Health and wellness products are a broad category of consumer goods designed to support physical, mental, or emotional well-being without treating or curing a specific disease. They span everything from vitamin supplements and probiotic drinks to skincare serums, fitness trackers, and meditation apps. What ties them together is their intended purpose: maintaining or encouraging a healthy lifestyle rather than functioning as medicine. That distinction matters because it determines how these products are regulated and what companies can legally claim about them.
How These Products Are Defined
The FDA draws a clear line between wellness products and medical products. Under federal law, software or devices intended “for maintaining or encouraging a healthy lifestyle” that are “unrelated to the diagnosis, cure, mitigation, prevention, or treatment of a disease or condition” fall outside the definition of a medical device. This same logic applies across the wellness landscape. A fitness tracker that counts your steps is a wellness product. A wearable that claims to detect irregular heart rhythms is a medical device and must meet stricter regulatory standards.
This distinction creates a massive gray area that companies regularly exploit. A supplement can say it “supports immune health” but cannot say it “prevents colds.” A meditation app can offer relaxation exercises but cannot market itself as a treatment for clinical depression. The intended use, specifically how the product is positioned and marketed, is what determines which set of rules applies.
Dietary Supplements
Supplements are the largest and most familiar segment of health and wellness products. This includes vitamins, minerals, herbal extracts, amino acids, probiotics, and protein powders. In the United States, they’re regulated under the Dietary Supplement Health and Education Act of 1994, which places the burden of safety and labeling accuracy on the manufacturer, not the FDA. Companies must ensure their products aren’t adulterated or mislabeled before selling them, but they don’t need to prove a product actually works before it hits store shelves.
This system has real consequences for quality. A study of 634 non-hormonal supplements purchased across 13 countries found that 15% contained anabolic steroids not listed on the label. A later review of sports nutrition supplements found contamination rates between 12% and 58%. These aren’t fringe products from obscure websites. They’re supplements sold through normal retail channels. If you take supplements, choosing brands that voluntarily submit to third-party testing (look for USP, NSF, or Informed Sport seals) significantly reduces your risk of getting something you didn’t sign up for.
Skincare and Personal Care
The beauty and personal care industry increasingly markets products using wellness language: “clean,” “natural,” “science-backed.” Many of these products sit in a category informally called cosmeceuticals, meaning they contain biologically active ingredients but are sold as cosmetics rather than drugs.
Some of these ingredients have genuine evidence behind them. Niacinamide at concentrations of 2% to 5% reduces inflammation, tightens pores, and improves the skin’s protective barrier with relatively few side effects. Retinol, a vitamin A derivative, is one of the most studied anti-aging ingredients available, but it needs to be present at a minimum concentration of 0.025% to have any effect. Many over-the-counter products contain less than that, making them essentially inactive. Dryness and irritation increase with higher concentrations, so effective retinol products require a real tradeoff.
The challenge for consumers is that cosmetic products don’t require the same clinical proof as drugs. A moisturizer can contain a trace amount of an active ingredient and market itself using the research done on that ingredient at much higher doses. Reading ingredient lists and understanding effective concentrations gives you a significant advantage.
Functional Foods and Beverages
Functional foods are everyday foods or drinks enhanced with additional ingredients intended to provide a health benefit beyond basic nutrition. The category includes probiotic yogurt drinks, calcium-fortified milk, omega-3-enriched juices, vitamin-infused waters, sports drinks, and herbal beverages. The concept is simple: take something people already eat or drink and add something beneficial to it.
Probiotics are one of the better-supported functional ingredients. These are live microorganisms that, when consumed in adequate amounts, can benefit digestive health. Probiotic yogurts and fermented drinks have decades of research behind them. Prebiotics, which are fibers that feed beneficial gut bacteria, are another well-studied category. Both have been shown to support regular digestive function.
Other functional beverages make vaguer promises. Products marketed with terms like “wellness blend” or “superfood infusion” often contain ingredients in amounts too small to produce measurable effects. The same principle from skincare applies here: the presence of an ingredient on a label tells you nothing about whether it’s present in a meaningful dose.
Digital Wellness Tools
Apps and wearable devices now represent a fast-growing slice of the wellness market. This includes meditation and mindfulness apps, sleep trackers, mood journals, breathing exercise tools, and fitness platforms. The regulatory picture depends entirely on what the product claims to do.
A mindfulness app that guides you through relaxation exercises is a general wellness tool and typically faces no FDA oversight. An app that delivers cognitive behavioral therapy for anxiety or tailors interventions for depression based on reported symptom severity is classified as Software as a Medical Device and must meet regulatory standards for safety and effectiveness. The FDA evaluates these products based on their intended use and how they position themselves in the marketplace.
This creates a practical problem. Without regulatory oversight, wellness apps can imply therapeutic benefits without substantiating them. An app might use clinical-sounding language and present mood tracking features in ways that suggest it’s treating depression, while technically stopping short of making a direct treatment claim. If you’re using a digital tool for a specific mental health concern, checking whether it has FDA clearance or is backed by published clinical trials is worth the extra few minutes of research.
How Advertising Claims Are Regulated
The Federal Trade Commission requires that any claim about the health benefits or safety of foods, supplements, drugs, or other health-related products be backed by “competent and reliable scientific evidence.” In practice, this means randomized, controlled human clinical trials. The FTC evaluates several factors when deciding how much evidence is enough: the type of product, the type of claim, how easily the consumer could verify the claim on their own, and the potential consequences if the claim turns out to be false.
Claims that are hard for consumers to evaluate independently are held to a stricter standard. If a product says it reduces joint pain, for example, that’s a subjective experience influenced by placebo effects and natural symptom fluctuation. The FTC expects stronger evidence for that kind of claim than it would for something a consumer can directly observe. Products related to health or safety generally require the highest level of scientific support.
Despite these rules, enforcement is reactive rather than preventive. The FTC pursues companies after products are already on the market, often after consumers have spent years buying them. The practical takeaway: a product being sold legally doesn’t mean its claims have been verified. It means no one has successfully challenged them yet.
How to Evaluate Products
The wellness market is enormous, and most of it operates in a regulatory space that rewards marketing over evidence. A few principles help you navigate it:
- Check the dose, not just the ingredient. Many products contain active ingredients at concentrations too low to produce any effect. If a company doesn’t disclose how much of a key ingredient is in the product, that’s usually a sign the amount is negligible.
- Look for third-party testing. For supplements, certifications from independent testing organizations confirm that what’s on the label is actually in the bottle, and that contaminants are absent.
- Be skeptical of vague claims. Phrases like “supports wellness,” “boosts vitality,” or “promotes balance” are deliberately chosen because they’re too vague to be challenged by regulators. Products with specific, evidence-backed claims tend to be more transparent about the science behind them.
- Distinguish wellness from treatment. If you’re managing a diagnosed health condition, products marketed as general wellness tools are not substitutes for evidence-based treatments, regardless of how scientific their branding looks.
