Model: 39 adults between 18 and 30 years old and 36 adults between 65 and 80 years old
Dosage: ∼595 mg NO3− twice daily from two 70 mL shots of nitrate-rich beetroot juice

Human Trial Finds Nitrate-Enhanced Juice Lowers Blood Pressure

A new human trial yields data showing that nitrate-rich beetroot juice alters the oral microbe composition and lowers blood pressure in older participants.

A new human trial provides evidence that nitrate-rich beetroot juice beneficially modifies the oral microbe composition and lowers blood pressure in older individuals.

Brain &amp; Neurons

Model: Primary hippocampal neurons from non-transgenic C57BL/6 (nTg) and triple-transgenic 3xTg-AD mice; age groups: young (2–6 mo), middle (8–11 mo), and old (17–28 mo).
Dosage: Nicotinamide 2 mM + EGCG 2 µM applied to cultured neurons for 16 h (in vitro).

Study shows that brief nicotinamide + EGCG treatment restores neuronal energy in 16–24 hours, restores autophagy, reduces amyloid-beta buildup, and boosts neuron survival by ~22% in aging/Alzheimer’s lab models.

Three types of beer, including IPA and stout, are shown to improve indicators of metabolic health in a mouse model for aging. 

Metabolism

Model: C57BL/6J mice, J20 mice, and 3xTg mice 
Dosage: 4.3 μEq l−1 of lithium in drinking water starting at 10 to 12 months of age and continued for 10 to 14 months during aging

Harvard Study: A Low Dose of Lithium May Preserve Cognitive Resilience with Age

Researchers uncover significantly lower brain lithium levels in Alzheimer’s disease patients, and supplementing with a low-dose lithium salt restores memory in an Alzheimer’s disease mouse model.

A Harvard study suggests lower levels of lithium in the brains of patients with Alzheimer’s disease and that lithium supplementation may help preserve cognitive resilience.

Participants: Healthy older adults 
Dosage: 1 mg/day of rapamycin for 8 weeks

Older adults taking low-dose rapamycin exhibit a reduction in senescent cells — cells that contribute to age-related diseases and a shorter lifespan.
