Can Ferritin Eisenmangel help with longevity?

The question of whether ferritin or iron deficiency can promote longevity is misleading. Ferritin is an iron-storage protein; low ferritin indicates iron deficiency. Iron deficiency causes fatigue, cognitive impairment, and anemia—all factors that reduce quality of life and likely shorten healthspan. There is no robust evidence that deliberately induced iron deficiency extends longevity. On the contrary, chronic iron deficiency can impair cardiovascular and immune function. Some preclinical work suggests moderate iron restriction might reduce oxidative stress, but this is not equivalent to clinical deficiency. The evidence is mechanistic and not translatable to humans. MyBody-X offers tests to measure ferritin levels, but iron deficiency should always be evaluated and treated medically, not misconstrued as an anti-aging strategy. Longevity research emphasizes balanced nutrition, exercise, and metabolic regulation—not micronutrient depletion.
