Does valerian root help with heart palpitations during perimenopause?

Valerian root may offer indirect support for anxiety-driven heart palpitations during perimenopause, but cardiac symptoms always require a medical evaluation first. Any supplement use for palpitations should happen only after a provider has confirmed there is no underlying cardiac condition.

Heart palpitations are common during perimenopause and are usually benign. Fluctuating estrogen levels destabilize the autonomic nervous system, increasing sympathetic (fight-or-flight) activity and reducing the parasympathetic (rest-and-digest) counterbalance. This can cause the heart to beat more forcefully, faster, or with an irregular rhythm that women notice as palpitations. Anxiety and poor sleep, both of which worsen during perimenopause due to declining progesterone and its effects on GABA-A receptor function, further amplify sympathetic nervous system output and increase the frequency of palpitation episodes.

This is where valerian's mechanism becomes relevant. Valerenic acid, valerian's primary active compound, supports GABA-A receptor activity by inhibiting the enzyme that breaks down GABA. GABA is the nervous system's primary calming signal, and supporting it reduces overall sympathetic nervous system activation. A calmer nervous system tends to produce a more stable heart rate and less pronounced palpitation episodes for those whose palpitations are anxiety-related. A study by Andreatini et al. (2002) found that valerenic acid reduced anxiety, and the sleep quality improvement documented in the meta-analysis by Bent et al. (2006) also supports reduced autonomic reactivity over time.

Declining progesterone during perimenopause reduces allopregnanolone, a natural positive modulator of GABA-A receptors. This loss of inhibitory tone makes the nervous system more excitable, which can translate directly into increased sympathetic activation and a greater tendency for palpitations. Valerian may partially compensate by supporting GABA-A signaling through a different binding pathway.

Valerian's effects here would be most relevant for palpitations that occur alongside anxiety, stress, or poor sleep. They would be less relevant for palpitations that occur in a calm state or during physical activity. The research here is indirect because there are no trials of valerian specifically for palpitations.

Studies have generally used standardized extracts in the range of 300 to 600 mg taken before bed. Your healthcare provider can help determine what form and timing may be appropriate for you.

Tracking how your symptoms shift over time, using a tool like PeriPlan, can help you spot patterns, including whether palpitation episodes correlate with poor sleep nights or high-stress periods.

Safety and interactions to know about

Valerian is generally considered safe for short-term use of four to eight weeks. Side effects include drowsiness, headache, and vivid dreams. The most critical drug interaction concern is additive sedation with alcohol, benzodiazepines, opioids, antihistamines, and prescription sleep medications. Very high doses have been associated with rare liver concerns. Do not drive after taking valerian. It is not recommended during pregnancy, and safety in long-term use beyond eight weeks has not been well established. If you take any medications for heart rhythm or blood pressure, discuss valerian with your provider before starting it.

When to talk to your doctor

Heart palpitations should always be evaluated by a healthcare provider before you try to manage them with supplements. Red flags that require urgent assessment include palpitations accompanied by chest pain, shortness of breath, fainting or near-fainting, rapid sustained racing heartbeat, or palpitations that occur during exercise. Even if palpitations prove to be benign and hormone-related, a provider should confirm this before you address them on your own. An EKG and basic cardiac assessment can rule out arrhythmias and other conditions that can feel similar to benign perimenopause palpitations but require different treatment. Do not use valerian as a substitute for cardiac evaluation.
