About the ingredients

Ashwagandha (Withania somnifera) is a widely studied adaptogenic herb in modern nutritional research. Adaptogens are a class of botanicals studied for their role in helping the body respond to stress. The plant has been used in Ayurvedic tradition for thousands of years and is now backed by a growing body of clinical research on its effects on stress, sleep, and energy.

L-theanine is an amino acid found naturally in tea leaves (Camellia sinensis), and it's been studied for its effects on relaxation and attention.

Together, the two ingredients are well-paired: L-theanine is associated with relaxation, while ashwagandha is traditionally used as an adaptogen, supporting the body over a longer arc of consistent use.

Color is the easiest way to tell you're holding something that grew. Ashwagandha varies a little batch to batch depending on the season and the soil it came from. The dose and potency in every capsule stay consistent.

What it's for

Kasha Nutrition's Ashwagandha & L-Theanine:

  • Helps to temporarily promote relaxation
  • Used in Herbal Medicine as an adaptogen to help increase energy and resistance to stress (e.g. in case of mental and physical fatigue related to stress)
  • As a Rasayana (rejuvenative tonic)
  • As a sleep aid
  • For memory enhancement
  • To balance aggravated Vata (nervine)
  • To relieve general debility, especially during convalescence or old age

Withania somnifera is traditionally used in Ayurveda: In Ayurveda, the traditional medicine system of India, the body is described through three functional energies called doshas. Vata, the one linked to movement and breath, is closely associated with the nervous system. Restorative, rejuvenating formulas are known as Rasayana. The traditional-use claims on this product draw on that long-standing tradition.

How to take it

  • One capsule twice daily, with or without food
  • For steady support through the day: one in the morning, one in the evening
  • For later in the day: one or two capsules in the evening, ideally 30 to 60 minutes before bed

What to expect

Adaptogens like ashwagandha work cumulatively. Most people give it 6 to 8 weeks of consistent daily use before evaluating. Some notice a calming effect from the formula sooner, since L-theanine tends to feel more immediate. The fuller adaptogenic effect builds gradually.

Timing varies from one person to the next, and your healthcare provider can help you decide what's best for your situation.

Before you start

These cautionary statements come with our Health Canada license.

Common questions

What should I expect when the bottle arrives? +

Quick rundown of what we ship and how it gets to you. Every bottle is checked before it leaves us, then double-sealed: clear shrink wrap on the outside, tamper-evident foil under the cap. Amazon takes it from there. We work with Amazon FBA, so they handle our storage and shipping end-to-end. Your bottle will land in either a small box or a padded Amazon mailer, depending on the order. Both are completely normal. If anything looks off when you open it, send us a note and we'll sort it out. Contact info's at the end of this guide.

What if it doesn't agree with me? +

Finding your match of a supplement is the goal, and we know that takes a little trial sometimes. If you get your first bottle and it doesn't sit right with you for any reason, get in touch. We offer a first-order satisfaction policy and we'll refund it.

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 combines a lower dose of L-theanine with ashwagandha, an adaptogen for longer-term stress and sleep support.

Is it for men and women? +

Yes, all adults 18+.

Can I take it with my medication? +

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

Will it make me sleepy? +

Most people feel a gentle calm; a few find it makes them drowsy, especially when first starting. Until you know how you respond, take it when you don't need to drive or operate machinery. Many people actually appreciate that wind-down effect in the evening.

Can I stack it with other Kasha Nutrition supplements? +

We always recommend talking to your healthcare provider before combining any supplements. Every body is different, and your provider knows your personal health history best. If they give you the green light, we suggest introducing one supplement at a time and seeing how your body responds before adding the next.

Larger bottles or subscription? +

We offer two sizes, 60 and 120 capsules (a 1- or 2-month supply). We're always working on expanding our catalogue with new sizes and product lines, so keep an eye out. In the meantime, you can find us on Amazon at our Amazon storefront, where we run ongoing promotions, offer Subscribe & Save, and bulk-purchase discounts at checkout.
