How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

    **Human breath measurements.** Lawson and Hunsaker compared preparations using thirty-two-hour breath allyl methyl sulfide (AMS) exposure in thirteen participants. Their relative results were 80–111% for tested non-enteric tablets, 36–104% for enteric tablets, and 22–57% for enteric products with high-protein meals, relative to homogenized raw garlic. These percentages are not absolute bioavailability of intact plasma allicin. The study also found contributions from SAC-related precursors to AMS, particularly relevant to preparations with inhibited alliinase. Thus AMS is a useful preparation-comparison marker with chemical-origin limitations. Enteric coating is not automatically superior. Meal effects, disintegration, enzyme activity, and the assay all matter. [Lawson and Hunsaker 2018](https://pmc.ncbi.nlm.nih.gov/articles/PMC6073756/)
