Adaptogens are having a moment. They're in lattes, supplements, protein bars, and skincare. Which means they're also surrounded by a significant amount of noise — overclaiming, vague marketing language, and a general sense that if you just take this thing, something good will happen.
So let's be clear about what adaptogens actually are, what they actually do, and how to think about whether they're worth adding to your life.
The actual definition
The term adaptogen was coined in 1947 by Soviet pharmacologist Nikolai Lazarev. To qualify as an adaptogen, a substance must meet three criteria: it must be non-toxic at normal doses, it must help the body resist physical and emotional stress, and its effect must be non-specific — meaning it supports the body broadly rather than targeting one isolated symptom.
That last point is important. Adaptogens don't work the way pharmaceuticals do, by blocking or stimulating a specific receptor. They work more like a thermostat — helping the body find its own equilibrium under pressure. If your cortisol is too high, an adaptogen helps bring it down. If your energy is depleted, the same herb may help restore it. The action depends on what the body actually needs.
The most researched ones
Ashwagandha (Withania somnifera) is probably the most studied. Multiple clinical trials have shown measurable reductions in cortisol, improvements in sleep quality, and reduced anxiety scores in people who take it consistently. The key word is consistently — most of the research shows effects emerging over four to eight weeks of daily use.
Rhodiola rosea has strong evidence for reducing fatigue and improving cognitive function under stress — particularly relevant for people dealing with burnout or mental exhaustion.
Holy basil (tulsi) has been used in Ayurvedic medicine for thousands of years as a rasayana — a rejuvenating tonic — and modern research supports its effects on cortisol regulation and immune function.
What they won't do
Adaptogens are not a substitute for sleep, food, movement, or rest. They work best as a complement to a lifestyle that's at least trying to support the body — not as a way to keep pushing through conditions that are genuinely depleting you.
They also take time. If you try an adaptogen for three days and feel nothing, that tells you very little. The body needs weeks to recalibrate. This is plant medicine, not a stimulant.
How to start
The simplest starting point is to pick one and use it daily for a month. Notice what changes — and what doesn't. Keep other variables as stable as possible so you can actually hear the signal.
CALMA is built around adaptogenic and nervine herbs specifically chosen for nervous system support. NOURISH focuses on mineral-rich plants that work at the cellular level — a different kind of adaptation, but equally foundational.
Start where your body is asking for the most support. That's usually the right answer.
