First up, we look at how US retail sales of products making antioxidant claims grew a healthy 8.6% to $64.8bn in 2011, but marketers are still struggling to articulate their benefits to consumers.

Oxis International is on a mission to turn L-Ergothioneine – an antioxidant it claims has “unparalleled” benefits – into a household name. The company said that recently that energy drinks and foods, eye health supplements and skin creams are just some of the products likely to emerge from its R&D platform.
