A new study suggests that a single dose of ashwagandha, a traditional herb widely used in Ayurvedic medicine, could enhance cognitive performance and mood within an hour, with effects lasting after a month of use. The findings, published in Nutrients, have sparked interest among health-conscious Thai readers and supplement enthusiasts. Research by a team led by Megan Leonard tested a liposomal form designed to maximize absorption, reflecting a growing Thai market for scientifically backed herbal products.
Ashwagandha, known scientifically as Withania somnifera, has long been valued as an adaptive herb that helps the body cope with stress. In Thailand, it is often referred to as สมุนไพรอาชวกันดา and popularly called “Indian ginseng” for its reputed resilience-boosting properties. The root is the main source for extracts used in both traditional remedies and modern dietary supplements sold in Thai pharmacies and wellness shops.
The study recruited 59 healthy young adults with an average age of 23, evenly split between men and women. Participants received either 225 mg of liposomal ashwagandha extract or a placebo daily for 30 days in a double-blind setup. Cognitive performance was assessed with the Computerized Mental Performance Assessment System, while mood was measured using the Profile of Mood States at three intervals: before supplementation, one hour after the first dose, and after 30 days of use. The ashwagandha group showed improvements in memory, attention, vigilance, and executive function, along with lower tension and fatigue compared with the placebo group. Notably, benefits appeared within an hour of the initial dose.
Authors cautioned that the study sample was small and limited to healthy young adults, recommending further research across broader populations. Nevertheless, the results resonate with Thai readers who seek safe ways to support mental performance, particularly students and professionals juggling time-sensitive tasks. In Thailand, “brain booster” supplements are already popular, though experts remind consumers that evidence varies by product quality and dosage.
Thai medical professionals emphasize cautious, informed use. A neurologist from a leading Bangkok hospital notes that consumers should prioritize products supported by solid research, quality certification, and awareness of potential drug interactions. Thai urban millennials and Gen Z consumers tend to favor evidence-based approaches to herbal supplements and often prefer standardized dosages.
Global interest in ashwagandha mirrors a broader reappraisal of ancient remedies through modern science. While randomized trials have linked ashwagandha with reduced stress and improved sleep, findings on cognition depend on formulation, dose, and population. Previous studies have reported improvements in working memory and reaction times at certain doses, supporting but not guaranteeing all claimed benefits.
Traditional Thai medicine has its own herbs associated with brain health, such as bacopa monnieri and ginkgo biloba. The rising popularity of ashwagandha in urban Thailand reflects a blend of curiosity and a demand for scientifically validated wellness solutions. Consumers should avoid relying on unverified claims and select products from reputable sources. Side effects are uncommon but can include digestive upset or drowsiness at higher doses, and there may be interactions with certain medications.
Looking ahead, researchers aim to explore whether similar cognitive benefits extend to older adults, people with mild cognitive impairment, or individuals under chronic stress. If confirmed, ashwagandha could become a low-risk option in cognitive health strategies alongside sleep, nutrition, exercise, and mental engagement.
For readers considering trying ashwagandha, consult a healthcare professional first, especially if you have underlying health issues or take prescription medications. Choose standardized products with clear extract dosages, roughly in the 225–400 mg range used in research. Avoid overclaiming benefits and adhere to recommended dosages. The Thai phrase “ใช้แต่พอดี” (use only as needed) captures the pragmatic approach many Thai consumers take toward supplements. Remember that good sleep, balanced meals, regular activity, and mental challenges remain foundational to cognitive wellbeing.
In summary, ashwagandha’s story illustrates how Thai culture embraces evidence-based adaptations of traditional wisdom. As further studies unfold, Thai readers can thoughtfully assess whether this ancient herb fits into their personal health plans—mindful of quality, safety, and realistic expectations.
