Why is ferritin a fantastic source of dietary iron?
Ferritin is an iron-storage protein found in most living organisms; we call plant ferritin “phytoferritin” and this is highly concentrated within our HiFe peas.
A few years ago, the Balk group collaborated with Prof Sue Fairweather-Tait to investigate the bioavailability of iron in phytoferritin derived from pea seeds. A PhD student, Tony Perfecto used in vitro digestion and intestinal cell culture to demonstrate that not only was pea ferritin bioavailable, it also reduced oxidative stress by 60% in comparison to ferrous sulphate (typical compound in iron supplements ). Oxidative stress has been suggested to contribute to the negative effects of traditional iron supplements on the gastrointestinal tract.
