How fast you clear caffeine

How fast you clear caffeine is a genetic trait Biome reports in its food & drink panel: Whether you tend to clear caffeine from your blood faster or slower than average — a tendency only, not a measurement of your caffeine sensitivity. The variant is common in European-ancestry groups and close to absent elsewhere, so it carries information only there.
