Look at the food you already eat
Eggs, dairy, fish, beans and soy all provide protein. A varied plant-based diet can supply it too. Look at what you eat across the day, rather than one meal alone.
A shake is another option. Think about where you would use it—at breakfast, in a smoothie or when you don’t have time to prepare food—before buying a tub.

What do the grams on the tub mean?
The scoop’s weight includes every ingredient in the powder. Look for the protein amount on the label; it can be less than the total scoop weight, as the example below shows.
- Protein amount: compare grams of protein, not scoop size.
- Recipe: choose unflavored to add your own flavor, or a flavored powder you can mix as it is.
- Tub size: a large container is a bigger commitment before you know whether you like it.
A made-up label example
30 g of powder → 25 g of protein
The two numbers describe the same serving. This is not a product listing or a personal protein target.

Whey and casein both come from milk
Whey and casein are milk proteins. Neither is an alternative for someone who needs to avoid milk protein because of an allergy. Read the full ingredient information, even when there is no separate Contains statement.
The comparison below explains digestion speed and the common claim that casein is the better bedtime protein.

Is lactose-free the same as milk-free?
Lactose intolerance concerns difficulty digesting lactose, the sugar in milk. Milk allergy involves an immune response to milk proteins. Whey and casein are milk proteins, so a lactose-free claim does not make either milk-free. Read the ingredients and allergen information even when there is no separate Contains statement.
For lactose content, check the exact product’s current manufacturer information rather than assuming an isolate is lactose-free. We haven’t verified lactose amounts for the powders compared on the shortlist.
