NutraFine RS – Iron fortification

The structure of NutraFine® RS iron powder has been carefully sculpted to increase absorption and take-up by the body’s metabolic system. The fineness and surface structure of NutraFine RS means you do not need to use as much powder in premixes to achieve the same beneficial effect as with other elemental iron products.

NutraFine RS represents a elemental iron for food grade enrichment. By refining our iron powder to a morphology and surface shape we have created exciting possibilities for further dramatic improvements.

Today we are confident that NutraFine RS represents the best all-round solution for flour enrichment and fortification. 

Purity and chemistry

The table and chart below highlight chemical purity and the key factor dissolution rate, known to be highly predictive of RBV (Relative Biological Value). NutraFine RS is extremely pure, performing significantly better than the Food Chemical Codex specifications for reduced iron powder.
