BIOAVAILABILITY OF FORTIFERRUM®+
It was performed a comparative study of the absorption and bioavailability of FORTIFERRUM®+ liposomal iron with other iron salts contained in other products marketed. The study showed that both absorption and bioavailability of ferric pyrophosphate of FORTIFERRUM®+ are notoriously higher than those presented by other iron compounds used in the comparison.
It was proved that FORTIFERRUM®+ absorption is between 2 to 4 times higher than for the other salts as free ferric pyrophosphate, ferrous sulfate or iron gluconate which confirms the stability and effectiveness of FORTIFERRUM®+ liposomal iron.
To improve its effectiveness and compensate iron deficiencies in an optimal way, FORTIFERRUM®+ formula contains also vitamin C which is the most potent iron absorption enhancer. Vitamin C has the ability to reduce the iron in order to prevent the reaction with other compounds forming insoluble salts whose absorption is greatly reduced.
The significant increase in iron bioavailability caused by vitamin C is maintained even in the presence of inhibitors such as phytates, tannins or calcium and also in the presence of the characteristic alkaline pH of the intestine where the absorption of iron takes place. Vitamin C contained in FORTIFERRUM®+ not only enhances the absorption of liposomal iron, but also enhances the absorption of iron ingested with the diet. Moreover, vitamin C has other beneficial properties that improve the hematologic status since it facilitates the mobilization of iron deposits and active enzymes capable of converting folate to its active form protecting erythrocytes against oxidative damage.
