Protein powder for women

Protein powder is a convenient way to add protein, which has EFSA-authorised roles in the growth and maintenance of muscle mass and the maintenance of normal bones. For women it comes up most around exercise, perimenopause and the senior years, when holding onto muscle is a focus. Whey is dairy-based; soy and pea blends suit vegans. It is an addition to a varied diet, not a treatment, so check with your GP or pharmacist if unsure.

What it does

Protein is a macronutrient your body uses to build and maintain tissue. The roles permitted under EFSA-authorised health claims are factual and modest:

The claim that protein contributes to a growth in muscle mass.
The claim that protein contributes to the maintenance of muscle mass.
The claim that protein contributes to the maintenance of normal bones.

These are general nutritional roles. A protein powder is a way to top up your intake; it is not a treatment for menopause, weight or any condition, whatever a product's marketing implies.

Who it is for

Most women get enough protein from a varied diet. A powder can help those who train, who struggle to eat enough, or who are working to maintain muscle through perimenopause, menopause and the senior years, when muscle becomes harder to hold onto. If you are pregnant or breastfeeding, check suitability first.

What to look for when buying

Decide on the protein source: whey is dairy-based and widely used; soy, pea and blended plant proteins suit vegans and those avoiding dairy.
Read the label for the grams of protein per serving rather than per 100g, since serving sizes vary between products.
Prefer products with a short ingredient list and a clear UK supplement label; treat heavily flavoured, additive-rich blends with more caution.
Protein powder is a convenience, not a requirement; most women can meet their needs from food. If you are pregnant, breastfeeding or have kidney problems, speak to your GP or pharmacist first.

Frequently asked questions

What does protein do?

EFSA-authorised claims include that protein contributes to a growth in muscle mass, to the maintenance of muscle mass and to the maintenance of normal bones. These are general nutritional roles. Protein powder is a convenient way to add protein, not a treatment for any condition.

Do women need protein powder?

Not necessarily. Most women can meet their protein needs from food such as dairy, eggs, fish, meat, beans and pulses. A powder is a convenience for those who find it hard to get enough, for example active women maintaining muscle. It is an addition to a varied diet, not a replacement for one.

Whey or plant protein, which is better?

Neither is universally better; the choice is mainly dietary. Whey is dairy-based and widely used, while soy, pea and blended plant proteins suit vegans and those avoiding dairy. Compare the grams of protein per serving and choose on source preference and any allergies.

Is protein powder safe in pregnancy?

A balanced diet usually covers protein needs in pregnancy, and not all powders are tested for it. Check a product is suitable and speak to your midwife, GP or pharmacist before adding any supplement during pregnancy or breastfeeding.
