NAD+ Biology and Aging: Expert Insights on Boosting NAD Levels
NAD is genuinely important for cellular function, but the popular claim that "NAD declines with age" in healthy people is overstated—disease and metabolic problems are more reliable drivers of NAD …
High-Dose Creatine for Brain Function: 2024 Study Breakdown and Dosing Insights
While this post cites real creatine research and legitimately debunks safety myths, the recommendation to increase dosing to 15-20g/day for cognitive benefits lacks sufficient peer-reviewed support and exceeds conventional safety …
What Blood Biomarkers Predict Living to 100? Insights from Swedish Centenarian Study
A high-quality Swedish study found that certain blood biomarker patterns in middle age—including higher cholesterol and iron, lower blood sugar and kidney markers—were associated with living to 100, but this …
1,500 Days Sober: Biomarkers Show Dramatic Health Recovery After Alcoholism
This is an inspiring personal recovery story with impressive current biomarkers, but the dramatic health improvements cannot be scientifically proven without before/after data, comparison groups, and independent lab verification. The …
Genetics May Account for 50% of Lifespan, New Study Suggests
While the genetic contribution to lifespan is a legitimate research question, this post cites an unverifiable study without sufficient detail to evaluate its claims. Readers should be cautious about the …
Life Expectancy Gains Are Slowing—Here's Why
Life expectancy improvements in wealthy countries are genuinely slowing because we've nearly eliminated infant and childhood deaths—the easy wins of the 20th century. Future improvements will require new medical breakthroughs …
DMTF1 Gene May Reverse Brain Aging in Neural Stem Cells
Researchers found a gene (DMTF1) that may help aging brain stem cells divide better by controlling chromatin structure, offering a potential drug target—but this is early-stage cellular research with no …
Horvath's Epigenetic Clocks: Measuring and Reversing Aging
Horvath's epigenetic clocks are real, peer-reviewed scientific tools that can measure biological age—a genuine advance in aging research. However, this discussion lacks evidence that measuring aging translates to reversing it, …
Does Ginseng Slow Aging? A Small Study on Telomeres and Cellular Energy in Middle-Aged Adults
Ginseng showed associations with longer telomeres and better aging markers in this small uncontrolled study, but without a placebo group or independent replication, these findings are preliminary and could reflect …
How Mild Calorie Restriction Rewires Brown Fat to Stay Energetic
Mild calorie restriction rewires brown fat to work more efficiently—not by burning out, but by adapting its metabolism while preserving its heat-generating power. This is a mechanistic clue about why …
How aging immune cells drive aging throughout the body
This is an authoritative but not definitive review explaining why your immune system's aging is a central driver of whole-body aging—and why fixing it could be unexpectedly powerful for extending …
Can crocin-enriched tomatoes slow aging and protect the brain?
This fruit fly study suggests crocin-enriched tomatoes may protect aging brains by supporting mitochondria, but much more work—especially human studies—is needed before we can say whether eating these tomatoes will …
