Neutrophils %

Neutrophils are the most common type of white blood cell in your blood. They are made in the bone marrow and travel through your bloodstream, ready to fight off bacteria, fungi, and other germs. When your body senses an infection or injury, neutrophils rush to the area to help protect you.

They work by swallowing germs (phagocytosis), releasing chemicals to kill invaders, and forming special traps to catch and destroy harmful microbes. Neutrophils also help clean up damaged tissue and support healing. Scientists have discovered that neutrophils are not all the same—there are different types with unique jobs, including helping with tissue repair and even influencing other immune cells.

Neutrophils make up about 60–70% of your white blood cells and are vital for protecting against infection.

If your neutrophil percentage is higher than normal, it may mean your body is fighting an infection, dealing with inflammation, or responding to stress. High neutrophil levels can also be seen in chronic diseases like heart disease, autoimmune conditions, or cancer. Low neutrophil percentages can make it harder for your body to fight off infections and may be caused by certain medications, bone marrow problems, or viral illnesses. Neutrophils also play a role in allergies, asthma, and healing after injury. Their activity is influenced by your diet, sleep, stress, and even the bacteria living in your gut. Some nutrients, like vitamin B3, protein, and healthy fats, help neutrophils work properly, while deficiencies can make you more likely to get sick.

• Infections: Bacterial infections typically increase neutrophil count.

• Stress and inflammation: Physical or emotional stress can cause short-term elevations.

• Medications: Steroids, chemotherapy, or antibiotics can lower counts.

• Autoimmune or bone marrow disorders: May cause low or unstable levels.

• Strengthen immune defenses: Prioritise nutrient-dense foods high in vitamin C, zinc, and antioxidants.

• Rest and recovery: Chronic sleep deprivation or overtraining can weaken immune resilience.

• Address infections early: Seek medical care for unresolved or recurrent infections.

• Reduce chronic inflammation: A Mediterranean-style diet, regular movement, and stress regulation help maintain balance.
