Supplement 101
Supplement Is Not a Drug
Dietary supplements and drugs are regulated differently, with supplements positioned as food-like products that are not evaluated for effectiveness before market.
Supplements and drugs are defined by different standards.
They may look similar in form — capsules, tablets, powders —
but they are evaluated under fundamentally different regulatory frameworks.
The distinction is structural.
At a high level, the difference comes down to three signals:
- Intended use — drugs are intended to diagnose, treat, or prevent disease; supplements are intended to support the diet
- Pre-market evaluation — drugs require approval based on evidence of safety and effectiveness; supplements generally do not
- Regulatory burden — drug development involves controlled trials and formal review; supplements are governed by manufacturing and labeling rules
This creates two very different systems.
Drugs are evaluated before they are sold.
Supplements are monitored after they are sold.

A dietary supplement is a product intended to add nutrients or compounds to the diet, typically in forms such as capsules, tablets, powders, or liquids.
The FDA (U.S. Food and Drug Administration) is the primary federal agency responsible for regulating the safety, labeling, and manufacturing of food, drugs, and dietary supplements in the United States.
FDA recalls and safety alerts are post-market actions used to address unsafe or mislabeled supplements after they have entered the market.
