All products from Irongrowth line are formulated including AB-FORTIS as a source of iron.
AB-FORTIS is a micro-encapsulation system that allows delivering 100% of the iron RDA in a single dose, with high bioavailability and no adverse effects in taste or during the digestion. This ingredient was developed and patented by the Spanish biotech AB-BIOTICS.
A clinical study carried out in healthy patients showed that AB-Fortis has a bioavailability at least equivalent to ferrous sulphate, considered a very bioavailable iron salt. Transferrin saturation displayed a clear change in response to the intake of both products, indicating that iron had been absorbed in a significant amount. This study was published in the well-known European Journal of Nutrition in 2014. Ferrous sulfate is the most common iron salt in nutritional supplements, but it causes a number of gastrointestinal side effects that provoke the rejection of many consumers. AB-FORTIS, thanks to its microencapsulation system, protects iron and minimizes these side effects.
