Reusable Applicator Bundle

Not all "sustainable" period products are what they claim. From GOTS-certified organic cotton to B Corp accountability, here's exactly what to look for — and what to avoid — when choosing clean period care you can actually trust.

Ever had a week where you felt unstoppable - sharp, motivated, social - followed by a week where getting through your to-do list felt like wading through treacle? You're not imagining it, and it's not a mindset issue. It's your hormones doing exactly what they're designed to do. Most of us were never taught this. We were expected to show up at full capacity every single day of the month, with no acknowledgement that our energy, focus and emotional resilience naturally shift across a 21 to 35-day cycle.Understanding those shifts is one of the most useful things you can do for yourself — not to do less, but to work with your body rather than against it. The four hormones shaping how you feel Four key hormones drive the changes you experience across your cycle: oestrogen, testosterone, progesterone, and cortisol. Each has a different job, and each peaks and dips at different points in the month. 1. Oestrogen rises through the follicular phase, bringing with it sharper focus, higher motivation and a generally more optimistic outlook.2. Testosterone peaks around ovulation, adding a layer of confidence, drive and physical capacity. Then comes progesterone in the luteal phase — calming, but also slowing, bringing a need for more rest and recovery. 3. Cortisol, the stress hormone, doesn't follow the cycle in the same way, but chronic stress can disrupt everything else, making it one of the most important things to manage. MENSTRUAL - Days 1–5 Hormones at their lowest. Energy is inward and reflective — the body needs rest and warmth. FOLLICULAR - Days 6–13 Oestrogen rising. Energy builds — great for starting projects, new routines, creative work. OVULATORY - Days 14–20 Oestrogen and testosterone peak. You're at your most social, confident and physically capable. LUTEAL - Days 21–28 Progesterone rises. Energy slows — prioritise sleep, recovery and lighter demands on yourself.   Your symptoms are signals, not weaknesses Fatigue in the second half of your cycle, low mood in the days before your period, disrupted sleep, strong food cravings — these aren't character flaws or failures of willpower. They're predictable hormonal patterns. When you can name what's happening and why, they become something to navigate rather than push against. The same is true for what you put in and on your body. During the menstrual phase, when hormones are at their lowest and your body is most sensitive, the materials in your period care actually matter. Riley's organic cotton tampons, pads, and pantyliners are made from 100% GOTS certified organic cotton — no chlorine bleach, no synthetic fragrance, no pesticides. It's period care designed around hormonal sensitivity, not just convenience.   The long game You don't need to overhaul your life to feel the benefit of working with your cycle. Start by noticing. Track how you feel across a few cycles. Match your high-effort work to your high-energy phases. Protect your rest in the luteal phase. Choose period care that doesn't add to your body's load. Understanding your hormones is the first step. Supporting them is where change actually happens.   Free download: Hormones & Your Cycle — Riley's complete guide A 12-page visual guide covering the four key hormones, all four cycle phases, common symptoms decoded, and how to support yourself at work, in training, and with your period care.

Seed cycling, supplements, 30-day resets — the quick fix promises are everywhere. But your hormones work on a longer timeline than the algorithm suggests. Here's what supporting your hormonal health actually looks like, and why slow and steady is the only real fix.
