Siegel, 1961): Absorption tests with food, using a flushing vitamin B12 injection to estimate absorption, indicate a reduction of the passive absorption by about 40% when supplements are taken with food rather than when fasting

None of the seven peptides is an FDA-approved drug, and the vote did not change that for any of them
They are smaller than proteins and often serve as messengers between cells
