Our Story

Built from the Core.

We are FUNCTNL. We believe real performance & longevity starts from the core. The gut is the epicentre and everything else follows.

Function for Purpose

We create clean, science-backed supplements that power digestion, immunity, energy, performance & well-being.

Our philosophy is rooted in the fundamental drivers of longevity: how you fuel your body, move daily, recover deeply, manage stress, and use all your functions to support your system.

Once you master the art of functional living, you can live with strength, balance, and intention. With transparency and purpose at our core, we exist to help you take control of your health and #OWNYOURCORE.

The Journey

Five years of building different.

2014 - 2018
Chronic back-pain
Zohaib, the founder is back and forth to chiropractors & hospitals looking for a quick fix to what then seemed an impossible cycle to get out of.
2018
Met Zainali, a systems based approach Sports Injury Specialist
On the first assessment, Zainali identified the root cause of my pain was due to a 'leaky gut'. He coached me on my lifestyle habits and worked on supplementation to repair the gut lining. I stopped taking protein shakes that day.
5 months later...
Stronger than ever...
I finally healed from the chronic back-pain and started to understand my body as a system. What worked and what didnt. In the gym 4-5 times a week and stronger than ever.
2020
ActiHealth was born
Decided to launch a range of supplements for different areas of health that focus on the gut. Products sold in over 7 countries. But the passion was always in performance...
2026
FUNCTNL. Is Born
ActiHealth rebrands to FUNCTNL. Not a reformulation. A declaration. Gut-First Performance. Own Your Core becomes the north star.
2026
The Performer Launches
Creatine, electrolytes, and liposomal beetroot in one sachet. The product that defines what FUNCTNL stands for. Clean, nitrate fuelled performance which supports the gut.
