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.

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.

Energy drinks and teens don’t mix

Energy drinks have become increasingly popular among teens, but they provide no health benefit and can even be harmful.

It’s cause for concern: Approximately 30% of teens consume energy drinks on a regular basis. Energy drinks provide no nutritional benefit and can actually pose health risks to adolescents, including increased heart rate, high blood pressure, anxiety, digestive problems, sleep disturbances, dehydration, and even death. Teens who consume energy drinks are also more likely to engage in unhealthy behaviors such as drinking more sugar-sweetened beverages, smoking cigarettes, and using drugs and alcohol.

Many of the negative effects associated with energy drinks are due to the large amounts of stimulants in these beverages. Their caffeine content can range from 50 to more than 500 mg per can or bottle. The American Academy of Pediatrics recommends that children and teens:

  • consume no more than 100 mg of caffeine per day (equal to about 2 cans of caffeine-containing soda or one 8 oz. cup of coffee) and
  • avoid energy drinks altogether.

However, the amount of caffeine teens consume from energy drinks is trending upwards, in part due to heavy marketing with celebrity athletes. Be sure to talk to your teens about the potential problems associated with energy drinks, and make sure they don’t confuse them with sports drinks.

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. 

What are high-risk supplements?

HPRC Fitness Arena: Dietary Supplements
Some dietary supplement products contain problematic ingredients. Find out which ones might pose a health risk.

High-risk dietary supplements are those that may present serious health risks. Many have been found to contain undeclared drug ingredients, steroids, steroid-like ingredients, and/or stimulants, which can have negative and dangerous side effects. Products most commonly “tainted” in this way are those marketed for bodybuilding, performance enhancement, weight loss, sexual enhancement, and diabetes. Such products may also result in a positive drug test. For more information, read FDA’s Consumer Update “Tainted Products Marketed as Dietary Supplements.” For more information about urinalysis and drug testing, read HPRC’sDietary supplements and drug testing."

In addition, you can visit the OPSS High-Risk Supplement List for information about certain dietary supplements that may pose a health or sport anti-doping risk.
