Dietary supplements are regulated by the FDA as food, not as drugs. Manufacturers are not required to confirm the identity of all ingredients supplied to them, and they are not authorized to approve dietary supplements for safety and effectiveness before they are marketed. The FDA's regulations require supplement manufacturers to follow good manufacturing practices to ensure the identity, purity, quality, strength, and composition of dietary supplements. However, supplements do not need to be evaluated for efficacy, and only limited data on safety are required for new supplement ingredients. This has resulted in several supplements containing contaminants, such as lead, arsenic, mercury, cadmium, or pesticides.

Dietary supplements are regulated as food, not drugs
Dietary supplements are not regulated as drugs by the FDA. The Dietary Supplement Health and Education Act (DSHEA) of 1994 amended the Federal Food, Drug, and Cosmetic Act, transforming the FDA's authority to regulate dietary supplements.
Under DSHEA, the FDA does not have the authority to approve dietary supplements for safety and effectiveness before they are marketed. Manufacturers are not required to confirm the identity of all ingredients supplied to them, and they may choose whether to be compliant with national standards set by the US Pharmacopoeia and National Formulary. Only six brands of dietary supplements are currently verified by the US Pharmacopoeia. This means that supplements can be marketed at any concentration, as long as the daily recommended value is specified on the label. If the daily recommended value is undetermined, supplements may be marketed without this information.
The FDA does, however, regulate dietary supplements as food. Manufacturers of dietary supplements must follow current good manufacturing practices (cGMP) to ensure the identity, purity, quality, strength, and composition of their products. They are also responsible for ensuring that their products are not adulterated, misbranded, or in violation of federal law. Labels on dietary supplements must include the product name, statement that it is a "dietary supplement", the name and place of business of the manufacturer, nutrition labeling, a list of "other ingredients", and the net quantity of contents.
Despite these regulations, a 2010 US Government Accountability Office report revealed that an analysis of 40 dietary supplements found trace amounts of lead, arsenic, mercury, cadmium, or pesticides in 93% of them. In 2011, 73% of supplement manufacturers inspected by the FDA failed to adhere to at least one regulation. This poor compliance has been attributed to inadequate enforcement by the FDA.
The FDA advises consumers to be informed about dietary supplements and to talk to their doctor, pharmacist, or other healthcare professionals before use.

Manufacturers set their own standards, leading to inconsistencies
Dietary supplements are regulated by the FDA as food, not as drugs. The FDA does not have the authority to approve dietary supplements for safety and effectiveness before they are marketed. This means that manufacturers set their own standards, which can lead to inconsistencies in the composition, strength, and bioavailability of products. For instance, a 2010 US Government Accountability Office report revealed that an analysis of 40 dietary supplements found trace amounts of harmful substances such as lead, arsenic, mercury, cadmium, or pesticides in 93% of them.
Furthermore, manufacturers are not required to confirm the identity of all ingredients supplied to them, and they may choose whether or not to comply with national standards set by the US Pharmacopoeia and National Formulary. Only six brands of dietary supplements are currently verified by the US Pharmacopoeia. A study comparing vitamin D3 concentrations in different brands revealed deviations, with pill potency ranging from 9% to 146% of the stated concentration.
The FDA's regulations require supplement manufacturers to follow good manufacturing practices to ensure the identity, purity, quality, strength, and composition of their products. However, the FDA's ability to monitor adverse events associated with supplement use is limited. Manufacturers are not required to forward reports of adverse events made to other agencies, and there is no legal liability to report serious adverse events.
While the FDA advises consumers to be cautious and consult healthcare professionals before using dietary supplements, the ultimate responsibility for ensuring the safety and accuracy of claims made about dietary supplements lies with the firms that manufacture and distribute them.

Supplements don't require evaluation for efficacy or extensive safety data
Dietary supplements are regulated by the FDA as food, not as drugs. The FDA does not approve dietary supplements for safety and effectiveness before they are marketed. Manufacturers are not required to confirm the identity of all ingredients supplied to them, and they may choose whether to be compliant with national standards set by the US Pharmacopoeia and National Formulary.
Supplements do not require evaluation for efficacy, and only limited data on safety are required for new supplement ingredients. There are no laws or regulations that limit the serving size of a dietary supplement or the amount of a dietary ingredient that can be in a serving of a dietary supplement. This decision is made by the manufacturer and does not require FDA approval.
Firms can introduce dietary supplements to the market without notifying the FDA, and the FDA often does not know when new products come on the market. The FDA's ability to link supplement use to adverse outcomes is compromised because medical records or product samples are not required, and manufacturers are not required to forward reports of adverse effects made to other agencies.

The FDA often doesn't know when new supplement products are marketed
Dietary supplements are regulated by the FDA as food, not as drugs. However, many dietary supplements contain ingredients that have strong biological effects, which may conflict with medication or medical conditions. Products containing hidden drugs are also sometimes falsely marketed as dietary supplements, putting consumers at risk.
The FDA does not approve dietary supplements before they are marketed. This means that the FDA often does not know when new products come on the market. Manufacturers are not required to confirm the identity of all ingredients supplied to them, and they may choose whether to be compliant with national standards set by the US Pharmacopoeia and National Formulary. Only six brands of dietary supplements are currently verified by the US Pharmacopoeia.
Supplements do not need to be evaluated for efficacy, and only limited data on safety are required for new supplement ingredients. Manufacturers are responsible for meeting safety standards and labeling requirements, but there are no laws or regulations that limit the serving size of a dietary supplement or the amount of a dietary ingredient that can be in a serving. This decision is made by the manufacturer and does not require FDA approval.
The FDA's ability to link supplement use to adverse outcomes is compromised because medical records or product samples are not required, and manufacturers are not required to forward reports of adverse effects made to other agencies. The FDA works with the FTC to regulate dietary supplement claims, and the FTC reviews the truth and accuracy of claims made in dietary supplement advertising and marketing.

The FDA can't approve supplement labels or claims before use
Dietary supplements are regulated by the FDA as food, not as drugs. However, the FDA does not have the authority to approve dietary supplements before they are marketed and sold. This means that the FDA cannot approve supplement labels or claims before use.
The Dietary Supplement Health and Education Act (DSHEA) amended the Federal Food, Drug, and Cosmetic Act (FD&C Act) to create a new regulatory framework for dietary supplements. Under DSHEA, the FDA does not have the authority to approve dietary supplements for safety and effectiveness before they are marketed. In fact, in many cases, firms can lawfully introduce dietary supplements to the market without even notifying the FDA.
Manufacturers are not required to confirm the identity of all ingredients supplied to them, and following cGMP guidelines does not guarantee the absence of all contaminants. A 2010 US Government Accountability Office report revealed that an analysis of 40 dietary supplements found trace amounts of lead, arsenic, mercury, cadmium, or pesticides in 93% of them.
The FDA's regulations require those who manufacture, package, or hold dietary supplements to follow current good manufacturing practices that help ensure the identity, purity, quality, strength, and composition of dietary supplements. Under the FD&C Act, a firm is responsible for ensuring that the dietary supplements it manufactures or distributes are not adulterated, misbranded, or otherwise in violation of federal law. If a manufacturer or distributor makes a structure/function claim, they must have substantiation that the claim is truthful and not misleading.
The FDA advises consumers to be informed and talk to their doctor, pharmacist, or other healthcare professional before using any dietary supplement.
