Vitamin D has helped against colds

Posted by iHerb Customer on Nov 20, 2017 | Verified Purchase

I have taken vitamin D during four years and during that time I have had only one really bad cold. Before that I used to have a few colds per year and frequent bladder infections. Other people around me sneeze, but I don´t get their virus. That saves me lots of money and it increases the quality of my life. This product contains 5000 IU = 125 micrograms of vitamin D, it´s a bit more than the recommended max dose of 100 ug/day, so I can take it 5 times/week instead of daily.

Sticking capsules

Posted by iHerb Customer on Nov 13, 2017 | Verified Purchase

For a long time I have bought this brand and without problems. But when I opened this batch all the capsules were sticky and I could not take them apart. I need a new batch asap. Best regards, Ole

Vitamin D3 by Doctor's Best, no complaints

Posted by iHerb Customer on Nov 09, 2017 | Verified Purchase

I take three vitamin D3 tablets per day. I can't tell how effective they have been, as I don't feel any better or worse. But with the extensive amount of studies and research being done on the benefits of Vitamin D3 for people living in cold northern climates, I will continue to take it. This product leaves no aftertaste, and are a good size and easy to swallow.
