There was a reason for my statement BE WARNED I DO NOT TREAT FOOLS KINDLY
In my opinion only a fool would put a warning on a tap saying "Be very careful with water, it is easy to overdose and potentially dangerous in high doses in the body"
Yes we know that lots of people drown each year because of water and we know that pyschotic individuals can drink water obsessively and die of water intoxication but COMMON SENSE and the ability to do mental arithemetic enables us to work out the risk of danger from drinking water and compare that with the amount needed for healthy living.
8 glasses a day of water is generally regarded as a safe sensible amount
40 glasses a day of water would lead to problems and could kill you.
the ratio of safety over danger is 5
You would need to take five times the safe amount of water to harm yourself.
Although the OFFICIAL RDA for Vitamin d is 400iu the IDEAL OPTIMUM AMOUNT that allows you to retain the safe vitamin d status your body naturally obtains from regular limited non burning exposure to sunshine is 4000iu a day.
SO
the latest research proves 4000iu is the ideal amount daily for optimal health
The amount that MAY lead to health problems if sustained on a daily basis for a period of MANY MONTHS is 40,000iu/daily
The therapeutic index of safety over danger is TEN 10
So which is the most dangerous?
Water with a therapeutic index of 5 or Vitamin d with a therapeutic index of 10?
The kind of mentality that puts warnings on packs of cashews reading "MAY CONTAIN NUTS" or on Cheese "MAY CONTAIN MILK" is like the previous poster. Perhaps they would find their time making a fool of themselves by putting up notices round the desert saying "Danger of Drowning".
The calculator
here shows if you can get Vitamin D from sunshine on any particular day of the year and given the current cloud/pollution constraints. If sunshine is available at midday, when the ratio of UVB<>UVA is optimal for vit d synsthis, then clearly there is NO need to use supplements and you can spend 20 mins in the sunshine and make it for free. Doing this 3 times a week will supply roughly 30,000iu Cholecalciferol sufficient for 7 days use at 4000iu/d
For those who are unable to go outside during the day taking this amount of vitamin d is TWICE as safe as drinking the Optimum amount of water. It is ONE TENTH of the amount needed (over a long period of time) may hurt you.
Restoring physiological serum levels of 25(OH)D will help many more patients than it will hurt.
In fact, living in America today while worrying about vitamin D toxicity is like dying of thirst in the desert while worrying about drowning.
So if CARLA wants to start putting "danger of drowning" notices round the nearest desert she would be far better employed doing that than displaying her lack of understanding and gullibility here.
