Can You Drink Protein Shakes When Pregnant?
Written by Jordan Morley · Reviewed against NHS foods-to-avoid guidance · Last updated 28 October 2026
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 are 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 their 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.

Common questions
Can I eat protein shakes in the first trimester?
Yes — the 200mg daily caffeine limit applies from the start of pregnancy, including the first trimester.
Is a small amount of protein shakes OK during pregnancy?
Yes — within the 200mg daily limit, protein shakes are considered safe during pregnancy.
I accidentally ate protein shakes while pregnant — what should I do?
Going over 200mg on a single day is not something to panic about — the guidance is about your typical daily intake. Just aim to stay under the limit going forward.
Is cooked protein shakes safe in pregnancy?
The caffeine content isn't changed by heating, so the same 200mg daily limit applies however protein shakes are prepared or used in recipes.
