Both whey and plant protein powders can help you reach your daily protein target. The better choice depends on your diet, digestion and budget.
Whey protein
Whey comes from milk. It is a complete protein, meaning it contains all the essential amino acids, and it mixes easily. It is popular because it is widely available and has a mild taste. It is not suitable for vegans or anyone with a milk allergy, and some people with lactose intolerance find certain types hard to digest.
Plant protein
Common plant powders use soy, pea, rice or a blend. Soy is a complete protein on its own. Pea and rice are often combined so that together they cover the amino acids each one lacks. Plant powders suit vegans and people avoiding dairy. Texture can be grainier than whey, and taste varies by brand.
Quick comparison
- Diet: whey is vegetarian but not vegan; plant protein is vegan.
- Allergies: whey contains milk; soy powders contain soy.
- Texture: whey is usually smoother; plant blends can be slightly gritty.
- Protein per scoop: both commonly give around 20 to 25 g, but check each label.
How to decide
- Avoiding dairy or animal products? Choose plant protein.
- Digest milk products well and want a smooth shake? Whey is a good option.
- Compare the price per gram of protein, not the price of the tub.
