L5: Issue Patterns
| Issue | Frequency | Severity | Representative Quotes |
|---|---|---|---|
| softgels_clumped_together | 8/100 (8%) | high | "All the vitamin D gels were stuck together in one big clump-completely unusable. Not returnable-purchase with caution."; "all the softgels arrived stuck together in one solid mass, making them extremely difficult to separate. I had to put the bottle in fridge for 30 minutes, then manually pull a few apart at a time" |
| adverse_reaction_rash | 1/100 (1%) | high | "Started itching and breaking out in a rash on my arms and legs, so had to stop taking them. Same symptoms as taking too much vitamin A, so don't know if the labels got switched at the factory" |
| dosage_too_high_for_elderly | 1/100 (1%) | medium | "These are 2.5 times the recommended dosage for people over 70, and even worse for younger people. And they are softgels so there is no way to break them in half to get a more reasonable dose." |
| bovine_gelatin_not_vegan | 2/100 (2%) | low | "There is absolutely no reason why this product needs bovine gelatin when there are plenty of vegan/vegetarian options available" |
| misleading_kosher_certification | 1/100 (1%) | medium | "The listing says this product is kosher, but it only has a Triangle K certification, which is not accepted in my community. This should have been clearly stated. I now can't use the product and was told I can't return it." |

| sunflower_oil_ingredient_concern | 1/100 (1%) | low | "The ingredients are bad. It contains sunflower oil which is known to be bad. It is really unnecessary to add that." |
| bad_smell | 1/100 (1%) | medium | "Product smells bad" |
