PubMed indexes 4 records that name Galactooligosaccharides (GOS) and Iron together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Galactooligosaccharides (GOS) and Iron. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

“There is some evidence to show that the use of prebiotics or probiotics (especially Lp299v and GOS) with or without oral iron can improve iron absorption in women and lead to improvement in ferritin levels in women. However, the current evidence does not conclusively show the benefit of these interventions in improving hemoglobin levels in women and children.”

“However, the current evidence may not be substantial to invalidate the recommendation of dietary fiber as an agent to improve dietary iron bioavailability, and absorption. In conclusion, there is a need to conduct further clinical trials with long dietary fiber intervention focusing on population at high risk for iron deficiency.”

“They also report significantly fewer infection-related symptoms, with no significant differences in gut inflammation or enteropathogen carriage (secondary outcomes). Collectively, these findings indicate that while dietary iron absorption is reduced in children with virally suppressed HIV, supplemental and fortificant iron are well absorbed, and co-administration of iron supplements with prebiotics may improve efficacy and safety.”

Search-based evidence indexes have real limits, and it is worth being explicit about them:
NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Galactooligosaccharides (GOS), Iron, and several hundred other substances.
The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
