HonokiolNew
Honokiol is a lignan compound extracted from Magnolia officinalis bark, long used in traditional Chinese and Japanese herbal formulas for anxiety and digestive complaints. Preclinical interest surged after a 2022 study found honokiol extended lifespan and improved healthspan markers in mice through activation of AMPK, a key cellular energy-sensing pathway also targeted by metformin and exercise. Dedicated human clinical trials of isolated honokiol for longevity or healthspan endpoints do not yet exist; human evidence for honokiol is currently limited to anxiolytic and oral-health effects, usually as one ingredient within multi-herb combination formulas rather than a standalone extract.
Mechanism of Action
Honokiol crosses the blood-brain barrier and acts as a positive allosteric modulator of GABA-A receptors, which is thought to underlie its traditional anxiolytic use. Preclinically, it activates AMPK and has been shown to modulate SIRT3, a mitochondrial sirtuin linked to cellular stress resistance — the proposed basis for its lifespan-extension effect in mouse studies. It also has demonstrated anti-inflammatory and antioxidant activity in cell and animal models.
