Common questions

How do I make one up?

Pour 200-230ml of cold water into a shaker, add the contents of the sachet, and shake until it is fully dissolved. It is ready to drink straight away.

Can I mix it with milk instead of water?

Yes. Skimmed milk or unsweetened soya milk both work and give a creamier result. Mixing with water keeps the meal to the calories shown on the pack.

Does one sachet replace a whole meal?

Yes - one sachet is one meal, so there is nothing to add to it.

Where can I see the full ingredients and nutrition?

The full nutritional breakdown, the ingredient list and the vitamin and mineral content are all in the panels further down this page.

Order before 2:30pm on a weekday and standard delivery is 2 to 5 working days, free over £65. Express is next working day for £4.95. Click and collect at a pick-up shop is also available. These are estimates, not guaranteed dates.
