Compare, don't crown
We built a comparison workspace for supplements: same category, side-by-side facts, and a triangle that shows tradeoffs—not one number that pretends one bottle is best for everyone.
How we think about products
Behind the scenes we still model three dimensions—each as a percentile-style signal within its category—so the comparison triangle and sorts have a consistent basis. On the site we emphasize tables and numbers you can verify (price, $/serving, actives, pills), not a headline “winner” label.
The three dimensions are:
Bottle price and servings are on every label; we normalize to “how much active you get per dollar” so you can compare fairly within one category (e.g. magnesium vs magnesium, not vs protein powder).
How much of the main active is in each serving—useful when you care about dose strength or fewer pills to hit a target. “More” isn’t always right; it depends on your needs and your clinician’s advice.
Regimens people tolerate matter. We treat fewer pills per serving as simpler for daily use—one capsule vs four tablets is a real tradeoff, not vanity.
On compare pages, the triangle uses relative positions along these three ideas so you can see tradeoffs at a glance. We don’t lead with blended 0–100 indices as the main story— brands, forms, absorption, and your goals vary too much for one number to crown a winner.
Multivitamins: a different problem
For a single active (like vitamin D), comparing mg or IU per serving is straightforward. Multivitamins pack many actives at once—more of everything isn’t automatically better; some minerals can be risky at very high multiples of the daily value. In our data pipeline we treat multis with extra care using a formulation-style check built from two ideas:
Coverage
A measure of completeness. We check for 22 core nutrients at meaningful inputs (>25% DV).
- Full CreditMeaningful dose (>25% DV)
- Half CreditTrace amounts (10-24% DV)
- No CreditMissing essential nutrient
Balance
A safety check. We penalize dangerous megadosing of toxic-prone minerals while allowing safe B-vitamin abundance.
Same category, relative context
Apples to apples
Comparisons only make sense inside one supplement type. Magnesium products are read against other magnesium products; omega-3 against omega-3. We don’t blend unrelated categories into one leaderboard.
That’s why a great deal on vitamin C doesn’t “beat” a fish oil on our site—they’re not in the same comparison set.
What the triangle is (and isn’t)
For geometry, we still map each product into three relative dimensions (value, potency, convenience)within that category. The dot is a shape of tradeoffs, not a quality grade and not medical advice.
We intentionally don’t print blended 0–100 indices on product pages anymore—those felt like a verdict we didn’t want to stand behind. The triangle keeps the intuition: closer to a corner means “more like that emphasis vs peers,” not “better human outcome.”
Practical takeaway
Use the comparison table for hard numbers (price, $/serving, mg per serving, pills). Use the triangle when you want a quick sense of how a bottle leans—cheap per active, strong per dose, or easy to swallow—relative to the other items you’ve added.
A Real Comparison
Let's walk through a real scenario. You're shopping for magnesium and comparing two products:
Budget Magnesium Oxide
Generic Brand
Premium Magnesium Glycinate
Doctor's Choice
Reading the tradeoffs
The budget bottle delivers far more magnesium per dollar: 400mg at $0.15/serving vs 120mg at $0.37/serving—roughly an order of magnitude more magnesium per dollar on paper. (Absorption and form differences are real; we don’t model them here.)
Per serving, the budget product is also higher dose (400mg vs 120mg). If your goal is fewer capsules to hit a target, that matters; if your clinician wants a gentler step-up, the lower dose might be intentional.
The premium option asks for one capsule per serving vs two tablets for the budget line—less to swallow and track. That’s a legitimate reason some people pay more even when the $/mg looks worse.
So Which Is Better?
It depends on what matters to you.
If you want the most magnesium for your money and don't mind taking two pills, the budget option wins handily. If you prioritize ease of use and prefer a gentler form that's easier on your stomach (glycinate is known for better absorption and fewer digestive side effects), the premium option might be worth the extra cost.
Nothing here picks a single “best” bottle—the numbers surface tensions (cost vs dose vs pills) so you can align with your budget, routine, and professional guidance.
Value: cost per active
The question we try to make easy: "How much active ingredient do I get for my money?"
How we derive it
We use cost per unit of active ingredient—for many products, cost per milligram; for vitamin D, cost per 1,000 IU; for probiotics, cost per billion CFU—matched to how that category is usually labeled.
Internally we still place each product on a relative scale within its category so the triangle can show who is cheaper per active vs the other bottles in that category. On the site, you’ll see the underlying numbers in comparison tables; we don’t lead with a single synthetic “value” badge.
Why sticker price lies
A $10 bottle can be worse value than a $30 bottle if the cheaper one has tiny servings or few doses. Normalizing to active per dollar is the apples-to-apples part of what we do.
Potency: amount per serving
The question: "How much active is in each serving?"
What we use
We read active ingredient per serving from the same facts you’d check on a label (mg, IU, CFU, etc., depending on category). A 5,000 IU vitamin D softgel is “higher potency per serving” than a 1,000 IU one in the plain numeric sense.
For the triangle, we again use relative position within the category—not a public rolled-up potency index—so you can see whether a SKU is a light, middle, or heavy dose compared to peers.
When Potency Matters
- →Therapeutic dosing: If your doctor recommended a specific high dose, you want a product that delivers it in as few pills as possible.
- →Correcting deficiency: When you need to build up levels quickly, higher potency means faster results.
- →Fewer pills: A single high-potency capsule beats taking five low-dose tablets to reach the same amount.
A note on "more isn't always better"
High labeled potency isn't a recommendation. Maintenance vs therapeutic targets, interactions, and upper limits are medical questions. We only reflect what the label says per serving.
Convenience: pills per serving
The question: "How much swallowing and counting does this routine take?"
What we count
We use pills, capsules, or softgels per serving as printed—fewer units per dose reads as simpler for most people. Powders and liquids use the closest comparable serving line from the label where we have it.
Why it still matters
The supplement you actually take beats the one you skip. Simple isn’t lazy—it’s often the difference between a habit and a bottle that expires half full.
Examples (illustrative)
One softgel per serving → usually shows as “easier” on the convenience corner vs four tablets.
Multiple doses per day aren’t always captured as extra “pills per serving”; when in doubt, trust the label and your routine, not the graphic alone.
Sorting, not crowning
We removed “one number wins” from the product experience. You’ll still sort lists by facts—for example bottle price, cost per serving, name (A–Z), or fewest pills—because those are transparent columns, not a hidden blend of priorities.
Internally, a weighted blend of value / potency / convenience used to drive default ordering and badges. We’ve stepped back from that in the UI: the triangle carries the “how does this lean vs peers?” idea without printing one blended index on every card.
If you miss “balanced vs value-first” modes
That was another way to collapse tradeoffs into one sort order. The replacement workflow is: pick a sort you trust (price, $/serving, name), add two or three products to compare, then use the table + triangle to see tensions explicitly instead of trusting a black-box rank.
What We Don't Measure
Our comparisons focus on quantifiable label and catalog fields. Here's what we don't try to boil down into a single index:
Bioavailability & Absorption
Some forms of nutrients absorb better than others. Magnesium glycinate absorbs better than magnesium oxide. Methylcobalamin absorbs better than cyanocobalamin. We don't factor this in because absorption rates vary by individual and aren't consistently documented across products.
Third-Party Testing
We don't verify whether products have been independently tested for purity, potency, or contamination. Look for certifications like NSF, USP, or ConsumerLab if this matters to you.
Ingredient Sourcing
Whether ingredients are organic, non-GMO, sustainably sourced, or derived from whole foods versus synthetic sources isn't reflected in our comparisons.
Manufacturing Quality
GMP certification, facility cleanliness, quality control processes, and contamination testing aren't part of our comparison data.
Effectiveness
We measure what's in the bottle, not whether taking that supplement will actually produce the health outcome you're hoping for. That depends on your individual biology, existing nutrient levels, and countless other factors.
Important Notes
Prices Change
We update pricing regularly, but supplement prices fluctuate daily due to sales, stock levels, and market conditions. Always verify the current price before purchasing.
Affiliate Disclosure
When you purchase through our links, we may earn a commission. That does not change the underlying product fields we store (price, servings, label facts) or how we lay out comparisons—affiliate relationships don’t reorder your table to favor a partner SKU.
Data Sources
Product information is sourced from manufacturer labels and retailer listings. While we strive for accuracy, always check the actual product label for the most current formulation and dosing information.
The bottom line
SuppFindr is for comparison, not coronation. Strong numbers on cost per active or dose per serving don’t mean a product is right for your body—form, genetics, meds, and goals still belong to you and your clinician.
Use tables for arithmetic you can check. Use the triangle for a quick sense of tradeoffs. Ignore any lingering “ranking” instinct: if we ever show a sort order, it’s from a column you chose—not a claim that one bottle is universally best.
