What does dairy-free mean on a supplement label?
Dairy-free means a product is made without milk or ingredients from milk, such as whey, casein or milk powder. Milk is one of the 14 allergens that must be emphasised within the ingredients list of pre-packed food, for example in bold, italic or coloured type.
The same government advice says a product labelled "free-from milk" is a guarantee that it will not contain milk, that "may contain" labels are voluntary, and that you should never assume a vegan product is safe if you have an allergy. If you think you have a milk allergy, the NHS says to see a GP and not to cut foods out of your diet without speaking to one.
Is lactose-free the same as dairy-free?
No. Lactose is the sugar in milk, and a lactose-free or low-lactose product can still contain milk proteins such as whey. The NHS says a food intolerance is different from having a food allergy, and that a food allergy can be life threatening, so with a milk allergy you need a product that contains no milk at all.
What dairy-free protein powders are there?
The dairy-free protein powders in this collection use plant proteins, beef protein or egg white protein instead of whey or casein. Protein per scoop and price vary widely between them, so compare the cost per 25g of protein.
How to compare value (example figures, not real products): a £28 tub of 1kg plant protein with 21g of protein per 30g scoop contains 700g of protein, £1.00 per 25g. A £35 tub of 1kg beef protein with 27g per 30g scoop contains 900g of protein, about 97p per 25g, so the more expensive tub works out slightly cheaper per 25g of protein.
"The amount of protein on the front of the packaging doesn't always tell you which product offers the best value," says Andy Arshad, who runs SupplementHQ. Our guide to reading a supplement label explains where to find the figures.
