A US "nickel" five-cent coin weighs exactly five grams. I always thought that this is a tiny amount, the weight of just five milliliters of water. It did not make sense to me in the past that such a small amount of something the body needs would cause gastrointestinal distress in such a tiny amount, those five grams for me even in a 12 oz glass of juice would wreak havoc. I just "knew" there had to be a way, It sure took me forever, sheesh. At least I can stop thinking about it finally, one less thing on my mind
