Each product sold at a store is scanned and scored 0 to 100 by CheckIt AI. The scoring system analyzes every ingredient on the label and checks for six categories of concern: harmful chemical additives, seed oils and inflammatory fats, artificial colors and flavors, allergens, high fructose corn syrup and excessive sugars, and preservatives that are banned or restricted in other countries.
The store's overall grade is the average safety score across all products we have analyzed from that retailer. A grade of A means the average product scores 85 or above — indicating clean, safe formulations. A grade of F means the average drops below 35, signaling widespread use of concerning ingredients.
Stores like Whole Foods and Trader Joe's tend to score higher because they enforce stricter ingredient standards and carry more organic and clean-label products. Conventional stores like Walmart and Kroger carry a wider variety, including many products with multiple flagged ingredients. However, every store sells both clean and concerning products — the key is knowing which ones to choose.
