Participants: Older adults at risk for dementia. 
Dosage: 2 g/day of DHA

While it entered the brain, two years of high-dose supplementation revealed no cognitive protection from pure docosahexaenoic acid (DHA) in older adults without dementia.

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.

Model: Eight-week-old C57BL/6J mice treated with 300 mg/kg/day of D-galactose by subcutaneous injections for eight weeks
Dosage: 100 mg/kg/day of NMN in drinking water for eight weeks and 5 × 10 5 hUC-MSCs suspended in 150 µL of PBS via tail vein injection on the first day of weeks five through seven

NMN Enhances Stem Cell Therapy’s Effects on Immune Aging in Latest Study

Combining NMN with umbilical cord–derived stem cells improved motor and cognitive function while reducing markers of immune aging in mice with chemically induced aging.
