InfiniFiber (Nootropics Depot) Review 2026: Worth the Price?
Checks out. — Mostly Legit

"LactoSpore probiotic supports digestive comfort"
Bacillus coagulans at 2 billion CFU matches doses used in real IBS and bloating trials.
PubMed: Bacillus coagulans GI symptom trials -
"2.6x more beneficial bacteria than any single fiber tested"
The cited 2025 study tested fiber blends generally, not this specific 12-ingredient product.
Cantu-Jungles et al., Gut Microbes 2025 -
"Apple pectin and chia fiber support digestive regularity"
Apple pectin is dosed at 250mg here; clinical trials use 6,000-15,000mg for measurable effects.

"Formula optimizes SCFA ratios (propionate/butyrate/acetate) for metabolic health"
These exact gram outputs weren't measured in humans taking this product; they read like a formulation model, not a trial result.
Consumer advice
If you want a fiber supplement, this is a decent one - full doses are disclosed per ingredient, which is rare and a real plus. But ignore the mood/brain, longevity, and metabolism-optimization claims; those aren't demonstrated for this specific blend. You could likely get similar gut benefits from a cheaper combination of resistant starch, acacia fiber, and a basic probiotic, or just eating more diverse plant fiber from food. Start with a small dose to check tolerance, since 12g of mixed fiber can cause gas in people not used to it.
Claims vs Evidence
AGGRESSIVE1 of 6 claims supported by evidence. These grades score the marketing, not the product — a claim only counts as supported when the label discloses a dose that matches the studies behind it, so blends that hide doses cap at “partial” no matter how good the formula is.
"supports comfortable regularity"
Supported
Mixed fiber reliably improves stool bulk and regularity in most people.
Based on: Solnul Resistant Potato Starch, Acacia Fiber, Purified Alpha-Cellulose, Oat Hull Fiber
Source: General fiber physiology consensus
"promotes steady daily energy"
Unsupported
No direct evidence fiber/probiotic blends raise daily energy levels.
Based on: LactoSpore, fiber blend
Source: Internal: claim-to-ingredient gap analysis
"supports gut-brain axis, mood, and cognitive clarity"
Stretch
Gut-brain axis exists, but this specific blend has no human mood/cognition data.

"supports longevity and cellular health"
Unsupported
No clinical trials link this product to longevity or cellular aging outcomes.
Based on: fiber blend
Source: Internal: claim-to-ingredient gap analysis

Stretch
SCFA ratios were likely modeled or estimated, not measured in humans taking this product.
