Forms Comparison

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