L-Glutamine

The general take
Rhonda Patrick uses L-glutamine as a preventive immune support supplement, taking 5 grams daily and ramping up to 15-20 grams during high-risk periods like travel or illness exposure. She spreads the doses out (5 grams at a time) rather than taking it all at once because it can be hard on the gut.

…rhonda patrick discussing glutamine supplementation for immune support
“And I started taking glutamine. Now I take it just, I only take five grams on a daily basis. But if, if my son's sick, if there's any exposure, if it's like during the season, if I'm traveling, I go up to 15, I go up to 20. All at once? Cause it can be a little hard on the gut. Not all at once, not all at once. I usually do it like in fives. So I do five grams, five grams, five grams.”
