iHerb Customer Reviews
► A Cost-Effective Supplement For Many Great Health Benefits !
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. I am a strong advocate on scientific medical research and evidence-based information, and constantly want to differentiate between marketing hyperbole and real world effects.

It was cheap

Posted by DrJah24 on Jan 11, 2017

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.

愛貓在家曬不到太陽(窗簾都不開),所以要服用D3,加上鈣,改善骨質疏鬆,值得一提的是我家的貓(十五歲)服了鈣粉+D3之後,體重回升了,鈣質對腎臟功能似乎也有幫助。 不過貓咪服用的劑量要特別注意,不要弄成高血鈣,我偶爾才給半顆(千萬不能天天給),要隨時注意愛貓走路的姿態、有無駝背傾向,曬不到太陽的一定要補充維他命D3,但這個劑量對貓而言太大,所以要特別注意!

Great value for money

Posted by 5370208073207387087 on Dec 17, 2016

This is probably one of the cheapest buy for Vit D, and it helps my nails. Small little pills make it easy to swallow. I'm waiting to see if it helps hair growth since some have reported higher doses help with that, but I'm not taking it consistently enough to say with certainty. Will update if yes.
