It’s not your training. It’s your fuel.

You didn’t get lazy. You didn’t stop showing up. You’re doing the same sessions you’ve done for years and your body has quietly stopped paying you for them — softer in exactly the places you trained hardest. Here’s what nobody told you: women store 70-80% less creatine than men, and creatine is the single most studied supplement there is for holding onto muscle and strength. Every study that built this category was run on men. The supplements were built for them. You’ve been training on an empty tank and calling it a discipline problem.

Your creatine stores drop every decade after 30 — 20s, 30s, 40s (YOU ARE HERE), 50s+. Food alone rarely fills the gap. Illustrative, Smith-Ryan et al. 2021. Check Availability →

You forgot the word for kettle. You’re 41, not 81.

Re-reading the same paragraph four times. Losing the thread halfway through your own sentence. Walking into a room and just standing there. Your GP said stress. Your GP was guessing. Your brain runs on creatine too — phosphocreatine is the fuel your neurons fire on, and when those stores drop, this is exactly what it feels like. In 2025, researchers stopped speculating about it and measured it — in women exactly like you.

2025 randomised controlled trial — perimenopausal and menopausal women taking daily creatine for eight weeks showed more creatine in the brain, faster reaction times and steadier mood.

Every scoop delivers all three, at the doses that actually matter:

Creatine 5g

The full clinical dose. The fuel your muscle and brain cells run on — and women store 70-80% less of it than men.

Collagen 1g

The specific low-molecular-weight collagen dose shown in a 2018 clinical trial to improve skin hydration and elasticity over 12 weeks.

BCAAs 1g

The branched-chain amino acids that support muscle preservation — especially the walking, gardening, carrying kind of everyday strength.

89% felt it inside 30 days. We refund the other 11%.

We asked them, and here is the honest version. 89% felt more energised and motivated after 30 days. 97% said the results were still there at 90 — and that’s the number that actually matters, because you have bought things before that worked for three weeks and then quietly stopped. 4.8 stars from 8,000+ reviews. And if you land in the 11%, you send it back and we refund every penny. No forms. No arguing.

The evidence for a body after 35 — women store 70-80% less creatine than men; a 14-week study found creatine significantly increased lower-body strength and improved sleep quality in perimenopausal women; a 2025 randomised controlled trial found more brain creatine, faster reaction times and steadier mood after 8 weeks. 89% felt more energised after 30 days, 97% said results were still there at 90 days, 4.8 stars from 8,000+ reviews.

Two days wrecked from one class. That’s not fitness. That’s inflammation.

The recovery loop after 35 — one class, one long walk or one heavy day leads to two days of soreness that is inflammation rather than fitness, so you train less, so you hold less of the muscle you built, and round it goes again. More than 70% of women going through perimenopause live somewhere in this loop.

It isn’t a fitness problem and it isn’t your age talking. It’s inflammation — and it’s why the gap between what you put in and what you get back keeps widening. Creatine helps cut post-effort soreness. BCAAs support the overnight repair. Collagen quietly does the joint work. A 14-week study on perimenopausal women found creatine significantly increased lower-body strength — and improved their sleep quality on top of it. Fewer restarts. Less waiting to feel human again.

43,000 UK women. 8,000+ reviews. 4.8 stars.

Every supplement ad you have seen for twenty years was built for a 24-year-old or for a patient. The perimenopause aisle is either clinical or patronising — black cohosh, red clover, hormone blends named after yoga retreats, ninety quid a box, and not one of them made you feel a single thing. JUICi is three ingredients your body genuinely stopped making enough of, at the doses the studies actually used. One scoop. One glass of water. Thirty days to decide — and if you don’t feel it, we refund every penny. Cancel any time, one click.

Try JUICi risk-free. Let your body decide.
