I take 3-4 Vit D3 softgels per day and I want to continue doing so because I do not get that much sun. I believe it is doing what it promises.

Thanks for your feedback!

D3 is just one of the 'people' vitamins i give my 13.5 yr old dog for his arthritis. I know this brand works because I take D3 x 5,000 for myself and my bone scans are great.
