The QUEST range of products includes herbals, probiotics, amino acids, vitamins, minerals and multi-vitamins.

QUEST was one of the first nutritional supplement companies to exclusively use amino acid chelated minerals in all its mineral containing products. Quest takes into account natural synergies and competition between nutrients that naturally exist in the body. Essential vitamins or minerals are always included to ensure a formula will work without compromising the metabolism of other nutrients within the body.

Quest are also licenced by the UK Medicines and Health Regulatory Authority.
