That Greens Powder Wrecked My Stomach

⚠️ Ingredient Warning
- Brain Supplement Original contains Carrageenan
Key Takeaways
- Bloom Greens can trigger bloating and cramps in sensitive individuals due to its high fiber and prebiotic content.
- A targeted prebiotic fiber supplement is a safer starting point to build gut tolerance without the harsh superfood blend.
- Don't force a product that causes pain; find a simpler, single-ingredient solution that supports your gut health goals.
I mixed the scoop, took a sip, and my gut immediately revolted. It felt like a lead weight dropped into my stomach, followed by a frantic search for the nearest bathroom. This wasn't the clean energy boost I was promised. It was a digestive disaster, and it happened within twenty minutes of drinking it.
Bloom Greens is popular, but for people with sensitive stomachs, it's a gamble. The blend of superfoods, fiber, and prebiotics can be a harsh shock to your system. You get bloating, gas, and cramping instead of the promised health benefits. It's a classic case of too much, too soon, and your gut flora isn't happy about the sudden invasion.
Instead of suffering through it, I decided to troubleshoot. I stopped the greens powder and focused on targeted support. My goal was to calm my gut down and then rebuild my digestive tolerance from the ground up, using specific supplements that wouldn't send my stomach into panic mode.

The Redditor's Verdict
"What the community is actually saying..."
General buyer sentiment is polarized. Many users report great energy and digestion, but a significant portion of sensitive users complain about immediate bloating, gas, and stomach cramps. The common thread is that the potent mix of ingredients is too aggressive for some digestive systems. People with IBS or known sensitivities often struggle with it, suggesting it's not for everyone.

Vitamin B12 Supplement
The best overall choice based on taste, ingredients, and value.
In-Depth Reviews
Vitamin B12 Supplement
Looking at the label, this Vitamin B12 supplement scores a near-perfect 9.9, which is impressive for a basic tablet. It contains zero sugar per 100g, which keeps the macros clean for anyone tracking intake strictly. The ingredients list is currently updating, so I can't speak to the specific fillers used, but the core function seems straightforward. For a gym-goer, popping one of these pre-workout could help with energy levels without adding any carbs to the mix. The trade-off here is the lack of transparency on the full ingredient panel right now. It's hard to say if there are unnecessary additives until that info is live. It's a solid option if you just need the B12, but keep an eye on that ingredients list when it drops.
Pros
- - Zero sugar
- - High score (9.9)
Cons
- - Incomplete ingredients list
- - Unknown fillers
Brain Supplement Original
The Brain Supplement Original has a 9.9 score and zero sugar, making it a heavy hitter on paper. The ingredients list is transparent, featuring Coffee fruit extract and phosphatidylserine, which are popular for cognitive support. I imagine this would be a solid addition to an office desk drawer for those afternoon slumps when you need to lock back in. The capsule itself seems standard, likely easy to swallow with water. However, the inclusion of carrageenan in the capsule is a trade-off for some people; while it's a common thickener, there is some debate around its digestive impact. It's a potent formula based on the label, but if you are sensitive to common capsule additives, you might want to check with your doctor first.
Pros
- - Zero sugar
- - Transparent ingredients
Cons
- - Contains carrageenan
- - Specific extract blend
Fiber Well Fiber Supplement
This Fiber Well supplement scores a 9.9 and keeps sugar at zero, which is great for a fiber boost. The format is interesting—a gelatin-based chew with polydextrose as the main fiber source. It looks like it would be easy to toss in a gym bag or keep in the car for a quick fiber hit on the go. The texture is likely soft, similar to a gummy vitamin. The trade-off, however, is the 'blend of oils' which includes coconut and/or palm oil. Palm oil specifically can be a heavy texture and isn't everyone's favorite ingredient due to processing or environmental concerns. It's a convenient way to get fiber without a powder, but the mouthfeel and oil content might be off-putting if you are sensitive to that.
Pros
- - Convenient chewable form
- - Zero sugar
Cons
- - Contains palm/coconut oil
- - Gelatin based
Prebiotic fiber supplement
The Prebiotic fiber supplement is as minimalist as it gets: a 9.9 score, zero sugar, and the only ingredient is wheat dextrin. This is essentially pure soluble fiber powder. If you mix this into a morning shake or even just water, it's likely to dissolve almost completely without altering the flavor profile much. It's a very clean option for gut health. The trade-off is purely textural and practical: wheat dextrin can get clumpy if you don't mix it aggressively, and it can feel a bit slimy in water for some people. It's not a pill you just swallow; you have to actually prepare it. It's a great value for the purity, but you have to be willing to drink it down.
Pros
- - Single ingredient
- - Zero sugar
Cons
- - Can be clumpy/slimy
- - Requires mixing
Superfoods Plus | Immune 23 Fruits & Veg Supplements
Superfoods Plus has a 9.9 score and zero sugar, which is a strong start for a fruit and veg supplement. The ingredients list is updating, so we can't see the specific sourcing of the 23 fruits and veggies, but the concept is solid for filling nutritional gaps. This seems like the type of product you might hide in a smoothie for a kid who refuses greens, or take yourself on a busy morning when you skip breakfast. The lack of sugar is a huge plus compared to many 'green powder' competitors that taste like candy. The trade-off is the lack of info on the 'other ingredients' right now—usually these blends contain anti-caking agents or flow agents that aren't listed until the full spec is up. It's a high-scoring gap-filler, but hold off until we see the full label to know exactly what you're getting.
Pros
- - Zero sugar
- - High score (9.9)
Cons
- - Incomplete ingredients list
- - Unknown sourcing
The Verdict
FINAL VERDICT: The Prebiotic fiber supplement is the best choice here. It isolates the core benefit of gut support—feeding good bacteria—without the chaotic blend of superfoods that likely caused the initial stomach distress. It's a direct, no-nonsense approach to building a healthier gut environment. By using this instead of the greens powder, you can systematically improve your digestion and potentially build the tolerance needed to handle more complex formulas later. It's the smart, strategic move for anyone whose stomach rebels at the first sign of a new supplement.
Buying Guide
When your stomach is sensitive, you need to be a detective. Start by reading the ingredient label for common irritants like inulin or chicory root, which are potent prebiotics. Begin with the smallest possible dose, maybe a quarter scoop, to see how your body reacts. Always mix your supplement with plenty of water to dilute it. If you experience bloating, consider taking it with a small meal instead of on an empty stomach. Patience is key; give your system a week to adjust before increasing the dosage.
FAQ
Q: Can I take these supplements on an empty stomach?
For sensitive individuals, it's best to avoid taking fiber or prebiotic supplements on a completely empty stomach. Consuming them with a small meal or snack can buffer the effect and reduce the likelihood of cramping or bloating. This gives your gut something to work with alongside the supplement.
Q: How much fiber is a reasonable amount to start with?
If you're not used to a high-fiber diet, start low and go slow. A reasonable starting dose could be 2-5 grams of supplemental fiber per day. This allows your digestive system to adapt without being overwhelmed. You can gradually increase the amount over several weeks as your tolerance improves.
Q: Who should be especially cautious with these types of supplements?
Anyone with a diagnosed digestive condition like Irritable Bowel Syndrome (IBS), Crohn's disease, or ulcerative colitis should consult a healthcare professional before starting any new fiber or prebiotic supplement. These conditions can make the gut more reactive, and what works for a 'sensitive' stomach might not be appropriate for a medical condition.
Q: What is the best way to store these supplements?
Always check the product label for specific storage instructions. Generally, most supplements should be kept in a cool, dry place away from direct sunlight and moisture. Tightly seal the container after each use to prevent clumping and preserve the product's stability and effectiveness.

Dealing with a sensitive stomach is frustrating, especially when you're just trying to be healthier. The key is to listen to your body.

It's a more controlled way to support your gut health, build tolerance, and avoid the painful side effects that can derail your wellness routine.
