Methods
- The analysis reads the frozen 2026-08-20 products seed file and sorts all 46 SKU records by brand, product name, and slug.
- A field is counted as disclosed only when its structured source value is present; missing values remain missing and are not inferred from marketing copy.
- Price per serving is calculated only when both priceUsd and servingsPerContainer are present and servings are greater than zero.
- Price per gram of label-stated beta-glucan is calculated only when priceUsd, servingsPerContainer, servingSizeMg, and betaGlucanPct are all present and positive.
- Displayed currency summaries are rounded to the nearest cent after calculation; the frozen CSV retains six decimal places for derived values.
Limitations
- Beta-glucan values are label-stated or source-recorded disclosures; this report did not independently laboratory-test products.
- A recorded COA URL, lot, or date describes the structured snapshot only and is not a claim that a document is current, complete, or tied to the retail unit a reader may receive.
- Prices and availability can change after the 2026-08-20 snapshot. Missing fields are not evidence that a product lacks the underlying characteristic.
- Single-record species groups are shown with N=1 for completeness and should not be treated as market-wide estimates.
