Mood & Stress Sleep

What differentiates Zenroot?

In a rapidly growing ashwagandha marketplace, product integrity and botanical authenticity matter. Increased demand has led to quality concerns in the category, including the use of leaf material or other practices intended to elevate withanolide content. Zenroot addresses these challenges with a low-dose, root-only ashwagandha extract which has been standardized by a USP method. Zenroot (Withania somnifera) is clinically studied to support occasional feelings of anxiety and stress, mood, and sleep quality at just 125 mg daily.*1
  • Clinically studied low-dose efficacy at 125 mg¹
  • Root-only ashwagandha extract derived exclusively from the root of Withania somnifera
  • Standardized to 1.5% total withanolides using a USP-validated HPLC method for batch-to-batch consistency
  • Produced under strong quality assurance standards through supply qualification and identity testing
  • Manufactured in BRC (GFSI) and cGMP certified facilities
  • Use of green solvent extraction process utilizing water and ethanol
  • Vegetarian, kosher, and halal certified

Science Overview

Ashwagandha has been widely studied for its potential role in supporting mood , stress support, and sleep quality but usually, efficacy comes at high doses. Zenroot has been clinically shown to support these benefits in a low efficacious dose designed to meet the needs of modern wellness formulations.*1

In a randomized, double-blind, placebo-controlled clinical study, daily supplementation with 125 mg of Zenroot demonstrated improvements across several key markers related to stress, mood, and sleep quality in healthy adults.*1

Stress support

Clinical results demonstrated that supplementation with Zenroot helped reduce occasional feelings of stress compared to placebo.*1

Support for occasional anxiety

Zenroot supplementation was shown to help decrease occasional feelings of anxiety while supporting a more balanced emotional state.*1

Mood support

Participants receiving Zenroot demonstrated improvements in measures associated with a more consistent and positive mood.*1

Sleep quality

Clinical findings also showed improvements in overall sleep quality among individuals supplementing with Zenroot.*1

Technology

Conventional ashwagandha extracts often require higher inclusion levels and can present formulation challenges related to dispersibility and organoleptic performance. Zenroot addresses these limitations through the integration of the Ultrasol nutrient delivery system. Ultrasol spray-drying technology converts the extract into a stable, free-flowing, water-dispersible powder, improving stability, dispersibility, and sensory performance while supporting clinically studied benefits at a low daily dose. The result is a modern, formulation-ready ashwagandha ingredient designed for seamless incorporation into capsules, tablets, gummies, and ready-to-mix beverage systems.

What does this mean for your formulation?

Low-dose efficacy = formulation flexibility

Clinically studied performance at just 125 mg allows developers to incorporate Zenroot into a wide range of formats while leaving room for complementary actives while supporting convenient, consumer-friendly serving sizes.

Root-only extract = authentic botanical positioning

Using exclusively ashwagandha root preserves the traditional botanical profile associated with ashwagandha while supporting strong product differentiation in a category where ingredient integrity and authenticity increasingly influence consumer purchasing decisions.

Standardized phytochemical profile = consistent performance

Standardized using a USP-validated HPLC method which controls withanolide composition, Zenroot supports reliable formulation outcomes and batch-to-batch consistency, helping brands deliver the same trusted experience consumers expect from every bottle.

Improved sensory performance and application range

Enhanced stability and dispersibility enable seamless incorporation into capsules, tablets, gummies, stick packs, powders, and beverage systems without compromising product quality or taste.

Zenroot brings together root-only authenticity, clinically studied low-dose efficacy, and advanced formulation technology to help brands deliver trusted ashwagandha products that stand out in an increasingly crowded marketplace.

Root-only integrity

Unlike some extracts that incorporate leaf material to increase withanolide content or reduce cost, Zenroot is derived exclusively from the root. Leaf-derived extracts can produce a different withanolide profile than traditional root preparations and may introduce variability that creates quality and regulatory challenges in certain markets. Using root-only material preserves the traditional botanical composition historically associated with ashwagandha while supporting a more consistent and well-characterized ingredient profile.

Zenroot is standardized to 1.5% total withanolides using a USP-validated HPLC method, ensuring batch-to-batch consistency and reliability. Its optimized withanolide profile includes both glycosides (such as withanoside IV and V/VI) and aglycones (including withanolide A, withanolide B, withaferin-A, and 12-deoxywithastramonolide) maintained within a defined ratio. That means the extract delivers a balanced spectrum of naturally occurring bioactive compounds found in ashwagandha root, helping support consistent performance and reliable formulation outcomes.
