Key Takeaways
6. Transparent Labs Vegan Protein Powder
If you're looking for a plant-based protein that's easy on your stomach, Transparent Labs Vegan Protein Powder is a solid contender.

They keep things pretty simple with the ingredients, usually just around 5-7 per serving, and it's free from artificial sweeteners, colors, and preservatives. Plus, it's non-GMO and gluten-free, which is a nice bonus for many.
One thing to note is the sweetener. They use stevia, and while many people are fine with it, some folks can experience digestive upset from it. It's something to be aware of if you've had issues with stevia before. The texture is also a bit different from whey protein; it's not exactly gritty, but you might notice a slight difference in your mouthfeel and a bit more residue in your shaker cup. It mixes well, though, so that's a plus.
Here's a quick look at what you get:
Protein Source: Organic Rice Protein, Organic Pea Protein Isolate
Protein Per Serving: 24 grams
Key Features: Non-GMO, Gluten-Free, Soy-Free, No Artificial Additives

7. Gainful Low-Lactose Protein
Gainful's Low-Lactose Protein is a pretty interesting option if you're trying to cut down on lactose but still want a whey-based supplement. They claim it's 98% lactose-free, which is a good start for many people who find regular whey a bit rough on their stomachs. What sets Gainful apart is their whole customization angle. You don't just pick a flavor; you can actually tailor it to your fitness goals, whether that's weight loss, muscle gain, or just general maintenance. They also offer these flavor boost packs, which is kind of neat. You can add them to an unflavored base, and apparently, you can even mix and match them to create your own unique shake. Some people really like this because it gives them control over the sweetness and flavor intensity.
The unflavored version is pretty straightforward, often just whey protein isolate, a bit of green tea extract or tapioca maltodextrin, and sunflower lecithin. This simplicity is a plus if you're trying to avoid a lot of extra ingredients. However, it's worth noting that the flavor packs themselves do contain sweeteners like stevia, which might not sit well with everyone's digestive system. So, while the base protein might be gentle, the flavor additions could be a different story for some.
Here's a quick look at what you might get:
Feature | Details |
|---|---|
Protein Source | Whey Protein Isolate |
Lactose Content | ~98% Lactose-Free |
Protein Per Serving | Up to 26g (varies by formulation) |
Flavors | Unflavored base with optional flavor packs |
Price Per Serving | $2.55 – $3.50 |
One of the bigger points to consider with Gainful is the subscription model. It's not a one-off purchase, so you're committing to regular deliveries. Also, some users have mentioned that it can be a bit pricier per serving compared to other options out there, and a few have found it can sometimes be a little clumpy when mixing. They also don't seem to have third-party testing, which is something many people look for in supplements.
8. Jacked Factory Authentic ISO
Jacked Factory Authentic ISO is a whey protein isolate that really focuses on keeping things simple and clean. It's made from grass-fed cows, which is a nice touch, and they say it's free from artificial stuff like fillers and dyes. This makes it a good candidate if you're trying to avoid those extra ingredients that can sometimes upset a sensitive stomach.
The macro breakdown is pretty solid here. You get 25 grams of protein per scoop, with just 1 gram of carbs and half a gram of fat, especially in the vanilla flavor. This low carb and fat count makes it a decent choice if you're watching those numbers, like on a keto diet. It's also pretty affordable, coming in at around $1.33 per serving, which is competitive.
However, it's not perfect for everyone. Some people find the sweetness, likely from stevia and possibly sucralose, to be a bit much. Also, a few users mentioned it can leave behind some clumps when mixed, so you might need to shake it a bit longer or use a blender. The flavor can also be hit or miss; while some enjoy it, others find it a bit artificial, especially when mixed with just water. If you're sensitive to sweeteners or gums, you might want to check the ingredient list for the specific flavor you're considering, though they do offer an unflavored option.
9. Nutricost Whey Protein Isolate
When you're looking for a protein powder that won't break the bank but still gets the job done, Nutricost Whey Protein Isolate is a solid contender.

This powder uses whey protein isolate, which generally means it's lower in lactose compared to whey concentrate. That's good news for folks with sensitive stomachs who might react to dairy. It's also gluten-free and non-GMO, and they manufacture it in a facility that follows GMP guidelines. Plus, it gets tested by a third party, which is always a good sign for quality control.
Here’s a quick look at what you get:
Protein Content: Typically around 30 grams per serving, which is a bit more than some other options out there.

Third-Party Tested: This adds an extra layer of confidence in the product's purity and quality.
Value: Often one of the most affordable options per serving, especially when buying larger sizes.
Now, it's not perfect. Some users have mentioned that certain flavors might not mix as smoothly as others, leaving a few clumps behind. It's something to keep in mind if you're really particular about your shake's texture. Also, while the base product is good for lactose sensitivity, if you're strictly dairy-free or vegan, you'll need to look elsewhere. But for a straightforward, affordable whey isolate that many find easy on the stomach, Nutricost is definitely worth considering.
10. Naked Nutrition Egg White Protein Powder
Sometimes, you just need a straightforward protein source without a lot of fuss. That's where Naked Nutrition's Egg White Protein Powder comes in. It’s a pretty simple option, made from just one ingredient: egg whites. This makes it a really clean choice if you're trying to avoid dairy or other common allergens.
It's a good way to get your protein in, especially if you're sensitive to whey or plant-based proteins. Egg white protein is known for being easily digestible, which is a big plus for sensitive stomachs. Plus, it provides a good amount of amino acids to help with muscle recovery after a workout.

Wrapping It Up
So, finding the right protein powder when your stomach gets easily upset isn't as complicated as it might seem. We've looked at a bunch of options, from whey isolates that are super filtered to plant-based choices, all designed to be easier on your gut. Remember, everyone's different, so what works for one person might not work for another. It's really about paying attention to how your body feels after you try something. Don't be afraid to experiment a little, and if you're really unsure, chatting with a doctor or a dietitian can give you some extra peace of mind.

Sometimes, you just need a straightforward protein source without a lot of fuss. That's where Naked Nutrition's Egg White Protein Powder comes in. It’s a pretty simple option, made from just one ingredient: egg whites. This makes it a really clean choice if you're trying to avoid dairy or other common allergens.
It's a good way to get your protein in, especially if you're sensitive to whey or plant-based proteins. Egg white protein is known for being easily digestible, which is a big plus for sensitive stomachs. Plus, it provides a good amount of amino acids to help with muscle recovery after a workout.
Here’s a quick look at what you get:
Protein Source: 100% Egg White Protein
Digestibility: Generally well-tolerated, even for those with dairy sensitivities.
Amino Acid Profile: Offers a complete spectrum of essential amino acids.
Mixability: It mixes pretty well, though some people find it works best in a blender.
Because it's just egg whites, it doesn't have a strong flavor on its own, which is great if you like to add it to different things like smoothies or oatmeal without altering the taste too much. It’s a solid, no-frills protein that’s easy on the gut.
Wrapping It Up
So, finding the right protein powder when your stomach gets easily upset isn't as complicated as it might seem. We've looked at a bunch of options, from whey isolates that are super filtered to plant-based choices, all designed to be easier on your gut. Remember, everyone's different, so what works for one person might not work for another. It's really about paying attention to how your body feels after you try something. Don't be afraid to experiment a little, and if you're really unsure, chatting with a doctor or a dietitian can give you some extra peace of mind. The main thing is to find a protein that helps you reach your fitness goals without causing a whole lot of digestive drama.
Is Casein Protein Lactose Free?
