i'm getting widely divergent estimates. if a pea-sized amount is 25 mg, i'm using roughly 50 mg, which is only .05*.005 = .00025 g, in the end - half as much as a glass of water.
but, some estimates suggest that the average person uses as much as a gram of toothpaste at a time, which would be .005 g, or 5 mg, if i swallowed it directly. that's higher than the fda's rdi and could conceivably produce a reaction, for sure.
another number i've seen is 400 mg, which is .4*.005 = 0.002 g = 2 mg.
well, why don't i just take it in two doses, to be sure, until i can get a better measurement? i'm feeling something, and should ultimately react to that more than anything else....
