How can I mix a protein shake without lumps?

Use the liquid and powder amounts stated by the manufacturer. Pour liquid into a clean shaker first, add powder and mix thoroughly.

Check that the lid closes properly and the shaker mixing insert is fitted if supplied. Adjust liquid for thickness within the preparation method suitable for the product.

Do not put boiling water in a sealed shaker. Follow the prepared drink use and storage instructions and wash the shaker promptly after use.
