    Intrinsic Factor Supplement

    It'l work, they used this porcine intrinsic factor from the 40's-60's until they massed produced b12 more cheaply. If your methylmalonic acid and homocysteine and b12 ( saturated+ect) all test normal then you dont need it though.

    Intrinsic Factor Supplement

    http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2166340/pdf/brmedj02396-0045.pdf mean output was 2,200 units 4,400 units IF per mcg b12 absorbed, translates to 50mcg b12 absorbed per 20mg IF dose. so 10-300mcg range, with 50mcg likely at 20mg dose.

    Intrinsic Factor Supplement

    normal b12 max absorption of 1.5 mcg per 3hrs, at normal 10,000 units hour: 1mcg b12 per 20,000 units IF or 2mg IF. so maybe 10mcg b12 from 20mg IF. but its only an estimate. so as low as 10mcg b12 absorption as a floor? 300mcg a ceiling?
