I suppose it doesn't matter where it comes from as long as it is chemically the same as what we would produce by exposing ourselves to sunlight. D3 is D3 regardless where it comes from.
Toxicity: I have two vitamin books by different authors and they make recommendations based on age, just as your link does under "dose". For those under 70 it's 600 IU per day and for those over 70 it is 800 IU per day.
My personal opinion is: Going over the recommended dosage could be toxic to certain individuals, depending on their health status. It might build up to a toxic level if the person has a slow metabolism.
After getting my blood tested for D3 (I had to ask for it.) my doctor recommended a large dose. Long story short, I couldn't tolerate a large dose. The symptom I got was pressure building up in my head. I decided to trust the recommendations from my 2 vitamin books. But when I went shopping for 800 IU of D3 I found that it doesn't exist. So I ended up buying it in liquid form. The bottle comes with an eye dropper and each drop provides 200 IU.
My last blood test indicated I was low so I have now increased the number of drops to 5. That's 1,000 IU and I will be retested later this year. The funny thing is I once tried a 1,000 IU tablet and could not tolerate it. After several days it seemed to build up in my system, but the liquid form is not doing that.

Thank you for your input. Very interesting.
I guess "trial and error" will eventually lead to an improved outcome.
For now, I'm discontinuing my daily vitamins.............
My son, after consulting with a homeopathic doctor friend of his in Colorado, actually did send me the Vit. D3 you mention above...the liquid version with the little dropper. I never took them. In the goody bag were also some Indian spices, naturally good for arthritis, etc. I really don't like to take anything........but decided last year to try the vitamins I mentioned. Truthfully, my joint stiffness is worse with the sheep's wool lanolin D3. I've read that many others had the same outcome, thus went off of it..........thinking it might be building up in my system.
Some of the folks commenting had been diagnosed with underactive thyroids, common after menopause. Such a fine line between all of these supplements. I think I'll stick with getting mine from natural foods.....
As far as the D3, will try to just get it from the sunshine.......which has come out once more. It's not a "given" up here that we will have a sunny day or even a partially sunny day.......whereas you are blessed with abundant sunshine in Florida.
I have read that the fear of skin cancer for so many years now, along with massive use of Sun Block on children and adults, has led to some Vitamin D3 deficiencies.........also that it only takes from 10 minutes to 20 minutes of sunshine on exposed face or hands to be beneficial.
Thanks again.
