Vitamin D3 (cholecalciferol) is a nutrient that is critical to many bodily functions. Vitamin D3 is beneficial for supporting bone health, immune wellness, cardiovascular function, and cellular metabolism, among others. Mounting research is highlighting the ever-increasing benefits of optimal vitamin D3 status. Vitamin D3 is known to interact with over 200 different genes and thus plays a crucial regulatory role as a metabolic activator for a multitude of metabolic processes.

iHerb Customer Reviews
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. If you found this review helpful, kindly indicate that by clicking on the Yes Button, thank you.
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.

it not only arrived so fast right at my door but also are small pills that are not threatening. got 180 of them in one bottle so its nicely priced too. for people who dont really go out often in the wintertime needs more vD than others. i got this product for that reason. Also vD is supposed to be working for cancel prevention.
