Basic whey or plant protein shakes are generally considered fine in pregnancy, but check labels — avoid added caffeine, high-dose vitamin A, and untested herbal blends. Ask your midwife if unsure.
Why is protein shakes a concern in pregnancy?
A straightforward protein powder (whey, pea, soy) mixed with milk or water isn't inherently unsafe in pregnancy, and most women can meet protein needs from food alone. The caution is about what else is in the tub: some products add caffeine, herbal stimulants, or high-dose vitamins (including vitamin A as retinol) that aren't appropriate in pregnancy. Choose simple formulations, check the label, and run it past your midwife.
You can also check the calorie content of protein shakes alongside its safety information. Also check medication safety during pregnancy if you're managing any conditions.
The exception
Avoid 'weight loss', 'pre-workout' and heavily fortified formulas during pregnancy.
