<p><span style="font-weight: 400;">Model: C57BL/6J mice </span></p>
<p><span style="font-weight: 400;">Dosage: Eating only within an 8-hour window and fasting for 16 hours (~20% caloric deficit may be required) </span></p>


Restricting food intake for 16 hours a day improves the health of female mice and moderately prolongs the life of male mice.

Aging &amp; Longevity

New Framework Uncovers 21 Existing Drugs with Pro-Longevity Potential

A new gene network-based framework predicts the potential of existing drugs to confer pro-longevity effects.

A new gene network-based framework predicts already-approved repurposable drugs that may either confer pro-longevity benefits or age-accelerating effects.

<p><span style="font-weight: 400;">Model: SAMP8 mice </span></p>
<p><span style="font-weight: 400;">Dosage: ~25 mg/kg/day of PQQ or PQI administered in food </span></p>


Supplementing with the antioxidant pyrroloquinoline quinone (PQQ) modestly extends the lifespan of age-accelerated mice while improving their strength.

Dasatinib and Quercetin Delay Early-Onset Disc Degeneration in Mice

Researchers find that clearing senescent cells preserves disc structure and slows early-onset disc degeneration in mice.


<p><span style="font-weight: 400;">Model: 5xFAD mouse model for Alzheimer’s disease </span></p>
<p><span style="font-weight: 400;">Dosage: Oral administration of 457 mg/kg/day of glucosamine for 2 weeks </span></p>


Supplementing with glucosamine, a compound found in our cartilage, increases the risk of mortality from dementia in certain individuals while also worsening memory in mice that model dementia.
