The Best Protein Powders for Building Muscle in 2024

This is one of the most commonly asked questions about protein powder. Fleming stresses the importance of having a consistent daily intake of protein. 'Before relying solely on a supplement, try to ensure you're consuming 1.5-2g per kg of bodyweight regularly,' he says. 'This is going to help you much more than just consuming one shake a day, for example.'

'Most powders will come with a scoop providing around 20-30g of protein. For smaller individuals, one scoop with water or milk will be more than sufficient. For larger individuals, 1-2 scoops with water or milk will do fine. Remember that you can lean on milk such as semi-skimmed or soya (plant-based) to help add additional protein to your shake, if it's necessary.'

'You may also experience bloating and constipation.'
