Akkermansia muciniphila
Akkermansia muciniphila is a mucin-degrading gut bacterium that strengthens intestinal barrier function via its outer membrane protein Amuc_1100, which activates TLR2 signaling to enhance tight junctions, reduce inflammation (via AMPK activation and NF-κB inhibition), and promote GLP-1 secretion. A 2019 RCT (n=32) found pasteurized A. muciniphila improved insulin sensitivity (+28%), reduced insulinemia (-34%), and lowered cholesterol (-8.7%). Pasteurization preserves Amuc_1100 while eliminating live bacteria, explaining why heat-killed forms retain efficacy. Response depends on baseline gut Akkermansia levels.

Resveratrol is a bioactive molecule found in plant sources such as grapes, peanuts, blueberries, and, famously, red wine. Resveratrol has anti-inflammatory and antioxidant properties that benefit cardiovascular function, glycemic control, and lipid metabolism. Although it’s promoted for lifespan extension, there’s no evidence for this in humans and limited evidence in animals.
