Getting enough protein in your diet is vital for your health – with a whole host of benefits– and out of pure convenience, a lot of people choose to take protein powder as a way to supplement their intake. We’re big fans of the stuff, but there can be some uncomfortable digestive effects if you use one that your body doesn’t agree with. Bloating and gas is common with some protein powders, and can put people off using them altogether. But it doesn’t have to be this way: the problem doesn’t tend to be the protein itself – it’s what else is (or isn’t) in the powder.
In our opinion, the best protein powders are the ones that help you hit your macros, while also supporting your digestion and gut health. So, here’s what to look for when you’re protein powder perusing – and why it matters.

If you’ve never taken protein powders before or are early on into your journey with them, a high protein load can be hard for your gut to break down efficiently – especially at speed.
There are also some common culprits in some protein powders that can leave people bloated or uncomfortable, like lactose, certain artificial sweeteners, or high sugar alcohols. These can ferment in your gut if your body is unable to digest them properly, resulting in gas and bloating.
It can also be caused by the way you consume the shake, as well as the shake itself. Some people will drink protein shakes very fast to get them over and done with, but this can result in swallowing excess air in the process, which can lead to abdominal discomfort.
But luckily, all of these causes can be avoided without having to cut protein powders out completely. Ones formulated with gut health in mind can actively support digestion – and we’re here to help you find them.
To find a protein powder that will help and not hinder your gut health, there are a few things to bear in mind choosing which to buy.
Many people who suffer from post-powder bloating do so as a result of the lactose content in whey protein. Since it is derived from dairy products, whey protein can disagree with people who struggle to digest lactose. If this is the case, try whey isolate. This goes through additional filtration which strips out most of the lactose. And if this still bloats you, plant-based protein like pea or rice might be the move.
If you’re going for straight protein powder, look for a short ingredients list. Of course, when the powder is fortified with other minerals, enzymes and vitamins, that list is bound to be bigger. But whichever you choose, the same rule applies: the fewer artificial sweeteners and sugar alcohols, the better – especially if you know your gut is sensitive
Many protein powders have added gut-supportive nutrients in their formulation, which can help make digestion easier and avoid discomfort. Some worth mentioning are B vitamins (which support energy metabolism and the gut lining), zinc (which supports immunity and gut integrity), and vitamin D (which has been shown in research to regulate the gut microbiome).
If you know you have a sensitive digestive system, thickeners, anti-caking agents and excessive emulsifiers can lead to irritation. Ingredients like xanthan gum are normally fine for the average person, but for sensitive guts, they can cause trapped gas and other discomfort. If you’re worried about this, a simpler formula might be better for you.
You might be wondering if protein powder can actively help your gut health, or if all of this is just to avoid harming it. Well, it’s a bit of both.
A well-formulated protein powder won’t transform your gut overnight if you’re struggling with digestion. However, it can absolutely support better digestion in your day-to-day after consistent use. Adequate protein supports tissue repair across your entire body – and this includes the gut lining. So, if you’re fuelling your body right, chances are your gut will be getting that treatment too.
When it comes to protein powders with added digestive enzymes, it’s a win on both sides. Better digestion equals more protein actually reaching your muscles, so it’s good for performance and gut comfort.
If you’re experiencing digestive discomfort from your protein powder, there are a few things you can do to hopefully alleviate it.
