Your Oxygen Carrier
Hemoglobin is the protein inside your red blood cells that grabs oxygen from your lungs and delivers it to every cell in your body. Each hemoglobin molecule can carry 4 oxygen molecules. Without enough hemoglobin, your cells are essentially suffocating—they can't produce the energy you need to function.
What is Hemoglobin?
Hemoglobin is an iron-rich protein that makes your blood red. It binds oxygen in your lungs and releases it to your tissues. Your hemoglobin level tells us how well your blood can carry oxygen—essentially, how well your body is being fueled at the cellular level.
↑ What High Hemoglobin Means
Your blood is carrying more oxygen than typical. While that sounds good, it actually makes your blood thicker and harder to pump. This often happens with dehydration, living at high altitude, or smoking.
Common symptoms:
Headaches · Dizziness · Flushed complexion · Blurred vision · Itching after showers
↓ What Low Hemoglobin Means
Your cells aren't getting enough oxygen delivery. This is anemia—and it explains why you might feel exhausted, get winded climbing stairs, or struggle to concentrate. Your body is running on empty.
Common symptoms:
Persistent fatigue · Shortness of breath on exertion · Pale skin and gums · Dizziness · Cold hands/feet · Brittle nails · Difficulty concentrating
Why It Matters
When normal:
Sustained energy throughout the day
Sharp mental focus
Good exercise tolerance
Healthy skin and nail color
Risks if abnormal:
Chronic fatigue that sleep doesn't fix
Shortness of breath during normal activities
Difficulty concentrating
Dizziness and rapid heartbeat
What Can Cause Abnormal Levels?
Iron Deficiency
70% likelyIron is the core of hemoglobin—without it, your body can't make enough. This is the #1 cause, especially in women with heavy periods.
B12 or Folate Deficiency
50% likelyThese vitamins are essential for producing red blood cells. Without them, you make fewer cells.
Chronic Blood Loss
Heavy periods, GI bleeding, or frequent blood donation depletes iron stores.
Chronic Disease
Kidney disease, cancer, and autoimmune conditions can suppress red blood cell production.
What You Can Do
Iron-rich foods: beef liver, oysters, spinach, lentils with vitamin C
Impact: +1-2 g/dL hemoglobin \u00B7 Timeline: 4-8 weeks
Avoid tea/coffee within 1 hour of meals (blocks iron absorption)
Impact: Prevents 60% absorption loss \u00B7 Timeline: Immediate
If lifestyle changes aren't enough:
Iron supplement: 325mg ferrous sulfate with orange juice
Impact: +2-3 g/dL \u00B7 Timeline: 8-12 weeks
B12: 1000mcg daily if deficient or vegetarian
Impact: Supports RBC production \u00B7 Timeline: 4-8 weeks
Recommended retest: 3 months after treatment
