L-theanine and ashwagandha are quite complimentary in terms of their benefits, but the mechanisms of action are quite different. Ashwagandha works more on a hormonal level, especially with cortisol. L-theanine works more on the neurotransmitters.
L-theanine acts within 30-60 minutes, while Ashwagandha takes time (up to a week) to feel the benefits. This creates a bridge effect where daily doses of L-theanine bridge the longer-term benefits of Ashwagandha.
Yes, you can take l-theanine and ashwagandha together. These supplements do not have any known negative interactions when taken together. In fact, these herbs may be a good combination to help increase sleep quality at night and stimulate cognitive function during the day.

Ashwagandha is perhaps best known for its stress-relieving properties. Several studies highlight this advantage, observing ashwagandha's ability to decrease participants' stress and anxiety levels significantly.
Studies show that ashwagandha can boost endurance during physical activity by sharpening brain function and reducing bodily pain. Due to its positive, calming, energizing effects on the brain and its ability to lower stress hormones, it's helped improve concentration, motivation and stamina in conducted studies.
Unlike many other supplements and medications, ashwagandha's benefits are not immediate. It can take days to weeks before you begin to notice its effects.
There are no confirmed or direct side effects of consuming L-theanine. Generally speaking, it's safe to drink teas and take supplements that contain L-theanine. But it's important to note that the Food and Drug Administration (FDA) doesn't regulate supplement.
There have been no interactions with vitamins, minerals, probiotics, essential fatty acids, and most other supplements. It is perfectly fine to take ashwagandha with melatonin at bedtime to help you sleep. It is also acceptable to use other stress-reducing supplements such as L-theanine and GABA with ashwagandha.
They could interact with sedatives, blood thinners, thyroid supplements, drugs that suppress the immune system, and drugs for anxiety, high blood pressure, and diabetes. Ashwagandha might also interact with supplements that cause sleepiness, like St. John's wort, kava, valerian, and others.
L-theanine Dosage and Use
L-theanine is one of my most common treatments for anxiousness and may help any of the three sub-types. It's usually taken in doses from 50-100 mg once or twice daily. In more severe cases, it may be taken 3 or 4 times per day. It is not habit forming like many anti-anxiety medications.
As long as you follow the L-theanine supplement's dosage suggestions, you can safely take L-theanine daily. And because L-theanine is a 100% drug-free, non-habit-forming ingredient, it is generally considered safe for long-term use.
When taken by mouth: L-theanine is possibly safe when used short-term. Doses of up to 900 mg daily have been safely used for 8 weeks. It isn't clear if L-theanine is safe to use for longer periods of time. It might cause mild side effects, such as headache or sleepiness.
L-theanine is a naturally occurring, non-protein amino acid found in tea that promotes relaxation by reducing stress and anxiety levels. Although L-theanine is not a sedative and does not cause drowsiness, it may help improve sleep quality by promoting a more relaxed state.
Is L-theanine safe for long-term use? Yes. L-theanine is a safe and natural amino acid that can be taken long-term without any adverse effects.
A study on the effects of theanine on the liver showed that when it was administered to mice prior to ethanol exposure, it fully restored the mice's baseline liver functions. These results bode well for drinkers, since they imply that theanine can help prevent ethanol-induced liver injury.
Conclusion: Our study suggests that chronic (8-week) l-theanine administration is safe and has multiple beneficial effects on depressive symptoms, anxiety, sleep disturbance and cognitive impairments in patients with MDD.
54 They found that all the components suppressed weight gain. Green tea powder, catechins, and theanine also reduced triglyceride levels. The researchers concluded that not only can caffeine help prevent weight gain and fat accumulation, but theanine can, too.
l-theanine (γ-glutamylethylamide), an amino acid in green tea, has been shown to affect brain functions by relieving stress disorders, improving mood, and maintaining normal sleep.
In a randomized controlled trial in patients with mild cognitive impairment, L-theanine taken with green tea extract for 16 weeks had no significant effect on memory and attention, though a trend for an improvement in memory was seen midway through the trial [1].
Ashwagandha, for example, may increase thyroid hormone levels, which could cause fatigue, anxiety, shortness of breath and other problems.
If you're feeling more calm and relaxed, that's a good sign that the ashwagandha is working. You may also notice an improvement in your sleep quality. If you're sleeping better and feeling more rested, that's another sign that the ashwagandha is doing its job.
Studies on ashwagandha have used dosages of 250–600 mg/day of a root extract. The most common dosing protocol is 600 mg/day divided into two doses, with one taken in the morning with breakfast and the other in the evening.
The root of Ashwagandha is regarded as tonic, aphrodisiac, narcotic, diuretic, anthelmintic, astringent, thermogenic and stimulant.
