Supplements to Calm Anxiety at Night: Safe Options to Help You Sleep
Struggling with anxiety at night is common. Your mind races, your body stays tense, and sleep feels out of reach. While therapy and lifestyle changes are the foundation for long-term relief, certain supplements to calm anxiety at night can help you relax and fall asleep more easily when used wisely.
This guide walks through the most researched supplements, how they may help, safe dosing ranges, and what to check before trying them. I’ll also link to helpful meditation and therapy resources so you can combine tools for the best results.
How Supplements Help Night time Anxiety
Many supplements act on the brain and nervous system to promote calm. Some increase levels of calming neurotransmitters like GABA, some support balanced stress hormones, and others improve sleep quality so your body can recover.
Remember: supplements are supportive tools — not replacements for therapy or medication when those are needed. If you have a diagnosed anxiety disorder, speak to your clinician before starting anything new.
Best Supplements to Calm Anxiety at Night
Below are supplements commonly used to reduce anxiety at night. Each section includes a short explanation, typical dosing, and safety notes.
1. Magnesium (Magnesium Glycinate or Magnesium L-Threonate)
Why it helps: Magnesium supports nervous system balance and muscle relaxation. Studies show it can reduce anxiety symptoms and improve sleep quality.
Typical dose: 200–400 mg in the evening.
Notes: Magnesium glycinate is gentle on the stomach and good for sleep. Start with a lower dose to test tolerance. Avoid high doses if you have kidney problems. (Source: NIH review).
2. L-Theanine
Why it helps: L-theanine is an amino acid found in green tea that promotes relaxed alertness and may reduce anxious thoughts without drowsiness.
Typical dose: 100–200 mg before bed (or earlier in evening if sensitive).
Notes: Often combined with magnesium for sleep. Well tolerated with few side effects. (Source: PubMed review).
3. GABA (Gamma-Aminobutyric Acid)
Why it helps: GABA is the brain’s main calming neurotransmitter. Some people find GABA supplements reduce bedtime anxiety and promote relaxation.
Typical dose: 250–500 mg taken at night.
Notes: There is debate about how well oral GABA crosses the blood–brain barrier, but many users report benefit. Start small and monitor effects.
4. 5-HTP (5-Hydroxytryptophan)
Why it helps: 5-HTP supports serotonin production, which can improve mood and sleep. It may help nighttime worry when insomnia is tied to low mood.
Typical dose: 50–100 mg at night.
Notes: Do not combine 5-HTP with SSRIs or other serotonergic medications unless supervised by a doctor due to serotonin syndrome risk. (Source: NLM overview).
5. Melatonin (Low Dose)
Why it helps: Melatonin regulates the sleep–wake cycle and can help reset sleep timing. It’s helpful for falling asleep when anxiety delays sleep onset.
Typical dose: 0.3–1 mg (low dose) about 30–60 minutes before bed. Some use 1–3 mg; lower doses often work better for sleep initiation.
Notes: Use short-term or as directed. Long-term effects at higher doses are not well studied. Melatonin may be more of a sleep-timer than an anxiety treatment, but better sleep reduces nighttime worry. (Source: Melatonin review).
6. Passionflower (Passiflora incarnata)
Why it helps: Traditionally used for anxiety and insomnia; some studies show it reduces anxiety and improves sleep quality.
Typical dose: 250–500 mg extract or a cup of tea 30–60 minutes before bed.
Notes: May interact with sedatives; use cautiously if taking sleep medications.
7. Valerian Root
Why it helps: Valerian is commonly used for sleep and may reduce nighttime nervous tension.
Typical dose: 300–600 mg of extract before bed (or herbal tea).
Notes: Some people find it effective; others notice little change. Avoid regular high doses without guidance.
8. Ashwagandha (Withania somnifera)
Why it helps: An adaptogen that helps the body manage stress. Studies suggest it reduces anxiety and improves sleep quality.
Typical dose: 300–600 mg of a standardized extract, usually taken in the evening or split doses.
Notes: Generally well tolerated, but check interactions (e.g., thyroid or sedative medications).
How to Use These Supplements Safely
- Check interactions: If you take prescription meds (especially antidepressants, benzodiazepines, or blood thinners), talk with your doctor.
- Start low, go slow: Begin with the lowest effective dose and wait several nights to evaluate effects.
- Avoid polypharmacy: Don’t combine multiple sedating supplements without guidance.
- Quality matters: Choose reputable brands with third-party testing (USP, NSF, or ConsumerLab).
- Track results: Keep a simple sleep/anxiety diary to note improvements or side effects.
Combine Supplements with Meditation & Therapy
Supplements work best alongside behavioral tools. Mindfulness and sleep-focused practices reduce the root causes of nighttime anxiety. Try pairing supplements with:
- Breath awareness meditation to slow heart rate and calm the mind
- CBT skills for managing worry cycles
- education about anxiety so you know what to expect overnight
Combining short evening meditations with a low-dose supplement often leads to quicker, more consistent sleep improvements than either approach alone.

Side Effects and When to Stop
Most supplements are well tolerated, but watch for:
- Daytime drowsiness or grogginess
- Stomach upset or diarrhea (common with magnesium)
- Headaches or vivid dreams (possible with melatonin or 5-HTP)
- Allergic reactions (rare)
If you experience troubling symptoms, stop the supplement and consult your healthcare provider. Also avoid alcohol with sedating supplements.

Conclusion & Next Steps
Trying a well-chosen supplement can make nights calmer while you build lasting tools like therapy, sleep routines, and meditation. If you want a gentle starting plan, consider magnesium glycinate 200 mg plus L-theanine 100 mg in the evening and pair them with a 10-minute breathing or body-scan practice.
Always prioritize safety: check interactions, choose quality brands, and talk to your clinician when in doubt. Better sleep and calmer nights are within reach — one small step at a time.
