Why this formula

Standardized inputs. Precision dosing.

Ashwagandha is the most-researched adaptogen in herbal medicine. The root extract used here delivers withanolides, the compounds ashwagandha is usually measured by. Paired with L-theanine, an amino acid found in green tea.

Ashwagandha is traditionally used in Ayurveda as a Rasayana (rejuvenative tonic), for memory enhancement, to balance aggravated Vata (nervine), and to relieve general debility. Used in Herbal Medicine as an adaptogen to help increase energy and resistance to stress.

Common questions about this product

What people ask before buying.

More questions live on the FAQ hub →

What if it doesn't agree with me?

If your first bottle isn't the right fit, email info@kashanutrition.com with your order ID. Our 60-day first-order satisfaction policy covers a full refund to your original payment method (3 to 5 business days, depending on your bank).

What's the difference between this and your standalone L-Theanine?

Our standalone L-Theanine is a single-ingredient relaxation supplement at a higher dose (250 mg). Ashwagandha + L-Theanine pairs a lower dose of L-theanine with ashwagandha, traditionally used in Ayurveda as a rejuvenative tonic and used in Herbal Medicine as an adaptogen for energy and resistance to stress.

Is it for adults?

Yes, the licensed dose is for adults 18+.

Can I take it with my medication?

Talk to your healthcare provider first, especially if you take medication for anxiety, depression, allergy or anything with a sedating effect.

Can I stack it with other Kasha supplements?

We always recommend talking to your healthcare provider before combining any supplements. If they give you the green light, introduce one product at a time so you can see how your body responds.

Do you offer larger bottles or subscription?

We offer 60 and 120 capsule bottles. For Subscribe & Save and bulk discounts, visit our Amazon storefront.
