Is there niacin (vitamin B3) in red wine?
Red wine can contain small amounts of niacin (vitamin B3), but the amount is generally low and usually not high enough for wine to be a meaningful source of vitamin B3 for most people.
How much niacin is in red wine?
The niacin content varies by batch and brand, and nutrition panels often don’t list niacin specifically. Even when trace amounts are present, red wine is typically not comparable to foods that are known for vitamin B3 (like meat, fish, and fortified cereals).
Does “wine red” mean a specific product?
If you mean “red wine” (as in the drink), the niacin question is the same. If you mean a product labeled “Wine Red” (such as a dye or supplement) then niacin depends on the product’s ingredient list and would not be assumed from the name.
Can red wine contribute to niacin intake overall?
Because niacin amounts are small, any contribution to daily niacin intake from red wine is usually minor. People who need vitamin B3 typically rely on diet or supplements rather than wine.
Where to check niacin for a specific bottle
If you want the most accurate answer for a particular wine, check that wine’s nutrition information. Many nutrition labels for alcohol list calories and alcohol content but not vitamins like niacin, so direct values may not be available for every brand.
