Expert opinions

Dr. Strunz

Strunz recommends 5 to 20 g L-glutamine daily and describes it as the primary fuel for enterocytes and lymphocytes. He often combines it with zinc carnosine and vitamin D3. He considers it safe long-term in healthy adults, with caution in severe liver or kidney disease because glutamine is metabolized to ammonia.

Recommended dose: 5–10 g
