I had been taking another brand of Vitamin D, but after changing to Natural Factors, my levels improved into the normal range for the first time in several years.

My husbands doctor told him to take these tab 2x a day, this was the best price, and I think they are helping my husband who does not get out in the sun at all.

Everyone needs Vitamin D3 and 2000 IU is the best dose. Lived in Alaska for many years and the D helped get through the low light times.

There are so many health benefits for taking D3 that you can check in vitamin books and do research. But since my ND doctor recommends this brand as one of the better brands using the higher quality ingredients and standards, I usually stick with this brand.

For some reason I do not tolerate the D3 in oil.. This is slowly bringing up my D3 level.

The best supplement i have taken in ages! It's a miracle. I am vitamin D deficient and I am doing much much better with this!!!

More and more evidence suggests that we simply do not get enough D3 in our diets or through exposure to sunlight. Being winter time, I have stocked up on this great product and so far have not been plagued by illness. You can't beat the quality or the price of this gem.
