Adaptogens: What Are They & Do They Work?

Main Adaptogens for Stress and Brain Health

Adaptogens are a fascinating group of plants and mushrooms, with research zeroing in on a handful that stand out for their ability to ease stress and sharpen the mind. These natural remedies have been backed by clinical studies showing their potential to reduce stress and improve cognitive function.

Ashwagandha: Stress Relief and Cognitive Boost

Ashwagandha is one of the most well-studied adaptogens when it comes to stress management. This ancient herb contains withanolides, compounds responsible for its stress-reducing effects ^[3]. A study in India (December 2019 to May 2020) involved 130 participants taking 300 mg of sustained-release Ashwagandha root extract daily for 90 days. The results were impressive: participants' Perceived Stress Scale-10 scores dropped from 19.5 ± 3.2 to 13.0 ± 5.0, while their serum cortisol levels fell from 9.04 ± 3.77 μg/dL to 6.34 ± 2.31 μg/dL. They also reported better sleep and increased happiness, as measured by standardised questionnaires ^[7].

"In conclusion, Ashwagandha supplementation may improve the physiological, cognitive, and psychological effects of stress." – Heather Hausenblas, Author ^[9]

What sets Ashwagandha apart is its ability to enhance cognitive function and sleep quality without the side effects like sedation or mental dullness that are often associated with traditional stress-relief medications ^[7].

Rhodiola Rosea: Fighting Fatigue and Sharpening Focus

Known as the golden root, Rhodiola rosea is prized for its ability to combat fatigue and boost mental performance. Its active compounds, rosavins and salidroside, are key to its brain-boosting effects ^[3]. In placebo-controlled studies, participants taking Rhodiola extract showed marked improvements in reducing fatigue and enhancing mental clarity. Across various measures - stress symptoms, focus, and energy - Rhodiola consistently delivered ^[8]. It’s particularly effective for those seeking a clear mind and balanced energy without overstimulation.

Other Adaptogens Worth Knowing

Beyond Ashwagandha and Rhodiola, several other adaptogens bring unique benefits to the table:

• Schisandra chinensis: Packed with lignans and other bioactive compounds, this adaptogen supports neuroprotection, boosts stamina, enhances coordination, and protects liver function ^[10].
• Eleutherococcus senticosus (Siberian ginseng): Offers gentle stress resistance and immune support. Studies suggest it reduces symptoms of upper respiratory infections and helps manage herpes simplex virus outbreaks [20, 21].
• Holy Basil (Tulsi): A powerhouse for overall well-being, Tulsi has shown benefits in areas like blood sugar control, memory, anxiety relief, and stress management, as highlighted in a review of 24 human studies [21, 20].
• Astragalus membranaceus: Known for its immune-boosting properties, Astragalus enhances white blood cell activity, increases antibody production, and supports the body against physical and emotional stress ^[10].

Here’s a quick summary of these adaptogens and their key features:

Together, these adaptogens help the body build resilience against stress. They offer benefits like neuroprotection, fatigue reduction, and mood support, all without the risks of addiction or tolerance that can come with conventional stimulants ^[3]. What’s remarkable is their adaptability - while some, like Ashwagandha, have calming effects, others, like Rhodiola, energise - making them ideal for personalised stress management and brain health.

This understanding of adaptogens paves the way for their integration into functional products, such as the Social Blend™ by IMPOSSIBREW®, designed to bring these benefits into everyday life.

Research on Adaptogens for Stress and Brain Health

Emerging research highlights the potential of adaptogens to alleviate stress and enhance brain function. Clinical trials have shown improvements in stress markers, cognitive performance, and protective effects on the brain.

Stress Reduction and Anxiety Management

Studies have consistently shown that adaptogens can help manage stress and anxiety. A meta-analysis of nine randomised controlled trials involving 558 participants found that Ashwagandha significantly reduced stress markers compared to placebo. Results included decreases in Perceived Stress scores (–4.72), anxiety levels (–2.19), and serum cortisol (–2.58) ^[13].

"The findings from the included studies indicate that Ashwagandha formulations have beneficial effects on stress and anxiety." – Arumugam et al. ^[13]

In another 8-week study, 52 individuals experiencing chronic stress took Withania somnifera and saw notable improvements. Serum cortisol levels dropped by 16.1% after four weeks and 22.2% after eight weeks, while perceived stress levels fell by 22.1% and 32.7%, respectively ^[12]. These results highlight the potential of adaptogens to significantly reduce stress, paving the way for their role in enhancing cognitive function.

Effects on Cognitive Function

Adaptogens are not only effective in reducing stress but also in improving cognitive abilities such as memory, attention, and processing speed. A 2017 study found that taking 300 mg of Ashwagandha twice daily for eight weeks resulted in significant improvements in these areas compared to a placebo group ^[14]. Additionally, earlier studies, including a 2005 meta-analysis on Panax ginseng and a 2001 review on Bacopa, have also demonstrated enhanced cognitive performance under stress ^[11][17].

The mechanisms behind these benefits include the modulation of neurotransmitter levels, reduced oxidative stress, and enhanced neuroplasticity ^[15]. For example, clinical trials on Eleutherococcus senticosus in older adults have reported improvements in mental health and social functioning ^[16]. These effects are most impactful when adaptogens are part of a broader lifestyle that supports mental well-being ^[14].

Brain Fatigue and Neuroprotection

Beyond stress and cognitive improvements, adaptogens have shown promise in protecting the brain and combating fatigue. Research suggests that adaptogens promote neurogenesis - the growth of new brain cells - which helps the brain adapt and recover more effectively. This is particularly important as 20–25% of individuals seeking medical care for head injuries report persistent brain fatigue ^[18].

Unlike traditional stimulants, adaptogens work by triggering a mild stress response that enhances the body’s natural resilience. Studies indicate they can protect neurons from damage and may influence mechanisms involved in neurodegenerative conditions ^[3][19]. This dual effect - short-term stress relief and long-term neuronal protection - positions adaptogens as a valuable tool for maintaining mental clarity and reducing the risk of chronic stress-related complications ^[1].

These findings underline the potential of adaptogens in creating functional products that support both immediate and long-term cognitive health. With a growing body of scientific evidence, adaptogens offer a promising approach to managing stress and safeguarding brain health in today’s demanding world.

How to Use Adaptogens Safely

Using adaptogens the right way can help you make the most of their benefits while keeping risks to a minimum.

Forms and Dosages

Adaptogens are available in various forms, including capsules, powders, and tinctures, each offering distinct advantages. Capsules are a convenient option for precise dosing, perfect for those who prefer a straightforward supplement routine. Powders, on the other hand, can be mixed into smoothies, teas, or other drinks, adding flexibility to your regimen. Tinctures allow for rapid absorption and make it easy to adjust your dose as needed ^[4].

A good starting point is 300–400 mg in the morning, with gradual adjustments based on how your body responds ^[20]. For example, research on ashwagandha suggests that taking 300 mg capsules twice daily can significantly reduce cortisol levels ^[6]. Following these dosage recommendations can ensure effective and safe daily use.

Safety and Precautions

While adaptogens are generally well tolerated, it’s essential to approach their use thoughtfully, especially for certain groups. Studies show that side effects are uncommon and typically mild, such as occasional sleep disturbances, digestive discomfort, or slight changes in blood pressure ^[20].

However, not everyone should use adaptogens freely. Pregnant or breastfeeding individuals, children, and infants are advised to avoid them ^[21]. Additionally, adaptogens may interact with specific medications, including immunosuppressants, anticoagulants, and diabetes treatments ^[21]. Always consult a healthcare provider if you’re on medication, managing a medical condition, or are pregnant before adding adaptogens to your routine. Research also suggests that adaptogens are most effective when used for less than six months ^[4]. They should complement, not replace, broader strategies for managing stress effectively.

Adaptogens in Functional Products

For those looking for a convenient way to incorporate adaptogens into their daily lives, functional beverages are an appealing option. These drinks combine adaptogens with other ingredients and can make daily use more enjoyable and practical.

When choosing adaptogenic drinks, prioritise transparency and quality. Look for products that clearly list their adaptogen content and have undergone third-party testing for purity ^[22]. As Sarah Pflugradt, PhD, a Registered Dietitian, highlights:

"One of the biggest issues with adaptogenic drinks is that you have no way of knowing exactly how much of each adaptogen is in the drink" ^[22].

To address this concern, many modern adaptogenic beverages now combine adaptogens with complementary ingredients like antioxidants, probiotics, and electrolytes to boost their overall benefits ^[25]. This combination may provide a more well-rounded approach to wellness compared to single-ingredient supplements.

The rising popularity of these drinks reflects consumer interest, with the global market for adaptogenic beverages estimated at £1.56 billion in 2023 and projected to grow to £2.70 billion by 2030 ^[24]. If you’re trying these drinks for the first time, start with small amounts to see how your body reacts ^[23]. Ready-to-drink formats can also help you maintain a consistent intake, which is key to experiencing their full potential.

One example of this trend is IMPOSSIBREW®'s Social Blend™, a functional drink that combines adaptogens with ingredients aimed at promoting relaxation and long-term wellness. This product showcases how adaptogens can be seamlessly integrated into a beverage designed for both immediate stress relief and ongoing cognitive support.

The Future of Adaptogens for Stress and Brain Health

Key Takeaways

The body of scientific research supporting adaptogens continues to expand, highlighting their potential to help the body manage stress and maintain balance ^[12]. These natural compounds achieve their effects by interacting with various biological systems, including regulating neurotransmitter levels, reducing oxidative stress, and promoting neuroplasticity. Together, these mechanisms contribute to improved mental and physical health.

Clinical trials have shown promising outcomes. For instance, a systematic review and meta-analysis found that Withania somnifera (commonly known as ashwagandha) significantly reduced serum cortisol levels and improved Perceived Stress Scale scores in stressed but otherwise healthy adults after 56 to 60 days of use ^[5]. Similarly, a study involving 101 adults experiencing life-related stress reported that a four-week regimen of Rhodiola supplementation improved stress symptoms, reduced fatigue, enhanced mood, and boosted concentration and overall quality of life ^[32].

Adaptogens are also noted for their ability to normalise cortisol levels while enhancing serotonin and dopamine production. This dual action not only alleviates stress symptoms but also supports cognitive health by protecting neurons and encouraging regeneration through increased expression of neurotrophic factors like BDNF (brain-derived neurotrophic factor) ^[12].

As Dana Ellis Hunnes, PhD, MPH, RD, and senior dietitian at UCLA Health, explains:

"The claim is that adaptogens reduce our body's reaction to stress and help us adapt to stressors better." ^[2]

However, it’s worth noting that adaptogens are most effective when used for a limited period - typically less than six months - as the body may develop tolerance over time ^[4]. This highlights the importance of cycling their use and consulting with healthcare professionals, particularly for individuals managing medical conditions or taking medications ^[4][36].

With these findings in mind, the next step is to explore how the adaptogen industry is evolving and what innovations lie ahead.

What's Next

The global adaptogen market is projected to grow significantly, reaching approximately £9.9 billion by 2035 ^[37]. This growth reflects a rising interest in natural solutions for managing stress, with 59% of consumers reportedly willing to pay more for wellness-focused products ^[34].

One of the most exciting areas for adaptogens is functional beverages. Currently valued at around £103 billion globally, the functional beverage market is predicted to expand to roughly £137 billion by 2030 ^[34]. These drinks, often ready-to-drink (RTD) products, are gaining traction as convenient alternatives to traditional options. Siobhan Linney, Founder and CEO of Thirsty Gal Drinks, highlights their appeal:

"RTD and functional drinks are a dream for consumer-facing brands because they deliver instant satisfaction with zero fuss." ^[34]

Functional beverages are increasingly being positioned as replacements for alcoholic drinks, a shift that aligns with consumer interest in sustainable practices and transparent ingredient sourcing. Many people are now seeking alternatives to caffeine and alcohol that also provide long-term health benefits ^[33].

Looking forward, the industry is expected to move towards personalised adaptogen products tailored to individual health needs. However, challenges such as dosage transparency, standardisation, regulatory compliance, and supply chain management remain hurdles to overcome ^[35][37].

Emerging research is also exploring the broader therapeutic potential of adaptogens. Early findings suggest they could complement standard treatments for conditions like post-surgery recovery, congestive heart failure, and chronic obstructive pulmonary disease (COPD) ^[2]. Additionally, innovative delivery methods, such as IMPOSSIBREW®'s Social Blend™, are setting the stage for adaptogens to play a larger role in preventive healthcare and wellness-focused lifestyles.
