From the girls who've been there 🌸
"I used to cancel plans every single month because of how bad my cramps were. Started taking these two weeks before and honestly it felt like a completely different cycle. My bloating was barely noticeable.
"The week before my period I used to be a completely different person — snapping at everyone, exhausted by 2pm, crying at random stuff. This cycle was genuinely different. My boyfriend noticed before I even told him I'd started taking them."
"My flow has always been really heavy and painful. After my second cycle on these gummies it was noticeably lighter. I didn't even need to take ibuprofen on day two which has literally never happened before.
"I used to look three months pregnant every month for a week. Started these 10 days before my last period and the bloating was almost nothing. I actually went out the first day of my period which I have never done."
"I was so fatigued the week before my period I could barely get through uni. These genuinely changed that — I still feel tired but it's normal tired, not the drag-yourself-out-of-bed kind.
"My friends used to literally track my cycle so they knew when to give me space. I'm not even joking. Two months in and my flatmate said she genuinely forgot I was even on my period. That has never happened in my entire adult life."
"The sleep disruption during my period was something I didn't even realise was PMS related until it stopped happening. Three cycles in and I'm sleeping through. The flow being lighter has also just made everything more manageable.
"I used to avoid mirrors the week before my period because of how puffy I felt everywhere. The water retention was genuinely awful. This last cycle I didn't even think about it once — I just got on with my life and that felt incredible."

Why Sefflon exists
Built from personal frustration.
Perfected through science.
I spent six years studying nutritional biochemistry. I understood hormones better than most. And yet every month, my own cycle completely floored me.
I tried everything — the supplements, the herbal teas, the magnesium. Nothing really worked. So I went back to the clinical literature and spent eighteen months testing combinations of Chasteberry, Dong Quai, Lemon Balm, Saffron and B6 on myself, adjusting doses, tracking every cycle.
"When I finally got the formula right, I went to the gym on day one of my period. I hadn't done that in years."
I shared it with friends who were calling in sick every month. The results were immediate and consistent. That's when Sefflon had to exist.

"The mood difference is unreal. My flatmate said she forgot I was even on my period this cycle. That has literally never happened before in my entire adult life."

"I used to look three months pregnant every month for a week. Started these 10 days before and the bloating was almost nothing. Actually went out on day one of my period which I have never done."
"The fatigue before my period used to be unbearable — barely getting through uni. This cycle I was completely functional the whole week before. The cramps on day one were uncomfortable but nothing like before. Subscribed so I never run out."
"My friends used to literally track my cycle so they knew when to give me space. Two months in and my mood has been completely stable. They noticed before I even told them I'd started something new."

"My boyfriend noticed I wasn't snapping at him the week before my period. He thought I was in a good mood. I was just on Sefflon."
"I was calling in sick every month. Second cycle in and I worked through it completely fine. My manager has no idea why I suddenly stopped having 'stomach issues' every few weeks."

"My cycle feels like mine again."
"I put off buying these for two months because I'd tried so many things before. I genuinely wish I hadn't waited. The strawberry raspberry taste makes it actually enjoyable to take."

Got questions
Everything you need to know
Most girls feel a noticeable difference within the first few days of taking them — the pre-period tension eases, mood feels more stable, and the usual dread just isn't as intense. By the time your period actually arrives, the cramps and bloating are significantly reduced compared to what you're used to.
Your first cycle on Sefflon should already feel like a major improvement. By your second cycle it's usually locked in as your new normal — and you'll know exactly what you were missing before.
PMS symptoms are caused by hormonal changes that happen in the luteal phase — the two weeks before your period starts. By the time cramps and bloating hit, the hormonal shift is already well underway.
Starting 1 week before means Chasteberry, Lemon Balm and Vitamin B6 are already in your system and working before the symptoms have a chance to build. Think of it as getting ahead of your cycle rather than playing catch-up with it.
Yes — don't stop when your period starts. This is actually when Dong Quai and Saffron are doing the most work — easing cramps, relaxing muscle tension and keeping your mood stable during the heaviest days.
2 gummies every day, from 1 week before your period right through until it ends. That's the full window. Stopping early means cutting the formula short exactly when you need it most.
Ibuprofen masks pain after it's already started — it does nothing for bloating, mood, fatigue or flow heaviness, and you're reacting to symptoms rather than preventing them.
Sefflon works upstream. Chasteberry rebalances your hormones before symptoms hit. Dong Quai relaxes uterine muscle tension so cramps are less severe to begin with. Saffron keeps serotonin levels stable so the emotional side of your cycle doesn't derail your week. It's prevention, not pain management.
For many women, yes. Dong Quai helps regulate uterine contractions and supports healthier blood flow, which can reduce the intensity of heavy days. Chasteberry's hormone-balancing effect also plays a role — excess estrogen is one of the drivers of heavy periods, and rebalancing that can lighten flow over time.
Results vary — some women notice a lighter flow from their first cycle, others see it improve more gradually. It's one of the benefits that tends to build the longer you stay consistent.
Yes — Sefflon is made with 100% natural ingredients and is safe to take alongside other supplements and medication. The formula is naturally derived, non-prescription, and suitable for everyday use.
Yes — natural strawberry and raspberry flavor, sugar-coated. They genuinely taste like sweets. Two a day feels like a treat rather than a chore, which is exactly the point — if something is enjoyable to take you actually stay consistent with it.
No chalky aftertaste, no weird herbal bitterness. Just a gummy that happens to be doing a lot of work for your cycle.
Each bottle contains 60 gummies — 30 servings of 2 gummies each. At 2 gummies a day that's a full month's supply.
If you're taking them across the full cycle window (1 week before through to the end of your period), one bottle covers you comfortably. The 2-bottle and 3-bottle bundles work out significantly cheaper per bottle if you're planning to stay consistent.
We offer a 60-day money back guarantee. If you've taken Sefflon consistently and haven't noticed a difference, contact us for a full refund — no lengthy forms, no awkward questions.
We're confident enough in this formula to back it completely. PMS is genuinely disruptive and we'd never want you to feel like you wasted money on something that didn't deliver.
Most PMS supplements are underdosed, use cheap forms of ingredients, or address one symptom while ignoring everything else. A magnesium gummy won't touch your mood. A B6 pill won't ease cramps on its own.
Sefflon combines five ingredients that each target a different part of the PMS mechanism — hormonal imbalance, uterine tension, nervous system response, serotonin production and inflammation — at doses that are actually meaningful. It's built to work as a system, not as a single-ingredient fix.
We'd rather earn your trust through results than ask you to take our word for it — which is exactly why the 60-day guarantee exists.
