Anxiety & Stress
Supplements and herbs studied for anxiety, stress response, and related outcomes.
Evidence guide
This guide compares supplements searched for everyday stress, a calmer state, and mental rest. It does not replace professional evaluation: it organizes ashwagandha, L-theanine, and chamomile by evidence, safety, drowsiness, and possible interactions.
How to interpret this category
- Ashwagandha is usually reviewed when the main intent is perceived stress or sustained mental load; extract and dose change the context.
- L-theanine is often considered when people want relaxation without much drowsiness, especially when caffeine is also used.
- Chamomile fits as a gentle herbal option, with more variable evidence and precautions around allergies or sedatives.

Frequently asked questions
Which supplement should I review first for everyday stress?
It depends on context. Ashwagandha is compared more for sustained perceived stress; L-theanine for daytime calm; chamomile as a gentle herbal option. Sleep, caffeine, alcohol, and medications change the decision.
Can I combine ashwagandha, theanine, and chamomile?
Avoid combinations without reviewing drowsiness, sedatives, alcohol, pregnancy, breastfeeding, liver context, thyroid context, and medications. Comparing one option at a time makes tolerability easier to interpret.
When should I seek professional support?
Panic attacks, self-harm thoughts, intense symptoms, persistent insomnia, benzodiazepine or antidepressant use, or functional impairment deserve professional evaluation first.
Can stress be related to sleep or deficiencies?
Yes. Poor sleep, too much caffeine, alcohol, low intake, anemia, or other factors can contribute. That is why habits, labs, and context should be reviewed before choosing supplements.
