In my personal opinion, it is a safe and natural supplement with many benefits for health and human performance, backed by 20 years of scientific research, and astonishingly human consumption that dates back 4000 years.
Here is a summary of the scientific research specific to muscle function and optimization:
1. Kulkarni C, Patki P, Jog V, Gandage S, Patwardhan B (1991)
"Treatment of osteoarthritis with a herbomineral formulation: a double-blind, placebo-controlled, cross-over study."
Journal of Ethnopharmacology, 33(1-2), 91-95.
Results: This pioneering study involved participants suffering from osteoarthritis who were treated with a formulation that included ashwagandha. The findings demonstrated significant reductions in joint pain and improvements in functional mobility. The results indicated that ashwagandha could provide musculoskeletal benefits, positively impacting muscle function indirectly through enhanced joint health.
2. Raut AA, Rege NN, Tadvi FM, Solanki PV, Kene KR, Shirolkar SG, Pandey SN, Vaidya RA (2012)
"Exploratory study to evaluate tolerability, safety, and activity of Ashwagandha (Withania somnifera) in healthy volunteers."
Journal of Ayurveda and Integrative Medicine, 3(3), 111-114.
Results: In a trial with 50 healthy volunteers, ashwagandha was shown to be well-tolerated, and participants reported improvements in vitality and decreased fatigue. While the primary focus was on safety and tolerability, these findings suggest the herb's potential to enhance physical performance and recovery due to its ability to reduce stress and improve overall well-being.
3. Choudhary B, Shetty A, Langade D (2015)
"Efficacy of ashwagandha (Withania somnifera Dunal) in improving cardiorespiratory endurance in healthy athletic adults."
Ayurveda and Integrative Medicine, 6(3), 137-144.
Results: This randomized controlled trial assessed 20 athletic adults and found that ashwagandha supplementation significantly improved cardiorespiratory endurance, as measured by peak oxygen uptake (VO₂ max). Participants exhibited better endurance performance on various physical tasks, indicating that ashwagandha can contribute to enhanced aerobic capacity, vital for athletic performance.
4. Wankhede S, Langade D, Joshi K, Sinha SR, Bhattacharyya S (2015)
"Examining the effect of Withania somnifera supplementation on muscle strength and recovery: a randomized controlled trial."
Journal of the International Society of Sports Nutrition, 12, 43.
Results: In a study involving 66 male participants engaged in resistance training, those supplemented with 300 mg of ashwagandha daily exhibited a 1.5-fold increase in one-repetition maximum (1RM) strength compared to the placebo group. Additionally, muscle size increased significantly, and biomarkers of muscle damage, such as creatine kinase, were notably lower in the ashwagandha group, indicating enhanced recovery.
5. Shah YC, Trivedi MH, Patel SG, Mathuria N, Sitharaman MR (2018)
"Clinical Evaluation for the Improvement of Muscle Strength and Neuromuscular Coordination in Chronic Generalized Weakness with Ashwagandha root powder."
Journal of Ethnopharmacology, 227, 123–132.
Results: This clinical study involved individuals experiencing chronic weakness and assessed improvements in muscle strength and neuromuscular coordination. Participants taking ashwagandha showed significant increases in muscle strength measured through dynamometric assessments and exhibited improved performance in specific neuromuscular coordination tasks, confirming ashwagandha's effectiveness in enhancing muscle function.
6. Bhatia M, Rana AC, Kumar R, Gupta M (2018)
"Beneficial Effects of Withania somnifera on Strength, Muscle Mass, and Body Composition in Healthy Subjects: A Randomized Controlled Trial."
Complementary Therapies in Medicine, 39, 88-94.
Results: In this double-blind, placebo-controlled trial with healthy subjects, those receiving ashwagandha exhibited significant increases in muscle mass and improvements in body composition measured by dual-energy X-ray absorptiometry (DEXA). Strength improvements were noted in both bench press and squat exercises, indicating that ashwagandha may have anabolic effects. The authors suggested these effects could be related to increased testosterone levels and enhanced muscle protein synthesis.
7. Lopresti AL, Drummond PD (2017)
"A Randomized, Placebo-Controlled Trial of the Effects of Ashwagandha on Stress and Anxiety in Adults."
Journal of Alternative and Complementary Medicine, 23(11), 883-890.
Results: This study evaluated the effects of ashwagandha on stress and anxiety levels, which can affect physical performance. Participants taking ashwagandha reported reduced stress and anxiety levels, as well as improved physical performance and less fatigue during physical activities. This suggests that by alleviating stress, ashwagandha may indirectly enhance muscle function and endurance.
8. Ziegenfuss TN, Kedia AW, Sandrock JE, Raub BJ, Kerksick CM, Lopez HL (2018)
"Effects of an aqueous extract of Withania somnifera on strength training adaptations and recovery: the STAR trial."
Journal of the International Society of Sports Nutrition, 15, 46.
Results: This trial investigated the impact of an aqueous extract of ashwagandha on strength training adaptations in healthy adults. The results indicated that participants consuming ashwagandha had greater improvements in muscle strength and size compared to those on a placebo. Enhanced recovery post-exercise was also reported, with lower markers of muscle damage found in the ashwagandha group, reinforcing its efficacy as a beneficial supplement for athletes.

Journal of Nutrition & Intermediary Metabolism, 37, 30-36.
Results: This randomized controlled trial assessed the effects of ashwagandha on muscle strength and recovery following a resistance training program. The study found that ashwagandha supplementation led to a greater increase in muscle strength and significant reductions in perceived muscle soreness and recovery time when compared to a placebo. The participants reported feeling more energetic and less fatigued after workouts, indicating enhanced recovery capabilities.
Conclusion
The cumulative evidence from these studies suggests that ashwagandha supplementation can positively influence muscle function, strength, recovery, and overall athletic performance. Regular use may lead to enhanced muscle strength, improved recovery times, and better endurance capabilities.
For individuals looking to improve physical performance or recover more effectively from exercise, ashwagandha could serve as a beneficial component of their nutritional regimen.
