Hot flashes are one of the most common and frustrating symptoms of menopause. Many women search for natural supplements for hot flashes because they want relief without immediately turning to hormone therapy. These sudden waves of heat can interrupt sleep, drain energy, and make everyday life feel harder than it should.
Night sweats and hot flashes don’t just cause discomfort — they often disrupt sleep, waking women multiple times a night.
The good news? Several natural supplements may help reduce the frequency or intensity of hot flashes and night sweats. This guide walks you through the most commonly used options in clear, practical language, so you can make informed, confident choices.
Why Hot Flashes Happen During Menopause
During menopause, estrogen levels fluctuate and gradually decline. These hormonal shifts affect the brain’s temperature control center, making the body more sensitive to small temperature changes. As a result, hot flashes and night sweats — also known as vasomotor symptoms (VMS) — can appear suddenly and repeatedly.
Stress, poor sleep, and nutritional deficiencies may worsen these symptoms, which is why a whole-body approach often works best.
Do Natural Supplements Really Help with Hot Flashes?
Natural supplements don’t work like medication, and they are not instant fixes. However, research and clinical experience suggest that certain herbs, plant compounds, and nutrients can support hormonal balance, nervous system regulation, and temperature control.
Results vary from woman to woman. Some notice improvement within weeks, while others need more time or a different combination.
Best Natural Supplements for Hot Flashes
Black cohosh (Actaea racemosa)
- What it may help: hot flashes, mood changes
- Evidence: one of the most researched menopause herbs1. It is a common component of combined natural supplements for hot flashes and other menopausal symptoms.
- Safety: Generally, well tolerated. Rarely, people report stomach upset or liver issues; stop and seek advice if you notice unusual symptoms.
Red clover (Trifolium pratense)
- What it may help: hot flashes, bone support
- Evidence: mixed; fermented forms2 may be more effective.
- Safety: avoid in hormone-sensitive cancers unless your clinician advises otherwise.

Dong quai (Angelica sinensis)
- What it may help: hot flashes, night sweats (mainly in combinations).
- Evidence: On its own, it has weak evidence4 for hot flashes, being stronger in herbal blends.
- Safety: May thin blood. Avoid with anticoagulants unless your doctor approves.
Licorice root (Glycyrrhiza glabra)

Evening primrose oil (Oenothera biennis)
- What it may help: night sweats
- Evidence: conflicting results6
- Safety: Short-term use is generally safe for most adults.
Wild yam (Dioscorea villosa)
- What it may help: Sold as pills and creams.

Valerian (Valeriana officinalis)
- What it may help: night-time discomfort, relaxation, mild hot flashes.
