Functional foods designed to promote relaxation, better sleep, and improved mood have exploded in popularity, and chocolate is increasingly the delivery method of choice. Calming confections featuring ingredients like melatonin, L-theanine, magnesium, adaptogens, or CBD are marketed as “natural” stress-relievers or sleep aids. But as consumer demand rises, so too does regulatory scrutiny. Federal and state regulators, along with the plaintiffs’ bar, are watching closely as food companies make increasingly bold wellness claims about everyday indulgences.
At the heart of the issue is whether these products can legally be marketed as conventional foods when the claims they make may imply therapeutic intent or pharmacological effects. Manufacturers face growing legal risk if their labeling or promotional materials suggest that a product can treat or prevent conditions like insomnia, anxiety, or mood disorders. In particular, ingredients like melatonin and CBD are subject to specific federal restrictions, while even less controversial ingredients such as L-theanine must be backed by sound scientific substantiation when used to support mood or sleep claims.
The Challenge of Classification and Intended Use
The first challenge is classification. Under federal law, a product’s regulatory status depends not just on its form, but on its intended use. The U.S. Food and Drug Administration (FDA) evaluates intended use by examining marketing statements, consumer messaging, and even design elements of packaging. If a chocolate bar is advertised to help consumers fall asleep faster or improve mood, it may be considered a drug unless the claim fits within the structure/function framework that applies to foods or supplements. Even claims like “promotes relaxation” or “helps reduce everyday stress” may trigger heightened regulatory interest depending on how they are presented.
It is also important to understand the distinction between a dietary supplement and a conventional food. Supplements are products intended to supplement the diet and are consumed in discrete dosages such as capsules, tablets, or powders. Conventional foods are consumed primarily for taste, aroma, or nutritional value. A chocolate bar, even if fortified with melatonin or magnesium, will typically be considered a conventional food. This matters because certain ingredients may be lawful when used in dietary supplements but not approved for use in food products.
Ingredient-Specific Risks
Melatonin presents one of the most immediate risks in this space. Although widely used in dietary supplements for sleep support, melatonin has not been approved by FDA as a food additive. Its inclusion in chocolates, brownies, or similar products falls outside the current federal framework for lawful food ingredients. Some state attorneys general have raised alarms about melatonin in food-like formats, particularly where labeling does not clearly indicate dosage, safe use, or potential interactions. When such products are sold without age restrictions or resemble child-friendly treats, they can invite both regulatory scrutiny and consumer lawsuits.
L-theanine is generally considered safer from a regulatory standpoint, especially when derived from green tea and used at customary dietary levels. It is often self-affirmed as Generally Recognized as Safe (GRAS) and is commonly used in beverages and snacks targeting focus or calmness. Still, products making claims about stress reduction or mental clarity must have substantiation to support those benefits. The Federal Trade Commission (FTC) expects that such claims be supported by competent and reliable scientific evidence specific to the product or ingredient in its marketed context.
CBD continues to present a moving target for the food industry. Although many states have legalized the sale of CBD in food and beverage products, FDA maintains that CBD may not be legally added to conventional foods or marketed as a dietary supplement because it is an active drug ingredient. Despite this position, the agency has not issued formal rules, leading to inconsistent enforcement and a patchwork of state regulations. For brands using CBD in chocolates or other functional formats, the legal risk comes not only from the potential for FDA enforcement action, but also from potential class action lawsuits targeting label accuracy, dosage reliability, and implied health benefits.
Regulatory and Litigation Trends
FTC’s recent enforcement actions show that the agency is taking a close look at health claims related to mood, stress, and sleep. Under updated guidance issued in 2022, marketers must be able to demonstrate that any such claims are supported by solid scientific evidence that matches the formulation and dosage used in the product. This applies equally to supplements and conventional foods. Disclaimers such as “individual results may vary” or “not evaluated by FDA” do not insulate companies from scrutiny if their claims overpromise results or suggest treatment of a condition.
Class action litigation trends reinforce the need for caution. Functional food brands promoting stress or sleep benefits have increasingly been named in lawsuits alleging deceptive advertising, misbranding, or misrepresentation of ingredient efficacy. Plaintiffs often focus on claims like “clinically proven,” “drug-free sleep support,” or “relieves stress naturally,” arguing that such statements imply a level of scientific backing or therapeutic outcome that does not exist. Because these cases are often filed under consumer protection statutes, the legal exposure can be substantial even if the product causes no harm.
Mitigating Risk in the Functional Chocolate Space
To mitigate these risks, brands in the functional chocolate space should consider avoiding claims that suggest treatment, cure, or prevention of disease. Understanding whether a product can qualify as a supplement is equally important, particularly when using ingredients like melatonin or CBD. Proper scientific substantiation is not just a best practice; it is a legal requirement for marketing claims related to health. And because FDA, FTC, and state regulators each view labeling and marketing holistically, legal review of packaging, websites, and promotional materials should occur before the product launches.
