Model: Otherwise healthy adults aged 40 and older
Dosage: 15 g of the multi-ingredient supplement dissolved in up to 500 mL of water or juice, given each day orally for six months

Can a Nutritional Supplement Prevent Vascular Aging? 6-Month Human Trial Results

A six-month human trial found that a multi-ingredient nutritional supplement improved vascular health, reducing arterial stiffness and lowering systolic blood pressure.

A six-month randomized trial found that a multi-ingredient supplement improved vascular health markers, including arterial stiffness and blood pressure.

Cardiovascular

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: 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.

A gut bacterial metabolite reduced arterial plaque buildup by about 50% in mice, revealing a potential link between gut microbes and cholesterol regulation.

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.
