Correcting the Misconception: The Story Behind Vitamin A and C on Food Labels
A common myth suggests that vitamins A and C have been removed from the official list of micronutrients. This claim is based on a misunderstanding of a significant update to the Nutrition Facts label by the U.S. Food and Drug Administration (FDA) in 2016. In reality, these vitamins remain crucial for human health, and their essential status has not changed. The change simply reflects shifts in public health priorities and nutritional science over the last few decades.
The FDA's Reasoning for the 2016 Label Change
The 2016 update to the Nutrition Facts label was the first major revision in over 20 years, intended to reflect modern scientific understanding and help consumers make better food choices. A key driver for removing vitamins A and C from the mandatory list was that widespread deficiencies, once a serious public health concern, had become increasingly rare in the United States. The FDA shifted focus to nutrients where deficiencies are more common today, or those with strong ties to chronic disease risk. The agency wanted to highlight nutrients most relevant to the current population's health.
The updated label now requires manufacturers to list vitamins D and potassium, in addition to calcium and iron. This change was based on scientific evidence showing that Americans typically do not get enough of these nutrients, increasing the risk for issues like osteoporosis and high blood pressure. The removal of vitamins A and C from the required list does not prevent food manufacturers from voluntarily including them on the label, especially if their product is a particularly good source.
The Enduring Importance of Vitamins A and C
Despite their removal from mandatory labeling, vitamins A and C are as vital as ever. Their physiological roles are extensive and non-negotiable for human health. The idea that they are no longer important is a dangerous piece of misinformation.
The Functions of Vitamin A
- Vision: Vitamin A is critical for good eyesight, particularly night vision.
- Immune System: It plays a vital role in the function of the immune system and helps to maintain the integrity of epithelial tissues that act as a barrier against infection.
- Growth and Reproduction: This micronutrient is essential for proper growth and development, as well as for reproductive health.
The Functions of Vitamin C
- Antioxidant Power: Vitamin C is a powerful antioxidant that protects the body's cells from damage by free radicals.
- Collagen Synthesis: It is a key cofactor for collagen synthesis, a protein necessary for healthy skin, bones, tendons, and blood vessels.
- Iron Absorption: Vitamin C significantly enhances the absorption of non-heme iron from plant-based foods.
Comparison: Old vs. New Nutrition Facts Label
| Feature | Old Nutrition Facts Label (Pre-2020) | New Nutrition Facts Label (Post-2020) |
|---|---|---|
| Serving Sizes | Based on consumption habits from decades ago. | Updated to reflect modern consumption patterns. |
| Calories from Fat | Mandatory listing. | Removed, as the type of fat is more important than the amount. |
| Added Sugars | Not explicitly required. | Added to the label to help consumers identify how much sugar is added to a product. |
| Vitamin A & C | Mandatory listing, shown as a percentage of Daily Value. | Voluntary listing; not required due to rarity of deficiencies. |
| Vitamin D & Potassium | Voluntary listing. | Mandatory listing; required due to common deficiencies. |
| Footnote | Provided general dietary advice about calorie consumption. | Updated to provide a more specific explanation of the % Daily Value. |
Why Did the Misinformation Spread?
The confusion primarily stems from a misinterpretation of the FDA's label change. When the new food labels began appearing in stores, some people noticed the absence of vitamins A and C and mistakenly concluded they had been demoted in nutritional importance. This created fertile ground for misinformation to spread online, amplified by claims that the government or corporations were hiding information. This type of health misinformation is a growing problem, often twisting factual events (like a label change) into pseudoscientific narratives. It is a prime example of why sourcing health information from reliable, authoritative sources like the FDA and established health institutions is so critical.
The Bottom Line
To be perfectly clear, vitamin A and C are still essential micronutrients. They have simply been removed from the mandatory reporting section of the U.S. Nutrition Facts label, a change implemented by the FDA to better reflect current public health needs and provide consumers with more relevant information about nutrient deficiencies that are common today. A balanced diet rich in a variety of fruits and vegetables remains the best way to ensure adequate intake of all micronutrients.

Conclusion
The tale of vitamins A and C on the nutrition label is not one of a nutritional downgrade, but of public health progress and policy updates. The FDA's decision to make these listings voluntary is a positive sign that widespread deficiencies for these specific nutrients are no longer a major concern in the U.S. population. The change prioritizes information about nutrients that are more commonly lacking, helping consumers make better-informed decisions. While the label may have changed, the fundamental nutritional importance of vitamins A and C has not, and they remain critical for maintaining overall health.
