Forms Comparison

FormBioavailabilityBest For
Tributyrin CapsulesHigh (colon-targeted)Optimal delivery — survives stomach acid, releases butyrate in the colon where it is needed
Sodium Butyrate CapsulesLow-Moderate (releases in stomach)Budget option — cheaper but most butyrate is absorbed before reaching the colon; strong odor
Calcium/Magnesium ButyrateModerateMineral-buffered — slightly delayed release compared to sodium butyrate, with added mineral content
