Our Members Asked:
Taking 2 grams of L-glutamine in water on an empty stomach (as directed) caused me to be nauseous, dizzy and anxious. Is this a normal side effect of glutamine?
Answer:
Glutamine is a naturally occurring amino acid and is generally safe at the dose you used and even several times higher. However, as noted in our Muscle & Workout Supplements Review, nausea and other gastrointestinal side effects can occur, and less frequently, headache and dizziness have been reported. Also be aware that people who are sensitive to monosodium glutamate (MSG -- a food flavoring agent) should use glutamine with caution, as the body metabolizes glutamine to glutamate. This can cause symptoms such as headache, nausea, flushing, and anxiety in people with this sensitivity if glutamine is taken without food.
For more information about side effects from glutamine, see the Concerns and Cautions section of our Muscle & Workout Supplements Review, which also discusses what glutamine can and cannot do based on clinical studies.
