Sick of protein powder that makes you poop?

Protein powder can make you poop. It can also cause diarrhea. If you are sick of running to the bathroom after drinking a protein shake, do the following: 

1) Choose a protein powder that is dairy-free. Dairy-based protein powders like casein and whey are notorious for causing diarrhea. This is particularly true for people with irritable bowel syndrome (IBS) or lactose intolerance. If your casein whey or protein powder causes diarrhea, you may be lactose intolerant. People with lactose intolerance are unable to fully digest lactose – the sugar in milk – and often experience diarrhea when they consume dairy. Casein and whey proteins are byproducts of cheese and yogurt production, so if they make you poop, switch to a dairy-free alternative

2) Choose a protein powder that is sugar alcohol free. Sugar alcohols (low-calorie sweeteners) are carbohydrates that are partially resistant to digestion. They can have a laxative effect because they draw water into the gut. They are also a FODMAP and can cause diarrhea for people with IBS. Common sugar alcohols include erythritol, sorbitol, and xylitol.

“This egg white protein powder is anti-bloat, anti-blood sugar dips, anti-artificial tasting. Seriously the best protein powder I’ve EVER tried (I’ve tried literally every brand on the US market, all types of protein powder too). The product is amazing, period.” – Elizabeth 

3) Choose a protein powder that is low in insoluble fiber. Some plant protein powders are naturally high in insoluble fiber. Other protein powders, like those intended to help with weight loss, contain added fiber. Insoluble fiber is a natural laxative and adds bulk to the stool. If you eat a lot of it, it will make you poop.  

4) Choose a protein powder that is additive-free. Some food additives, especially thickeners, cause diarrhea for the same reasons that sugar alcohols and insoluble fiber do. Food additives to look out for are carrageenan, guar gum, and xanthan gum. It is worth noting that although food additives are not necessarily bad for you in small quantities, they can add up quickly, especially if you drink a protein shake every day. At higher quantities, food additives can cause side effects.
