Ashwagandha (Withania somnifera) is a root adaptogen with a substantial body of research behind it. Used in Ayurvedic medicine for over 3 000 years, it is now one of the most studied botanicals in modern wellness science. Here is what the evidence says about how it works in the body.

What Makes Ashwagandha Effective?
The active compounds in ashwagandha are called withanolides, a group of naturally occurring steroidal lactones found primarily in the root. These compounds are responsible for many of its measurable physiological effects, from cortisol regulation to cellular protection.
What Ashwagandha Does in the Body
Lowers Cortisol Levels
Multiple randomised controlled trials have demonstrated that ashwagandha supplementation significantly reduces serum cortisol, the body's primary stress hormone. Lower cortisol supports better sleep quality, helps reduce anxiety, and assists with improved metabolic function.
Supports Adrenal and Energy Function
Ashwagandha helps regulate the hypothalamic-pituitary-adrenal (HPA) axis, which governs how your body responds to stress and manages energy output. This makes it particularly useful for people experiencing burnout or persistent fatigue.
Improves Hormonal Markers
Research studies show ashwagandha may increase testosterone levels in men and support thyroid hormone regulation in both men and women. It has also been shown to improve reproductive health markers in men with fertility concerns.
Reduces Inflammation
Ashwagandha has measurable anti-inflammatory and antioxidant activity. It inhibits inflammatory pathways and reduces markers such as C-reactive protein (CRP), which is associated with chronic disease risk.
Enhances Cognitive Performance
Peer-reviewed studies have linked ashwagandha supplementation to improvements in memory, reaction time, and executive function. These effects are partly attributed to reduced neuroinflammation and oxidative stress in the brain.
Recommended Dosage
Research consistently supports a dose of 300 to 600 mg of a standardised root extract daily, taken with food. Effects are cumulative. Most clinical trials measure outcomes at the 8-week mark, which is a realistic timeframe to assess results.
Frequently Asked Questions
Is Ashwagandha safe for long-term use?
Current evidence supports daily use for up to three months, with ongoing safety observed in longer studies. Consult a healthcare professional if you are on chronic medication or have a pre-existing condition.
How long before Ashwagandha produces results?
Most users report noticeable changes within two to four weeks. The full benefit is typically measured at six to eight weeks of consistent use.
Can Ashwagandha help with stress and anxiety?
Yes. Multiple trials show it reduces cortisol and self-reported stress scores significantly compared to placebo.
What are the side effects of Ashwagandha?
High doses may cause mild gastrointestinal discomfort in some individuals. Taking it with food and starting at a lower dose generally prevents this.
Who should avoid Ashwagandha?
It is not recommended during pregnancy or for individuals with autoimmune conditions, hyperthyroidism, or those on immunosuppressant or thyroid medication without medical supervision.
Can I take Ashwagandha with other supplements or medications?
Ashwagandha is generally well-tolerated alongside most dietary supplements. However, it may interact with sedatives, thyroid medications, and immunosuppressants. Always consult your healthcare provider before combining it with prescription medication.
Does FoodGrown’s Ashwagandha use a standardised extract?
Yes. FoodGrown uses a root extract standardised for withanolide content, which is the active compound responsible for ashwagandha’s clinically studied effects. You can view the full product details at www.foodgrown.co.za.
Is ashwagandha suitable for women?
Yes. Research supports Ashwagandha use in women for stress reduction, thyroid support, and energy regulation. It is not recommended during pregnancy or breastfeeding but is otherwise considered safe and beneficial for adult women.
Should I take Ashwagandha in the morning or at night?
Timing is flexible. Some users prefer taking it in the morning with breakfast for energy and focus support throughout the day. Others take it in the evening to support cortisol reduction and sleep quality. Both approaches are used in clinical research. Taking it consistently at the same time each day matters more than the specific timing.
Always speak to your healthcare provider before starting any new supplement, particularly if you are pregnant, breastfeeding, or on chronic medication.
