Calculate Your Protein Intake

Protein needs for women follow the same weight-based ranges as men, with a few life stages that call for extra intake. Pregnancy and breastfeeding both raise protein needs to support the baby's growth, while adequate protein after menopause helps offset the natural decline in muscle and bone density.

Life stageRecommended intake
General adult woman1.2 – 1.6 g/kg
Pregnancy+ ~25 g/day above baseline
Breastfeeding+ ~25 g/day above baseline
Post-menopause1.4 – 1.8 g/kg (supports bone & muscle)

General guidance only — pregnant or breastfeeding women should confirm intake with their doctor or midwife.

Quick Reference

  • General health (sedentary): 0.8–1.0 g/kg body weight
  • Weight loss: 1.6–2.2 g/kg to preserve muscle in a deficit
  • Muscle gain: 1.8–2.5 g/kg depending on training experience
  • Athletic performance: 2.0–3.1 g/kg
  • Spread intake across 4–5 meals of 25–40g each for best results
