Model: Apoe−/− C57BL/6J mice fed a high-fat diet
Dosage: 1 × 109 CFU per 0.1 mL of Bacteroides uniformis administered to mice via oral gavage for 12 weeks and 25 mg/kg of pentadecanoic acid via oral gavage three times per week for eight weeks

New Study: Gut Bacteria Metabolite Reduces Arterial Plaque Burden by 50%

Researchers identified pentadecanoic acid, a gut-bacteria-produced metabolite, that lowered LDL cholesterol and limited arterial plaque buildup in mice.

Dosage: 0.5 mg/kg of isolated mitochondria injected every two days for six injections in the tail vein

Mitochondrial Transplantation Rejuvenates Aging Hearts, Study Finds

Transplantation of the cell’s powerhouses (mitochondria) improves heart function by restoring mitophagy (the cellular process that clears damaged mitochondria) in a mouse model of cardiac aging.
