Magnesium-L-theanine (MgT) protects intestinal barrier integrity and reduces hepatic steatosis in chronic variable stress models
In preclinical chronic variable stress (CVS) models, MgT preserved epithelial barrier architecture, restored tight junction and mucus-associated proteins, normalized intestinal nutrient transporter expression, and attenuated hepatic steatosis, oxidative stress, and iron-driven metabolic damage. These effects were linked to reactivation of NAD+/SIRT1 and PPARγ signaling pathways, with co-administration of nicotinamide riboside further potentiating responses.

Frequently Asked Questions
What is magnesium-L-theanine?▼
Magnesium-L-theanine (MgT) is a nutritional compound that combines the mineral magnesium with L-theanine, a natural amino acid found in green tea.
How does MgT affect the gut-liver-brain axis under chronic stress?▼
MgT protects intestinal barrier integrity, improves nutrient transport, reduces liver fat accumulation, and limits oxidative and inflammatory damage, thereby supporting communication between the gut, liver, and brain.
Does MgT have any clinical evidence in humans?▼
Human studies of magnesium and L-theanine supplementation separately report anxiolytic, antidepressant, sleep-promoting, and anti-inflammatory benefits, but specific clinical trials of the MgT combination for chronic stress-related multisystem pathology are not yet available.
Can MgT be combined with other supplements?▼
Yes, co-administration with the NAD+ precursor nicotinamide riboside further potentiates MgT's protective effects by reinforcing NAD+ availability and downstream metabolic control.
