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.

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?
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 (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.

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.
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.
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.

Dietary supplements and medications (prescription or over-the-counter) can be a dangerous combination. Many dietary supplement ingredients, especially herbs and botanicals, can interact with drugs or even other dietary supplements, which can either increase or decrease the effectiveness of your medications. In other words, you could be getting too much or too little of the medications that you need, putting your health at risk.
If you are taking or plan on taking a dietary supplement, inform your healthcare provider to make sure it’s safe to use with your medications. Even then, you should still take caution, as some dietary supplements contain ingredients not listed on the label.
The Food and Drug Administration (FDA) advises consumers to be aware of certain supplement/drug interactions and offers tips to stay safe. For more information, see the FDA’s Consumer Update. And for information about many known interactions, visit the Natural Medicines Comprehensive Database (NMCD).
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.
