Supplement with iron bisglycinate and Vitamin C for absorption.
Iron deficiency affects everything from cognitive function to physical endurance.
Low iron often goes undetected until your ferritin stores are completely depleted.
Track your iron storage and transport markers to ensure peak performance.
Supplement with iron bisglycinate and Vitamin C for absorption.
Confirm that both circulating iron and stored iron (Ferritin) are within optimal ranges, not just "normal."
Take iron supplements with Vitamin C and avoid consuming tea, coffee, or calcium within 2 hours of your iron dose.
Work with a professional to determine if low iron is due to diet, malabsorption (gut health), or blood loss.
