The next point as you said in case of sodium feredetate ,(i.e.) added dose of Vitamin c
tablets can be helpful.but unfortunately most of V-C
tablets available in our market is formulated by (major proportion )Sodium ascorbate and(small proportion ascorbic acid). In iron transfer from Stomache wall ,sodium ascorbate will hardly contribute as it is in the neutralised salt form and that too with strongly associated with sodium.This bond will only break in acidic pH.
