosing because the tendency for serum 25(OH)D to rise when the starting level already is higher is very gradual.

I have taken this D3 because it contained olive oil not soy oil. In fact the bottle I have indicates olive oil and "contains nothing other than listed ingredients". The information listed now indicates "soy oil" on iherb, but the Dr. B website indicates olive oil. I still think this is a good product. I will write iherb to investigate the product.

I do find it weird though, that I take 2 of these a day, plus whatever little is in my multi, and my bloodwork always shows that my D is in the normal range, but low-normal.

A good product at a good price. The dosage is a little higher than most people would want, but otherwise, a good choice.

helps with my fatigue and lethargy but subtle difference only. on days that i didn't take it, i felt so blue and depressed. so this helps me be more alert.
