Understanding the Definition of a Dietary Supplement
To determine which of the following is not a dietary supplement, it's essential to understand the U.S. Food and Drug Administration's (FDA) definition, established by the Dietary Supplement Health and Education Act (DSHEA) of 1994. DSHEA defines a dietary supplement as a product taken by mouth that contains a "dietary ingredient" intended to supplement the diet, such as vitamins, minerals, herbs, amino acids, or enzymes. Supplements are categorized under "foods" rather than drugs.
This legal distinction means that conventional food items, like a steak dinner or pasta, are not dietary supplements. Supplements are concentrated nutrient sources, not meals.
Key Distinctions Between Conventional Food and Supplements
A major difference is the intended use and labeling. Conventional foods are for taste, aroma, or overall nutritional value as part of a meal. Supplements fill nutritional gaps or provide a concentrated dose of specific ingredients. Labels clearly show this difference.
The form of consumption is also a factor. Supplements are typically taken in controlled doses as capsules, tablets, powders, or liquids. Food is consumed as part of regular eating without a specific dose.
Common Examples of What Is and Is Not a Supplement
-
Foods that are NOT supplements:
- Fresh fruits and vegetables (e.g., an apple, a carrot)
- Conventional meals (e.g., a sandwich, a plate of chicken)
- Fortified foods like vitamin D-fortified milk, which are still consumed as food.
- Standard beverages for hydration or general consumption.
-
Products that ARE supplements:
- Vitamins and minerals: Calcium tablets, vitamin C capsules.
- Herbs and botanicals: Echinacea pills, turmeric capsules.
- Amino acids and proteins: Protein powder.
- Live microbials: Probiotic capsules.
- Specialty ingredients: Fish oil capsules, melatonin tablets.
The Role of Labeling and Regulation
A product's labeling is a key indicator of its classification. Dietary supplements must have a "Supplement Facts" panel listing ingredients and amounts. Conventional food has a "Nutrition Facts" panel. This labeling helps consumers understand the difference. Supplements are not FDA-approved like drugs; manufacturers are responsible for safety, with the FDA intervening only if a product is found unsafe.
Comparison Table: Dietary Supplement vs. Conventional Food
| Feature | Dietary Supplement | Conventional Food |
|---|---|---|
| Primary Purpose | To supplement the diet. | To provide primary nutrition and energy. |
| Form | Capsules, tablets, powders. | Solid or liquid meals. |
| Labeling | "Supplement Facts" panel. | "Nutrition Facts" panel. |
| Regulation | Regulated as food; no pre-market FDA approval. | Subject to food safety regulations. |
| Dosage | Specific, measured dose. | Consumed as part of a meal without a controlled dose. |
Conclusion: Making Informed Choices
The key to identifying which of the following is not a dietary supplement lies in its primary purpose and form. Conventional food provides foundational nutrition in a meal, while a supplement is a concentrated product enhancing the diet. Check the label for a "Supplement Facts" panel versus a "Nutrition Facts" panel. For health concerns or supplement needs, consult a healthcare professional.

No, a product cannot legally be both. It's either labeled as a supplement or not. Fortified foods are an exception; they are conventional foods despite added nutrients.
Are meal replacement shakes considered dietary supplements?
Generally, no, as they are marketed as meal substitutes, which contradicts the definition of a supplement.
Do dietary supplements need FDA approval before being sold?
No, the FDA does not approve dietary supplements for safety or effectiveness before sale. Manufacturers are responsible for safety.
What should I do if I suspect a supplement is unsafe?
Stop use, seek medical advice, and report the event to the FDA.
Can supplements treat or cure diseases?
No, supplements cannot legally claim to treat, diagnose, cure, or prevent any disease, as such claims are for drugs.
