Best low-calorie, low-fat protein powder

Grams of protein per serving: 23g per 25g serving

Calories per serving: 92 kcals

Our health team rated the vanilla crème flavour of this protein powder, which they said had a good balance of sweetness and custardy flavour. It advises adding the powder to 150ml water, which meant the shake was a little thin – so you may prefer to mix in with milk if you prefer a thicker shake. It also foams up a lot after shaking, so it's best to let it settle for a while before drinking.
