Inside the Lab: How 65 Supermarket Beers Measured Up
A recent scientific study examined 65 different beers bought from local supermarkets and ranked them by vitamin B6 content. The researchers focused on ingredients typical to beer—barley, wheat, and brewer’s yeast—and confirmed that these remain meaningful dietary sources of vitamin B6 even after brewing. One style clearly stood out: bock, a traditional lager known for its toasty, caramel character, showed the highest levels of the vitamin. Following bock, other lager styles such as pilsners and helles also provided relatively high amounts, then dark lagers, wheat beers, and finally beers brewed with rice in the grain mix. Importantly, the team also compared alcoholic and non-alcoholic versions. Contrary to their initial concerns, removing alcohol did not significantly reduce vitamin B6 overall, opening the door to viewing some non-alcoholic beers as potentially functional beverages from a nutrient perspective.
Vitamin B in Beer: What It Does in Your Body
Vitamin B in beer is mostly about vitamin B6, a nutrient linked to brain health, blood formation, immune function, and energy metabolism. Men are advised to get about 1.4 mg per day and women 1.2 mg, according to public health guidance cited in the study. The researchers found that one litre of beer contained between 0.3 mg and 1 mg of vitamin B6, and an average lager provided around 20% of the recommended dietary allowance. One non-alcoholic lager tested reached nearly 59% for vitamin B6, underscoring how some products can be surprisingly rich in this nutrient. While beer can also contain other B vitamins derived from malt and yeast, the study focused on B6 because of its well-documented links with cardiovascular health, mood, and inflammation. Still, scientists stressed that these findings are primarily useful for people who intentionally want to optimise their vitamin intake.
Why Some Beer Styles Pack More B Vitamins Than Others
The study’s results highlight how beer style and production choices can influence vitamin B in beer. Bock, pilsner, and helles lagers topped the vitamin B6 charts, likely because of their grain bill and how they are fermented and conditioned. Dark lagers and wheat beers followed, while beers brewed with rice showed lower levels. The research also uncovered a key detail about non-alcoholic styles: those brewed with a full fermentation and then de-alcoholised tended to have higher B6 than versions made with special yeasts that produce less alcohol. That suggests process matters as much as ingredients. In practical terms, beers that retain more yeast or undergo fewer aggressive filtration steps may preserve more B vitamins. However, even healthier beer styles vary widely, and nutrient levels depend on the specific recipe and brewing method, not just the label on the can or bottle.
Beer Is Not a Supplement: Sorting Out Health Claims
Although the lab results on B vitamins and alcohol-free options are intriguing, they should not turn beer into anyone’s daily supplement strategy. To reach the higher vitamin B6 values reported in the study—up to 1 mg per litre—you would still need to consume substantial volumes, and alcoholic beer brings obvious downsides: extra calories, intoxication, and long-term health risks. The researchers themselves emphasised that their findings are only truly useful for consumers who are already trying to optimise their vitamin intake, not an invitation to drink more. Non-alcoholic lagers with good vitamin B6 levels may fit more logically into a balanced diet, but even then, they should be considered an occasional beverage, not a primary nutrient source. For most people, foods like meat, fish, oats, potatoes, and chickpeas remain more practical and reliable ways to meet daily B vitamin needs.
Practical Takeaways for ‘Better for You’ Beer Choices
For drinkers curious about healthier beer styles and beer nutrition facts, the study offers some grounded guidance without overpromising. First, if vitamin B6 is on your radar, lager styles such as bock, pilsner, and helles appear to deliver more than many rice-based beers, with dark lagers and wheat beers contributing meaningful amounts as well. Second, non-alcoholic lagers that have had their alcohol removed after a full fermentation may retain particularly high B6 levels, making them an interesting choice for people seeking unfiltered beer benefits without intoxication. Still, it is wise to treat b vitamins in alcohol as a small bonus, not the main attraction. Focus on moderation, check serving sizes, and view any nutrients in beer as secondary to your overall diet. Beer can be enjoyed thoughtfully, but it should never replace diverse, nutrient-dense foods.
