Q and A: about health and research

Iron deficiency without anemia (IDWA), also called non-anemic iron deficiency or latent iron deficiency , is a common but frequently overlooked condition.  It occurs when your body's iron stores become depleted while your hemoglobin levels remain within the normal range. Because standard blood tests often focus only on hemoglobin, many people are told their iron levels are "normal" even though their iron reserves are running low. As a result, symptoms can persist for months—or even years—before anemia eventually develops. The good news is that iron deficiency without anemia is usually reversible once the underlying cause is identified and iron stores are restored.   What Is Iron Deficiency Without Anemia? Iron is an essential mineral involved in much more than making red blood cells. It is required for: Cellular energy production Oxygen transport Brain function Muscle performance Immune health Hair and nail growth Healthy skin Your body stores excess iron in the form of ...

Glycogen is a vital yet often overlooked component of human metabolism. It plays a crucial role in energy storage and release, bridging the gap between the food we eat and the fuel our bodies need to function. From its discovery by Dr. Dorothy Hansine Andersen to its implications in athletic performance and rare genetic diseases, glycogen has wide-reaching significance in human health. This article explores glycogen in depth—what it is, how it works, how it affects health, and what happens when it goes wrong. What Is Glycogen? Glycogen is a complex carbohydrate—a polysaccharide—composed of many glucose molecules linked together. It serves as the primary storage form of glucose in the human body and can be quickly broken down (hydrolyzed) into glucose when energy is needed. Unlike simple sugars that circulate freely in the blood, glycogen is stored for future use. It acts like an energy bank, allowing the body to deposit and withdraw glucose as needed, especially during physical ac...
