My ingredient supplier cannot yet give me values for Potassium, Vitamin D and Added Sugars. How do I update my nutrition labels without this information?
You will not be able to update your Nutrition Facts label without this information. However, you may be able to determine the values on your own if your supplier will provide the formula information for the ingredient they sell to you.
The Potassium and Vitamin D calculations are fairly straightforward once you have the formula information from the supplier. In the case of Added Sugars, you may need to work with your supplier to determine which sugars qualify as naturally-occurring and which are added.
