NAD+ 500mg

NAD+ Peptides are small chains of amino acids that facilitate the transfer of nicotinamide adenine dinucleotide (NAD+) within cells. As a crucial coenzyme, NAD+ plays a vital role in supporting mitochondrial activity and cellular metabolism, which are key to maintaining cellular energy levels. By activating sirtuins, these peptides contribute to DNA repair and promote longevity by mitigating the effects of NAD+ decline associated with aging. Packaged in vials containing 500mg, these peptides are intended for those focused on wellness and healthy aging, providing support for cellular repair processes.

NAD+ and NMN (Nicotinamide Mononucleotide) are closely related but represent different approaches to cellular NAD+ support in research. NAD+ is the active coenzyme itself — supplying it directly is studied for rapidly restoring intracellular NAD+ levels, particularly in contexts where NAD+ synthesis capacity is compromised. NMN is a biosynthetic precursor to NAD+ — it must be converted to NAD+ inside the cell via the Preiss-Handler or salvage pathway before becoming metabolically active. Research comparing the two examines bioavailability, tissue-specific uptake, conversion efficiency, and which approach more effectively restores NAD+ in aged or metabolically stressed cells. Both are studied in longevity and metabolic aging research, often by the same research groups examining different supplementation strategies.

NAD+ and Glutathione are both studied for cellular protection and healthy aging but operate through entirely different mechanisms. NAD+ is an electron carrier and enzyme substrate — its role is in energy metabolism, DNA repair via PARPs, and longevity signaling via sirtuins. Glutathione is the cell's primary antioxidant — it directly neutralizes reactive oxygen species and supports liver detoxification. NAD+ depletion is associated with mitochondrial dysfunction and aging; Glutathione depletion is associated with oxidative damage and immune compromise. Researchers studying cellular energy and metabolic aging tend to focus on NAD+; those studying oxidative stress and detoxification tend to focus on Glutathione. Both are available at Peptides Costa Rica — Glutathione 1500mg is priced at ₡46,000.

NAD+ (Nicotinamide Adenine Dinucleotide) is studied for its role as the central electron carrier in mitochondrial energy metabolism (ATP production via oxidative phosphorylation); substrate for sirtuin enzymes (SIRT1–SIRT7) involved in gene expression regulation, metabolic adaptation, and longevity signaling; substrate for PARP enzymes involved in DNA damage detection and repair; substrate for CD38 involved in calcium signaling and immune function; and neuroprotection and cognitive function support through NAD+-dependent neuronal energy maintenance. NAD+ decline with age is one of the most studied hallmarks of cellular aging.

NAD+ and NADH are the oxidized and reduced forms of the same molecule. NAD+ (the oxidized form) accepts electrons during cellular metabolism — particularly in glycolysis and the Krebs cycle — becoming NADH (the reduced form). NADH then donates those electrons to the mitochondrial electron transport chain, driving ATP synthesis and reverting to NAD+. The NAD+/NADH ratio is a key indicator of cellular redox state and metabolic health. Research peptide suppliers provide NAD+ (the oxidized form) as it is the enzyme substrate form — the version that activates sirtuins, PARPs, and other NAD+-consuming enzymes relevant in aging and repair research.

NAD+ 500mg at Peptides Costa Rica is priced at ₡52,734 per vial, in USD. With a 15% bulk discount on orders of five or more vials, the per-vial cost drops to ₡45,356 — a saving of ₡40,020 on a five-vial order (₡266,800 down to ₡226,780). Pairing a single vial with BAC Water or another compound crosses the ₡92,000 free-shipping threshold for free Costa Rica delivery.

Unreconstituted NAD+ vials should be stored refrigerated at 2–8°C in lyophilized (powder) form, protected from light and moisture. NAD+ is sensitive to heat and humidity degradation — avoid leaving vials at room temperature for extended periods. Freezing is suitable for long-term storage. Once reconstituted with bacteriostatic water, keep the solution refrigerated, minimize light exposure, and use promptly — reconstituted NAD+ is less stable than the lyophilized form and should not be stored for extended periods after reconstitution.

Orders inside Costa Rica are typically delivered within 2–4 business days. You'll receive tracking once shipped — no customs delays or import fees since everything is fulfilled domestically.
