How Much Protein Do Women Really Need?

Protein has become a buzzword, but the basics are simple. Here is how much you need, why it matters more with age, and easy ways to get it.

Key takeaways
  • The baseline recommendation is 0.8 g of protein per kilogram of body weight per day.
  • Many experts suggest somewhat more, around 1.0 to 1.2 g/kg, for older adults to help preserve muscle.
  • Spreading protein across meals, rather than saving it for dinner, makes it easier to use.

Protein supplies the building blocks your body uses to maintain muscle, bone, skin and hair, and to make enzymes and hormones. Needs do not drop as we get older; if anything, using protein efficiently gets harder.

The numbers

The official Recommended Dietary Allowance for adults is 0.8 grams per kilogram of body weight a day. For a woman weighing 150 pounds (about 68 kg), that is roughly 55 grams.

That figure is a minimum to prevent deficiency. Many nutrition researchers suggest older adults aim for around 1.0 to 1.2 g/kg a day to help preserve muscle, especially alongside strength training. For the same 150-pound woman, that is roughly 68 to 82 grams.

If you have kidney disease or another condition that affects protein needs, follow your own clinician's advice.

Spread it out

Many women eat little protein at breakfast and lunch and most of it at dinner. Aiming for a solid portion at each meal, something like 25 to 30 grams, is a practical way to reach your total.

Easy ways to get it

Do you need protein powder?

Not necessarily. Food comes first, but a powder can be a convenient top-up if your appetite is small or your days are busy. Check labels for added sugar, and look for products that have been independently tested.
