A new study finds that beer contains substantially more vitamin B6 than previously estimated, with one standard serving providing about 15% of daily needs.
Researchers analyzed 65 German beers using updated lab techniques
The study, published in the Journal of Agricultural and Food Chemistry, measured vitamin B6 levels in commercially available beers and found concentrations ranging from 95 to over 1,000 micrograms per liter.
Bock beer showed the highest vitamin B6 content among tested styles
Bock beer averaged approximately 808 micrograms per liter, while classic lagers averaged around 515 micrograms per liter, and wheat and rice beers had the lowest levels.
Barley malt is the primary driver of vitamin B6 variation in beer
Researchers determined that ingredient composition, particularly the use of barley, had a greater impact on B6 levels than brewing technology, with barley containing nearly four times more B6 than rice.
Alcohol removal does not significantly affect vitamin B6 retention
The study found no meaningful difference in B6 content between regular lager and its non-alcoholic equivalent, indicating that de-alcoholization processes preserve the vitamin.
Vitamin B6 deficiency remains a public health concern in Europe and the U.S.
About one in five European adolescents and one in ten Americans have insufficient B6 levels, which have been linked to depression, cardiovascular disease, and inflammation.
What is vitamin B6 and why is it important?
Vitamin B6 is an essential nutrient that the body cannot produce on its own and supports brain function, blood health, and immune system activity.
Can drinking beer replace other dietary sources of vitamin B6?
No, while beer contributes to B6 intake, it should not replace a balanced diet rich in other B6 sources like poultry, fish, potatoes, and fortified cereals.
