3/5 Evidence Score

Shagandha® is a branded Withania somnifera (ashwagandha) root extract positioned for stress, cortisol balance, and sleep support. Ashwagandha is one of the best-studied adaptogenic herbs, with randomized trials of standardized extracts showing reductions in perceived stress and serum cortisol and improvements in sleep quality. Honest framing: the strongest clinical evidence comes from specific standardized extracts such as KSM-66® and Sensoril®, and Shagandha®'s rationale draws on this broader ashwagandha evidence base rather than its own large trial program. Shagandha® coexists on the site with generic ashwagandha and branded forms including Shoden®, Sensoril®, and ZenRoot®.

Studied Dose Ashwagandha root-extract stress/sleep trials commonly used 300–600 mg/day of standardized extract; Shagandha® is dosed per manufacturer guidance.
Active Compound Withania somnifera root extract standardized to withanolides (commonly ~2.5–5%) — Shagandha®; an adaptogenic extract in the ashwagandha family.

Benefits

Stress and Cortisol Support

Ashwagandha is an adaptogen that helps the body manage stress. Randomized trials of standardized root extracts report meaningful reductions in perceived stress and serum cortisol, the basis for Shagandha®'s positioning for everyday stress resilience.

Sleep Quality Support

Ashwagandha root extract has been associated with improvements in sleep onset, sleep efficiency, and overall sleep quality in controlled trials. This makes it a popular choice for people whose poor sleep is tied to stress and a busy mind.

Calm and Mood Support

By supporting a balanced stress response, ashwagandha may help ease feelings of anxiousness and support a steady mood. Effects are best viewed as supportive of general wellbeing rather than treatment of a clinical condition.

Cognitive and Wellbeing Support

Lower stress and better sleep may translate into improved daytime focus and quality of life. Some ashwagandha trials report cognitive and wellbeing improvements alongside reduced stress.

Adaptogenic Vitality Support

As a traditional Ayurvedic rasayana (rejuvenative), ashwagandha is used to support overall vitality and resilience. Standardized extracts provide a consistent, identity-verified way to obtain withanolides.

Mechanism of action

1

HPA Axis Modulation

Ashwagandha withanolides help modulate the hypothalamic-pituitary-adrenal (HPA) axis, supporting a more balanced cortisol response to stress, which underlies its adaptogenic stress and sleep benefits.

2

GABAergic Activity

Withanolides are reported to enhance GABA-related signaling, promoting calming, inhibitory neurotransmission that may support relaxation and sleep onset.

3

Antioxidant Neuroprotection

Ashwagandha constituents provide antioxidant activity and have been reported to support neuronal health in laboratory models, contributing to its cognitive and wellbeing applications.

Clinical trials

1
Standardized Ashwagandha for Stress and Cortisol

Prospective, randomized, double-blind, placebo-controlled trial of a high-concentration full-spectrum ashwagandha root extract (300 mg twice daily) over 60 days in 64 chronically stressed adults.

64 chronically stressed adults.

Ashwagandha significantly reduced perceived stress scores and serum cortisol versus placebo and was well tolerated. A foundational trial supporting ashwagandha's stress and cortisol benefits that informs Shagandha®'s positioning.

2
Ashwagandha Root Extract for Sleep

Double-blind, randomized, placebo-controlled study of ashwagandha root extract over several weeks evaluating sleep parameters and anxiety in adults, including those with insomnia.

Adults with insomnia and anxiety.

Ashwagandha was associated with significant improvements in sleep onset latency, sleep efficiency, sleep quality scores, and anxiety versus placebo. Supports the sleep-quality benefit attributed to the broader ashwagandha evidence base.
