Glossary terms, category guides, and original research
Which non-toxic tampons are actually free of lead, arsenic, and PFAS? R3 ranks them on published lab testing, not the organic label. No sponsors.
Tampon wear time is how long a tampon stays in before changing. The rule that prevents toxic shock syndrome is simple: change every 4 to 8 hours and never leave a tampon in longer than 8 hours, including overnight.
Tampon absorbency is an FDA-standardized rating of how much fluid a tampon holds, labeled Light, Regular, Super, and Super Plus. Using the lowest absorbency that handles your flow is the single most important step to lower toxic shock syndrome risk.
