Your immune system protects you from infections. One way it does this is by releasing pro-inflammatory substances called cytokines—small proteins that act like messengers, telling immune cells when and where to respond.
Cytokines are essential for fighting off germs, but too much of them can make you feel worse. Excess inflammation can drain your energy, affect how your body works, and slow recovery.
As your body starts to heal, it works to remove these inflammatory signals. Special immune cells clean them up, and your organs—like the liver and spleen—help process them.
New research suggests the kidneys may also play an important role by filtering inflammatory molecules out of the blood.
Methionine is an amino acid found in high-protein animal-based foods like meat, eggs, and dairy. In a recent animal study, researchers found that methionine helped protect against the harmful effects of too much inflammation during infection.
It appeared to support kidney function, helping the body clear excess cytokines from the bloodstream. This may have reduced some of the negative effects of inflammation, without affecting the body’s ability to fight the infection.
This research is still in its early stages and was conducted in animals, not people. So, it’s too soon to say whether methionine support would help humans recover from infections.
However, the findings highlight an interesting point: your kidneys may play a greater role in managing inflammation than we once thought.
Methionine is processed in the body into another compound called homocysteine. To keep this process balanced, your body needs adequate amounts of vitamins B6 and B12, and folate.
Getting these nutrients from a healthy diet helps support normal metabolism and overall health.
Methionine may help the body manage inflammation during infection—at least in early animal studies. For now, focus on a balanced diet and healthy habits while researchers continue to learn more.
