Frequently Asked Questions
Continue reading to learn why certain protein powders cause a sensitive stomach.
In my opinion, the best protein powder for sensitive stomachs are plant based protein powders as they pose the least amount of risk of causing an upset stomach. In addition, plant-based protein powders are typically free of artificial ingredients such as sweeteners and colors, as opposed to its counterpart whey protein.
However, if you simply prefer whey protein due to its bioavailability or the taste, opt to go for a whey protein isolate or a hydrolyzed whey protein isolate. If you are lactose intolerant, consuming whey protein isolates are the best protein powders or sensitive stomachs. In addition, try to go for whey protein isolates that also do not contain artificial ingredients or a long ingredient list, as those are also best for sensitive stomachs.
Whichever option you go with, it’s important to understand what upsets your sensitive stomach, then act accordingly. Look for protein powders that are easily digestible, gentle on the stomach, and free from common allergens or irritants. In addition, go for options with a complete amino acid profile, high-quality ingredients, and minimal additives.
By taking these factors into account, you’ll be able to select a protein powder that supports your fitness goals while being gentle on your sensitive stomach.
