L-Glutamine Fortifies Brain and Gut Health: How to Get Enough?
During periods of high stress, L-glutamine supplementation may be beneficial to body and mind.L-glutamine is a powerhouse amino acid that can fortify your gut and uplift your mood—a hidden gem during challenging times.L-glutamine plays a crucial role in maintaining the health of your gut lining and balancing brain function.

It is classified as a non-essential amino acid because the body can produce it on its own. However, it becomes conditionally essential when demand increases, such as intense stress, illness, disease, or strenuous exercise.

Potential Adverse Effects
L-glutamine is generally considered safe for most people when taken in appropriate amounts. However, some potential adverse effects, especially when taken in high doses, Subhadra said, can include mild gastrointestinal discomfort, such as bloating or gas.“As we continue to understand the gut-brain axis and the role of the microbiome in overall health, it becomes clear that maintaining a healthy gut is more critical than ever,” Subhadra said.
