Nope they're not a con.Burn it afterwards.
Are they a con? Well, the vitamins you buy in a jar I mean, not vitamins as such.
However,You don't need to take them if you eat a halfway balanced diet.They only cause problems when you are deficient in them...Scurvy and nutritional blindness and god knows what else.
Also..and this I found particularly interesting....you need a whole factory to make one vitamin...and thats all it can do.You can't make C on a Monday then D on a tuesday.No way jose.
And by factory..I mean full on enormous chemical plant.So large in fact that theres not many can do it..so 80% of the worlds supply comes from a few factories in China these days..used to be teh Netherlands..and are then wholesaled to your various repackagers...to fortify cornflakes or be sold in the health shop or whatever.
Its a fascinating book altogether
