A few years ago I found out the vitamin C content of pasture or lawn grass, I can’t remember where I found it. From memory it was similar to oranges, but it was a few years ago so I could be wrong. Does anyone know how much vitamin C is in pasture or lawn grass? I know the type of grass and amount of weeds will all influence this somewhat. I am curious about this for guinea pigs who like us can not synthesize vitamin C.
