The science of aging well. Research on NAD+ supplementation, cellular repair, telomere health, mitochondrial function, and anti-aging protocols designed to extend healthspan and optimize long-term vitality.
MMP-1 and MMP-9 are zinc-dependent enzymes that UV radiation activates within hours of sun exposure, cleaving type I and type III collagen and accelerating dermal aging. Understanding TIMP regulators and copper peptide modulation reveals why some interventions reverse photoaging while others fail.
Matrikines are peptide fragments liberated from collagen, elastin, and laminin during extracellular matrix turnover. Unlike growth factors, they directly instruct fibroblasts to remodel tissue — making them a foundational target in dermal aging therapy.
Magnesium is not just a generic mineral — it is the voltage-dependent plug inside every NMDA receptor. When intracellular Mg²⁺ falls, the gate fails, glutamate becomes excitotoxic, and synaptic plasticity collapses.
Magnesium isn't just a generic mineral — it's the voltage-dependent gatekeeper of NMDA receptors. Intracellular Mg²⁺ depletion drives excitotoxicity, impaired LTP, and accelerated cognitive decline.
Oral NMN, oral NR, and direct NAD+ infusion produce strikingly different tissue distributions. Understanding the Slc12a8 transporter and first-pass metabolism explains why route of administration — not just dose — determines which organs actually see an NAD+ rise.
The route of administration — oral NMN, oral NR, or parenteral NAD+ — dramatically changes which tissues actually receive NAD+ precursor uplift. Pharmacokinetics, not dose, often determines clinical outcome.
AMPK is the master energy-sensing kinase that switches cells from anabolic storage to catabolic fat oxidation. Research links its activation to improved insulin sensitivity, autophagy, and healthspan.
Injectable NAD+ combined with B12 represents the gold standard for cellular energy restoration. Learn about mechanisms, research, what to expect, and why physician oversight matters.
NAD+ is essential for cellular energy and longevity. Compare nasal spray delivery vs. IV drip therapy — cost, convenience, bioavailability, and what the research supports.
