This is the best vitamin D on the market! My vit D levels increased after i started taking it. This vitamin helps improve immune system, and stay helthy. The tiny capsules are soooooo easy to swallow. I take it as suggested, with food. No problem with stomach, digestion or any aftertastes. I am very happy with taking this vitamin D.
The softgels are really small and easy to swallow. Each softgel is 2000 IU which is within the recommended dosage daily. I've read that too much Vit D3 could be harmful so it is good that this isn't over the dosage. I've taken this daily for couple of weeks but to be honest, I've not noticed any difference (hence the 4 star to be cautiously optimistic).
I did research before deciding which brand to buy. It's not the cheapest one, but it is a very reputable brand and the product is made in the US. You want to make sure whatever you put into your body is safe and effective. Have been using it for a while now, no complaints!
