# FODMAP Test Substrates – Common Questions

### FODMAP Test Substrates – Common Questions

### ❓ What are the FODMAP test substrates made of?

The FODMAP test substrates are made of **specific sugars** that are naturally found in food. These sugars are used to help assess how your body digests different types of FODMAPs.

### ❓ Are they gluten free?

Yes — the substrates are made only of sugars and **do not contain gluten**. They are safe to use if you have coeliac disease or are following a gluten-free diet.

### ❓ Can I complete these tests if I’m diabetic?

If you have diabetes, it’s very important to consult your healthcare provider before completing a FODMAP challenge. They will be best placed to advise you, as the substrates are sugars and could affect your blood glucose levels.

✨ **Remember:** If you’re ever unsure about whether FODMAP testing is right for you, please check with your healthcare provider first.
