A low score is not a strike against a product
It means researchers haven't studied that pairing yet. Whey isolate scores low for joint health because almost no one has tested it there, not because it works against your joints. A score reflects the state of the research — not product quality, purity, or nutrition content. Most pairings sit low for the same reason: research funding has concentrated on a handful of well-studied questions, and everything else is simply unexamined.
What the number means
Each score estimates how strong the published human research is between one product and one goal. We weigh study design first (meta-analyses and randomized controlled trials count for more than mechanistic or animal data), then sample size, consistency across studies, and how recent the work is. The score says nothing about quality, safety, purity, or nutrition content.
9–10 Extensively studied: Multiple meta-analyses or systematic reviews of RCTs, pointing the same direction.
7–8 Well studied: Multiple RCTs on this product, or on its immediate class, for this outcome.
4–6 Some research: Human trials exist but are small, short, mixed, or run on a closely related substance.
2–3 Early research only: Mostly mechanistic, animal, or lab evidence. Plausible, not yet established in people.
1 Not yet studied: No meaningful research connects this product to this goal.
Why some goals aren't scored for some product types
Not every goal is a question you can meaningfully ask of every product. Carb powders have nothing to say about hormone support, and a fruit powder has nothing to say about muscle growth. Asking anyway would produce a column of 1s that reads like a verdict rather than an absence. Each product is scored only against the goals its research literature actually addresses. In the grid, those cells are marked as not scored rather than given a number.
What "pending review" means
Some products have been identified and their reasoning written, but the literature review isn't complete. Those carry no citations yet and we don't claim an evidence tier for them — the number shown is a working placeholder, not a finding.
How blends are scored
Some products are single substances and some are blends of several. When a product is a blend, we score the product as a whole and name the component the evidence actually comes from — so a greens blend's gut score is attributed to the greens in it, and a pre-workout's energy score to the caffeine and beta-alanine in it. The research was run on those components, not on our particular formula, and saying so is the difference between a citation and a claim.
Why some products share a score
Products built on the same underlying substance share a score, because that substance is what the studies actually tested. Trials run on standard whey isolate or a specific collagen peptide, not on a branded product. Where a variant has a documented functional difference, such as hydrolysis speeding digestion, we note it in that product's reasoning instead of inventing a separate score.
What "what the research studied" means
That column names the exact form used in the underlying studies: whey protein isolate, hydrolyzed collagen peptides, pea protein isolate. We include it so nothing here reads as a claim that our specific products have been clinically tested. The studies are on the substance. Our products are built from that substance.
About the study links
Where a score links out, that link points to a real, published human study (PubMed, PMC, or the journal's own page) that fed into that score — not a single citation "proving" the claim, but one of the studies actually reviewed. Not every score has a linkable study behind it: many reflect a body of general nutrition research (protein intake and satiety, for example) rather than one paper, and some reflect the informed absence of any research at all. In both of those cases we don't force a link.
Limits
This is a directional guide built from peer-reviewed, PubMed-indexed literature and published meta-analyses. It is not medical advice, and scores will move as new research publishes. We review it periodically rather than treating it as settled.

- CKChristopher K.Verified BuyerRated 5 out of 5 stars2 hours agoGreat product, great value
Ordered this to spot dose before certain meals to mitigate glucose response: working well. Great value for this strategy
- EVEmily V.Verified BuyerRated 5 out of 5 stars1 week agoEasiest way to get in fiber
Some of the best fiber we’ve tried. It does the trick. It is thick when combined with milk but not too bad when it’s water.
- GGGreg G.Verified BuyerRated 5 out of 5 stars3 weeks agoPsyllium Husk Fiber
I love this product. I eat a very carnivore/fruit/high fat only diet and this is a great way for me to make sure I get enough fiber in everyday. Make sure you drink it soon after shaking as it clumps fast!
- ESEdward S.Verified BuyerRated 5 out of 5 stars1 month agoBest Fiber Supp Available!
Definitely best fiber I've found! Keeps me regular and mixes well, doesn't turn into a gloopy mess like some others. Highly recommended!
- TFTheresa F.Verified BuyerRated 4 out of 5 stars1 year agoGood
Exactly what you’d expect. Would not recommend mixing into a smoothie since it gets gloopy very fast
