- We flag Fragrance allergens (if scented variant) and Bacterial overgrowth from prolonged wear on the Natracare and not on the U by Kotex.

- The gap is 40 points, wide enough that this is not a close call, and the Natracare is the one to buy.
- We are less certain about the U by Kotex grade, at 35% confidence against 100%, because it discloses less.
