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.

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.

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.

Are supplements the “whey” to protein?

Whey protein is often referred to as the “king of proteins.” But are whey protein supplements the best option for muscle growth and recovery?

Whole foods, not dietary supplements, should be your first choice for protein. Protein supports muscle growth and repair. People often turn to protein supplements (such as whey, casein, and soy) to optimize those effects, especially after a workout. Whole food protein sources such as lean meats, fish, dairy products, legumes, nuts, and seeds are just as effective (in some cases more effective) than protein supplements. Whey protein products can be an acceptable, convenient, and efficient way to deliver protein when your needs are greater or when normal dietary sources are not available. If you are using protein supplements, be sure to choose a product that has been third-party evaluated for its quality. Read more here.

FDA warns again about powdered caffeine

FDA issued warning letters to 5 distributors of powdered pure caffeine and continues to warn consumers against using these products.

The Food and Drug Administration (FDA) is again warning about the dangers of powdered pure caffeine. At least 2 deaths (both teenagers) were associated with it in 2014, yet it continues to be sold, primarily in bulk online. FDA recently sent warning letters to 5 distributors of pure powdered caffeine, warning about potential serious health effects. FDA notes that it’s difficult to determine the difference between a safe amount and a toxic amount but that one teaspoon is roughly equivalent to 28 cups of coffee. For more information, read FDA’s update and HPRC’s 2014 article.

Protein powders: Food or supplements?

Some protein powders have Nutrition Facts labels while others have Supplement Facts labels. Is this a case of mislabeling?

Conventional foods and dietary supplements follow different rules when it comes to labeling, but the difference between the two isn’t always black and white. Such is the case with protein powders. If you look closely at various protein powders, you may notice that some are labeled with Nutrition Facts (required for foods), while others have Supplement Facts (required for supplements). So are protein powders conventional foods or dietary supplements? Read more in our OPSS FAQ on protein powder labels.

What’s in your energy drink?

Energy drinks are really “stimulant” drinks. Learn how to identify potentially harmful ingredients.

Stimulants can be dangerous to your health, especially in large quantities, but they’re what give energy drinks their “punch.” You may already know caffeine is a major stimulant found in energy drinks. But do you know that energy drinks often contain other stimulants? These can include “hidden sources” of caffeine (such as guarana, green coffee bean, green tea, and yerba mate), yohimbe, and synephrine (bitter orange).

Many energy drinks, however, aren’t labeled with the amounts of caffeine or other stimulants in them. Some or all of these ingredients are often part of “proprietary blends,” so it’s impossible to determine from the label the exact amount of each ingredient you would be taking. Furthermore, energy drinks might be mislabeled or marketed as sports drinks, causing even more confusion.

Remember, stimulants come in many different forms, so Operation Supplement Safety (OPSS) put together a list of stimulants found in dietary supplements to help you identify these potentially harmful ingredients. And to help you understand what’s in your energy drink, check out the OPSS infosheet on energy drink labels, which includes helpful notes about ingredients.
