DSHEA explained: how dietary supplements are regulated in the US

In the United States, no government agency approves a dietary supplement before it goes on sale. That single fact surprises people — and it is the direct result of the law that defines the entire US supplement industry: DSHEA. Understanding what DSHEA does, and does not, do is the foundation for everything else about selling supplements in America.

What DSHEA is

The Dietary Supplement Health and Education Act of 1994 (DSHEA) amended the Federal Food, Drug, and Cosmetic Act to create a distinct regulatory category for dietary supplements. It defined what a dietary supplement is, set the ground rules for how they are regulated, and placed them under the oversight of the FDA — but on very different terms from drugs.

No pre-market approval

The defining feature of the US system is that the FDA does not approve supplements before they are marketed. Unlike a drug, a supplement does not go through an approval process to demonstrate safety and efficacy before launch. A manufacturer can bring a product to market without prior FDA sign-off.

This is the opposite of pre-market regimes like Canada's or Australia's. In the US, the responsibility to ensure a product is safe and properly labeled sits with the manufacturer, not with a gatekeeping approval.

Responsibility shifts to the manufacturer

Because there is no approval step, the burden of compliance falls squarely on the company. The manufacturer is responsible for ensuring its products are safe, that any claims are truthful and not misleading, and that the product is produced and labeled according to the rules. The FDA's role is largely post-market — it acts against products that are unsafe, adulterated, or misbranded after they are on sale.

In practice, this means the discipline a US manufacturer applies to its own formulation, documentation, and labeling is the compliance system. There is no external approval to catch mistakes.

What the FDA still controls

No pre-approval does not mean no rules. The FDA enforces requirements on manufacturing practices, on labeling, on permitted claims, and on ingredient safety. A supplement still has to be produced under good manufacturing practice, labeled with a compliant Supplement Facts panel, make only allowed claims, and contain only ingredients that are lawful for use in supplements.

The agency can take action against products and companies that fall short — and it does. The freedom from pre-approval comes paired with real post-market accountability.

The new dietary ingredient exception

There is one notable place where something like a pre-market step exists. For a new dietary ingredient — broadly, one not marketed in the US before a defined point — a manufacturer may be required to notify the FDA with safety information before marketing. It is not an approval, but it is a pre-market notification obligation that sits within the otherwise post-market system.

A framework under review

DSHEA was written in 1994, and the supplement world has changed enormously since — new ingredient types, new production methods, a far larger market. The framework is the subject of ongoing discussion about modernisation, including how new ingredients are handled and how products are listed. Manufacturers should expect the details to keep evolving even as the core structure holds.

Because US supplement policy is actively being reviewed, confirm current FDA requirements for your specific products rather than relying on a general summary.

What it means for how you operate

The practical implication of DSHEA is that a US supplement company is its own first line of compliance. With no approval to lean on, the quality of your formulation control, your documentation, and your labeling is what keeps you on the right side of the law. The manufacturers who treat that internal rigour seriously are the ones who avoid post-market trouble.

The takeaway

DSHEA created a US supplement system with no pre-market approval, placing the responsibility for safety, claims, and labeling on the manufacturer, with the FDA acting after the fact. That freedom is real, but so is the accountability. Strong internal control over formulation, compliance, and documentation is not optional in this model — it is the system.

Lemoniq gives US manufacturers that internal control — one source of truth for formulation, compliance checks, and documentation — so the responsibility DSHEA places on you is something you can actually manage. We solve this exact problem. See how it works
