The Unregulated Meaning of "Natural"
Unlike the term "organic," which is highly regulated by the USDA for agricultural products, there is no official, legally enforced definition of "natural" for dietary supplements from the FDA. This absence of a clear standard means manufacturers have significant leeway in how they apply the term to their products. For many companies, "natural" simply means that the ingredients were derived from a natural source, such as a plant, mineral, or animal, rather than being synthetically created.
However, this definition leaves a great deal of room for interpretation regarding how these ingredients are processed. A supplement can be made from a naturally occurring herb, but the final product may still contain synthetic additives, preservatives, or colorings. The 'natural' label offers no guarantee about the product's safety, consistency, or purity, which can be misleading for consumers who assume it means safer or healthier.
What "Natural" Doesn't Guarantee
The lack of a strict definition means that a "natural" label on herbal and dietary supplements does not guarantee a number of things that consumers might assume:
- Absence of Synthetics: It doesn't guarantee the product is free from all synthetic substances, as some processing aids or flavorings may still be present.
- Minimal Processing: It doesn't mean the ingredients have undergone only minimal processing. Extraction, purification, and other manufacturing methods can be quite extensive.
- Enhanced Safety: The claim does not imply that the product is inherently safer than a non-natural alternative. Many natural substances can be toxic or have adverse side effects if taken incorrectly.
- Proven Efficacy: It provides no assurance of the supplement's effectiveness for a particular health condition. Claims of efficacy are regulated separately, and a "natural" product doesn't bypass these requirements.
Herbal vs. Dietary Supplements: A Key Distinction
Understanding the difference between these two terms is critical for comprehending the implications of a "natural" label. An herbal supplement is a type of dietary supplement, but not all dietary supplements are herbal.
- Dietary Supplements: These are products that contain one or more dietary ingredients, including vitamins, minerals, amino acids, botanicals (herbs), and more. They are intended to supplement the diet and are not regulated with the same scrutiny as pharmaceutical drugs.
- Herbal Supplements: These are dietary supplements that contain one or more herbs or botanicals. They can include whole plants or specific plant parts.
The "natural" claim can apply to both, but its meaning is equally undefined in either context. Whether a product is a vitamin, mineral, or herb, the label simply refers to the origin of the base ingredient, not the overall composition or manufacturing process.
Why You Should Be Skeptical of “Natural” Claims
Consumers are often drawn to the word "natural" believing it signifies a healthier or purer product. This can lead to dangerous assumptions, such as thinking that higher doses are safe or that a supplement is harmless to combine with other medications. The real information consumers need is available on the "Supplement Facts" label, not from the unregulated marketing terms.
For example, while St. John's wort is an herbal supplement used for depression, it can dangerously interact with many prescription medications, including antidepressants and birth control. The fact that it is a "natural" herb does not negate these powerful pharmacological effects. Similarly, many herbal supplements, such as kava and black cohosh, can cause liver damage. Relying on the "natural" label instead of a healthcare provider's advice is a risky proposition.
Natural vs. Organic vs. Regulated Medicine
To better understand what a "natural" supplement is, it helps to compare it to products that have stricter labeling rules.
| Feature | 'Natural' Supplements | 'Organic' Foods | Regulated Medicine |
|---|---|---|---|
| FDA Definition | No official, legal definition. | Highly regulated by USDA (for foods). | Approved for safety and effectiveness. |
| Manufacturing Oversight | Requires compliance with Good Manufacturing Practices (GMPs), but does not guarantee product consistency. | Certified agricultural production process overseen by USDA. | Extensive testing and FDA approval before sale. |
| Ingredient Sourcing | Generally implies derivation from natural sources, but can include synthetic additives. | Prohibits certain pesticides, fertilizers, and excluded methods like genetic engineering. | Ingredients are purified and strictly regulated for consistency and potency. |
| Safety Guarantees | No inherent safety guarantee; some natural substances can be harmful. | No inherent safety or health benefit guarantee, only production standard. | Tested for safety, side effects, and potential interactions before market. |
The Role of the Manufacturer
Under the Dietary Supplement Health and Education Act (DSHEA) of 1994, the responsibility for ensuring the safety and truthful labeling of a supplement falls primarily on the manufacturer, not the FDA. This places a great deal of trust in the company's integrity and quality control measures. Manufacturers must follow certain Good Manufacturing Practices (GMPs), but these do not extend to a definition of what constitutes "natural".
For the consumer, this means looking beyond marketing claims. Verifying third-party certification seals, such as those from USP (U.S. Pharmacopeia), ConsumerLab.com, or NSF International, can offer a higher level of assurance regarding a product's contents and quality. These independent organizations test supplements to verify they contain the ingredients listed on the label in the stated amounts and are free from contaminants.
How to Make Informed Decisions
Choosing a supplement requires diligence. Start by consulting a healthcare professional to discuss your health needs and potential interactions with other medications. When evaluating a product, ignore marketing fluff like the word "natural." Instead, focus on the following steps:
- Read the Supplement Facts Label: This is where you will find the actual ingredients and their quantities.
- Look for Third-Party Seals: Certifications from USP, ConsumerLab.com, or NSF International indicate that an independent organization has verified the product's quality and contents.
- Research the Ingredients: Don't just trust the label. Investigate the specific ingredients to understand their effects, potential side effects, and known interactions.
- Understand the Source: A natural source doesn't mean a pure or safe product. A natural extract from a plant could still be heavily processed and combined with synthetic fillers.
Conclusion
In conclusion, the term "natural" on herbal and dietary supplement labels is a marketing tool, not a regulated guarantee of quality, purity, or safety. The absence of a formal FDA definition allows manufacturers to use the term broadly, which can be misleading for consumers. For truly informed decisions, buyers must look past the buzzword and focus on the scientifically verified information found on the Supplement Facts panel and, ideally, confirmed by third-party testing organizations. Consulting a healthcare provider and conducting independent research are essential steps to ensure that any supplement taken is both safe and appropriate for one's health needs.
