This is all true but science can be used for good OR evil so people have to do their own research and determine their own answers so they can make well-informed decisions concerning their own health. Unfortunately science has been used to cause many disastrous situations for people. When people and money or power are involved it can be very bad for uninformed people. I actually love medicine and science but I hate the lies and abuses that have been perpetuated in the name of science or medicine. With the information available to people today there really is no excuse for ignorance.

Your statement about sunshine is best for Vitamin D is only valid for those able to absorb it properly. Otherwise it is wise to recognize the problem and supplement. My sister was schizophrenic but megadoses of B3 made her able to live normally. Things are just not always hard and fast. The people that set vitamin limits don't have a clue about vitamins and safe doses because they usually have a vested interest in making money off of drugs. We now see population control and other factors also dictate what info is given. .

I somehow agree with all three of you. :)

1. Can you overdose on D? Well of course you can.
2. Is it likely you will manage to do that with over-the-counter tablets? No. Not unless you are eating half a bottle a day. :)

I think if my tinfoil hat is on correctly, "they" constantly mention the threat of ODing to scare people away from supplementing with D. Because they are ghouls who want you dead.

So take ~10,000 IU a day of good (non-China) Vitamin D, get out in the sunshine between 10PM and 3PM for ~30 mins a day, get yourself tested to know your level, and try to eat some oily fish and eggs as much as you can.
