There's no single "correct" period product — flow, comfort, budget, and what fits your life all matter more than any ranking. What follows is a straight comparison of the main options: what each one actually costs over a year, what the genuine health considerations are, and where to find well-made, ethically-produced versions of each. Nothing here is designed to talk you out of what already works for you.
Disposable pads & tampons
The most widely used option, and for good reason — familiar, easy to find, and no learning curve. Conventional pads and tampons are usually made with rayon, synthetic fibres and plastic backing or applicators; organic versions swap in certified organic cotton and drop the synthetic fragrance and dyes.
- Cost: Ongoing — a recurring monthly spend that adds up over a lifetime of periods, more so than any reusable option.
- Environment: The biggest downside. Conventional pads and tampons contain plastic and don't biodegrade; even organic-cotton versions are still single-use.
- Health: Tampons carry a genuine, well-established but rare risk of toxic shock syndrome (TSS) — the NHS puts this at a small but real risk, higher in people under 30, and highest when a tampon is left in longer than recommended. Pads carry no TSS risk. Organic, unscented options reduce exposure to added dyes and fragrance for anyone prone to irritation.
- Good ethical picks: TOTM (Cardiff-based, organic cotton, plastic-free packaging) and Natracare (Bristol-based, biodegradable, one of the longest-running organic period brands in the UK).
Menstrual cups
A soft medical-grade silicone (occasionally rubber) cup, worn internally to collect rather than absorb flow, emptied every 8–12 hours. The steepest learning curve of any option, but the one with the strongest long-term cost and waste case — a single cup can genuinely last a decade or more.
- Cost: The best of any option over time — one cup at £20–£30 can replace years of tampons or pads.
- Environment: By far the lowest-waste option when it lasts as long as it's designed to.
- Health: Worth being accurate here rather than repeating the assumption that cups are automatically safer than tampons — one lab study found menstrual cups actually supported slightly more bacterial growth than tampons under test conditions, though real-world TSS cases linked to cups remain rare. The same hygiene rules apply as with tampons: wash hands before insertion, don't exceed the recommended wear time, and sterilise between cycles.
- Good ethical picks: Mooncup — the original UK menstrual cup, London-founded in 2002. Both Mooncup and OrganiCup are also available through Amazon, useful if you'd rather try one without hunting down a smaller retailer first.
Period pants (reusable underwear)
Ordinary-looking underwear with built-in absorbent layers, washed and reused like any other pair. The most convenient reusable option for anyone who doesn't want to insert anything internally, and increasingly good at handling heavier flows.
- Cost: A few pairs (£25–£40 each) typically pay for themselves within a year of not buying disposables.
- Environment: Low-waste, though washing does add its own water and energy cost — still meaningfully better than disposables over a garment's life.
- Health: No internal insertion, so no TSS risk. Worth checking specifically for "PFAS-free" on the label — some earlier period pants used PFAS ("forever chemicals") in their absorbent and leak-proof layers, and it's now something reputable brands test for and state clearly.
- Good ethical picks: WUKA (British, GOTS-certified organic cotton, independently tested PFAS-free), DAME (UK-based, B Corp, organic cotton), and Fluxies (size-inclusive UK sizes 4–30, PFAS-free, organic cotton and Tencel).
Menstrual discs
Similar idea to a cup but shaped to sit higher, at the cervix rather than in the vaginal canal — some people find them more comfortable, and they can typically hold more than a cup or tampon. Available in both reusable silicone and single-use versions.
- Cost & environment: Reusable discs perform similarly to cups; single-use discs lose most of the environmental advantage.
- Health: Same general hygiene principles as cups apply to reusable discs.
- Note: Newer to the UK market than cups or period pants, so there's a smaller range of well-established ethical brands to point to yet — worth watching this space.
A quick way to compare
| Product | Upfront cost | Ongoing cost | Waste | TSS risk |
|---|---|---|---|---|
| Disposable pads | None | Ongoing, adds up | High | None |
| Disposable tampons | None | Ongoing, adds up | High | Small but real |
| Menstrual cup | £20–£30 | Minimal | Very low | Rare, same precautions as tampons |
| Period pants | £100–£150 for a set | Washing only | Low | None |
