Ketones and longevity: Beyond the keto diet
Ketone bodies do far more than burn fat. Discover how BHB activates longevity pathways, fights inflammation, and slows biological aging — with or without a keto diet.
Hydration and biological aging: The NIH study that changed everything
A 30-year NIH study linked poor hydration with up to 50% higher odds of being biologically older. Learn the serum sodium thresholds, the science, and 7 strategies to stay optimally hydrated.
Mediterranean vs keto for longevity: Beyond weight loss
Mediterranean and keto diets both promise health benefits, but which one actually slows aging? Compare epigenetic evidence, autophagy data, and longevity research.
Vitamin D3 vs D2: What's the difference and which should you take?
Vitamin D3 vs D2 explained: learn the key differences in absorption, effectiveness, and sources. Plus, what VITAL and DO-HEALTH really show about vitamin D3 and aging.
How much protein do you need after 40? The science-based guide
Find out exactly how much protein you need after 40 to maintain muscle, boost metabolism, and stay strong. Science-backed recommendations by age and activity.
Magnesium glycinate vs citrate vs threonate: Which form should you take?
Compare magnesium glycinate, citrate, and threonate side by side. Learn which form is best for sleep, digestion, brain health, and how each one affects aging.
Intermittent fasting vs caloric restriction: Which is better for longevity?
Intermittent fasting and caloric restriction both extend lifespan in research. Discover which approach works better for longevity, weight loss, and metabolic health.
Magnesium and longevity: The mineral 31% of people get too little of (and why aging research cares)
31% of the global population and 48% of Americans get too little magnesium from food and beverages. Learn how magnesium connects to telomeres, mitochondria, DNA repair, inflammation, dosing, food sources, and testing.
Omega-3 and biological aging: The nutrient that slows your cellular clocks by nearly 4 months
A 2025 DO-HEALTH analysis found that 1g of omega-3 daily modestly slowed several epigenetic aging clocks. Discover the 6 anti-aging mechanisms of omega-3s, practical dosages, best food sources, and the evidence-based stack with vitamin D and exercise.
