Rhonda Patrick: This One Supplement Might Stop You from Getting Sick

Key Takeaways

• Take L-glutamine (5g daily) for immune support, especially during stress, travel, or illness exposure.
• Increase glutamine dosage to 15-20g/day (split into 5g doses) during high-risk periods like family illness or flu season.
• Combine with creatine for potential synergistic immune benefits (anecdotal evidence).
• Avoid high-dose glutamine if you have active colon or liver tumors (cancer cells utilize glutamine aggressively).
• Consider glutamine for gut health (animal studies show it supports gut barrier function, though human data is limited).

Supplements & Protocols Mentioned

• L-glutamine: 5g daily maintenance dose, up to 15-20g/day (split into 5g doses) during immune challenges.
• Creatine: Taken alongside glutamine (specific dosage not mentioned).

Notable Quotes

“I personally am not scared of getting cancer from taking glutamine. If I had a colon tumor… those would be the only types of situations that I would be worried about.”

Bottom Line

Experiment with L-glutamine supplementation (5-20g/day) for immune and gut support, especially during periods of stress or illness exposure, but avoid if you have active gastrointestinal cancers.
