Adaptogens are natural herbs and roots that help your body manage stress and support your immune system. Chronic stress weakens immunity, leaving you more prone to illness. Adaptogens work by balancing stress hormones, reducing inflammation, and improving immune response. Popular options include:
- Ashwagandha: Calms stress, improves sleep, and boosts immune markers.
- Rhodiola Rosea: Increases energy, reduces fatigue, and protects cells.
- Reishi Mushroom: Activates immune cells and fights inflammation.
- Tulsi (Holy Basil): Strengthens immunity with antibacterial and antiviral properties.
- Astragalus: Enhances immunity and provides antioxidant protection.
These herbs support immune resilience by regulating stress, fine-tuning immune responses, and reducing inflammation. While generally safe, consult a healthcare provider before use, especially if pregnant, nursing, or on medication.
Adaptogens: The Ultimate Immune System Hack
Top Adaptogenic Herbs for Immune Support
Adaptogenic herbs have been widely recognized for their ability to support the immune system in unique ways. Each herb brings its own set of benefits, and understanding their specific properties can help you decide which ones align with your needs.
Ashwagandha
Ashwagandha is known for its calming effects, making it an excellent choice for evening use. Unlike stimulating herbs, ashwagandha contains compounds like withanolides that help soothe the brain, reduce inflammation, lower blood pressure, and regulate immune function [7]. A 2023 clinical review highlighted how these compounds influence cytokine production and activate immune cells, supporting a balanced immune response. Ashwagandha has also been shown to elevate key immune markers and may counteract stress-related suppression of the immune system [10]. Beyond immunity, it’s also associated with better sleep quality and reduced stress and anxiety [7].
Rhodiola Rosea
Often referred to as arctic root or golden root, Rhodiola rosea is a stimulating adaptogen best suited for morning use [9]. Its root contains over 140 active compounds, with rosavin and salidroside being the most prominent [3]. Rhodiola helps the body adapt to both physical and mental stress and is thought to combat fatigue effectively [3]. Additionally, it may protect cells from damage and help regulate heart rhythms [8]. For optimal results, take Rhodiola on an empty stomach, but avoid it before bedtime. Most supplements contain 100 to 200 mg per dose, standardized to 3% rosavins and 0.8–1% salidroside [3].
Reishi Mushroom
Reishi mushroom is a powerful ally for immune health, working by influencing immune cell activity. It supports the immune system by affecting the genes in white blood cells, which play a critical role in immune defense [4]. Studies show that reishi (Ganoderma lucidum) enhances immune function by activating natural killer (NK) cells and promoting cytokine production [10]. These actions help balance the immune response, reduce chronic inflammation, and provide antioxidant protection against oxidative stress [4].
Tulsi (Holy Basil)
Tulsi, or holy basil, has been revered for centuries in traditional medicine. Devon Peart, a registered dietitian at Cleveland Clinic, notes:
"Tulsi has been used for thousands of years in India and Nepal for its medicinal properties. It's been called 'The Elixir of Life,' 'Liquid Yoga,' and 'Queen of the Herbs,' and it's listed in the Journal of Ayurveda and Integrative Medicine for its many benefits." [5]
Tulsi’s antibacterial, antiviral, and antifungal properties make it an excellent choice for strengthening immune defenses [5][6]. A double-blinded, randomized clinical trial demonstrated that tulsi extract significantly improved Th1-type immune responses, suggesting better regulation of cytokine balance and lymphocyte activity [10]. As a calming adaptogen, tulsi is often recommended for evening use, especially during periods of heightened stress [9]. Peart suggests trying holy basil tea or organically grown tulsi for a soothing experience [5].
Astragalus
Astragalus has a long history of use in supporting immune function. A 2020 clinical review found that astragalus polysaccharides enhance immune responses at multiple levels - impacting organs, cells, and molecules to support both innate and adaptive immunity. It also offers antioxidant properties that help combat oxidative stress, further strengthening immune health [10]. This combination of broad immune support and antioxidant activity makes astragalus a strong choice for building overall resilience.
How Adaptogens Work: Mechanisms of Immune Support
Adaptogens play a fascinating role in strengthening the immune system by managing stress hormones, fine-tuning immune responses, and reducing inflammation. Let’s break down how they work.
Stress Hormone Regulation
One of the key ways adaptogens support the body is by helping it handle stress more effectively. They interact with the hypothalamic-pituitary-adrenal (HPA) axis, which is responsible for managing the stress response and keeping the body balanced[12][2]. When the HPA axis is overactive for too long, it can weaken the immune system. Adaptogens work to bring chronically high cortisol levels back to normal, shielding cells from its damaging effects and restoring equilibrium to the HPA axis[11][12]. This sets the stage for a stronger immune system.
Immune Modulation
Adaptogens don’t stop at managing stress - they also directly influence immune function. By adjusting both innate and adaptive immune responses, they help maintain a well-balanced defense system[14]. For instance, adaptogens enhance the activity of T regulatory cells, which are crucial for controlling the immune response and preventing excessive inflammation[13]. They also impact gene expression related to the body's stress response, aiding in vital cellular processes and survival[15]. Research from Russia even found that daily use of eleuthero, a popular adaptogen, reduced respiratory illnesses by up to 50%[13].
Anti-Inflammatory Benefits
Chronic inflammation poses a major challenge to a healthy immune system, and adaptogens help by reducing low-grade inflammation and oxidative stress[10]. Long-term stress can lead to cortisol resistance, which not only increases inflammation but also lowers the activity of natural killer (NK) cells - key players in immune defense[16]. Clinical studies highlight this effect: an 8-week randomized, double-blind trial revealed that 1.68 grams of cordyceps extract boosted NK cell activity by 39% compared to a placebo. Similarly, panax ginseng showed a 35% increase in NK cell activity at 8 weeks and a 40% increase at 14 weeks[16].
"Adaptogens have a normalizing action irrespective of the direction of the pathologic state. Stress is really not a good thing for our immune system. One of the most important things we can do is use adaptogens." - Lise Alschuler, N.D.[16]

Adding Adaptogens to Your Daily Routine
Now that you know how adaptogens can help support your immune system, the next step is figuring out how to integrate them into your daily life. The process involves choosing the right adaptogen for your needs, understanding proper dosages, and following essential safety guidelines.
Choosing the Right Adaptogen
The first step is to identify your primary health goal. For example, Rhodiola is ideal for boosting energy and focus, while Ashwagandha is better suited for managing stress and improving sleep. These adaptogens work differently to help maintain balance in your body. Rhodiola is great for those looking for sustained energy without feeling overstimulated, while Ashwagandha is often recommended for calming high cortisol levels and enhancing sleep quality.
As Kayla Martin, MS, CNS, explains:
"Essentially, adaptogens work like a thermostat for the body's stress response, helping to modulate and respond to whatever's going on internally or externally." [17]
Once you’ve identified the right adaptogen for your needs, consider the form and dosage that work best for your routine.
Forms and Dosage
Adaptogens come in a variety of forms, including supplements, teas, and powders. Powders can easily be added to smoothies or meals, making them a convenient morning option for their energizing properties. Some adaptogens, like dried astragalus root or whole reishi mushrooms, can be used in their natural form - perfect for soups or stews. Meanwhile, adaptogens like reishi are often taken in the evening to promote relaxation and better sleep.
When starting out, follow the dosage instructions on the product label and stick to one adaptogen at a time to monitor how your body responds. Always choose high-quality, third-party tested products to ensure safety and effectiveness.
Safety and Precautions
While adaptogens are generally well-tolerated, it’s important to incorporate them carefully into your routine to avoid potential side effects or interactions. Some people may experience mild reactions like digestive discomfort, headaches, or allergies. In rare cases, ashwagandha has been linked to liver issues [18]. Additionally, adaptogens can interact with medications, such as blood thinners or hormone therapies, and may impact conditions like hypertension, diabetes, or thyroid disorders.
Dr. Dana Ellis Hunnes, PhD, MPH, RD, from UCLA Health emphasizes:
"I tell patients not to go and take just any herbs and supplements, because they may interact with your medication. Your body's reaction to those things may do more harm than good." [2]
Certain groups need to be especially cautious. Pregnant and breastfeeding women, individuals with unstable blood pressure, those with autoimmune conditions (particularly thyroid-related), and anyone preparing for surgery should avoid adaptogens unless advised otherwise by a doctor. Children and older adults should also use them with care.
Before making adaptogens a regular part of your routine, consult your healthcare provider - especially if you’re managing chronic conditions, taking medications, or are pregnant or breastfeeding. Remember, adaptogens are meant to complement your wellness efforts, not replace professional medical care.
Scientific Evidence and Considerations
Adaptogens have become increasingly popular, but understanding the scientific research behind them is crucial for making informed choices about adding them to your wellness routine. While studies highlight their potential, there are also important limitations to keep in mind.
Research Findings on Adaptogens
Research suggests that adaptogens may help boost immune resilience through specific biological mechanisms. They appear to strengthen the body's response to stress by influencing the immune-neuro-endocrine system [20]. This includes activating key immune cells like macrophages, T-lymphocytes, and natural killer (NK) cells, which play a vital role in cellular defense and communication [20].
Alexander Panossian, a prominent researcher in this area, explains how adaptogens may regulate stress:
"Adaptogens might normalize chronically elevated cortisol/corticosterone levels, presumably through their interaction with the glucocorticoid receptors, helping to restore the balance of the HPA-axis." [11]
One study focused on ADAPT-232 - a blend of extracts from Rhodiola rosea, Schisandra chinensis, and Eleutherococcus senticosus. The results showed a concentration-dependent increase in the lifespan of C. elegans, hinting at possible longevity benefits [14]. This is especially relevant given that a 2021 global survey found 41% of adults reported high stress levels [11]. Adaptogens may also support immune health by balancing cellular and humoral immunity and influencing cytokine activity [20]. Such findings align with their historical use in traditional medicine systems in India, China, Korea, and Japan for enhancing stress resistance [11].
While these insights are encouraging, there are notable challenges and limitations in the research.
Limitations and Individual Variability
Despite the promising evidence, adaptogen research has its shortcomings. Many studies rely on animal models, making it hard to predict their effects in humans. Human studies, when conducted, are often small, lack proper randomization, or fail to define precise dosages [19]. Dr. Rashmi Mullur, Assistant Professor of Medicine at UCLA, highlights this issue:
"They can just say it works. They can sell it or they can spend a bunch of money to study it and potentially find that it has no benefit. There's too much risk." [19]
Other challenges include the inconsistent molecular makeup of adaptogens, making it difficult to standardize dosages across products. Long-term safety data is also scarce, and the broad definition of "stress" in research can oversimplify findings. In some cases, adaptogens' immunomodulatory or cognitive effects complicate their classification, making it harder to interpret results [19]. Additionally, clinical trials often fail to capture the interconnected nature of adaptogens' effects, highlighting the need for global standardization in research [21]. Poor market regulation adds another layer of concern, as some adaptogens may carry serious, yet poorly understood, side effects [19].
Complementary Role of Adaptogens
Adaptogens work best as part of a broader healthy lifestyle. Their effects can vary widely between individuals and are most noticeable when combined with a balanced diet, regular exercise, quality sleep, and effective stress management strategies [22]. Factors like individual health goals, existing conditions, and unique biochemistry all play a role in how adaptogens impact the body. Starting with a low dose and observing your reaction is a sensible approach [22].
It’s also important to recognize that adaptogens are not risk-free [19]. Certain conditions, such as pregnancy, nursing, or autoimmune disorders, may require extra caution - or complete avoidance - when using these supplements [22]. If you're on medication, consult your healthcare provider to avoid potential interactions, as adaptogens can affect drug metabolism [22].
When selecting adaptogens, choose products from reputable brands that clearly disclose their sourcing, manufacturing processes, and testing standards. Stay updated on the latest research, and if you notice adverse effects, discontinue use and consult a doctor promptly [22].
Conclusion: Building Immune Resilience with Adaptogens
Adaptogens play a key role in strengthening your body's ability to manage stress and fend off illness. These herbs help your body adjust to both physical and emotional challenges, acting as a steady partner for your immune system during tough times. Researchers describe adaptogens as “herbal preparations that increased attention and endurance in fatigue, and reduced stress-induced impairments and disorders related to the neuro-endocrine and immune systems” [10].
The magic of adaptogens lies in their ability to balance your immune response. When stress or illness leaves your immunity weakened, or when excessive inflammation causes an overreaction, adaptogens step in to normalize these responses. By calming your stress levels and restoring balance to the systems tied to immunity, they create a foundation for better health [10].
Adaptogens are particularly effective at managing the impact of chronic stress on the immune system. They support the hypothalamic-pituitary-adrenal (HPA) axis, helping to regulate cortisol levels and promote stronger immune resilience. This makes them a valuable tool for maintaining overall well-being.
That said, adaptogens are most impactful when used as part of a broader wellness plan. Pairing them with a nutritious diet, regular exercise, good sleep, and stress-relief practices enhances their benefits [23]. Dr. Lise Alschuler, N.D., explains:
"Adaptogens have a normalizing action irrespective of the direction of the pathologic state. Stress is really not a good thing for our immune system. One of the most important things we can do is use adaptogens." [16]
For best results, adaptogens should be used for short periods - ideally less than six months - and starting with low doses is recommended. They’re available in various forms, like capsules, teas, and powders that can be added to meals [1][24]. Consistency is key, as adaptogens work gradually to bring your body back into balance [23].
Ultimately, adaptogens highlight an important truth: true immune health is about achieving balance - not just within the immune system, but across the interconnected systems of your body and mind [10]. This approach focuses on addressing the root causes of health issues rather than simply treating symptoms.
