Testing strategies for successful brands

By Abby Vorster

All nutraceutical products and dietary supplements promote the goal of keeping people strong and healthy. Their quality and purity are paramount to achieving this goal, making raw material testing and validation central to every brand’s success.

Quality consciousness is growing in the South African nutraceutical and dietary supplements market. Due to the chemical and biological components used in these products, more brand owners have come to recognise the value of quality assurance through testing and validation methods.

Microbiological testing is one of the methods used to ensure the quality and safety of finished products. According to Hersol, this form of testing plays an important role in the production of nutraceutical products and dietary supplements and is essential for consumer safety. Furthermore, as the South African Health Products Regulatory Authority (SAHPRA) views the dietary supplement industry in a similar light as the orthodox pharmaceutical industry, it is essential all products meet the same safety standards of ‘unerringly safe for human consumption’.

Unique technology in the market

Microbiological testing of nutraceuticals and dietary supplements typically consists of monitoring levels of spoilage organisms, as well as ensuring that no food-borne pathogens such as Salmonella are present in finished products. Hersol uses microbiological testing to ensure that all raw materials used in production comply with quality requirements stipulated by the regulator in the government guidelines.

Hersol is also one of a handful of manufacturers that uses latest automated technology for its microbiological testing. This automated technology is based on the rapid detection of several metabolic processes, which takes place within a growing organism. By implementing this form of rapid detection, the manufacturer has been able to simplify test procedures and receives accurate results within hours (instead of days), ultimately speeding up time to market for customers.

Tailored solutions based on individual needs

While testing may appear costly, it is miniscule compared to the cost of a finished product recall.

As a contract manufacturer, Hersol is raw materials laboratory blessed to have a deep customer base in nutraceuticals and dietary supplements. Hersol has been manufacturing products for some of the biggest brand names on the market for more than four decades. Over the years, this has allowed the company to build its knowledge in testing and validation methods, putting the company in an ideal position to advise each customer on what makes biological and economic sense for their brand.

Hersol’s fully equipped raw materials laboratory, which complies with GMP, GLP and SAHPRA guidelines, has undergone a significant upgrade and is now home to various modern equipment. For spectroscopy, the laboratory uses a UV-VIS spectrophotometer, atomic absorption spectrophotometer, infra-red spectrophotometer and the handheld nano Raman, all of which support the manufacturer’s move to increased efficiencies and faster turnaround times in line with market demands. For chromatography, testing is carried out on several high-tech HPLC, GC, and TLC systems. All these analytical techniques are used to test (ID/and assay) all raw materials received from suppliers prior to being released for production.

While testing may seem enormously complex to a brand owner, partnering with Hersol removes this complexity from your quality requirements to ensure your finished products are safe for their intended use.
