Overview
- The peer‑reviewed study, published Wednesday in ACS’ Journal of Agricultural and Food Chemistry, measured vitamin B6 across 65 beers using a validated isotope‑dilution LC–MS/MS method.
- Bock beers contained the most vitamin B6 at 808.2 micrograms per liter, while rice beers ranked lowest among the styles tested.
- Alcohol‑free and regular lagers showed no meaningful difference in B6 levels, and NA beers kept more B6 when ethanol was removed after full fermentation rather than using low‑alcohol yeasts.
- Based on the samples, an average lager provided about 20% of the U.S. recommended daily allowance for B6, and one NA lager delivered nearly 59%, giving consumers a nonalcohol choice with notable B6.
- The authors disclosed funding from the Scientific Association for Brewing in Munich, a detail relevant for readers assessing potential industry influence on the research.
