What is the percent daily value of vitamin B-12?

The percent daily value of vitamin B-12 is often set based on dietary recommendations for the average adult. In many nutrition guidelines, the daily value for vitamin B-12 is established at approximately 2.4 micrograms per day. When foods are labeled, the percent daily value indicates how much a serving of food contributes to the total daily diet, based on a 2,000-calorie diet.

In this context, the choice suggesting an 8% daily value corresponds to a food item containing about 0.2 micrograms of vitamin B-12 per serving. This amount represents 8% of the daily recommended intake, which can commonly be found in various vitamin or mineral supplement facts labels.

Understanding the percent daily values helps consumers gauge how much of the nutrient they are consuming in relation to their overall dietary needs and allows for easier comparisons between different food products. This is especially important for vitamins such as B-12, which are crucial for energy production, nerve function, and the formation of red blood cells.
