Sorry I didn't make myself clear Steve. The point I was making was;
these vitamins are water soluable, therefore the more H2O you excrete,
the more vitamins B&C you excrete. Liquids with a mild diuretic will
slightly increase this rate of excretion. However, the rate increases
sharply if you are a heavy coffee or tea drinker, simply because you
have to pee more and therefore deplete your bodys' stores of B&C sooner.
