Iron is crucial for producing hemoglobin, the protein in red blood cells that carries oxygen throughout your body. When you're low on iron, your cells don't get enough oxygen—leading to fatigue, weakness, and brain fog.

Iron deficiency is especially common in women, vegetarians, and those with chronic health conditions. If you feel unusually tired and lightheaded, it’s worth checking your iron levels with a simple blood test.

Iron supplements come in several forms—ferrous sulfate is the most common, but some people find other types like ferrous bisglycinate gentler on the stomach. Vitamin C helps with absorption, so many supplements include it or recommend taking them with orange juice.

Be consistent, but careful. Too much iron can be toxic, especially if not needed. Never supplement without confirming a deficiency through bloodwork and medical advice.
