In one line
L-glutamine is one of the 6 ingredients highlighted on the Pawbiotix label, listed in the amino acid role. An amino acid that is a major fuel source for the cells lining the intestines.
Amino acidWhat it is
L-glutamine is an amino acid that serves as a major fuel source for the fast-renewing cells that line the intestines. It is a common ingredient in gut-focused supplements for that reason.
Why it’s in Pawbiotix
Its presence broadens the support-blend story beyond bacteria and fiber, and gives owners one more identifiable, non-mystery ingredient to review before buying.
How it supports the formula
1
Fuels gut-lining cells
L-glutamine is a primary energy source for the cells that line and renew the intestinal wall.
