The Position
This is not another pink supplement brand.
Women have spent long enough choosing between aggressive bodybuilding products and softly packaged wellness powders that underestimate them.
Fortevity is being created for women who take their strength seriously.
- No macho theatre.
- No shrinking language.
- No decorative ingredients.
- No overnight-transformation promises.
Just purposeful performance nutrition, developed with scientific rigour and designed to become part of a consistent strength practice.
The Founding Two
Two products. Built with intent.
In development
Fortevity Re-Build Pro
Build. Restore. Thrive.
A premium whey protein being developed to make high-quality protein easier to use consistently, after training and throughout the day. Created for women who want to support training, recovery and long-term strength without compromising on taste, quality or credibility.

Fortevity Pre-Workout

A considered pre-workout being developed for women who want to arrive at training ready to work. Purposeful ingredients. Transparent formulation. No performative aggression required.
Explore the Pre-WorkoutWhy Fortevity
Four principles behind everything we make.
01
Strength
Physical strength supports a bigger life. Training is not punishment. It is preparation for everything you still want your body to do.
02
Science
Every ingredient should earn its place. We intend to explain what is included, why it is included and how it should be used.
03
Longevity
Not built around a temporary transformation. Built for the next workout, the next decade and the life beyond that.
04
Respect
Women don't need products that patronise them. They need intelligent products, honest information and the freedom to define strength for themselves.
Built by a protein scientist
Fortevity was founded by Dr Aminata Kanu.
A protein biochemist and the founder of RESSETT LAB. After years working at the intersection of protein, muscle, metabolic health and women's healthy ageing, she saw a persistent gap: performance-nutrition brands rarely spoke to women as serious lifelong participants in strength.
Fortevity is being created to close that gap.
Developed with the scientific thinking behind RESSETT LAB. Built as a distinct performance-nutrition brand for the future.

The first products have not yet entered production.
That is deliberate.
Before finalising flavours, formats and formulations, we want to hear from the women who may actually use them. You will not simply be watching a new supplement company launch. You will help us make better decisions before it does.
