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.

For what it is worth, I used to take Nature's Way vitamin D, 5,000 iu and my blood test after 6 months or so was 54. I switched to Dr. Best because I ordered their Vitamin C, however, this last blood test my vitamin D level dropped to 31. It was the same potency of 5,000 iu. So I am disappointed in these results and just re ordered the Nature's Way again.

Dr Best products normally are on hi dosage! And this Vitamin D is 5000 IU. It came to my knowledge that hi dosage is usually more than 2000 IU is harmful to the health & this one is 5,000 IU. MADNESS!! Do not take this thing for long-term basis meaning above a year!

I'd have never bought my vitamin on this site, I bought some things on 7th of march and until today I didn't receive it. its take a long time to get, if I know this I would buy in my city. I know on this site is very cheap and there are lots of things that is difficult to found it but in another hand, I can take it in time I want.
