Excellent Choice!

Posted by iHerb Customer on Apr 03, 2011 | Verified Purchase

I can't say enough good things about NF (natural factors). After meeting Dr.Murray (ND), one of the formulators for NF products, I was impressed by his philosophy on health - supplementation - botanical/natural approaches to health, and I have been purchasing NF products ever since. I dose at around 15-20K IU daily, and prefer the 5000 IU x 120 softgels because they last longer. I do recommend that if you're unsure about how much VitD3 you require, or are lacking, go get it tested by your doctor - any MD, ND, DC, or DO (etc) can facilitate this for you. Enjoy, good luck!

Thanks for your feedback!

Trusted brand, keeps my D3 blood levels high

Posted by iHerb Customer on Jan 05, 2014 | Verified Purchase

I take this all autumn and winter while the sunlight levels are low to keep my D3 levels high. According to my blood tests, it seems to be working!

Thanks for your feedback!

Good Product

I like the fact this is a soft gel. This is a good company, I use a lot of their products. I do not get colds as long as I take D3.

Thanks for your feedback!

great product and great price. Natural Factors makes a really good quality product without a lot of extra additives.

Thanks for your feedback!

I love the Natural Factors products. I was found to be deficient in Vitamin D (and living in the Northeast we can't get enough from the sun from about Oct - Mar). I've been taking this for quite a while.

Thanks for your feedback!

Vitamin D3 5000

Posted by iHerb Customer on Mar 14, 2011 | Verified Purchase

my husband and I both find D3 5000 very helpful. We recommend the vitamin and to friends here in the UK because we both trust the brand, Natural Factors, and the price, even including postage, packaging and any extras HM Government decides to add, is still advantageous.

Thanks for your feedback!

Great potency/price

Posted by iHerb Customer on Nov 17, 2010 | Verified Purchase

I really like Natural Factors brand, they are quality and the 5000iu of Vitamin D3 is a great product and price. I can tell when I don't take my vitamin D, it's good for so many things!

Thanks for your feedback!
