How it all began – Rupert’s CFS Story

My very first job was working for a London bank in the late 1980s. As it was my first, I was initially keen and interested. However, as the weeks turned into months it felt like every cell in my body was starting to protest. I ignored this growing unease, dragging myself to the office with diminishing enthusiasm and energy, until one day I woke up and, quite simply, could not get out of bed. I had developed the kind of deep muscle fatigue one would expect to experience after running a marathon – except mine was not relieved by rest. It became my permanent state.

What is CFS?

In time, I was diagnosed with Chronic Fatigue Syndrome (CFS) also known as Myalgic Encephalomyelitis (ME). This is a devastating multi-system disease that is characterized by a range of neurological problems, muscle pain with intense physical and mental exhaustion, relapses, and a range of cognitive problems. According to conventional medicine, the cause of the illness is unknown and so there is no accepted medical treatment or cure.

My Remedy for CFS

In desperation, I turned to complementary therapies where I found many answers, not least the importance of good nutrition. By changing my diet and using a mix of vitaminsmineralsherbs and essential fatty acids, I experienced a significant boost in energy. I was hooked and started exploring other complementary therapies in my long journey of overcoming CFS.
The result of my experience was that I discovered that the gift of lifelong energy is a multi-faceted phenomenon requiring physical, emotional, mental and spiritual balance. In addition to a wholesome diet this means getting sufficient exercise and sleep, making time for play and relaxation activities, developing good social connections, practicing mindfulness and finding meaning in your life. This is the best way to address all forms of both mental and physical fatigue and stress.

The Birth of McNab’s

I wanted to help other people overcome their tiredness so that they, too, could live their fullest life ever. With this in mind, in 2000 I started McNab’s, a conscious brand providing natural energy products, including our bestselling McNab’s SuperCharge Energy Tabs which contain the very same nutrients that helped me overcome my chronic fatigue all those years ago.
Some of our tools to help everyone live a Big Life include our Daily Motivational Quotes and our Health & Wellness Blog.

Our Ethos

At McNab’s, we understand that sustainable living is the best way to create long-lasting positive physical and mental energy. We believe energy is a multifaceted phenomenon that comes not only from the food we eat and the way we look after our bodies, but also from the environments we live and work in, the people we associate with, and the thoughts we think.

We Love Our Planet

Robert Swan, a famous polar explorer, and environmentalist said, The greatest threat to our planet is the belief that someone else will save it.

We challenge Swan’s belief by showing our business does not have to pursue profit at the expense of people and the planet and rely on someone else to fix their mess.

We have shown, over and over again, that putting the planet and people first will benefit all

In 2009 we built the award-winning Energy Works. As South Africa’s first truly green office building The Energy Works is almost entirely self-sufficient, relying on solar power and collected rainwater. We are therefore immune to rolling blackouts and putting a strain on Johannesburg’s exhausted electricity grid.

We hope to inspire business, government, and civil society to follow our lead so that all sectors of society work together towards addressing climate change and our increasingly poisoned planet. After all, we all share the same planet, breathe the same air, and want our children to have a future that is worth saving.
