How Flaxseed Helps with Hot Flashes
Flaxseed lignans are phytoestrogens that weakly bind to estrogen receptors, providing a mild estrogenic effect that can reduce hot flash frequency in postmenopausal women.
🔬 What the Research Says
A 2015 meta-analysis in the Journal of Obstetrics and Gynaecology found flaxseed supplementation reduced hot flash frequency and intensity in menopausal women, though effects were modest.

📋 How to Use
Add 2 tablespoons ground flaxseed to food daily - in smoothies, yogurt, oatmeal, or salads. Must be ground for the lignans to be bioavailable.
💊 Recommended Dosage
2-3 tablespoons (about 40g) ground flaxseed daily.
⚠️ Side Effects & Cautions
May cause bloating initially. Take medications separately from flaxseed.
