First, choose a product with a declared lactose content that meets your needs, then pick a fat content and pack size that suit how much milk you drink. A pack of 6 × 1 L can work well if you use milk regularly, have space to store it and can finish each carton within the stated time after opening. If you only drink it occasionally, a smaller size means less milk to use up once opened. Lactose-free milk is still milk, so don’t confuse it with a product that contains no milk proteins.
If the amount of lactose in the milk is a key factor in your choice, compare the information shown for each product. French Health Insurance explains that lactose intolerance affects how lactose is digested, and that tolerance varies from person to person.
For drinks, breakfast or cooking, a pack of 6 × 1 L may suit your routine, as long as you have room to store it and follow the instructions for each carton once opened.
Whether you’re choosing skimmed, semi-skimmed, whole or organic milk, check the specific product: fat content, pack size and storage instructions can vary within the same range.
When choosing lactose-free milk, start by checking its declared lactose content and ingredients. Then choose a pack size you can use within the time stated on the packaging.
| Criteria | What to check | Who is it for? |
|---|---|---|
| Lactose and ingredients | The declared lactose content for the specific product and whether milk appears in the ingredients list. | If I’m mainly keeping track of my lactose intake, I want to be able to check the stated content without confusing “lactose-free” with “milk-free”. Around 50% of consumers prioritise this. |
| Pack size and storage | The volume per carton, storage conditions and how long the milk can be kept once opened. | If I use milk often, I want a convenient pack, but I don’t want to open more than I can finish. Pack size is the top priority for around 30% of consumers. |
| Fat content and range | The fat content per 100 mL and, if you wish, whether your chosen variety is labelled organic. | For drinks or recipes, I want to choose between skimmed, semi-skimmed and whole milk while still opting for a lactose-free product. Around 20% of consumers put this choice of variety first. |
Lactose-free cow’s milk still contains milk proteins. French Health Insurance distinguishes between lactose intolerance and an allergy to milk proteins.
If you have a milk allergy, don’t choose a product based only on the “lactose-free” label. Check the ingredients and the allergen information on the packaging.
A pack of 6 × 1 L contains several cartons, but the storage time starts from the moment each one is opened. Instructions vary by product.
Open one carton at a time and check how long it can be kept chilled. If you don’t drink much milk, consider a 50 cL carton or a single carton.
Any carton you open but don’t finish within the stated time may go to waste.
The Lactel, Candia and Auchan products mentioned here don’t all come in the same pack size, have the same fat content or carry the same instructions for use after opening.
Check the label on the variety you’re buying: lactose content, ingredients, fat per 100 mL, net quantity and storage instructions.
The Matin Léger range includes skimmed, semi-skimmed and organic whole milk varieties. Carrefour lists the UHT skimmed variety in a pack of 6 × 1 L.
Candia says its Candia+ lactose-free milk is available in 1 L, 6 × 1 L, 50 cL and 4 × 50 cL sizes.
Carrefour offers lactose-free semi-skimmed milk in its Classic’ range, including single cartons and packs of 6 × 1 L.
Auchan offers UHT lactose-free milk with 1.2% fat in 1 L cartons and packs of 6 × 1 L.
No. “Lactose-free” doesn’t mean “free from milk proteins”. French Health Insurance distinguishes between lactose intolerance and an allergy to milk proteins. Check the allergen information and ingredients for the product in question.
A pack of 6 × 1 L is better suited to regular milk drinkers, while a 50 cL carton means less to finish once opened. Candia says its Candia+ milk is available in both pack sizes. Whichever you choose, follow the storage instructions for each carton.
Follow the instructions for the product you’ve bought, and chill it as directed. Lactel states that its organic whole milk can be kept for 3 days; Auchan’s product information gives different storage times depending on the product. Don’t assume the instructions for one variety apply to another.
Check the ingredients, milk allergen information, net quantity and nutritional details for your chosen variety. The French Ministry of the Economy reminds food businesses that allergens must be listed and highlighted in the ingredients. The wording on the front of the pack doesn’t replace checking the full label.
