Beer contains small amounts of several B vitamins, mainly B6, B9, and B12, but not in significant quantities to meet daily needs.
The Presence of Vitamin B in Beer
Beer is a popular alcoholic beverage enjoyed worldwide, but its nutritional profile often raises questions. One common query is: Does beer have vitamin B? The answer is yes, but with important caveats. Beer does contain some B vitamins because it’s brewed from grains like barley and wheat, which naturally carry these nutrients. Moreover, the yeast used in fermentation contributes to the vitamin content.
However, the actual amounts of vitamin B in beer are generally low and vary depending on the type and brewing process. The primary B vitamins found in beer include vitamin B6 (pyridoxine), vitamin B9 (folate), and traces of vitamin B12 (cobalamin). These vitamins play crucial roles in energy metabolism, red blood cell formation, and nervous system function.
Despite this presence, drinking beer as a source of vitamin B is not efficient or recommended due to alcohol’s negative effects on nutrient absorption and metabolism. Still, understanding what types of vitamin B are present and their approximate levels can give a clearer picture of beer’s nutritional value.
Which B Vitamins Are Found in Beer?
The group of eight vitamins known as the B-complex includes thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9), and cobalamin (B12). Not all these vitamins appear equally in beer.
Vitamin B6 (Pyridoxine)
Vitamin B6 shows up most prominently in beer. It assists in amino acid metabolism and neurotransmitter synthesis. The yeast involved in fermentation synthesizes some pyridoxine, which remains partly intact after brewing.
Vitamin B9 (Folate)
Folate is essential for DNA synthesis and repair. It is naturally present in cereal grains used for malt production. Although some folate degrades during brewing due to heat exposure, measurable amounts remain.
Vitamin B12 (Cobalamin)
Vitamin B12 typically comes from animal sources; however, trace amounts can be found in unfiltered beers that contain active yeast sediment. These amounts are very small and unreliable as a dietary source.
Other B Vitamins
- Thiamine (B1) is usually destroyed during brewing because it’s heat-sensitive.
- Riboflavin (B2) may be present but often at low levels.
- Niacin (B3) can survive the brewing process moderately well.
- Pantothenic acid (B5) and biotin (B7) are present only in minor traces.
B Vitamin Content Comparison per 12 oz Beer Serving
To put things into perspective, here’s a table comparing approximate amounts of key B vitamins found in a standard 12-ounce serving of typical lager beer against daily recommended values for adults:
| B Vitamin | Amount per 12 oz Beer | % Daily Value* |
|---|---|---|
| Vitamin B6 (Pyridoxine) | 0.1 mg | 5% |
| Folate (Vitamin B9) | 15 mcg | 4% |
| Niacin (Vitamin B3) | 1 mg | 6% |
| Riboflavin (Vitamin B2) | 0.05 mg | 4% |
| Cobalamin (Vitamin B12) | <0.1 mcg* | <2% |
*Based on average adult daily values: Vitamin B6 = 1.3 mg; Folate = 400 mcg; Niacin = 16 mg; Riboflavin = 1.3 mg; Vitamin B12 = 2.4 mcg.
This table demonstrates that while beer contains some vitamin Bs, it provides only minor fractions of daily requirements.
The Role of Yeast in Vitamin Content
Yeast plays a pivotal role not only during fermentation but also as a nutrient source within beer itself. Brewer’s yeast contains significant amounts of various vitamins including those from the vitamin B complex group. However, most commercial beers undergo filtration processes that remove much of the yeast sediment before packaging.
Unfiltered or “craft” beers tend to retain more live yeast cells and thus higher levels of certain nutrients like vitamin B12 and folate compared to filtered lagers or pilsners. Some specialty beers even advertise their rich nutrient profiles due to high yeast content.
Still, even unfiltered beers offer only modest contributions to daily vitamin needs because alcohol metabolism interferes with nutrient absorption overall.
The Impact of Alcohol on Vitamin Absorption
Alcohol consumption complicates the picture when discussing whether beer supplies useful amounts of vitamin Bs. Ethanol interferes with the digestion and absorption of many nutrients including water-soluble vitamins like those from the vitamin B family.
Chronic alcohol intake can lead to deficiencies by:
- Reducing intestinal absorption: Alcohol damages the gut lining impairing nutrient uptake.
- Affecting liver function: The liver metabolizes vitamins; excessive drinking hampers this process.
- Increasing excretion: Alcohol acts as a diuretic causing loss of water-soluble vitamins through urine.
Therefore, even if beer contains some vitamins naturally, relying on it for nutrition is counterproductive because alcohol itself depletes these essential nutrients faster than they can be replenished.
Nutritional Differences Across Beer Types
Not all beers are created equal regarding their nutritional makeup:
Lager and Pilsner
These clear filtered beers generally have lower residual yeast content resulting in less vitamin retention overall. They still offer small amounts but tend toward minimal contributions.
Ale and Stout
Dark ales or stouts often undergo less filtration leaving more suspended yeast particles behind which can boost certain vitamins slightly—particularly folate and riboflavin.
Cask-conditioned / Unfiltered Beers
These beers hold live yeast sediment making them richer sources for some water-soluble nutrients including specific Bs like biotin or cobalamin found rarely elsewhere in plant-based sources.
Despite these variations though, none provide enough vitamin Bs to replace balanced dietary sources like leafy greens, meats, dairy products or fortified cereals.
The Broader Nutritional Profile of Beer Beyond Vitamin Bs
While focusing on whether beer has vitamin B is important for understanding its nutritional value, other components also deserve attention:
- Minerals: Beer contains potassium, magnesium, phosphorus along with trace minerals beneficial for health.
- B Vitamins Synergy: Small quantities work together with other nutrients supporting energy metabolism.
- Calories & Carbohydrates: Beer provides energy mainly through alcohol content plus residual sugars.
Still again – moderation matters! The calories from alcohol add up quickly without delivering substantial nutrition compared to whole foods rich in vitamins and minerals.

Frequently Asked Questions
Does Beer Have Vitamin B6?
Yes, beer contains vitamin B6, also known as pyridoxine. This vitamin is involved in amino acid metabolism and neurotransmitter synthesis. The yeast used in fermentation produces some B6, which partly remains after brewing, making it the most prominent B vitamin in beer.
Does Beer Have Vitamin B9 (Folate)?
Beer does contain vitamin B9 or folate, derived from cereal grains used in malt production. Although some folate is lost during the brewing process due to heat, measurable amounts remain in the final product, contributing modestly to your folate intake.
Does Beer Contain Vitamin B12?
Trace amounts of vitamin B12 can be found in unfiltered beers that contain active yeast sediment. However, these quantities are very small and unreliable as a dietary source since B12 primarily comes from animal-based foods.
Does Beer Have Other B Vitamins Besides B6, B9, and B12?
Beer may contain small levels of other B vitamins like riboflavin (B2) and niacin (B3). However, thiamine (B1) is usually destroyed during brewing due to heat sensitivity, and vitamins like pantothenic acid (B5) and biotin (B7) appear only in minor amounts.
Is Beer a Good Source of Vitamin B?
While beer does have some B vitamins, the amounts are generally low and insufficient to meet daily nutritional needs. Additionally, alcohol can negatively affect nutrient absorption and metabolism, so beer is not recommended as a reliable source of vitamin B.
The Bottom Line – Does Beer Have Vitamin B?
Yes—beer does contain various members of the vitamin B complex primarily thanks to its grain base and fermentation by yeast cells. But these quantities are quite modest relative to recommended daily intakes. The real kicker? Alcohol interferes with your body’s ability to absorb these vitamins effectively making beer an unreliable source for fulfilling your nutritional needs.
If you’re looking for ways to boost your intake of vital Bs like folate or pyridoxine—turn toward whole foods such as leafy vegetables, nuts, seeds, legumes, eggs or fortified products instead. These options supply ample amounts without adverse effects linked with alcohol consumption.
In summary:
- Beer offers minor amounts: Mainly vitamins B6 and folate.
- Nutrient levels vary: By type—unfiltered has more than filtered varieties.
- Ethanol reduces benefits: Alcohol impairs absorption & increases excretion.
Enjoying a cold brew now and then won’t hurt your vitamin balance but don’t count on it as a meaningful source for keeping your body fueled with essential nutrients like vitamin Bs!
