The company G&G started as a partnership between David Gaiman and his pharmacist wife, Sheila, in a room of a house in East Grinstead in 1965. Shortly after, the first shop was opened in East Grinstead's historic High Street, supplying health foods along with the vitamins and minerals.

A move was necessary in 1983 to larger premises on Railway Approach. The move meant a turning point for G&G. Rather than compete in the traditional health food market, a new concept was born: the Vitamin Centre. G&G began to concentrate on providing nutritional data and research information from around the world to practitioners, nutritionists and clinics in the UK and Europe. The company quickly established an enviable reputation for the data supplied and for the high quality professional product range, which was developed as a result of its research. In 1987 G&G moved to London Road with 10.000 square feet of space. Within a year, the first encapsulating machine had been purchased and G&G were making their own label vitamins (the Trufil™ range) how they wanted: pure, high quality and high strength.

G&G now supply practitioners, doctors, trade and clinics and direct to the public in the UK, East and West Europe, Russia, Japan, Hong Kong, Africa, USA and Australia. In fact, over 40 countries.

G&G also manufactures and supplies vitamins, minerals, amino acids and proteins for the respected Human Detoxification Programme, currently operating in the former Soviet Union.
