Ashwagandha (Withania somnifera) has one of the strongest clinical evidence bases of any adaptogenic herb, with hundreds of human trials. It is a key ingredient in Glowming Choco, the Glowming flavour formulated specifically for evening stress relief, sweet craving management support, and overnight recovery.
What Is Ashwagandha?
Ashwagandha is a small shrub native to India, North Africa, and the Mediterranean. Its root extract, standardised for withanolide content (the primary bioactive compounds), has been used in Ayurvedic medicine for over 3,000 years as a Rasayana (rejuvenating tonic). In contemporary research, it is classified as an adaptogen: a substance that helps the body resist physical, chemical, and psychological stressors by modulating the hypothalamic-pituitary-adrenal (HPA) axis, the body's central stress response system.
What Does Ashwagandha Actually Do?
Cortisol Reduction
Cortisol is the body's primary stress hormone, produced by the adrenal glands in response to perceived threats. Chronic psychological stress, which is endemic in modern urban South African life, maintains cortisol at persistently elevated levels. Chronically high cortisol drives fat storage (particularly visceral/abdominal fat), disrupts sleep architecture, impairs immune function, and is directly linked to carbohydrate and sugar cravings.
A 2019 double-blind randomised controlled trial published in Medicine found that 240mg/day of Ashwagandha root extract over 60 days produced a 23% reduction in serum cortisol compared to placebo, alongside significant reductions in perceived stress scores (PSS) and Food Cravings Questionnaire scores. This is the most direct evidence for Ashwagandha's relevance to stress-related eating.
Sleep Quality Improvement
A 2020 randomised controlled trial published in PLOS ONE found that Ashwagandha root extract (300mg twice daily) over 10 weeks significantly improved sleep quality onset latency (time to fall asleep), sleep efficiency, total sleep time, and sleep quality scores compared to placebo in adults with insomnia. The effect was mediated by Ashwagandha's cortisol-lowering and GABA-modulating actions.
improved sleep quality directly supports weight management, poor sleep disrupts leptin and ghrelin (the hormones regulating appetite), increasing hunger and caloric intake the following day. Ashwagandha's sleep improvement therefore has downstream weight management benefits beyond its direct cortisol effects.
Mental Focus and Cognitive Function
A 2017 study published in the Journal of Dietary Supplements found that Ashwagandha supplementation (300mg twice daily) over 8 weeks significantly improved reaction time, cognitive task performance, and attention compared to placebo. The cognitive benefits are attributed to Ashwagandha's neuroprotective withanolides and its reduction of stress-induced cognitive impairment.
Physical Performance and Recovery
Ashwagandha has demonstrated significant effects on muscle strength and recovery in exercise research. A 2015 study in the Journal of the International Society of Sports Nutrition found that 300mg twice daily over 8 weeks produced significantly greater increases in muscle strength (bench press and leg extension) and greater reductions in exercise-induced muscle damage markers compared to placebo in resistance-trained men.
Ashwagandha and Stress-Related Eating in South Africa
Stress-related eating is one of the most significant contributors to weight gain in South Africa's urban population. A 2023 Discovery Health survey found that 64% of South African adults reported eating more during periods of high stress, with chocolate and sweet foods the most commonly craved items. Cortisol drives these cravings, elevated cortisol increases appetite for high-calorie, high-sugar foods as a primitive energy-seeking response.
Glowming Choco addresses this directly: Ashwagandha may help manage stress (the root cause of cravings), Cocoa Powder satisfies the chocolate craving biologically (theobromine for mood support), Garcinia Cambogia may help manage appetite, and the zero-sugar Stevia formula means the craving is satisfied without breaking dietary goals.
Ashwagandha in Glowming Choco
“I was sceptical about the stress and sleep claims but three weeks in and I am genuinely sleeping through the night. The chocolate flavour at night is something I actually look forward to.”

Frequently Asked Questions
How long does Ashwagandha take to help manage stress?
Most clinical research uses 8–12 week supplementation periods, with measurable cortisol reductions observed from 4 weeks onward. The 2019 Medicine study observed significant stress score improvements at 30 days, with more pronounced effects at 60 days. Consistent nightly use in Glowming Choco is designed to deliver cumulative cortisol-reduction benefits.
Can Ashwagandha support weight management?
Indirectly, yes, through two mechanisms. First, cortisol reduction may help manage stress-driven cravings for high-calorie foods, supporting dietary adherence. Second, improved sleep quality from Ashwagandha normalises leptin and ghrelin, reducing the appetite dysregulation caused by poor sleep. It is not a direct fat-burning ingredient but addresses two major behavioural drivers of weight gain.
Is Ashwagandha safe for daily use?
Ashwagandha has an excellent safety profile across multiple long-term trials. Rare cases of liver enzyme elevation have been reported with very high doses or adulterated products. At standard supplemental doses in certified products, it is well-tolerated in healthy adults. Not recommended during pregnancy. Consult a healthcare professional if you are on medications for thyroid conditions, immunosuppressants, or sedatives. Consult a healthcare professional before use.
When is the best time to take Ashwagandha?
For stress and sleep benefits, evening use is most effective, allowing Ashwagandha's cortisol-lowering effects to work during the evening wind-down period and overnight recovery window. Glowming Choco is designed specifically as an evening ritual for this reason.
