FDA Puts Caffeine Labeling on Its 2026 Agenda: What Cans Hide

WASHINGTON - Earlier this year, the US Food and Drug Administration placed draft guidance titled "Labeling Caffeine Content in Foods and Beverages" on its 2026 Human Foods Program agenda. While federal law mandates caffeine on ingredient lists when added directly, it does not require exact milligram disclosures on energy drink cans.

Key takeaways:

• The FDA placed draft guidance on its 2026 agenda to address quantitative caffeine disclosures on food and beverage packaging.
• Federal rules currently mandate caffeine in ingredient lists when added directly, but disclosing the exact milligram count remains entirely voluntary.
• The FDA notes that 400 mg per day is not generally associated with dangerous, negative effects for healthy adults, while commercial energy drinks typically contain between 41 mg and 246 mg per 12 fluid ounces.
• Regulatory pressure is building alongside state actions, such as an inquiry opened by the Texas Attorney General into Celsius Holdings in June 2026.
• Shoppers currently have to decipher different labeling rules depending on whether a beverage is sold as a conventional food or a dietary supplement.

What happened

On July 2, 2026, Food Dive reported that the US FDA updated its Human Foods Program guidance agenda for 2026 to include upcoming draft guidance titled "Labeling Caffeine Content in Foods and Beverages." The listing is a first federal step toward standardizing how caffeine is quantified on consumer goods.

Under existing federal regulations, manufacturers must declare caffeine in the ingredient statement if it is added directly as an isolated substance. However, federal law has never forced beverage makers to declare the specific milligram quantity anywhere on the Nutrition Facts or Supplement Facts panels.

This agenda update comes at a time of heightened scrutiny from public health organizations, consumer advocacy groups, and state regulators. State-level actions, including an inquiry opened by the Texas Attorney General into Celsius Holdings in June 2026 regarding its marketing and product disclosures, reflect growing concern over how high-caffeine beverages are presented to the public, particularly younger demographics.

What changed?

The planned FDA guidance will formally introduce agency recommendations on how food and beverage makers should declare caffeine concentrations. While the draft guidance is still pending publication, its inclusion on the active 2026 Human Foods Program agenda signals a shift toward explicit milligram declarations on commercial packaging.

Historically, the FDA has treated caffeine under conventional food standards (21 CFR 182.1180), which recognizes caffeine in cola-type beverages up to 0.02 percent (roughly 71 mg per 12 fluid ounces) as Generally Recognized as Safe (GRAS). However, that standard applies specifically to colas, leaving modern energy drinks, canned cold brews, and functional seltzers in a distinct category without a specific, mandatory milligram cap or uniform quantitative disclosure mandate.

If the forthcoming draft guidance mirrors standard nutritional labeling frameworks, brands may soon face uniform recommendations to publish exact caffeine levels per serving and per container. This shift would harmonize transparency between conventional energy drinks and energy beverages classified as dietary supplements.

Who is affected?

The scope of this regulatory development spans conventional beverage makers, dietary supplement brands, and everyday shoppers who consume caffeinated products. Energy drink producers, including major brands like Monster, Celsius, Red Bull, and Alani Nu, sit at the center of this transition.

Currently, energy drinks on grocery shelves fall into two distinct regulatory pathways with differing label formats:

• Conventional Foods: These carry a standard Nutrition Facts panel. If caffeine is added directly, it appears in the ingredient list, but total caffeine content in milligrams is optional.
• Dietary Supplements: These carry a Supplement Facts panel. Caffeine may be listed as part of a proprietary energy blend without an individual milligram breakdown, provided the total blend weight is stated.

Adolescents, pregnant individuals, and people with underlying cardiovascular conditions represent sensitive populations heavily affected by hidden or ambiguous caffeine levels. Clear milligram declarations help these groups monitor their daily intake and avoid accidental overconsumption across combined sources.

What it means for shoppers?

When a shopper picks up an energy drink can today, what they can and cannot see depends entirely on how the manufacturer chooses to package the product. In many cases, voluntary declarations already exist, but standard placement is not legally uniform.

When examining a can of Monster Energy or Celsius today:

• What you can see: You can verify whether pure caffeine, guarana extract, green tea extract, or taurine is present in the ingredient list. Many major brands voluntarily state the total caffeine count (such as 160 mg or 200 mg per can) on the front or back label.
• What you cannot always see: If a drink uses a proprietary herbal blend under a Supplement Facts panel, the exact split between synthetic caffeine and naturally derived caffeine from botanical extracts like guarana or yerba mate may be concealed.
• What the guidance would change: Standardized guidance aims to establish consistent milligram disclosures directly on the nutritional panel, eliminating the need to hunt through marketing copy or calculate multi-serving tallies.

Shoppers should also note that dietary variables create vast differences in individual tolerance. One major uncertainty in nutritional science is individual caffeine metabolism, which is influenced by genetic variations in the CYP1A2 liver enzyme and cannot be predicted simply by reading a label.

The background

Federal oversight of caffeine has evolved through a patchwork of food additive rules, advisory updates, and targeted safety enforcement. According to official consumer guidance from the FDA, up to 400 milligrams of caffeine per day is not generally associated with dangerous, negative effects in healthy adults.

Despite this adult threshold, commercial energy drinks typically contain between 41 mg and 246 mg of caffeine per 12 fluid ounces, according to regulatory data. Consumers must check the Nutrition Facts panel or verified manufacturer label disclosures to determine the specific milligram count for a given container, as individual brand formulations vary widely across product sizes.

In recent years, the FDA took strong enforcement action against bulk pure and highly concentrated caffeine powders and liquids under dietary supplements guidance, deeming them adulterated due to the severe risk of accidental lethal overdose. However, RTD (ready-to-drink) packaged energy drinks remained governed by general food labeling standards.

State-level initiatives such as New York's Food Chemical Disclosure Act and Texas' paused 44-ingredient warning label have intensified the focus on ingredient transparency across the beverage industry.

What to watch next

The agenda lists the caffeine labeling document as a priority but gives no release date. Once the draft is published, it will open a public comment period in which food scientists, beverage manufacturers, and health advocates can submit formal feedback.

Key developments to monitor include:

• The specific threshold at which quantitative milligram labeling is recommended across different food and beverage categories.
• Whether the guidance provides specific recommendations for multi-ingredient energy blends containing naturally caffeinated botanicals like guarana and kola nut.
• How manufacturers adapt packaging design and panel placement ahead of finalized federal standards.
