Selected Soy Isoflavones for Hot Flashes - Malaysian Women 2026
Soy isoflavones are the first non-hormonal choice with evidence for moderate hot flashes. The Messina 2016 meta-analysis and follow-up studies show a 20-25% reduction in hot flashes in women who are 'equol producers' (30-50% of women). Because soybeans are plant-based, the halal status is usually easier to verify, but the exact product label still needs checking. It is often considered by women who cannot or do not want hormone therapy, or who want a herbal approach before considering hormone treatment.
