Dietary Components: Dietary components significantly influence iron absorption. Vitamin C enhances iron absorption by converting it to a more easily absorbable form, while calcium and dairy products can inhibit it. A study by Hallberg et al. (1986) found that combining iron with vitamin C-rich foods, like orange juice, can increase absorption rates. On the other hand, phytates found in whole grains and legumes and tannins in tea and coffee can impede iron absorption.
Timing of Consumption: The timing of iron supplement intake matters. It is generally recommended to take iron supplements between meals to maximize absorption. Consuming iron with food can reduce absorption due to the presence of inhibitors, while empty stomach absorption may lead to gastrointestinal discomfort. Research indicates that taking supplements on an empty stomach can double the absorption rate compared to taking them with meals (Benoist et al., 2008).
Individual Gut Health: An individual’s gut health plays a crucial role in iron absorption. Conditions such as celiac disease, Crohn’s disease, or gastric surgeries can affect the body’s ability to absorb iron. For example, individuals with celiac disease may have damaged intestinal lining, which impairs nutrient absorption, including iron. A study by Halsted et al. (2010) highlights that poor gut health can lead to iron deficiency anemia.
Type of Iron Supplement: Different types of iron supplements vary in their absorption rates. Ferrous sulfate is generally more easily absorbed than ferric forms. Liquid iron supplements may also be better absorbed than tablets. According to a systematic review by Pahl et al. (2019), ferrous bisglycinate is another well-absorbed option free of the gastrointestinal side effects commonly associated with iron supplementation.
Presence of Other Medications: Other medications can affect iron absorption. Certain drugs, like antacids or proton pump inhibitors (PPIs), can decrease stomach acidity, which is necessary for iron solubility and absorption. Low acidity can hinder the conversion of ferric iron to ferrous iron, making it less absorbable. A study by Gemmel et al. (2008) indicated that patients on PPIs showed lower iron levels compared to those not taking these medications.

By understanding these factors, individuals can better manage their iron supplementation for improved absorption and overall health.

Should I Take Iron With Food or On an Empty Stomach Before Bed?
