Hey bignumber5, thank you for your contribution to this and yes i would quite agree that high levels of any fat soluble vitamin could be bad over a long period of time, however these experts are claiming, with the new research, that Vitamin D3 is essential in human health, the website that you are quoting from mentions Vitamin D and in many cases trials are in labs and old school. ( I hear Huguenot coming to ask for stats). I am researching this for personal reasons and know 2 people that are taking 20 000 IU's daily and they feel great, happy and have no cold symptoms to date. I on the other hand have a stinking cold so maybe i should be taking this myself now. Not disagreeing with what you have posted as all opinions are welcome but nobody yet has come forward stating whether they are taking this Vitamin in particular, for research purpose. Big American supplement companies are manufacturing high dose D3 supplements. KK, good mate, i will explain this when i see you as it's a bit long winded. DM, no need to bat your eyelashes, i have stated in the past that i am a local businessman, and own several properties on LL and suurounding areas and like to contribute to the community, I don't have choc loads of Vit D supplements as you have suggested but if you are feeling a bit sad i can probably get a free bottle for you if you play nice. Thank you and good night.:)
