The Era of "Proprietary Blends"
During this time period, it was common practice for manufacturers to group multiple ingredients under a label called a "proprietary blend." This allowed companies to hide the exact amounts of each ingredient from the consumer, making it impossible for individuals to know precisely what they were putting into their bodies.
What was DMAA?
The defining ingredient of the supplements involved in the early 2010s FDA interventions was 1,3-dimethylamylamine (DMAA).
The Mislabeling
Companies initially claimed DMAA was a naturally occurring extract from the geranium plant. Independent scientific analysis later revealed that the DMAA used in these products was actually created in laboratories. Because it was synthetic, it should have been classified and regulated as a drug, not sold over-the-counter as a dietary supplement. Consumers were completely unaware of this.
The Physiological Effect
DMAA acts as a vasoconstrictor, meaning it narrows the blood vessels. At the same time, it elevates the heart rate. When individuals took these supplements before vigorous exercise, this combination placed an unexpected and severe strain on the cardiovascular system that the body could not safely regulate.
Recognizing the Issue
As these specific formulas gained widespread popularity, medical professionals began noticing a pattern. The chart below reflects the number of reports sent to the FDA during those years, prompting the medical and regulatory communities to begin investigating these products.

Reflecting the timeline of product popularity and subsequent investigations.
A Systemic Failure, Not a Personal One
It is important to understand that consumers taking these products were following the printed instructions. The individuals affected by these supplements were often healthy, active people who trusted that products sold on the shelves of major health stores were safe and tested.
The adverse effects were caused by the undisclosed potency and chemical nature of the ingredients, combined with the physical exertion of exercise. It was a failure of transparency and regulation, leaving the consumer unable to make an informed choice about the physical toll the product would take.
The Regulatory Correction
Once the medical community identified the link between these supplements and the health risks, authorities stepped in to remove them from the market. This timeline shows how the issue was finally addressed.
Department of Defense Action
After observing health incidents among service members, the military acted swiftly, removing all products containing DMAA from stores on military bases worldwide to protect their personnel while a safety review was conducted.
FDA Intervention
The FDA officially stepped in, issuing formal warning letters to manufacturers. They clarified that DMAA was an unapproved, synthetic substance and posed an unmitigated risk to consumers, requiring companies to halt production.
Market Removal
Facing strict orders from the government, the major manufacturers finally agreed to destroy their remaining warehouse inventories of products containing DMAA, ensuring they could no longer be sold to the public.
Legal Accountability
The Department of Justice followed up with legal action against the executives who had knowingly mislabeled synthetic chemicals as natural extracts. The industry saw a significant shift toward transparency and stricter oversight as a result of this era.
