Iron is a critical component of hemoglobin and myoglobin, proteins responsible for transporting oxygen in the blood and muscles. Adequate iron status is essential for cellular energy production, neurological function, and immune health.
Iron deficiency is one of the most common nutrient deficiencies worldwide and may occur even with adequate dietary intake due to poor absorption, increased needs, or blood loss.
Functions:
Enables oxygen delivery to tissues via hemoglobin
Supports mitochondrial energy production
Required for DNA synthesis and cell division
Supports neurotransmitter synthesis and cognitive performance
Plays a role in immune defense and infection resistance
TAILORBLEND uses iron bisglycinate to support efficacy while minimizing gastrointestinal side effects.
Iron is an essential mineral commonly used to support:
Red blood cell formation and oxygen transport
Energy levels and fatigue reduction
Cognitive function, focus, and memory
Immune system function
Exercise performance and endurance
Pregnancy and menstrual health
Iron occurs in both heme (animal-based) and non-heme (plant-based) forms, with heme iron being more readily absorbed.
Animal Sources (Heme Iron):
Red meat, liver
Poultry (dark meat)
Fish and shellfish
Plant-Based Sources (Non-Heme Iron):
Lentils, chickpeas, beans
Tofu and tempeh
Spinach and other leafy greens
Pumpkin seeds, sesame seeds
Fortified cereals and whole grains
Absorption of non-heme iron is enhanced by vitamin C and inhibited by phytates, calcium, tea, and coffee.
Synergistic Nutrients:
Vitamin C: Enhances non-heme iron absorption
Copper: Required for iron transport and mobilization
Vitamin A: Supports iron metabolism and hemoglobin synthesis
B12 + Folate: Essential for red blood cell production
Typical Dosages:
Maintenance: 8–18 mg/day (varies by sex and life stage)
Functional support (low iron stores): 18–30 mg/day
Therapeutic (iron deficiency anemia): 45–65 mg/day (under medical supervision)
Excess iron can cause oxidative stress and organ damage
Do not supplement unless deficiency or increased need is confirmed
Individuals with hemochromatosis or iron overload should avoid supplementation
Iron supplements may cause nausea, constipation, or dark stools
