How To Increase Red Blood Count? Step By Step

Your red blood cell count is a basic health number that matters a lot. It tells you how well your body moves oxygen from your lungs to your muscles and organs. If your count is low, you feel tired, weak, and short of breath. Raising it is possible, but the steps depend on why it is low. Here is the direct answer: To increase your red blood count, you first need to fix the underlying cause. This usually means eating more iron, vitamin B12, and folate. For some people, it means treating a chronic disease or stopping blood loss. The fastest approach combines diet changes, supplements if needed, and medical treatment for any condition causing the low count. Always work with a doctor to confirm the cause before trying anything on your own.

What Causes a Low Red Blood Count?

Your red blood cells are made in your bone marrow. They live for about 120 days. Your body constantly makes new ones to replace old ones. When the number drops, it is called anemia. The most common cause is not enough iron. The CDC reports that iron deficiency is the most common nutritional deficiency in the United States, affecting nearly 10% of women of childbearing age.

Other causes include low vitamin B12 or folate. These vitamins are needed to build red blood cells properly. Chronic diseases like kidney disease or rheumatoid arthritis can also lower your count. Blood loss from heavy periods, ulcers, or surgery is another major cause. Some people have genetic conditions like sickle cell disease or thalassemia. Rarely, bone marrow problems like aplastic anemia are the cause.

Knowing the cause is step one. Without this, any attempt to raise your count is guesswork. A simple blood test called a complete blood count (CBC) tells your doctor your exact numbers. Additional tests check iron, B12, and folate levels.

How To Increase Red Blood Count With Diet

Food is the foundation. Your body needs specific nutrients to make red blood cells. The three most important are iron, vitamin B12, and folate. Getting enough of these through food is the safest first step.

Iron-rich foods come in two types. Heme iron is from animal sources. Your body absorbs it easily. Red meat, liver, chicken, and fish are good sources. Non-heme iron is from plants. It is harder to absorb. Spinach, lentils, beans, and fortified cereals provide it. Eating vitamin C with non-heme iron helps absorption. Squeeze lemon on spinach or eat an orange with your beans.

Vitamin B12 is mostly found in animal products. Meat, fish, eggs, and dairy are the main sources. People who eat no animal products often need a supplement because plants do not contain B12. Fortified foods like some plant milks and breakfast cereals can help, but levels vary.

Folate is found in dark leafy greens, asparagus, Brussels sprouts, and beans. The name comes from the Latin word for leaf. Cooking can destroy folate, so eat some raw or lightly steamed. The National Institutes of Health notes that folic acid, the synthetic form, is better absorbed than natural folate.

A single food will not fix a low count. You need a consistent pattern of eating these foods daily. Most adults need about 8 to 18 milligrams of iron per day depending on age and sex. Pregnant women need more. A doctor can tell you your specific needs.

Do Supplements Help Increase Red Blood Count?

Supplements can work when diet is not enough. But they are not a shortcut. Research published in JAMA Internal Medicine found that iron supplements raise hemoglobin levels in people with iron deficiency anemia within two to four weeks. The effect is real. But taking iron when you do not need it can cause harm.

Iron supplements cause constipation, nausea, and stomach pain in many people. The American Gastroenterological Association reports that up to 40% of people taking oral iron have gastrointestinal side effects. Taking iron with food reduces these effects but also reduces absorption. Vitamin C helps absorption, so take iron with a glass of orange juice if your stomach tolerates it.

Vitamin B12 supplements are safe and well absorbed even at high doses. This is because only a small amount is absorbed through your intestine. The rest is absorbed directly if you take a sublingual (under the tongue) form. People with pernicious anemia, a condition where the body cannot absorb B12 from food, need injections or high-dose oral supplements.

Folic acid supplements are often given to pregnant women to prevent birth defects. They also help raise red blood count in folate deficiency. Taking folic acid can mask a B12 deficiency, so doctors usually check both levels before prescribing.

Do not take supplements without a blood test. Taking iron when your levels are normal can cause iron overload. This damages your liver and heart over time. The same applies to other nutrients. More is not better.

Medical Treatments for Low Red Blood Count

Some causes of low red blood count need medical treatment, not just diet or supplements. Chronic kidney disease is one example. The kidneys produce a hormone called erythropoietin (EPO) that tells your bone marrow to make red blood cells. When kidneys fail, EPO levels drop. Synthetic EPO injections are a standard treatment for people on dialysis.

Blood loss from heavy periods can be treated with hormonal birth control or other medications. Bleeding from stomach ulcers requires treating the ulcer itself. The underlying cause must be addressed. Otherwise, you are just replacing blood that keeps leaving.

In severe anemia, blood transfusions are used. This is a temporary fix. A transfusion raises your count immediately but does not fix the root problem. It is reserved for emergencies or when other treatments have failed.

Bone marrow problems are rare but serious. Aplastic anemia, myelodysplastic syndromes, and leukemia all affect red blood cell production. Treatment involves chemotherapy, immune-suppressing drugs, or a bone marrow transplant. These are complex conditions managed by a hematologist.

Lifestyle Factors That Affect Red Blood Count

Exercise affects your red blood count in two ways. First, regular aerobic exercise stimulates your body to make more red blood cells over time. This is a normal adaptation to increased oxygen demand. Second, intense exercise can cause a temporary drop in red blood count due to something called foot-strike hemolysis. This is the destruction of red blood cells from repeated impact, common in long-distance runners.

Dehydration can make your red blood count appear higher than it really is. This is because the plasma part of your blood gets thinner or thicker depending on water intake. A dehydrated person has less plasma, so the red blood cells are more concentrated. This gives a falsely high count. Drink enough water before blood tests to get an accurate reading.

Alcohol affects red blood cell production directly. Heavy drinking interferes with folate absorption and damages bone marrow. The National Institute on Alcohol Abuse and Alcoholism states that alcohol abuse is a common cause of macrocytic anemia, where red blood cells are larger than normal and fewer in number. Cutting back on alcohol can improve your count over weeks.

Sleep matters too. Your body repairs and produces cells during sleep. Chronic sleep deprivation may reduce red blood cell production, though the evidence is not as strong as for other factors. Getting seven to nine hours of sleep is good for many health reasons, and this may be one of them.

Common Misconceptions About Increasing Red Blood Count

Many people believe that eating raw liver or drinking beet juice will fix a low red blood count. Raw liver carries a risk of foodborne illness and has no advantage over cooked liver. Beet juice contains nitrates that may improve blood flow, but there is no strong evidence that it raises red blood cell count directly.

Another myth is that taking a multivitamin with iron is enough for everyone. Multivitamins contain a small amount of iron, usually 18 mg or less. This is fine for prevention but rarely enough to treat an existing deficiency. You need higher doses under medical supervision.

Some people think that eating more protein alone will increase red blood cells. Protein is needed for hemoglobin, but iron, B12, and folate are the limiting factors. Eating extra protein without these nutrients will not raise your count.

Avoid supplements that claim to boost red blood count without evidence. Products marketed as blood builders or oxygen boosters often contain herbs or compounds with no proven benefit. As of 2026, there is no clinical evidence that any herbal supplement reliably increases red blood cell count in humans. Stick to nutrients with solid research behind them.

When to See a Doctor

Do not self-diagnose a low red blood count. The symptoms of anemia — fatigue, weakness, pale skin, shortness of breath, dizziness — overlap with many other conditions. The only way to know for sure is a blood test.

See a doctor if you have these symptoms for more than a few weeks. If you have chest pain, rapid heartbeat, or trouble breathing, seek medical attention immediately. These can be signs of severe anemia that needs urgent treatment.

Pregnant women should have their iron and red blood count checked early in pregnancy. Anemia during pregnancy increases the risk of preterm birth and low birth weight. The American College of Obstetricians and Gynecologists recommends routine screening for all pregnant women.

People with chronic conditions like kidney disease, rheumatoid arthritis, or cancer should have regular blood counts as part of their care. These conditions often cause anemia that requires specific treatment beyond diet changes.
