The Class 3 supplement item listed is?

• A. Edhedra /DMAA
• B. Vitamin B12
• C. Creatine
• D. Omega-3

Answer: (A)

Some supplements raise safety concerns for aircrew because they can cause strong physiological and cognitive effects that could impair performance. Ephedra-containing products, and specifically the stimulant DMAA, are known to significantly raise heart rate and blood pressure, increase the risk of tachyarrhythmias or stroke, and produce anxiety or insomnia. These effects are dangerous in flight, where rapid decision-making, stable cardiovascular function, and consistent vigilance are essential. Because of that, these ingredients are treated as high-risk and often require strict review or are banned in aviation medical standards. Other options listed—Vitamin B12, Creatine, and Omega-3 fatty acids—do not carry the same acute safety risks for most people. They’re generally regarded as safe and don’t trigger the same level of concern in flight-safety contexts. Therefore, the item classified as Class 3 among supplements is the Ephedra/DMAA-containing product.
