Iron is the most common nutrient deficiency in the developed world, particularly affecting women and pregnant individuals, with half experiencing deficiency at some point. Symptoms include fatigue, weakness, hair loss, and pallor, but low iron levels also impact other systems, such as causing restless leg syndrome, cognitive impairment, and hormonal imbalances. Iron is crucial for thyroid function and immune response, and supplementation can improve conditions like heavy menstrual bleeding and unexplained infertility. Despite its benefits, many avoid iron supplements due to side effects. Cyto-Matrix’s Iron Matrix offers chelated iron bis-glycinate, reducing digestive issues, and includes vitamin C, B6, B12, folic acid, magnesium, and copper to enhance absorption and red blood cell production.
