The global dietary supplement market was valued at approximately $192.68 billion in 2024 and is projected to reach $210.41 billion in 2025, according to Towards FnB, expanding at a compound annual growth rate (CAGR) of 9.2 percent. The United States (U.S.) accounts for a dominant share of global supplement revenues, with North America representing roughly 36 percent of global sales. Tennessee retailers selling vitamins and supplements are required to register their businesses through the Tennessee Taxpayer Access Point (TNTAP) at tntap.tn.gov, paying a $15 registration fee to the county or city clerk. All qualifying retail sales are subject to Tennessee’s 7% state sales tax. These regulatory and market forces shape how supplement businesses operate across the state.
The state’s consumer market operates within and contributes to these larger national trends. Tennessee’s health and wellness culture has expanded considerably over the past decade. Nashville’s emergence as a major healthcare hub, home to dozens of publicly traded healthcare companies, has attracted nutritional supplement brands and retailers seeking proximity to health-conscious consumers and medical innovation. Knoxville and Chattanooga have also developed robust wellness communities anchored by university health programs, fitness-oriented neighborhoods, and independent natural food retailers. Several direct-to-consumer supplement brands operate out of Tennessee, shipping products nationwide through e-commerce channels. This combination of strong local demand and a favorable business environment makes Tennessee one of the more active supplement markets in the South.
Tennessee market participants also face a body of federal regulations governing this product category. Federal oversight of dietary supplements falls primarily under the Food and Drug Administration (FDA), which regulates supplements as a distinct category of food under the Dietary Supplement Health and Education Act (DSHEA) of 1994. Unlike prescription drugs, supplements do not require premarket approval; however, manufacturers must comply with current good manufacturing practice (GMP) standards codified in 21 Code of Federal Regulations (CFR), Part 111, which covers manufacturing, packaging, labeling, and holding operations. Companies introducing ingredients not marketed in the U.S. before October 15, 1994, must submit a new dietary ingredient (NDI) notification to the FDA at least 75 days before marketing. The Federal Trade Commission (FTC) enforces Section 5 of the FTC Act, prohibiting unfair or deceptive advertising practices, including unsubstantiated health claims. Under 21 CFR Part 111, manufacturers are required to establish written product specifications for identity, purity, strength, and composition of every finished dietary supplement.
These regulatory standards create the backdrop for informed and practical purchasing decisions. Third-party testing seals, transparent ingredient labeling, and a healthcare provider’s guidance on potential drug interactions are the safeguards that protect Tennessee supplement buyers from misleading products. Independent third-party certifications from NSF International, the United States Pharmacopeia (USP), or Informed Sport verify that a supplement contains what its label claims and is free from banned substances or harmful contaminants. Reading supplement labels carefully reveals important distinctions: structure/function claims (e.g., “supports immune health”) are permitted under DSHEA but must be accompanied by a disclaimer that the statement has not been evaluated by the FDA. Claims that a product can treat, cure, or prevent a disease are prohibited for supplement products. Tennessee consumers also enjoy protections under the Tennessee Consumer Protection Act, Tennessee Code Annotated (TCA) § 47-18-104, which prohibits unfair or deceptive acts or practices in trade and commerce, including misleading labeling and advertising by retailers operating in the state. Healthcare providers can evaluate potential drug interactions before a new supplement enters a patient’s routine, and third-party testing seals from USP, NSF International, or ConsumerLab.com on the label indicate independent verification of product quality and ingredient accuracy.

Frequently Asked Questions
Do Tennessee supplement retailers need a business license?
Yes. All supplement retailers operating in Tennessee must obtain a business license by paying a $15 fee to the county or city clerk and registering through the Tennessee Taxpayer Access Point at tntap.tn.gov.
Is sales tax charged on vitamins and supplements in Tennessee?
Yes. Vitamins and dietary supplements sold at retail are subject to Tennessee’s 7% state sales tax, plus any applicable local option taxes. Unlike some prescription medications, over-the-counter supplements are not exempt from sales tax under current Tennessee law. For a full breakdown of taxable and exempt items, consult the Tennessee Department of Revenue at revenue.support.tn.gov.
What federal law governs dietary supplement safety and labeling?
The primary federal law is the Dietary Supplement Health and Education Act of 1994 (DSHEA), which defines dietary supplements and establishes the regulatory framework administered by the Food and Drug Administration. Manufacturers bear responsibility for ensuring their products are safe before marketing. See TCA § 47-18-104 for Tennessee’s consumer protection overlay.
Can supplement companies make disease claims on their products?
No. Under DSHEA and FDA regulations, dietary supplement manufacturers and retailers may not claim that a product diagnoses, treats, cures, or prevents any disease. Structure/function claims are permitted but must include a disclaimer that the statement has not been evaluated by the FDA. Complaints about deceptive supplement claims can be reported to the Federal Trade Commission at (877) 382-4357.
What are good manufacturing practice (GMP) requirements for supplements?
GMP requirements for dietary supplements are codified in 21 CFR Part 111, which requires manufacturers to establish written procedures, maintain batch records, conduct quality control testing, and verify product identity, purity, strength, and composition. Compliance is enforced through FDA facility inspections. For detailed regulatory text, see 21 CFR § 111.
How can Tennessee consumers verify supplement quality before purchasing?
Consumers should look for third-party certification marks from organizations such as NSF International, the United States Pharmacopeia, or Informed Sport, which verify label accuracy and screen for contaminants. Consumers can also search for FDA warning letters and recall notices before purchasing. Independent verification is provided by NSF International (nsf.org).
What return policies apply to vitamins and supplements purchased in Tennessee?
Unopened vitamins and supplements in their original factory-sealed containers are generally returnable within 30 days at Tennessee retailers with a receipt. Opened bottles of vitamins and supplements are non-returnable at most retailers due to safety concerns, as the product’s potency and integrity cannot be verified once the seal is broken. Prescription dietary supplements dispensed through a healthcare provider may have separate return policies. Manufacturer warranties do not apply to vitamins as consumable products, but many supplement brands offer satisfaction guarantees that provide a refund within 30 to 90 days of purchase if the buyer contacts customer service with proof of purchase. Tennessee buyers should verify that supplements carry a USP Verified, NSF Certified, or ConsumerLab-approved seal to ensure third-party quality testing. Products found to be mislabeled or adulterated may be reported to the FDA’s MedWatch program at (800) 332-1088 and the Tennessee Department of Agriculture.
