Satisfaction Gap Scoring — Cognitive Health
Ingredient-level consumer satisfaction across six formulation-relevant topics — effectiveness, side effects, taste, scent, swallowing, and mixing. Topics that are about the ingredient itself, not the packaging or the price.
Consumer product reviews contain complaints and praise across many dimensions. We isolate six that are directly about the ingredient experience — the things a formulator can actually influence.
Effectiveness
Weight: 40%
Does it work?
Side Effects
Weight: 30%
Does it hurt?
Taste
Weight: 15%
Can you stomach it?
Scent
Weight: 5%
Does it smell?
Swallowing
Weight: 5%
Is the dose format practical?
Mixing
Weight: 5%
Does it dissolve/blend?
Excluded: Packaging (manufacturer's problem), Shipping (retailer's problem), Price (brand's pricing decision), Quality (ambiguous)
Dissatisfaction rates across all six topics for 18 cognitive-health ingredients, sorted by weighted composite score (best to worst). Color coding: ≤10% low · 10–20% moderate · 20–35% elevated · 35–50% high · >50% critical

Four patterns emerge from the data that matter for ingredient selection and formulation strategy.
12–17% for most ingredients. Floor is 5% (Mg Threonate), ceiling is 17% (Huperzine). The ingredients don't really separate on "does it work." Effectiveness is table stakes — the real differentiation happens elsewhere.
Range: 25.9% (DHA) to 40.3% (DMAE). This is the dimension where ingredient selection genuinely matters. A 15-point spread in side-effect dissatisfaction is the widest actionable gap in the dataset.
Choline: 72.7%, Huperzine: 72.2%, Carnitine: 64.9%, Citicoline: 64.7%. These are ingredients where scent alone could drive consumer rejection — an issue that rarely appears in clinical data but dominates real-world experience.
DMAE: 52.9% mixing dissatisfaction. Choline: 46.6%. Bacopa: 34.3% taste. These ingredients may perform significantly better in capsule formats where taste and mixing are bypassed entirely.
ALCAR's satisfaction data from the opportunity brief, placed alongside category-level ranges from the 18-ingredient analysis above.
| Topic | ALCAR | Category Avg | Signal |
|---|---|---|---|
| Effectiveness | 9.4% (n=32) | 12–17% | Well below average — consumers who try it are unusually satisfied |
| Side Effects | 55.6% (n=9) | 30–40% | Above average — but sample too small to be reliable |
| Taste | 0% (n=1) | 15–35% | No signal |
| Scent | 0% (n=1) | 30–65% | No signal |
| Swallowing | 0% (n=1) | 10–22% | No signal |
ALCAR falls below the 200-mention threshold for this analysis. These numbers are from the ALCAR opportunity brief and should be treated as directional, not definitive. The side-effect signal is the primary uncertainty and the clearest pre-launch research priority.
Limitations worth naming before this data informs any decisions.
This tells you what consumers complain about for each ingredient. It does not tell you complaint rates — reviews are a curated "top reviews" sample, not a census of all purchasers.
Within-ingredient topic ratios are directionally reliable. If 40% of Choline's negative mentions are about scent while only 15% are about taste, that ordering likely reflects real consumer experience.
Cross-ingredient volume comparisons reflect sampling depth, not relative failure rates. Lion's Mane having 10,604 topic mentions vs. Magnesium Threonate's 1,122 says more about the product landscape we sampled than about which ingredient gets more complaints per unit sold.
product_topics table — topic-level sentiment (positive, negative, neutral) from consumer product reviews. Dissatisfaction % = negative / (positive + negative). Composite weights: Effectiveness 40%, Side Effects 30%, Taste 15%, Scent 5%, Swallowing 5%, Mixing 5%. Reviews are "top reviews" from product listings — a curated sample. Each row is a (review × topic) pair — a single review can generate multiple topic rows. Products often contain multiple ingredients — dissatisfaction for multi-ingredient products is attributed to all ingredients in the formula.
