Six things worth checking on any research-chemical order, and what you get here versus what the category typically does.
Provyd
Aluminium crimp seal intact and unbroken, stopper embossed. A seal that arrives compromised is grounds for replacement.
Typical research-chemical vendor
Loose or re-crimped caps are common, with no stated policy if the seal arrives broken.
Describes common practices in the research-chemical category, not any specific company. Provyd performs no independent or third-party testing, and all documentation referenced is supplied by the manufacturer.

State of the evidence
Human randomized controlled trial data available for oral nicotinamide and for the NAD+ precursors nicotinamide riboside and nicotinamide mononucleotide; trials are generally small and short-duration apart from nicotinamide skin-cancer chemoprevention. Intravenous NAD+ itself has minimal controlled human trial data.

A Phase 3 Randomized Trial of Nicotinamide for Skin-Cancer Chemoprevention
Chen AC, et al.
In the ONTRAC trial, oral nicotinamide 500 mg twice daily reported a 23% lower rate of new nonmelanoma skin cancers at 12 months versus placebo, with no benefit evident after discontinuation.
- Human clinical trialScience · 2021
Nicotinamide mononucleotide increases muscle insulin sensitivity in prediabetic women
Yoshino M, et al.
In a 10-week randomized placebo-controlled trial in postmenopausal women with prediabetes who were overweight or obese, nicotinamide mononucleotide increased insulin-stimulated glucose disposal measured by hyperinsulinemic-euglycemic clamp and increased skeletal muscle AKT and mTOR phosphorylation, with no change in the placebo group.

Chronic nicotinamide riboside supplementation is well-tolerated and elevates NAD+ in healthy middle-aged and older adults
Martens CR, et al.
In a 2 x 6-week randomized double-blind placebo-controlled crossover trial, oral nicotinamide riboside was well tolerated and stimulated NAD+ metabolism in healthy middle-aged and older adults.

Nicotinamide Riboside Augments the Aged Human Skeletal Muscle NAD+ Metabolome and Induces Transcriptomic and Anti-inflammatory Signatures
Elhassan YS, et al.
In 12 aged men given 1 g nicotinamide riboside daily for 21 days in a placebo-controlled crossover trial, the skeletal muscle NAD+ metabolome was elevated and circulating inflammatory cytokines decreased, without altered mitochondrial bioenergetics.
