The amount of elemental iron in 20 mg of iron aspartame is approximately 2-4 mg, though the exact amount depends on the specific formulation. Iron aspartame is a chelated form of iron where the mineral is bound to aspartic acid, making it more bioavailable but reducing the percentage of elemental iron in the compound. This means that only about 10-20% of the total weight is actual iron 1. When taking iron supplements, it's essential to understand the elemental iron content since this is what your body actually uses to address iron deficiency. Iron aspartame is generally well-tolerated compared to other iron supplements like ferrous sulfate, causing fewer gastrointestinal side effects such as constipation or stomach upset. For optimal absorption, take iron supplements on an empty stomach with vitamin C, and avoid taking them with calcium, dairy products, coffee, tea, or antacids, which can reduce absorption.
Some key points to consider when taking iron supplements include:
- The importance of understanding the elemental iron content in the supplement
- The bioavailability of iron aspartame and its potential to cause fewer gastrointestinal side effects
- The need to take iron supplements on an empty stomach with vitamin C for optimal absorption
- The potential interactions with other substances that can reduce iron absorption, such as calcium, dairy products, coffee, tea, or antacids 2, 3, 4.
It's also worth noting that iron deficiency is a significant public health problem, particularly in certain populations, and that oral iron supplementation is a safe and effective means of increasing hemoglobin levels and restoring iron stores 5, 1.
