{"product_id":"nad","title":"NAD+","description":"\u003cp\u003e\u003cspan style=\"font-weight: 400\"\u003eNAD⁺ (oxidized nicotinamide adenine dinucleotide) is a ubiquitous pyridine nucleotide coenzyme that accepts hydride ions in key metabolic pathways—glycolysis, the tricarboxylic acid cycle, and fatty-acid β-oxidation—to generate NADH for ATP production via oxidative phosphorylation. Beyond its redox role, NAD⁺ serves as an essential cosubstrate for NAD⁺-consuming enzymes such as sirtuin deacetylases and poly-ADP-ribose polymerases, thereby regulating gene expression, DNA-damage repair, and cellular stress responses. NAD⁺ availability also modulates mitochondrial biogenesis and metabolic homeostasis through SIRT1-PGC-1α signaling and impacts aging-related processes, as cellular NAD⁺ levels decline with age.\u003c\/span\u003e\u003c\/p\u003e","brand":"Alevia Store","offers":[{"title":"1000mg","offer_id":55842001092993,"sku":"NJ1000","price":112.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/7026\/6497\/files\/NAD-1000mg-2-scaled.webp?v=1782400646","url":"https:\/\/honest-peptides.ink\/products\/nad","provider":"Honest","version":"1.0","type":"link"}
