The best supplements for women's health change with life stage. Folic acid before and in early pregnancy prevents neural tube defects. Iron matters for heavy periods and pregnancy. After menopause, enough calcium and vitamin D supports bone health. Beyond these, most women eating a varied diet don't need a long list of supplements.
