Survey of Nearly 3,000 U.S. Coffee Drinkers Conducted by Everyday Dose and Quantix Partners Reveals Data Supporting Scientific Insights on Caffeine Sensitivity, as Consumers Seek Smarter Ways to Fuel Their Day.
AUSTIN, Texas, Sept. 4, 2025 /PRNewswire/ -- Everyday Dose, the coffee that does more, launched a new nationwide survey with Quantix Partners revealing that more than one in three coffee drinkers regularly experience the "jitters", the anxious, heart-racing side effect many contribute to having "too much coffee." 36% of coffee drinkers report experiencing shaky hands, racing hearts, and an anxious buzz after what's supposed to be their daily boost. But science suggests the cause might run deeper, our DNA.
The survey of nearly 3,000 U.S. coffee drinkers found that caffeine sensitivity varies dramatically by age, gender, and genetics. Younger adults (ages 18-24) reported jitters at nearly five times the rate of those over 65, while over 40% of jitter-prone consumers said they were curious enough to take a DNA test to learn whether their genes were to blame.
The findings are backed by decades of research, including NIH-backed studies, showing that certain variations in the CYP1A2 gene (that about 50% of people were found to have) slow caffeine metabolism, causing its stimulating effects to last longer. For millions, that means even a single cup can bring discomfort instead of the intended energy. That is where Everyday Dose is making an impact, providing consumers with coffee that brings focus, clarity, and calm energy, without the crash or anxiety that comes with traditional coffee.
"Coffee is more than just a beverage, it's a ritual deeply embedded in our culture, with 76% of American adults drinking it daily. But for many, including myself, traditional coffee can take a toll on the body," said Jack Savage, CEO and Founder of Everyday Dose. "For years, I powered through the jitters, the crashes, and the anxiety that came with high-caffeine coffee until I realized there had to be a better way. That realization sparked the creation of a functional coffee designed to work with your body, not against it. As our new data and science continue to reinforce, today's consumers are demanding smarter, cleaner alternatives, and our functional beverage movement is just getting started."
According to the study, over 70% of Americans say they'd want to know if their DNA affects their caffeine tolerance and 41% tolerate jitters because they "need" the caffeine. This curiosity reflects a broader wellness shift: Americans are no longer willing to accept side effects as an unavoidable part of their daily ritual. Instead, they're turning to functional, science-backed beverages.
Below are additional highlights from the survey showcasing how consumers who are caffeine sensitive are looking for new strategies to cope with jitters:
- 67% of those who are caffeine sensitive have cut back on their coffee intake
- 66% of those who get jitters have considered switching to an alternative like matcha, tea or mushroom coffee. Alternatives tried include: decaf (55%), matcha (38%), mushroom coffee (22%), L-Theanine (18%) and more.
- 47% of those who are caffeine sensitive only drink coffee with food
