Can You Take L-Theanine and Ashwagandha Together?
You might not find literal “chill pills” in the supplement section at your local health store, but you will find supplements that can help support your nervous system and encourage feelings of relaxation. While there are more of these than you might think, L-theanine and ashwagandha are some of the most popular.
For some people, a dose of L-theanine and a good night’s sleep might be enough to calm their racing thoughts. However, other people might need the works: A couple supplements for relaxation, a bath, a cup of chamomile tea, a chill book, and soft lights.
If you’re reading this article, chances are, you identify with the latter. Hey, no shame here! In this article, we’ll discuss whether you can combine L-theanine and ashwagandha and how else you can help your nervous system calm down after a stressful day (or week!).
What Is L-Theanine?
Found naturally in green and black tea leaves, this amino acid is known for promoting feelings of calm and focus without knocking you out like a sleepy-time tea. It works by supporting your body’s production of GABA, serotonin, and dopamine. These neurotransmitters can all help you feel less stressed and help you pay attention. Plus, it can also support a good night’s sleep.
The past part is that it doesn’t sedate you — it just dials down the noise a little bit. That’s why it's a popular supplement for people who want to be calm and productive.
What Is Ashwagandha?
Ashwagandha is the ancient Ayurvedic remedy that’s having a modern-day wellness renaissance. This adaptogenic herb can help your body handle stress by supporting health levels of cortisol, the infamous stress hormone.
Studies show it can help improve sleep, ease anxiety, and maybe even boost your memory and mood. Used for thousands of years in Indian medicine, this supplement is now headlining supplement shelves everywhere.
Can You Take L-Theanine and Ashwagandha Together?
So, can you take L-Theanine and ashwagandha together? The short answer is yes.
These two supplements work in complementary ways. L-Theanine can help calm the mind fast, while ashwagandha builds long-term resilience to stress. It's like pairing a spa day with a self-help book.
No major interactions have been reported between the two, and the combo can support focus, mood, and sleep quality when used mindfully. But remember: Just because these supplements are natural doesn’t mean you should wing it. Always start low, go slow, and check with your primary care doctor if you’re unsure.
What To Think About
Although ashwagandha and L-theanine can work well together, there are still some things to consider in order to maximize your benefits. These include dosages of each, the forms of the vitamins, and the quality of your chosen supplements.
Dosages
When it comes to L-theanine and ashwagandha, more isn’t always better — it’s about finding your sweet spot. Most studies use 100 to 200 mg of L-theanine, especially for focus or anxiety relief. For ashwagandha, the typical clinical range is 300 to 600 mg daily of a root extract standardized to at least 5% withanolides.
Basically, that means you should look for quality, not quantity. And yes, you can take them together, but try them solo first to see how your body reacts. As always, talk to a healthcare provider if you’re mixing supplements or managing other health conditions.
Forms
L-theanine and ashwagandha are everywhere these days. You can find them in capsules, powders, gummies, drinks, and even coffee. That might sound crazy, but it’s true — our Mushroom Coffee+ contains a nootropic blend that includes L-theanine, lion’s mane and chaga mushrooms, and coffee extract. It has everything you love about coffee without the jittery side effects.
L-theanine is often derived from green tea or made synthetically, but both forms work the same in the brain. Ashwagandha comes in root powder or extract form. KSM-66 or Sensoril branded versions are the most tested forms of ashwagandha supplement.
The best form for you depends on how you like to supplement. Whether you’re a smoothie blender, capsule popper, or mushroom coffee aficionado, there’s a supplement out there for you.
Quality
Not all supplements are created equal. Look for products that are third-party tested, which helps make sure what’s on the label is what’s in the bottle. For instance, our mushroom blends are all third-party tested for beta-glucans, heavy metals, allergens, mycotoxins and mold. Plus, we use only the best ingredients, because we’d never give you a supplement we wouldn’t take ourselves.
For ashwagandha, check for root-only extracts (not leaves) and a guaranteed withanolide percentage. Bonus points if the brand is transparent about sourcing, manufacturing, and testing.
Who Shouldn’t Combine L-Theanine and Ashwagandha?
Even the dream team has its off days. L-theanine is generally well-tolerated, but in rare cases, it may cause headaches or dizziness — usually if you go overboard on the dose. Ashwagandha can occasionally cause an upset stomach, drowsiness, or in larger doses, lower blood pressure too much.
This combo is also not for everyone. Pregnant or breastfeeding folks, or those with autoimmune conditions, should get the green light from their doctor before adding either supplement to their health stack.
And remember, supplements can interact with meds — especially for thyroid, blood sugar, or anxiety — so ask your healthcare provider before taking anything new. Be smart and sip safely.
How Else Can You Support Stress Management?
Supplements like L-theanine and ashwagandha are awesome tools, but they’re not the whole toolbox. If you're looking to level up your stress relief routine, there's a whole wellness arsenal to choose from.
Here are some tried-and-true options:
- Exercise: Movement (even brisk walking) reduces cortisol and boosts endorphins.
- Meditation and Breathwork: These are science-backed ways to slow your heart rate and calm your nervous system.
- Sleep Hygiene: Consistent sleep schedules + limiting blue light = better rest.
- Therapy or Counseling: Talking it out works. For real.
- Limit Caffeine and Alcohol: Too much of either can mess with mood and sleep.
- Adaptogen Alternatives: Rhodiola, holy basil, or lemon balm are also worth exploring.
No one-size-fits-all fix here. Combining habits and supplements is often the sweet spot. So if you're serious about stress-proofing your life, think of this as your starter pack — not the final formula.
The Bottom Line
Taking L-theanine and ashwagandha together is totally doable and possibly the power couple you didn’t know you needed. As long as you stick with quality sources and smart dosages, this duo can help support mood, focus, and sleep.
Just remember, no supplement replaces sleep, hydration, or decent boundaries. So stay chill, stay curious, and supplement smart. To learn more about how you can support your wellness from the inside out, visit the Everyday Dose blog today.
