Your pint could come with a surprising health benefit

A recent study reveals that a single pint of beer may contribute significantly to your daily intake of vitamin B6, as researchers note. This essential nutrient supports brain function, blood health, and immune response, and is naturally present in various foods. The analysis of 65 German beers, purchased from local supermarkets, indicates that a litre of beer can contain between 0.3mg and 1mg of B6. While this range falls short of meeting daily requirements for a vitamin label, it still represents a notable amount.

Beer’s B6 Content and Ingredients

Raw components used in brewing, such as barley, wheat, and brewer’s yeast, are rich in B6. The study suggests that the production process does not entirely eliminate this vitamin. For instance, traditional German bock beer, with alcohol content starting at 6.5%, showed the highest B6 levels among the tested varieties. Alcohol-free lager also retains a similar amount, according to the research.

Expert Perspectives on B6 Intake

“We wouldn’t suggest that beer or any alcoholic drink is a primary source of nutrients. That should come from diet,” says Bridget Benelam of the British Nutrition Foundation. She adds that complete B6 deficiency is uncommon in the UK, as the nutrient is widely available in foods like meat, fish, porridge oats, potatoes, and chickpeas. Many breakfast cereals also fortify B6.

Benelam highlights that while B6 levels in beer are measurable, they are not sufficient to classify it as a key nutrient source. She recommends focusing on other B vitamins, such as B12 and riboflavin (B2), which are typically found in dairy and animal products. For vegans, fortified plant-based alternatives like milk and yogurt substitutes are advised to ensure adequate intake.

Considerations for Specific Health Conditions

Prof Michael Rychlik, the study’s lead author, emphasizes that the findings are most relevant for individuals aiming to maximize their vitamin consumption. However, he notes that even within recommended alcohol limits, beer’s B6 contribution is not enough to warrant a vitamin label. Deficiency in B6 is rare, though it can occur alongside a lack of other B vitamins, such as B12, leading to symptoms like fatigue and nausea.
