In a past study, 14 young adults consumed 1 gram of Cordyceps before high-intensity interval exercise. The result? Less muscle damage and faster cell repair, according to Zoe. A small trial hints at adaptogens' potential under controlled conditions, yet it's a mere glimpse of the evidence needed for broad health claims.
Adaptogen-infused beverages are exploding in popularity, touting diverse health benefits. But most scientific backing comes from preliminary animal or in-vitro studies, not robust human clinical trials. The market surge often outpaces the foundational science still required.
The adaptogen market will likely continue its rapid ascent, fueled by consumer demand. However, regulators and consumers will increasingly push for rigorous, transparent human studies to validate efficacy and safety. Increased scrutiny from regulators and consumers will inevitably lead to a shake-out, weeding out less substantiated products.
What Are Adaptogens, Anyway?
Adaptogens are natural substances believed to help the body adapt to stress and maintain balance. Animal and isolated neuronal cell studies show they can be neuroprotective, anti-fatigue, antidepressive, anxiolytic, nootropic, and CNS stimulating, according to PMC. The wide array of effects points to their complex biological pathways, yet translating these lab observations to consistent human benefits remains a significant challenge.
Specific compounds drive these effects. ScienceDirect, for instance, reports Cordyceps militaris powder contains 1373.21 mg/100 g of cordycepin and 511.15 mg/100 g of adenosine. Cordycepin and adenosine are central to adaptogens' purported benefits. However, simply identifying these compounds doesn't guarantee their efficacy in the typical, often lower, doses found in consumer beverages.
The Science of Stress and Immunity: Early Insights
Early animal research offers a mechanistic basis for adaptogens' traditional roles in stress management and immune support. Ashwagandha, for example, decreased urinary stress markers in animal models. Similarly, rats given rasayana before chronic stress showed smaller rises in corticosterone and fewer gastric ulcerations, according to VA. Early animal research suggests adaptogens can mitigate physiological stress responses in controlled environments, but whether these effects scale to human well-being is still an open question.
