NAD⁺ (Nicotinamide Adenine Dinucleotide)

Mechanism of Action: Essential pyridine nucleotide coenzyme found in every living cell, existing in two forms: NAD⁺ (oxidized form) and NADH (reduced form). It serves as a critical electron transporter in cellular respiration and acts as a rate-limiting substrate for vital enzymes like sirtuins and PARPs.

Cellular Energy & Mitochondrial Function:

• ATP Production: Converts nutrients into cellular energy by driving electron transport in the mitochondria via the Krebs cycle and oxidative phosphorylation.

• Combating Cellular Fatigue: Restores depleted cellular energy reserves, optimizing metabolic output to alleviate physical and systemic fatigue.

Cognitive Function & Brain Health:

• Neuroprotection: Protects neurons from oxidative stress, excitotoxicity, and neurodegenerative decline by maintaining mitochondrial integrity in brain cells.

• Mental Clarity & Focus: Supports neurotransmitter synthesis and synaptic plasticity, improving processing speed, focus, and memory retention.

Anti-Aging & DNA Repair:

• Sirtuin Activation: Serves as the key substrate required to activate SIRT1–SIRT7 enzymes, which regulate gene expression, inflammation, and longevity pathways.

• DNA Damage Repair: Recruits PARP (Poly-ADP-ribose polymerase) enzymes to detect and repair single- and double-strand DNA breaks caused by environmental stressors and oxidative damage.

• Cellular Senescence: Helps slow down the accumulation of senescent (“zombie”) cells, promoting systemic tissue regeneration and youthfulness.
