Don’t get scammed by “all natural” claims

FDA warns consumers about the dangers hidden in “all natural” dietary supplements, as well as products marketed to treat or cure certain conditions.

Dietary supplements that claim to be “all natural” aren’t necessarily safe. The Food and Drug Administration (FDA) has issued 2 Consumer Updates warning consumers about “all natural” products for erectile dysfunction and imported dietary supplements.

According to FDA, supplements marketed as “all natural” sexual-enhancement products might be tainted with hidden drug ingredients. Some of these are the same active ingredients found in prescription drugs used to treat erectile dysfunction. Not only could you potentially be consuming multiple drug ingredients, you could be consuming them in amounts even greater than prescription doses. Either way, these types of products can put your health and career in danger. For more information, please read FDA’s Consumer Update on "'All Natural' Alternatives..."

Consumers should also beware of dietary supplements and nonprescription drugs marketed as “all natural” remedies for serious conditions such as cancer, HIV/AIDS, diabetes, or heart disease. “Natural” does not necessarily mean safe, and these products also can contain undisclosed chemicals or drug ingredients that can be harmful. FDA specifically warns consumers about imported products sold online or at flea markets, or swap meets. Please read FDA’s Consumer Update on "Some Imported Dietary Supplements..." to learn more.

Decoding the dietary supplement industry

Not all supplements are created equal. Check out this new video from OPSS to learn more about the supplement industry and choosing supplements wisely.

Dietary supplements aren’t approved or evaluated by the Food and Drug Administration before they are sold on the market. That means there is no way to know whether a product contains the exact ingredients listed on the label or any undisclosed ingredients unless it’s tested in a laboratory. In fact, some supplements have been found to contain dangerous ingredients and even ingredients not allowable in dietary supplements. So how do you know which supplements are safe to take? Watch this new video from Operation Supplement Safety about Decoding the Dietary Supplement Industry.

Kratom concerns

Kratom use is on the rise, but is it safe?

Kratom (Mitragyna speciosa korth) is marketed and regulated as a dietary supplement in the United States, yet this psychostimulant has numerous side effects. It’s a tropical tree in Malaysia and has been used as an herbal drug for years. However, in the United States, the Food and Drug Administration says it is not approved for use in dietary supplements.

Operation Supplement Safety (OPSS) has an FAQ on kratom, which includes pertinent information from the Drug Enforcement Administration. Also visit other OPSS FAQs on various dietary supplement ingredients.

Don’t let supplements send you to the ER

Some supplements can have serious adverse effects and lead you to seek medical help. But there are things you can do to stay safe and out of the emergency room.

It is estimated that more than 20,000 Americans go to an emergency room every year for reasons related to dietary supplements such as allergic reactions and adverse events, according to a government study. Adverse events can result from ingredients in dietary supplements themselves or from drug-supplement interactions and can have serious side effects. Among adults, common complaints include chest pain and increased heart rate and are often associated with weight-loss products, energy products, bodybuilding products, and sexual-enhancement products.

Before taking any dietary supplement, talk to your doctor and be an informed consumer. It can prevent a health scare and even could save your life! For more information, please visit Operation Supplement Safety (OPSS), including the OPSS High-Risk Supplement List. And for more information about this study, read this article from MedlinePlus.

Green coffee beans: What’s all the hype?

Green coffee beans are popular for weight loss, but don’t be fooled by all the hype surrounding this dietary supplement ingredient.

If you’re looking for ways to optimize your performance or perhaps drop some weight quickly, you may be tempted by the marketing hype and claims around green coffee beans, a dietary supplement ingredient often found in weight-loss products.

Green coffee beans are the raw, unroasted seeds or “beans” of the Coffea plant. They’re a source of caffeine, but they have become popular as a dietary supplement ingredient because they also contain a chemical called chlorogenic acid that supposedly offers some health benefits.

Some research suggests that chlorogenic acid might help with weight loss and prevent heart disease, diabetes, and high blood pressure. However, there’s limited evidence to support the use of dietary supplement products with green coffee beans for weight loss or other health conditions, so consumers should beware of health claims associated with this ingredient. In fact, the Federal Trade Commission (FTC) sued a company for using unsupported weight-loss claims and fake news websites to market their green coffee extract dietary supplement. Read more in FTC’s Press Release.

Energy drinks: different labels, same risks

Energy drinks are now being marketed as conventional foods, but there are still risks involved. Learn how to stay safe if you drink these beverages.

Most energy drinks are now labeled with Nutrition Facts instead of Supplement Facts, but that doesn’t automatically make them safe. The most popular energy drinks contain about 80–120 mg of caffeine per serving (8 oz.)—about the same amount of caffeine in an 8-ounce coffee. Caffeine isn’t necessarily a bad thing. When used appropriately, caffeine can boost mental and physical performance. But each energy drink can or bottle often contains more than one serving, making it easier to consume larger amounts of caffeine, especially if you drink more than one per day. Too much caffeine (>400 mg) can cause nervousness, shakiness, rapid heart rate, and trouble sleeping.

In addition to caffeine, energy drinks commonly contain amino acids, vitamins, and plant-based ingredients such as guarana (which also contains caffeine) and ginseng. Although these ingredients are generally safe, there still isn’t enough reliable information about their long-term safety or how combinations of these ingredients might interact in the body.

If you drink energy drinks, here are some things to keep in mind:

  • Be aware of how much caffeine (from all sources) is in each can or bottle, and limit the number you drink each day.
  • Avoid caffeinated foods, beverages, and medications while using energy drinks. You may be consuming more caffeine than you realize.
  • Don’t mistake energy drinks for sports drinks. Unlike energy drinks, sports drinks are designed to fuel and hydrate you during long workouts.
  • Don’t mix energy drinks with alcohol. Energy drinks can mask the feeling of intoxication but still leave you impaired.
  • Find other ways to energize yourself. It’s best to get the sleep your body needs, but you can try other ways to stay alert, such as exercising or listening to upbeat music.

Understanding drug-supplement interactions

Do you take dietary supplements and medications? Read about the risks in a new resource from the National Center for Complementary and Integrative Health.

Many people take dietary supplements and medications together as a part of their daily health regimen, but few are aware of the potential for harmful interactions between prescription drugs, over-the-counter drugs, and dietary supplements. To help you learn more about these types of interactions, the National Center for Complementary and Integrative Health (NCCIH) created an interactive web resource that includes information about how supplements can change the effectiveness of your medications and how to work with your healthcare provide to make sure you’re taking them together safely. And for more information, please read HPRC’s Supplements and medications­ – What’s the problem?

Can SARMs do you harm?

SARMs can be found in some dietary supplement products, but are they legal and will they cause a positive drug test?

SARMs, or “selective androgen receptor modulators,” are experimental drugs that are illegal for use in dietary supplement products, but they still can be found in stores and on the Internet. SARMs are most often found in products advertised to have effects similar to those of anabolic steroids.

Read the Operation Supplement Safety (OPSS) FAQ about SARMs to learn more, including the ingredient names used for SARMs that may appear on dietary supplement labels. And remember: FDA does not approve dietary supplements prior to marketing. For more information on FDA’s role with regard to dietary supplements, visit FDA Basics.

Cannabidiol in dietary supplements

FDA says that products with the ingredient cannabidiol can’t be marketed as dietary supplements.

Cannabidiol (CBD) is a major chemical found in marijuana that may have beneficial effects on certain health conditions, but it’s still being tested as a new drug. However, FDA recently announced that products containing CBD cannot be sold as dietary supplements.
