Been using these for years. I take two a day which brought my level of Vitamin D up from 28 to 65. Taking the Vitamin D2 the doctor prescribed for three years did not bring my levels up but this one did. It's a D3.

This is exactly what it says on the bottle, and is effective at raising plasma D3 levels
It's Vitamin D from a reputable brand. It did what it was supposed to do, and after a couple of rounds my blood labs showed me as much. I won't speak too much to its other effects, but I did live in the Pacific Northwest, was used to a regular seasonal depressive fugue. To my surprise I did not have that experience while on this supplement.

We have used quite a lot of Doctor's Best products over the years. The one thing they all have in common - high quality. When it comes to supplements I don't want to chance anything with a cheap inferior product. Not that Doctor's Best is expensive, in fact, I often see their products as being the more economical option. In regards to the Vitamin D3, my husband had a pretty big deficiency, and after taking these every day his tests have come back in the normal range. Tiny gel caps, very easy to swallow with virtually no taste at all.
