What Are Adaptogens?
The term “adaptogen” was first coined in 1947 by Russian scientist Dr. Nikolai Lazarev. He described them as substances that help the body “adapt” to stress—whether physical, chemical, or biological .
The stress response that adaptogens target is closely connected to your nervous system. For a deeper understanding of how your body handles stress, you may want to explore our guide on the vagus nerve and how activating your body’s relaxation response can support emotional balance.
Key Characteristics of Adaptogens
For a substance to be classified as an adaptogen, researchers generally agree it should meet three criteria :
Criterion Description
Non-toxic Safe for regular use at normal doses
Non-specific Helps the body handle multiple types of stress
Normalizing Brings the body back toward balance (homeostasis)
How Adaptogens May Work
Research suggests adaptogens influence the hypothalamic-pituitary-adrenal (HPA) axis—the complex system that controls your body’s stress response .
Dr. Brenda Powell, an integrative medicine specialist at the Cleveland Clinic, explains: “Adaptogens seem to help regulate cortisol and other stress hormones, potentially helping the body respond more efficiently to stressors without becoming depleted” .

Popular Adaptogens and What Research Suggests
Ashwagandha (Withania somnifera)
Ashwagandha is one of the most studied adaptogens, with roots in Ayurvedic medicine dating back thousands of years.
What research indicates:
A 2019 randomized controlled trial published in Medicine found that participants taking ashwagandha extract showed significantly lower cortisol levels compared to placebo after 60 days .
Another systematic review in the Journal of Alternative and Complementary Medicine concluded that ashwagandha appears to be safe and may help reduce stress and anxiety, though more research is needed .
Key findings from studies:
· May help reduce cortisol levels (14-28% reduction in some studies)
· Associated with improved sleep quality in some participants
· May support mental clarity and focus
Rhodiola Rosea
Rhodiola grows in cold, mountainous regions of Europe and Asia and has been used traditionally to increase stamina and fight fatigue.
What research indicates:
A 2017 study in Frontiers in Nutrition found that rhodiola supplementation was associated with reduced mental fatigue and improved attention in participants experiencing stress .
Research published in Phytomedicine suggests rhodiola may help with:
· Stress-related fatigue
· Mental performance during stressful situations
· Exercise recovery
Holy Basil (Ocimum sanctum / Tulsi)
Holy basil, or tulsi, is considered a sacred plant in India and has been used in Ayurvedic medicine for centuries.
What research indicates:
A 2017 review in the Journal of Ayurveda and Integrative Medicine found that holy basil contains compounds with potential stress-reducing properties .
Studies suggest it may:
· Support healthy stress response

The Science Behind Stress and Adaptogens
Understanding the Stress Response
When you encounter a stressor—whether physical danger, work pressure, or lack of sleep—your body activates the HPA axis. This triggers a cascade of hormones, including cortisol and adrenaline, preparing you to face the challenge .
This response is designed to be short-term. Problems arise when stress becomes chronic, keeping these systems activated long after they’re needed .
Chronic stress doesn’t just affect how you feel—it can impact your physical health in measurable ways. Our article on cortisol and how this stress hormone affects sleep, weight, and energy explores the science behind stress from another angle.
Where Adaptogens May Help
Research suggests adaptogens may influence this system in several ways :
Potential Effect What Research Suggests
Cortisol regulation May help maintain healthy cortisol patterns
Cellular protection Some adaptogens have antioxidant properties
Energy metabolism May support mitochondrial function
Neurotransmitter balance Could influence mood-regulating brain chemicals
It’s important to note that individual responses vary significantly, and most research has been conducted in relatively small studies.

Safety Considerations and Side Effects
General Safety Profile
Most adaptogens appear to be safe for short-term use in healthy adults when taken as directed. However, “natural” doesn’t automatically mean “safe for everyone” .
Potential Side Effects
Adaptogen Possible Side Effects
Ashwagandha Digestive upset, drowsiness (rare)
Rhodiola Dizziness, dry mouth, agitation (rare)
Holy Basil Generally well-tolerated
Who Should Be Cautious
Certain groups should consult a healthcare provider before taking adaptogens:
· Pregnant or breastfeeding women — safety not well established
· People with autoimmune conditions — may affect immune activity
· Those taking medications — especially thyroid, diabetes, or blood pressure medications
· Individuals with hormone-sensitive conditions — some adaptogens may affect hormones

How to Approach Adaptogens Wisely
Quality Matters
The supplement industry isn’t regulated like pharmaceuticals. Products can vary widely in quality.
What to look for:
· Third-party testing seals (USP, NSF, ConsumerLab)
· Clear labeling of active ingredients
· Reputable brands with good manufacturing practices
Start Low, Go Slow
If you’re curious about trying adaptogens:
1. Choose one herb at a time (not combinations)
2. Start with a low dose as recommended on the label
3. Pay attention to how your body responds
4. Keep a simple journal noting any changes in energy, mood, or stress
5. Consult a healthcare provider before continuing long-term
The Placebo Consideration
Research on stress and supplements is complicated by the placebo effect . If you take something believing it will help you feel less stressed, you might actually feel less stressed—even if the herb itself has no direct effect.
This doesn’t make the experience “fake,” but it’s important to interpret results honestly.

Common Questions About Adaptogens
Can I take adaptogens with my regular medications?
Always consult your healthcare provider before combining supplements with medications. Some adaptogens can interact with:
· Blood pressure medications
· Diabetes medications
· Thyroid medications
· Antidepressants
How long until I notice effects?
Individual responses vary significantly. Some people report feeling differences within days, while others may need several weeks of consistent use. Research studies typically run 4-12 weeks .
Are adaptogens safe for long-term use?
Long-term safety data is limited for most adaptogens. While traditional use spans centuries for some herbs like ashwagandha and holy basil, modern research on extended use is still developing .
Do I need to cycle adaptogens?
Some experts suggest cycling adaptogens (taking breaks periodically), though evidence for this practice is limited. Following package directions or healthcare provider guidance is recommended.
Can adaptogens replace stress management practices?
No. Adaptogens should be viewed as potential supplements to—not replacements for—established stress management practices like:
· Adequate sleep
· Regular physical activity
· Healthy eating patterns
· Social connection
· Mindfulness or relaxation practices

Conclusion
The growing interest in adaptogens reflects something important: people are looking for natural ways to support their health in a stressful world. This desire is understandable and valid.
The science of adaptogens is still evolving. While promising, much of the research remains preliminary. What works for one person may not work for another—and that’s perfectly normal.
Whether you choose to explore adaptogens or not, the foundations of stress management remain unchanged: adequate sleep, nutritious food, regular movement, meaningful connections, and time for restoration.
No herb can replace these fundamentals. But for some people, adaptogens may offer additional support along the way.
As always, approach with curiosity, informed skepticism, and guidance from qualified healthcare professionals.
