A 2025 deep-dive into America’s booming love affair with caffeine-free and mushroom coffee alternatives
TL;DR
- Hawaii, Nevada and Georgia lead the nation in Google searches for “mushroom coffee,” a popular caffeine-light drink that swaps roasted beans for functional mushrooms.
- Searches for “caffeine-free coffee” have doubled nationwide since 2020, reflecting growing concerns about jitters, sleep disruption and blood-sugar swings.
- Younger Millennials (ages 27-35) and Gen Z are the demographic engines of the shift, according to proprietary survey data.
- Clinical evidence suggests that reducing daily caffeine to ≤100 mg can improve sleep efficiency, lower resting blood pressure and calm cortisol spikes.¹²
Why Americans Are Rethinking Their Caffeine Habit
Caffeine has long been the go-to boost for working parents, students and athletes. Yet 2025 data show a tectonic shift toward “calmer” cups:
Drivers include:
-
Health & wellness: After the pandemic, consumers prioritized sleep, cortisol balance and stable blood sugar.
-
Wearables data: Oura- and WHOOP-wearers can see how late-day caffeine trashes their HRV and deep-sleep scores.
-
Functional beverages boom: Mushroom coffee, adaptogenic lattes and chicory blends promise focus without the “wired-tired” crash.
How We Measured “Caffeine Flight”
We compiled Google Trends “interest by sub-region” scores for three long-tail pillars between Jan 2020 and Jul 2025:
-
“caffeine-free coffee”
-
“mushroom coffee”
-
“adaptogenic coffee”
Trends scores are scaled 0-100; a 50 means that state searches at half the volume of the top state that week. To find who’s ditching caffeine fastest, we focused on 2025 YTD averages for mushroom coffee—the clearest proxy for a true bean-less switch.
Health Benefits of Going Low-Caffeine
Switching from 3–4 cups of drip coffee (≈350 mg caffeine) to a mushroom-based, caffeine-light drink (<50 mg) can pay off quickly:
-
Better sleep efficiency — A randomized crossover trial found that cutting caffeine after 2 pm improved deep-sleep by 17 %.¹
-
Lower resting BP — A 2024 meta-analysis reported a 4.8 mm Hg systolic drop when daily caffeine fell below 100 mg.²
-
Calmer cortisol curve — Early-morning caffeine spikes ACTH, but adaptogens like Reishi and Cordyceps tame the surge.³
-
Stable blood sugar — Elevated catecholamines from caffeine can trigger post-meal glucose swings; lower-caffeine blends blunt the effect.⁴
