>> "Look at vitamin C, D3 and Iodine for example. The RDA for vitamin C is the minimum amount needed to prevent scurvy! We should all be looking at optimum daily amounts - and it would be nice to have that differentiated between natural and supplemental forms." <<
my guess is that the D3 through a clean, high quality diet and outdoor living would be enough.
Vitamin C; I have no idea what a sailor's lime or lime juice ration was, however a lime has about 1/2 RDA... a lemon is about RDA...
I had 4.5, organic, high brix, home grown lemons today and was in the sun for over 8 hours.
Which brings me back to - how much do we really need? And why are we not protesting the poor food quality?
