Congressman Langworthy Introduces Dietary Supplement Regulatory Uniformity Act

Rep. Nick Langworthy (R-NY) has introduced the Dietary Supplement Regulatory Uniformity Act, legislation intended to reaffirm a single federal standard for dietary supplement regulation under the U.S. Food and Drug Administration (FDA).

The proposal comes amid increasing state-level activity — particularly in New York — where additional requirements have been imposed beyond existing federal rules. Supporters of the bill argue that this has created inconsistent standards across states, adding compliance complexity for manufacturers and retailers.

What the bill proposes

Based on the press release, the legislation would:

• Clarify that FDA retains primary authority over dietary supplement regulation under federal law.

• Limit states from imposing additional, conflicting requirements beyond FDA standards.

• Preserve a mechanism for states to petition FDA when they believe a legitimate, evidence-based public health concern exists.

The intent, according to the bill’s sponsors, is to create greater regulatory consistency for products such as vitamins, protein powders, and other nutritional supplements that are already regulated by FDA under the Dietary Supplement Health and Education Act (DSHEA).

Why this is emerging now

State activity in recent years — especially in New York — has raised questions about the balance between federal and state authority in dietary supplement oversight. The bill reflects a broader debate over whether federal preemption should be strengthened to avoid a patchwork of requirements.

Industry trade associations including CHPA, CRN, NPA, and AHPA have publicly expressed support for the proposal, citing concerns about market fragmentation and compliance costs.

What this means for industry

If enacted, the bill could reduce variability in state requirements and reinforce reliance on FDA as the primary regulator of dietary supplements. However, the legislation would still need to move through committee review and broader Congressional consideration before becoming law.

EAS will monitor the progress of this bill and provide updates as additional details or amendments emerge.
