Softgel is very easy to swallow, small in size. I like the fact that they have used extra virgin olive oil. 2,000 IU = 50 µg vitamin D3, the best form of vitamin D. You should meaure your vitamin D level sometimes to see that you are getting enough this very important sun vitamin. I have measured my blood serum 25-Hydroxyvitamin D, 25(OH)D three times and last time 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 that is 2,000- 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 hope you find this review helpful.

Vitamin D3 is pretty typical vitamin to purchase. I don't see that Doctor's Best is necessarily any better than anyone elses. The prices are comparable to buying it from a health food store locally (in which the proces are low to begin with). As long as the quality of the oil is good.
