Clinically Studied Adaptogens for Stress Resilience

Three well-studied ingredients that help regulate the body’s stress response while supporting mood, focus, and sustained mental energy. Ideal for maintaining calm, clear performance during demanding days.

The Adaptogen Stack combines three clinically studied ingredients—Ashwagandha, Rhodiola Rosea, and L-Theanine—to help your body adapt to stress while maintaining calm, focused performance. Together they support a balanced stress response, mental clarity, and steady energy throughout the day.

Supports Stress Resilience
Ashwagandha and Rhodiola help regulate the body’s stress response through the HPA axis, supporting healthy cortisol levels and helping your body adapt to physical and mental stress.

Promotes Calm, Focused Energy
L-Theanine increases alpha brainwave activity and supports neurotransmitters associated with relaxation, helping promote calm alertness without sedation or jitters.

Reduces Mental and Physical Fatigue
Rhodiola Rosea supports mitochondrial energy production and oxygen efficiency, helping reduce fatigue while supporting sustained cognitive and physical performance.

Supports Mood and Cognitive Clarity
Together these ingredients help support memory, attention, emotional balance, and mental resilience—making it easier to stay clear-headed under pressure.

The Adaptogen Stack combines Ashwagandha, Rhodiola Rosea, and L-Theanine—three well-studied ingredients that support the body’s ability to adapt to physical and psychological stress while maintaining cognitive performance. These compounds work through complementary pathways that influence the body’s stress-response system, neurotransmitter activity, and cellular energy production.

Ashwagandha and Rhodiola function as adaptogens, meaning they help regulate the body’s response to stress by supporting the hypothalamic-pituitary-adrenal (HPA) axis, the system responsible for controlling cortisol and other stress hormones. By helping maintain healthy cortisol balance, these ingredients support resilience to both mental and physical stress while reducing fatigue and supporting sustained performance.

L-Theanine supports calm, focused mental states by influencing key neurotransmitters including GABA, serotonin, and dopamine, which play important roles in mood, relaxation, and cognitive function. It also promotes alpha brainwave activity, a neurological state associated with relaxed alertness and improved attention.

Together, these ingredients support stress resilience, cognitive clarity, and balanced energy, helping you maintain focus and emotional stability even during periods of high demand.

The Adaptogen Stack is designed to support daily stress resilience, mental clarity, and calm, focused performance. Each ingredient can be taken at specific times throughout the day to maximize its benefits.

L-Theanine: Take 1 capsule 30–60 minutes before sleep to promote relaxation and support deeper, more restful sleep.

Ashwagandha: Take 1 capsule once or twice daily to support stress resilience, emotional balance, and cognitive performance throughout the day.

Rhodiola Rosea: Take 1 capsule daily with food, ideally earlier in the day, to help reduce fatigue and support sustained mental and physical performance.

For best results, use consistently as part of your daily routine to support long-term stress adaptation and cognitive resilience.

NooGandha® utilizes liposomal delivery technology to enhance the bioavailability of these compounds, ensuring more efficient absorption by the body.


Rhodiola Rosea: Rhodiola Rosea Root Extract (100mg)
Other Ingredients: Rice Flour, Hypromellose (Capsule), Magnesium Stearate, Silica


*Standardized to 3% rosavins and 2% salidrosides, the bioactive compounds shown in clinical research to support stress resilience, energy, and cognitive performance.
  • L-Theanine: Often felt within 30–60 minutes, promoting calm alertness and reduced acute stress.
  • Ashwagandha: Benefits typically build with consistent daily use over several weeks as stress-response systems adapt.
  • Rhodiola Rosea: May support improved focus and reduced fatigue within 1–2 hours of use.


Expected Results:
With consistent use, the Adaptogen Stack helps support a more balanced stress response, improved focus and cognitive clarity, reduced mental fatigue, and a greater sense of calm resilience during demanding work, training, or daily life.
