Natural Factors Micronized L-Glutamine 500 mg 60 Capsules

This L-glutamine supplement provides 500 mg of micronized L-glutamine per capsule, a naturally occurring amino acid involved in muscle recovery, intestinal health, and immune function. L-glutamine is one of those supplements people often end up looking into if they're trying to optimize for recovery after training or support gut health, because it's already used by both muscle cells and cells lining the digestive tract.

Like a lot of supplements, the goal isn't really to force your body to do something new. You're simply providing more of an amino acid your body already uses every day. If recovery or gut health is something you're intentionally trying to improve, this is one of those foundational nutrients that often becomes part of the conversation.
