Stimulants
High-caffeine drinks, concentrated energy shots, and high-stim pre-workout products can look routine while carrying real risks for children, teens, athletes, and sensitive adults.
Stimulant products are often marketed as normal energy, focus, or fitness aids. The risks are easy to miss.
Some products contain large caffeine doses. Others use “energy blend” or “proprietary blend” language that makes ingredient amounts hard to understand. High-stim pre-workout and weight-loss products may also contain stimulant-related ingredients such as yohimbine, synephrine, DMHA-like ingredients, or DMAA.
The concern is not ordinary coffee or one occasional caffeinated drink for every adult. The concern is concentrated caffeine, stacked stimulants, youth use, alcohol mixing, heart symptoms, anxiety, sleep disruption, and products that contain ingredients FDA has flagged as unlawful or adulterated in dietary supplements.

FDA cites this as an amount of caffeine per day not generally associated with negative effects for most healthy adults. It is not a target and does not apply to everyone.
The American Academy of Pediatrics says caffeine and other stimulants in energy drinks have no place in children’s and adolescents’ diets.
FDA says DMAA is not a dietary ingredient and that DMHA-containing dietary supplements are adulterated.
