Keto Supplements: Fda Approval And Safety Concerns

The popularity of keto diets has led to a booming market for keto supplements, but do these products work, and are they approved by the FDA? The short answer is no—dietary supplements, including keto products, are not approved by the FDA. The FDA does not approve dietary supplements for safety, effectiveness, or their labeling before they are sold to the public. Instead, supplement companies are responsible for ensuring their products are safe and accurately labeled. The FDA's role in regulating dietary supplements is largely reactive, beginning after products enter the market. While the FDA can take action to bring a product into compliance or remove it from the market, it does not approve supplements in the same way it regulates prescription medication.

The FDA does not approve dietary supplements

The FDA does regulate dietary supplements, but this regulation comes after products enter the marketplace. The FDA's authority in this area comes through the Dietary Supplement Health & Education Act (DSHEA), passed in 1994, which defines what dietary supplements are and includes guidance on how they should be sold and regulated. The FDA regulates dietary supplement marketing, ingredient safety, and manufacturing.

The FDA has established different sets of current Good Manufacturing Practices (cGMPs) for pharmaceutical products, medical devices, and foods (dietary supplements fall under "foods" in the FDA's classification scheme). While the FDA expects manufacturers of dietary supplements to comply with cGMPs, it does not certify manufacturers that are in compliance. Facilities are registered with the FDA, which conducts inspections and points out any deficiencies that need to be corrected.

The FDA also reviews and approves the introduction of new ingredients to the market by classifying ingredients as generally recognized as safe (GRAS) or as new dietary ingredients (NDI). If evidence indicates that an ingredient is harmful, the FDA mandates its removal from the marketplace.

It is important to note that products claiming to treat, diagnose, prevent, or cure diseases are generally subject to regulation as drugs.

Keto supplements may contain hidden gluten

The U.S. Food and Drug Administration (FDA) does not approve dietary supplements for safety, effectiveness, or their labeling before they are sold to the public. Dietary supplement companies are responsible for ensuring their products are safe and accurately labeled. The FDA does, however, regulate dietary supplements and their marketing, ingredient safety, and manufacturing.

In May 2022, the FDA announced that a major supplement maker, Natural Organics Inc., had voluntarily recalled its KetoLiving Sugar Control capsules. Tests revealed that these pills, which were labeled gluten-free, contained gluten, which can cause "serious or life-threatening" reactions in people with gluten intolerance.

Gluten is a combination of proteins found in wheat, barley, and rye. It causes damage to the small intestines of people with the autoimmune disorder celiac disease and other side effects in people with gluten allergies or sensitivities. While keto diets are gluten-free-friendly, and keto is a low-carb diet that naturally cuts out problematic foods for people with gluten intolerance, some keto supplements may contain hidden gluten.

"Hidden" gluten refers to gluten that is either not mentioned on a product label in an obvious way or is in products that do not seem likely to contain gluten but do. While FDA-compliant food labels specify "wheat" in the ingredients list or in a "Contains" statement for any ingredient derived from wheat, there are no required warnings for barley or rye as these grains are not considered major allergens by the FDA. The Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA) identified eight foods as major food allergens: milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soybeans.

Therefore, if you are gluten-sensitive, it is important to be vigilant about reading food labels to identify hidden gluten. Additionally, some packaged foods that are usually gluten-free may come in a specialty flavor or be made by a specialty product producer that could potentially contain gluten. Imported packaged foods could also contain gluten grain derivatives, even if similar products are considered gluten-free in the U.S.

The bottom line is that the FDA does not approve dietary supplements, including keto supplements, but it does regulate them. It is important for consumers to be aware that keto supplements may contain hidden gluten and to carefully check product labels and contact the manufacturer if needed to identify it.

Keto supplements are not proven to work

The U.S. Food and Drug Administration (FDA) does not approve dietary supplements, including keto products, for safety and effectiveness or their labelling before they are sold to the public. Instead, dietary supplement companies are responsible for ensuring their products are safe and accurately labelled.

The FDA does, however, regulate dietary supplements in several ways. Firstly, the FDA monitors marketing claims made by dietary supplement companies. There is a requirement in place that claims, generally referred to as "structure/function claims", must be submitted to the FDA within 30 days of a dietary supplement hitting the market. These claims must be substantiated by data, preferably from randomised controlled trials.

Secondly, if evidence indicates that an ingredient is harmful, the FDA mandates its removal from the marketplace. The FDA has also created an Ingredient Advisory List for ingredients that it is investigating further for safety.

Thirdly, the FDA reviews and approves the introduction of new ingredients to the market by classifying them as "generally recognised as safe" (GRAS) or as new dietary ingredients (NDI).

Fourthly, the FDA inspects manufacturing facilities to make sure they follow current Good Manufacturing Practices (cGMPs).

Despite this regulatory involvement, dietary supplements are not required by law to go through the same kind of testing as pharmaceutical products. Manufacturers of supplements do not have to show their products are safe or effective before selling them, unless they contain "novel" ingredients, which must be rigorously tested for safety.

Keto supplements typically contain two active ingredients: ketone beta-hydroxybutyrate (BHB), a compound that the liver produces from fats, and medium-chain triglycerides (MCTs), a type of fat found in coconut and palm oil that can be used as a source of energy for the body in ketosis.

There is not enough research on the efficacy of keto supplements to support the claim that taking keto pills, powders or gummies will help you achieve ketosis. One small 2021 study found that obese people who followed a low-calorie ketogenic diet and took 24 grams of a BHB salt supplement per day for six weeks experienced enhanced ketosis. However, having higher levels of ketones in the blood did not seem to boost weight loss when compared to other groups, such as those following only the keto diet without the supplement.

Other research, such as a 2020 study, suggests that taking exogenous ketones can help boost concentrations of ketones in the blood quickly. Whether they have an appreciable effect on weight loss, however, is still unclear, and more robust studies with strong evidence are lacking.

One reason why supplementation may not be very effective is that the body seeks to maintain an even level of ketones to prevent a potentially toxic buildup of these chemicals in the bloodstream. When the body senses that ketone levels are high, the liver stops making its own and will try to flush out excess ketones in your urine, a process called ketonuria.

Ultimately, the jury is still out on whether or not these supplements work. But one thing is for certain: experts do not recommend keto pills – or any diet pill, for that matter.

Dietary supplements are not required to be tested like pharmaceutical products

The FDA does set certain requirements for dietary supplements, such as current good manufacturing practices (GMP) outlined by the FDA. These practices include identity, strength, quality, purity, potency, and composition. However, it is the brand owner's responsibility to determine the appropriate, scientifically valid testing methods to verify these factors. The FDA does not approve or certify supplements before they are marketed and can only take regulatory action after a supplement is on the market.

The lack of pre-market testing for dietary supplements is often criticized as it leaves consumers potentially vulnerable to unsafe products. Post-market adverse event monitoring is the primary way to evaluate the quality, safety, and efficacy of dietary supplements. This monitoring includes consumer reports of health-related reactions or illnesses associated with the use of a dietary supplement.

While dietary supplements are not held to the same testing standards as pharmaceutical products, there are still some safety measures in place. For example, the FDA can work with companies to bring a product into compliance or remove it from the market if it is found to be unsafe. Additionally, the FDA reviews and approves the introduction of new ingredients by classifying them as generally recognized as safe (GRAS) or as new dietary ingredients (NDI).

In summary, while dietary supplements are regulated by the FDA, they are not required to undergo the same rigorous testing as pharmaceutical products. The responsibility for ensuring the safety and accuracy of dietary supplements falls primarily on the brand owners and manufacturers, with the FDA taking action as needed after the products enter the marketplace.

The FDA regulates dietary supplement marketing, ingredient safety, and manufacturing

The Food and Drug Administration (FDA) does regulate dietary supplements, but this does not equate to approval. The FDA's authority in this area comes from the Dietary Supplement Health and Education Act (DSHEA), passed in 1994. This act defines dietary supplements and provides guidance on their sale and regulation.

The FDA regulates dietary supplements in several ways. Firstly, it monitors marketing claims made by supplement companies. There are strict requirements for these claims, often referred to as "structure/function claims", which must be submitted to the FDA within 30 days of a supplement's release. These claims must be supported by data, preferably from randomized controlled trials. The FDA is vigilant in ensuring supplement companies do not claim their products prevent or cure diseases, as this would violate the rules and result in the product being viewed as an unregulated medicine.

Secondly, the FDA has the authority to mandate the removal of ingredients from the marketplace if evidence indicates they are harmful. The FDA also maintains an Ingredient Advisory List of substances under investigation for safety concerns. While inclusion on this list doesn't prove an ingredient is unsafe, manufacturers are less likely to include such ingredients in their products.

Thirdly, the FDA reviews and approves new ingredients introduced to the market, classifying them as either generally recognized as safe (GRAS) or as new dietary ingredients (NDI). Lastly, the FDA inspects manufacturing facilities to ensure compliance with current Good Manufacturing Practices (cGMPs). These practices cover various aspects, from raw material verification to finished product testing and accurate labelling.

While dietary supplements are regulated by the FDA, they are not subject to the same rigorous testing and approval process as pharmaceutical products. Supplement manufacturers are not required to prove their products' safety or effectiveness before selling them, unless they contain "novel" ingredients introduced after 1994. In this context, "novel" ingredients must be rigorously tested for safety and can be classified as GRAS.
