How the GRAS Process Works for New Food Ingredients

If you develop products in the food, beverage, or supplement space, you have probably encountered the term GRAS. It shows up in ingredient documentation, regulatory discussions, and safety evaluations, but many brands are not fully clear on what it actually means or how it works.

Understanding GRAS matters because it is one of the main ways companies demonstrate that an ingredient is safe for use in food products in the United States.

This article explains what GRAS means, how the GRAS process works, when brands should pursue GRAS status, and where clinical research can help support ingredient credibility.

What Does GRAS Mean?

GRAS stands for “Generally Recognized as Safe.” It is a regulatory designation used by the U.S. Food and Drug Administration (FDA) to indicate that a substance is considered safe for its intended use in food based on scientific evidence or a long history of safe consumption.

In practice, GRAS status allows companies to use certain ingredients in food products without requiring formal FDA premarket approval, as long as safety is supported by qualified scientific experts.

What Does GRAS Actually Allow a Company to Do?

In simple terms, GRAS status allows a company to use an ingredient in food products because its safety is widely accepted by qualified experts.

Instead of submitting a full food additive petition to the FDA, a company can demonstrate that the ingredient’s safety is already supported by:

• Published scientific research

• Toxicology and safety data

• Historical consumption data

• Expert panel evaluation

If the evidence supports safety, the ingredient can be considered GRAS for a specific use case, such as a certain dosage in beverages, bars, or functional foods.

It is important to understand that GRAS is not a blanket approval for any use of an ingredient. The safety conclusion must be tied to:

• The ingredient identity

• Intended use

• Maximum use levels

• Target population

How Does the GRAS Process Work?

The GRAS process typically involves a structured scientific review of an ingredient’s safety profile.

Step 1: Gather Scientific Evidence

Companies collect data that supports ingredient safety, including:

• Toxicology studies

• Human clinical studies

• Metabolism and absorption data

• Historical food consumption data

For newer functional ingredients, human clinical studies can play an important role in strengthening the safety narrative.

Step 2: Conduct an Expert Panel Review

A group of independent scientists evaluates the available data to determine whether the ingredient is generally recognized as safe among qualified experts.

The panel typically includes specialists in areas such as:

• Toxicology

• Food science

• Clinical research

• Regulatory science

If the panel agrees that the evidence supports safety, they may issue a GRAS conclusion.

Step 3: Optional FDA GRAS Notification

After the expert review, companies may choose to submit a GRAS Notification to the FDA.

The FDA then reviews the submission and typically responds with one of three outcomes:

• No questions regarding the GRAS conclusion

• Insufficient basis for the GRAS claim

• Cease to evaluate request

Many brands pursue FDA notification because it provides additional transparency and regulatory confidence.

GRAS vs Food Additive Approval

Brands often confuse GRAS status with formal food additive approval. The two pathways serve similar safety purposes but follow different regulatory processes.

Feature	GRAS	Food Additive Approval
FDA pre-approval required	No	Yes
Based on expert consensus	Yes	No
Common for widely studied ingredients	Yes	Less common
Regulatory pathway	GRAS notification	Food additive petition
Timeline	Often shorter	Typically longer

For many food and beverage companies, GRAS is the more practical pathway when sufficient safety evidence already exists.

When Should a Brand Pursue GRAS Status?

GRAS status is most useful when a company plans to introduce an ingredient into foods, beverages, or functional nutrition products.

Common scenarios include:

• Launching a new functional ingredient in beverages or snacks

• Introducing novel botanical extracts in food products

• Commercializing bioactive compounds for food use

• Expanding ingredient usage into new food categories

For example:

• A brand developing a nootropic beverage may pursue GRAS status for a cognitive ingredient used at 150 mg per serving.

• A protein ingredient used historically in powders may need GRAS evaluation before entering ready-to-drink beverages.

• A botanical extract standardized to 5 percent active compounds may require a safety review before inclusion in functional snacks.

When Should You Avoid Relying on GRAS Alone?

GRAS status focuses specifically on safety for food use, not product efficacy or marketing claims. Brands should avoid relying on GRAS when they need to demonstrate:

• Clinical benefits for marketing claims

• Consumer outcomes like energy, sleep, or immunity

• Differentiation in competitive supplement categories

In these situations, human clinical studies are often needed to support product positioning.

For example, GRAS may confirm that an ingredient is safe at 200 mg per day, but it does not prove that it improves cognitive performance or reduces fatigue.

That type of evidence typically comes from controlled human trials.

Where Clinical Research Fits Into Ingredient Credibility

While GRAS establishes safety, clinical research supports performance and consumer trust.

For many functional ingredients, brands pursue both:

1. GRAS safety evaluation for food use

2. Human clinical studies to support structure-function claims

For example:

• A hydration ingredient may undergo GRAS evaluation for beverage inclusion.

• A 12-week randomized clinical study with 80 participants could then measure hydration markers and consumer outcomes.

Companies often partner with clinical research organizations such as Citruslabs to design and run these human studies so brands can better understand how their ingredients perform in real-world use.

Common Mistakes Brands Make With GRAS

Assuming GRAS Means FDA Approval

GRAS is a scientific safety determination, not a formal FDA approval.

Treating GRAS as a Marketing Claim

GRAS supports regulatory safety, not product benefits.

Ignoring Use-Level Limits

GRAS conclusions apply only to specific use levels and product categories. Using an ingredient outside those parameters may require a new evaluation.

What Brands Should Know About GRAS

GRAS plays an important role in ensuring food ingredient safety, especially as functional foods and wellness products continue to grow.

Key takeaways:

• GRAS means “Generally Recognized as Safe” and indicates expert consensus on ingredient safety for a specific use.

• The GRAS process evaluates scientific evidence, safety data, and expert opinion.

• GRAS supports ingredient safety but does not replace clinical research for efficacy or product claims.
  

For brands developing innovative health and wellness products, combining strong safety evidence with human clinical data is often the most effective way to build credibility with regulators, retailers, and consumers.
