In this Q&A, Dr. Rhonda Patrick discusses the assessment and treatment of iron imbalances, the impact of urolithin A on mitochondrial health, and the potential longevity benefits of NAD+ boosters. Timestamps include:
-
Q: How do you balance iron deficiency with overload risk?
-
Q: What are the benefits and risks of urolithin A?
-
Q: Can restoring NAD+ slow aging?
How can we accurately assess iron status, and what are the health risks of both deficiency and overload?
Iron balance is delicate. Too little, and the body cannot make enough hemoglobin, leading to iron deficiency anemia with symptoms like fatigue, weakness, and shortness of breath. Too much, and iron accumulates in tissues, driving oxidative stress that can damage the liver, pancreas, and brain. Because the risks sit at both extremes, accurate assessment of iron status is essential.
How to diagnose iron deficiency anemia and distinguish it from other anemia subtypes
Anemia offers a practical entry point into iron diagnostics. It's a condition defined by low hemoglobin, and many people associate it with low iron, but the story can be far more layered. Looking at how physicians distinguish between different types of anemia not only clarifies the logic of iron testing but also shows why iron supplementation is not a universal solution for anemia.
