If there's only one supplement you're taking for your health and your diet is decent, it should probably be Vitamin D. I highly recommend taking Vitamin D instead of a multivitamin most of the time. The standard supplement is Vitamin D3, otherwise known as cholecalciferol. Vitamin D3 tends to be better absorbed than other forms of Vitamin D. Vitamin D is an essential vitamin known as the sunlight vitamin, due to synthesis occurring in the skin from the sun's radiation. It has a multitude of benefits to the body including supporting bone structure, mood state, and is generally seen as healthy and anticancer. The RDA for vitamin D is currently set at 400-800IU/day, but this is likely too low for adults. The safe upper limit in the United States is currently defined as 2,000IU/day, and in Canada it's 4,000IU/day. However, research suggests that the true safe upper limit is 10,000IU/day. Supplemental vitamin D is implicated in wide-ranging benefits, such as increasing cognition, immune health, bone health, and well-being; reducing the risks of cancer, heart disease, diabetes, and multiple sclerosis; and increasing testosterone levels in deficient populations. This product by 21st Century Health Care offers a cost-effective supplement for the benefits mentioned above. Taking everything into account, I highly recommend this high quality product. I hope you'll find my review helpful to you.

This product can be better if they use vegetable cellulose or vegetable lubricant instead of stereate in the other ingredients. I also noticed calcium carbonate as one of the ingredients aside from Vitamin D3 from cholecalciferol. Calcium carbonate came from limestones. I prefer organic, natural, Non GMO and vegan products.

I give the product only two stars because I think that there are many other better vitamin D products available at iHerb. Usually vitamin D products do not need any magnesiumsterate and they are in oil capsules for better absorption. 1,000 IU = 25 µg vitamin D3, the best form of vitamin D. You should meaure your vitamin D level sometimes to see that you are getting enough this very important sun vitamin. I have measured my blood serum 25-Hydroxyvitamin D, 25(OH)D three times and last time 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 that is 2,000- 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. I hope you find this review helpful.

I need vitamin D because I live in the PacNW and I get S.A.D.s and while I do get a minimal mood improvement it is not lasting. I will continue to take the rest of these and see if I should came back and change my review in about 2 months.

I only bought this because it was on sale for like 15 cents.. So I was just like "why not?"... Anyways I think there are much better brands of vitamin D3 out there. This is so cheap that it probably isn't that great of a brand.

I did not look at the other ingredients when I bought this, but I had a dry feeling in my mouth after taking this for a month. I stopped taking it and dry feeling was gone! From now, I will always pay attention to the other ingredients in supplements. Lesson learned.
