Side Effects of Monosodium Glutamate

Side Effects of Monosodium Glutamate

Monosodium glutamate (MSG) is a common food additive used to enhance flavor, but some people report experiencing side effects after consuming it. The most commonly reported symptoms include:

  • Headaches and migraines
  • Flushing, sweating, and numbness
  • Muscle tightness and weakness
  • Dizziness and lightheadedness
  • Rapid heartbeat
  • Chest pain and difficulty breathing

However, the evidence linking MSG to these symptoms is mixed. Some studies have found no difference in symptoms between MSG and placebo. Doses of 5g or more of MSG consumed without food may be more likely to cause symptoms.

MSG is generally considered safe by regulatory bodies when consumed in typical food amounts. It is naturally present in many foods and your body cannot distinguish between MSG and naturally occurring glutamate.

More research is still needed on the potential side effects of MSG, especially in sensitive individuals. If you experience adverse reactions after consuming MSG, it's best to avoid it or speak to your doctor. But for most people, typical dietary amounts of MSG are unlikely to cause harm.
