In the second part of this NutraIngredients focus on joint health, we analyse the elbow work
going on in the supply channel.
When it comes to nutraceutical solutions to joint health problems, glucosamine dominates. Chondroitin
sulphate and MSM are popular too along with collagen and ingredients that claim multiple benefits like
maritime pine bark extract and omega-3s.
With constantly emerging science other ingredients move in and out of the space such as botanical
antioxidants like rosehip oil, so a survey such as this is never exhaustive. But we will do our best. One thing
that is clear is that glucosamine – now a $2bn (€1.47bn) global blockbuster – is the daddy. It is most
commonly blended with chondroitin so the two have become linked in the minds of many consumers.
Quality
Talking to suppliers one issue dominates – QUALITY. It would seem the glucosamine/chondroitin market has
gained a fillip of luck in that supplier concerns about contamination, counterfeit and all-round poor quality
material has not translated to widespread consumer anxiety and subsequent category rejection.
While the rate of growth has dipped post- recession along with a natural levelling off as the ingredients have
achieved a kind of mass exposure, demand remains buoyant especially in the US and Japanese supplements
markets, and quality issues largely remain an industry, rather than a concern. Quality assurance standards,
such as Generally Recognised as Safe (GRAS), and National Formulary specifications, can differentiate one
quality ingredient against another inferior ingredient.
Sourcing
Something like 70-80 per cent of global glucosamine supply is sourced from Chinese shellfish, with India and
Vietnam also present. Corn derived glucosamine from the US is gaining market share for vegetarian
glucosamine, with Cargill’s Regenasure® offering coming from that source and being sold at a premium over
the shellfish material.
It is Chinese material that has traditionally raised the most quality control eyebrows, a situation that Larry
Kolb, president of US operations for TSI Health Sciences, observed had not improved much over the years. "Quality is always an issue," he said, noting TSI had dedicated facilities in China to gain total control over
the supply of material. "There is so much fragmentation of supply in China that it is nearly impossible to
ensure standards are met across the sector." The Natural Products Association had begun a program in
China to boost traceability and other quality control measures.
"Specifically, a manufacturer needs to use a robust analytical method that takes into account known EMA
(economically motivated adulteration) contaminants," said Kenn Israel, vice president of marketing at
Californian contract manufacturer, Robinson Pharma. He added that the fact glucosamine was being made to
pharma standards by a lot of suppliers, and classified as a drug in some countries, could, "mandate more
stringent supply chain management".
Low hanging fruit
While still highly niche, the increasing interest of the food and beverages market in glucosamine and
chondroitin, is presenting new formulation challenges for suppliers. "Significant challenges remain in the
dose requirement for results and the solubility, clarity, and robustness of the material to food processing," said Israel. "I think that there is lower hanging fruit in the functional food market (versus supplements)."
