The high dose I need!
I live in Tasmania where the winter daylight is very short, which means I require a large amount of vitamin D to stay healthy. These soft gels are small in size and easy to swallow. It is impossible to find 10,000 IU dose capsules in Australia, so it is amazing to be able to get them through iHerb!

Good product with good results
I ordered this supplement because of blood tests I had and the doctor's advice. After checking the company and all the ingredients, it was found that this is the product that suits me best. I have been using it for over a month and feel better and my blood tests are also good. For the price, the value is excellent and I will definitely order again.

So good for the entire body
I like this one because of good quality and dosage. I take two capsules per day: 20 000 IU, because as we age we need much more of vitamin D3 than usually suggested (by Dr Berg).
