Most people give up on a fiber supplement within two weeks. Not because fiber doesn't work, but because they picked the wrong one.
Y
ou know you should be eating more fiber. Most of us aren't getting enough. So you grab a tub off the shelf, stir a scoop into water and within a few days you're bloated, gassy and forcing down something that tastes like wet cardboard.
Sound familiar? The problem usually isn't fiber. It's the formula. Here's what to look for before you buy.
What to look for in a fiber supplement
- A blend of fiber types, not just one. Different fibers do different jobs. Some add bulk, some soften, and some (called prebiotic fibers) feed the good bacteria living in your gut. Look for a blend that includes prebiotic fibers such as inulin, resistant starch and partially hydrolyzed guar gum (PHGG). Together they support digestion more broadly than one fiber alone.
- A meaningful dose per serve. Check the nutrition panel, not the front of the tub. A product that delivers 1g of fiber per serve won't move the needle. Aim for around 4g or more per serve, so you close a real chunk of your daily gap without drinking a liter of sludge.
- Gentle on the gut. The whole point is to feel better, not worse. Fibers like PHGG are known for being well tolerated, and a small daily serve you can build up slowly is far easier on your system than a heaped tablespoon of something harsh.
- Something extra for gut balance. The best formulas go beyond fiber. A probiotic alongside prebiotic fiber means you're feeding your gut flora and adding to it at the same time.
- Clean label, low sugar. Many fiber drinks are loaded with sugar or artificial sweeteners. Look for low sugar, natural flavor and a short list of ingredients you recognize. If you avoid dairy, soy or gluten, check for those too.
- It has to taste good. It sounds obvious, but it's the reason most people give up. If it's unpleasant, you won't take it every day, and fiber only works if you're consistent.
The best fiber supplement is the one you'll actually take every day.
Where Pro Gut+ fits
We built Pro Gut+ because we couldn't find a fiber supplement that ticked all six boxes. Here's what's in every 7g serve:
- 4.1g of dietary fiber, 4g of it prebiotic, from green banana resistant starch, organic Jerusalem artichoke inulin and Sunfiber® PHGG
- 1 billion CFU of probiotic Saccharomyces cerevisiae (Boulardii) to help your gut flora balance
- A fermented organic wholefood blend of mung beans, brown rice, red lentils, chickpeas, flaxseed, millet and quinoa
- Just 23 calories and 0.3g of sugar, naturally sweetened with monk fruit
- Free from dairy, soy and gluten
- A delicious natural berry flavor
It helps digestion, helps reduce bloating, promotes bowel regularity and helps decrease constipation. And it's one heaped teaspoon a day.
