Brain fog isn't a character flaw. It's oestrogen and progesterone withdrawing from the neurological systems that kept you sharp.
The Cognition Stack targets this directly — Show Up rebalances the hormonal foundations of mental clarity, Fuel delivers creatine to your brain cells the same way it delivers energy to your muscles, and Reboot gives your brain the overnight recovery it needs to consolidate memory and reset for the next day.
Simple daily ritual. Profound difference in how you think.

1. Show Up - Hormones in Sync, Energy in Flow

Your daytime brain-boosting formula. Supports mental clarity, focus, motivation and balanced energy, helping you feel sharp and steady through the busiest hours of the day. Perfect for women experiencing midlife fatigue, mood fluctuations or brain fog.

2. Fuel - 100% Pure Creatine Monohydrate

Your strength, energy & recovery essential. Creatine isn’t just for muscles — it supports brain energy metabolism, memory and mental resilience too. Our ultra-fine 200-mesh creatine helps:

- Increase strength
- Improve power output
- Reduce recovery time
- Support sharper cognitive function
- Clean, pure and unflavoured — just one ingredient.

3. Reboot - The Power of 8 Hours, Now in a Bottle

Your night-time reset. Reboot helps calm the mind, relax the body and support the deep, restorative sleep women 40+ often struggle to get. Wake up clear, calm and ready to go — not groggy.

Take TWO tablets of each product daily, with food.

We take Show Up in the morning — it lives by the coffee machine and works just as well.

We take Zipped after lunch — just in time to beat the bloat and dodge the snack drawer.
