Model: Eight-week-old male C57BL/6J mice treated with 400 mg/kg/day of D-galactose via intraperitoneal injection for 12 weeks to induce accelerated aging.
Dosage: 400 mg/kg/day of Antarctic krill oil administered by oral gavage for 12 weeks, alongside D-galactose treatment. A comparison group received 400 mg/kg/day of fish oil under the same conditions.

Krill Oil Preserves Muscle Strength and Mitochondrial Health During Accelerated Aging

Daily krill oil supplementation preserves muscle strength, endurance, and mitochondrial health in mice with accelerated aging, outperforming fish oil.

Protein Restriction and Longevity: Can Limiting Protein Intake Support Healthy Aging?

University of Wisconsin researchers examine how reducing dietary protein intake may reshape nutrient sensing, metabolism, mitochondrial function, and other pathways linked to healthier aging.

(One of the leading authors on the Cell Press Blue article, Dr. Dudley Lamming | University of Wisconsin)

Researchers examine how restricting protein intake can improve metabolic health and influence aging-related pathways to extend healthspan and lifespan.

Model: Young acquired niacin dependency (ANDY) mice. 
Dosage: 30 mg/kg/day of niacin

Mice engineered to have low body-wide NAD+ levels exhibit a shortened lifespan and widespread physical decline, which is largely reversed with the NAD+ booster niacin. 

NAD+ (nicotinamide adenine dinucleotide) levels were lower among older adults with frailty—an age-related condition associated with increased vulnerability to disability, disease, and death.
