Protein bars are a great source of energy and nutrition, especially for those with busy lifestyles. Unfortunately, they also contain a lot of carbohydrates, including FODMAPs, which are difficult to digest and can trigger irritable bowel syndrome (IBS) symptoms.

12 best low fodmap protein bars

The low-FODMAP diet was developed to allow IBS sufferers to manage their symptoms. It's a challenging diet to design and maintain, as it requires followers to remove FODMAPs from their diet and then slowly reintroduce them and record their body's reactions.  

Although most popular protein bars are high in FODMAPs, some aren't and are safe for IBS sufferers.

Are Protein Bars High in FODMAPs?

A protein bar can contain as much as 43 grams of carbohydrates, of which 24 grams are sugars, and many of those FODMAPs.

So, although they can contain as much as 40% of the recommended protein intake, they may trigger IBS symptoms.

Below are 12 of the best bars for those on a low-FODMAP diet.

1. Orgain Organic Vegan Protein Bars

These protein bars are low in sugar and are made with only 10 grams of organic plant based clean protein (brown rice, pea, chia seeds). They're also gluten-, soy-, and dairy-free.

Each bar contains about 140 calories, 3 grams of organic dietary fiber, and 5 grams of sugar.

2. MariGold Keto Fat Bombs

With less than a gram of sugar per bar, they don’t contain too many FODMAPs but do contain good amounts of fiber, potassium, and magnesium.
