NAD+ Powder in Bulk: Purity, Stability and What Supplement Manufacturers Should Check

NAD+ (nicotinamide adenine dinucleotide) is one of the most requested ingredients in the healthy-ageing supplement category. For manufacturers, the challenges are purity, moisture sensitivity and consistent documentation across batches.

Purity and identity

Specify purity by HPLC with the method named, and identity by HPLC retention and spectroscopy. Red Chem Biotech supplies NAD+ at a minimum of 99.0% HPLC purity with a batch Certificate of Analysis.

Moisture, stability and packaging

• NAD+ is hygroscopic: specify a water content limit
• Ask for the retest period and the storage conditions that support it
• Require sealed, moisture-protected packaging, and store cool and dry on arrival

Contaminant tests supplement makers need

• Heavy metals or elemental impurities
• Microbial limits (total aerobic count, yeasts and moulds, absence of specified pathogens)
• Residual solvents

NAD+ versus its precursors

• NAD+: the coenzyme itself
• NMN and NR: precursors converted to NAD+ in the body
• NMNH: the reduced form of NMN

Each is a separate material with its own specification; do not substitute one for another without reformulating.

Ordering in bulk

NAD+, NMNH, glutathione and urolithin A are available in bulk from 1 kg with specification, COA and SDS. See the price per kilogram on each product page and request a quote online.
