What Is GRAS?

A designation meaning a substance is generally recognised by qualified experts as safe for its intended use in food or supplements, based on a history of common use or adequate scientific evidence.

Why It Matters for Supplement Brands

Ingredients with GRAS status have a well-established safety profile, which can simplify regulatory pathways. However, GRAS status relates to safety — not efficacy. A GRAS ingredient still requires separate substantiation for any health-related claims made on the label.

How It Works

There are two GRAS pathways:

1. **Self-affirmed GRAS**: The manufacturer or ingredient supplier conducts (or commissions) a safety review and determines the substance is GRAS. This does not require FDA notification but does require maintaining records.

2. **FDA GRAS Notification**: A voluntary process where the company submits a GRAS notice to FDA, which then reviews and issues a 'no questions' letter. This provides a stronger regulatory position.

GRAS evaluations consider the cumulative dietary exposure, not just the amount in a single serving, and must be based on publicly available data.

Common Mistakes to Avoid

  • Assuming GRAS status means FDA has approved the ingredient (GRAS is a self-determination or voluntary notification)
  • Confusing GRAS (safety designation) with claim substantiation (efficacy evidence)
  • Relying on self-affirmed GRAS without conducting a proper expert panel review
