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.


Brain &amp; Neurons

Model: 20-month-old C57BL/6N male mice (roughly equivalent to 60-year-old humans)
Dosage: 8,000 mg/kg of taurine administered daily via oral gavage for four months

Yale Study Shows How Taurine Reduces Age-Related Inflammation

A new study reveals how taurine helps curb age-related inflammation in aged mice by targeting a key inflammatory pathway in immune cells.

A new study finds that taurine supplementation reduces signs of inflammation and improves some measures of physical function in aged male mice.

Aging &amp; Longevity

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.
