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: 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.
