If you take a multivitamin, there are good reasons to consider one without iron. The body tends to hold onto extra iron -- and if you take too much, that can be dangerous.

So, you should generally notice an improvement in symptoms and labs by 1 month. (Some chronic conditions, including renal failure, can cause anemia, which may take longer to correct the iron levels.)
Where is iron absorbed?
As a pharmacist, I'd be remiss to not talk about iron absorption: Iron is absorbed in the duodenum and upper jejunum. In persons with normal serum iron stores, 10% of an oral dose is absorbed, and this is increased to 20% to 30% in persons with inadequate iron stores. Food and alkaline stomach juices will decrease absorption, so iron tablets are often times prescribed with ascorbic acid (vitamin C) to be taken concurrently. Dosing is generally the 325mg ferrous sulfate tablets either once, twice or even up to 3 times a day.
Is iron a cation?
Technically no, as we do it all the time in the way of food and multivitamin ingestion. Iron, Ferrous, attached to a moiety like sulfate, gluconate, etc, is a metal, FE 3+, hence a cation.

Iron is most commonly known for red blood cell production and oxygen carrying capacity of the blood. One of the most common side effects is either constipation or diarrhea as it is a metal and therefore has the potential to be a GI irritant.
Does vitamin D deficiency affect bacteria?
Another direct quote from the same site, "Vitamin D deficiency leads to a change in the intestinal bacterial populations that make and supply us daily with 8 B vitamins. The B vitamins never came from the food, they have always been supplied in the daily doses we need by the bacteria we carried in our intestine. But the “healthy” bacteria need our vitamin D to thrive, when we don’t have enough we don’t pass down D to the bacteria and “unhealthy” bacteria who don’t make B vitamins replace our healthy bacteria."

What is the role of vitamin D in anemia?
Vitamin D is a prohormone nutrient, which is involved in skeletal and extra-skeletal functions. Iron is another essential nutrient that is necessary for the production of red blood cells and oxygen transport. This element plays important roles in enzymatic systems including those required for Vitamin D activation. To the best of our knowledge, there is no exclusive review on the relationship between iron deficiency anemia (IDA), as the most prevalent type of anemia, and Vitamin D deficiency and the effect of recovery from iron deficiency on Vitamin D status. The aim of this study was to conduct a systematic search of observational and clinical trials in this field. The databases of PubMed, ProQuest, Cochrane Library, ISI Web of Knowledge, and SCOPUS were searched comprehensively. English-language human studies conducted on iron deficient patients or interventions on the effect of iron therapy on Vitamin D were extracted (n= 10). Our initial search yielded 938 articles. A total of 23 papers met the inclusion criteria. Thirteen studies were excluded because they were not relevant or not defining anemia types. The final analysis was performed on ten articles (3 cross-sectional and 7 interventional studies). Observational data indicated a positive relationship between iron status and Vitamin D, while trials did not support the effectiveness of iron supplementation on improving Vitamin D status. The mechanism underlying this association may involve the reduction of the activation of hydroxylases that yield calcitriol. Future randomized controlled trials with large sample sizes and proper designs are needed to highlight underlying mechanisms.
What is the vitamin D in the body?

Anemia and VDD have been observed simultaneously. [10] Some recent studies blame IDA for VDD because of their linked metabolism.[11,12,13] The results of studies in this area are inconsistent due to heterogeneity in study objectives and lack of determining the etiology of anemia. There are also several trials evaluating the effect of iron intake on Vitamin D concentration as their primary or secondary outcomes,[14,15,16,17,18,19,20] but there is no exclusive review on the effect of iron deficiency or its replenishment on Vitamin D status.
Where is vitamin D produced?
As mentioned before, Vitamin D is activated in the body by two sequential steps. In the first step, 25(OH)D3is produced in the liver. A kind of cytochrome P450, CYP2R1, is responsible for this stage. The second hydroxylation happens in kidneys and some other tissues by the virtue of CYP27B1 to form 1,25(OH)2D3.
Does iron affect vitamin D?
Pure iron supplementation did not significantly affect the serum concentration of any of the Vitamin D metabolites in most interventions.[16,17,19,20] Heldenberg et al. observed significant increases in both 25(OH)D and 24,25-dihydroxy Vitamin D levels in a group of infants with IDA and VDD.[15] Although children took Vitamin D as a routine treatment, they were Vitamin D deficient and showed positive results after iron injection. In a group of iron-deficient women consuming a placebo fruit juice (P) or iron-fortified fruit juice (F), 25(OH)D decreased in both groups (P< 0.001).[14] Toxqui et al. provided an iron (Fe group) or iron and Vitamin D-fortified (Fe plus D group) skimmed milk for iron-deficient women.[18] After 16 weeks, 25(OH)D significantly increased in the Fe+D group (P< 0.001) without any change in the Fe group. Quality assessment using Down's checklist indicated missing data about confounders, blinding, and randomization.
