Certified Peptides NAD+: plain or buffered?

Certified Peptides NAD+ comes as a plain 500mg vial and as buffered NAD+ in 500mg and 1000mg. This guide explains the difference, what NAD+ does in the cell and how to mix it.

What is Certified Peptides NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme in every living cell. It carries electrons in energy metabolism and is a substrate for sirtuins and PARPs. Its levels drop with age in many tissues.

Our NAD+ is freeze-dried powder in a glass vial, made in the USA and tested batch by batch.

Plain NAD+ 500mg is the classic research format. Buffered NAD+ 500mg and 1000mg add a buffer so the mixed solution sits closer to neutral pH, which some labs prefer for cell work. The Mito blend pairs NAD+ with 5-Amino-1MQ and MOTS-c.

How NAD+ works

NAD+ shuttles electrons in glycolysis, the Krebs cycle and the mitochondrial chain, so it’s needed to turn food into ATP. It’s also used up by sirtuins, which regulate gene expression, and by PARPs, which repair DNA.

Because those enzymes consume it, NAD+ levels depend on constant recycling. Falling levels with age are linked to lower sirtuin activity, which is the basis for most NAD+ aging research.

NAD+ research

Reviews by Imai and Guarente, and by Verdin, cover the link between falling NAD+ and aging. Precursors like NR and NMN have been tested in small human trials. Start with this PubMed search on NAD+ and aging.

Mixing and storing Certified Peptides NAD+

NAD+ dissolves readily in bacteriostatic water. A 500mg vial with 5mL gives 100mg/mL. Swirl, don’t shake, since shaking only adds foam. Store sealed vials cold and dry, and keep mixed vials in the fridge.

How Certified Peptides NAD+ is tested

Every batch is made in the USA and tested by an independent U.S. lab: identity by mass spectrometry, content, and purity by high-performance liquid chromatography (HPLC) to a 99%+ standard, plus endotoxin, heavy metal and sterility screens. On most products the report for the batch in stock is in the photo gallery.

Certified Peptides NAD+ FAQ

What is buffered NAD+?

NAD+ with a buffer added so the mixed solution sits closer to neutral pH. Plain NAD+ makes a fairly acidic solution.

Which Certified Peptides NAD+ sizes are there?

NAD+ 500mg ($68), buffered NAD+ 500mg ($90) and buffered NAD+ 1000mg ($130).

Do you sell NAD+ in a blend?

Yes. The Mito blend has 50mg NAD+ with 5-Amino-1MQ and MOTS-c, and one capsule formula includes 100mg NAD+.

Is NAD+ for human use here?

No. Ours is sold for laboratory research only.
