Pre-Workout Powder Recalled Due to Illegal Stimulant Linked to Heart Attacks

A pre-workout powder is being recalled due to the presence of an illegal stimulant that can lead to serious cardiovascular problems, including heart attacks. The U.S. Food and Drug Administration (FDA) found that RAPTURE Preworkout powder contained 1,3-dimethylamylamine (DMAA), an amphetamine derivative that can dangerously raise blood pressure.

Leader Formulas, a Texas-based sports supplement company, has issued a voluntary nationwide recall for one lot of the RAPTURE Preworkout powder. The affected lot number is 260327-4 and was distributed between January 29, 2025, and May 25, 2026. The product is packaged in round plastic containers with red and black lettering and a rhinoceros-printed seal, and comes in three flavors: Rainbow Twist (UPC 710154236506), Electric Lemonade (710143236513), and Berry Mojito (710154236544).

Consumers who have purchased the recalled product are advised to stop using it immediately and return it to the place of purchase for a full refund, according to the FDA.

Understanding DMAA

DMAA was previously used as a pharmaceutical medication for nasal decongestion but was removed from the market in the 1980s due to its side effects. The FDA stated that DMAA narrows blood vessels and arteries, which can lead to elevated blood pressure. This can result in cardiovascular issues such as shortness of breath, chest tightening, arrhythmias, and heart attack, as well as seizures and other neurological and psychological conditions.

Despite its history, DMAA reappeared on the market around 2006, marketed for weight loss and athletic performance enhancement. However, following further research, it was banned in several countries, including Canada in 2011 and the United States in 2012 and 2013.

The FDA has expressed significant concern regarding DMAA and advises consumers against purchasing or using any product containing it, classifying it as an unsafe food additive. While the company has not reported any adverse events linked to this recall, the FDA is taking swift action.

There are claims that DMAA is a natural stimulant derived from plants, but the FDA maintains there is no reliable scientific evidence to support this. Pre-workout supplements like RAPTURE are typically consumed 30 minutes to an hour before exercise to enhance energy, focus, and blood flow. However, they can also interfere with sleep and cause jitters and anxiety.

Because pre-workout products are classified as supplements, the FDA does not review them for safety or labeling accuracy before they are sold. Caffeine is a common ingredient in these supplements, but when combined with DMAA, the risk of severe cardiac strain, seizures, and even death can increase.

Despite being banned, DMAA continues to appear in sports performance products. The FDA typically discovers its presence during inspections and then offers companies the opportunity to voluntarily recall affected products.
