Longevity is no longer exclusive. Research-led ingredients, clear formulas, and practical daily use bring science-led healthy aging within reach.
NMN sits immediately upstream of NAD⁺ in the cellular salvage pathway. NMN adenylyltransferase (NMNAT) transfers an adenylyl group from ATP to NMN, forming NAD⁺. The resulting coenzyme participates in cellular energy metabolism and serves enzymes involved in maintenance and signaling. This defined biochemical step is the rationale for studying NMN as an NAD⁺ precursor.
In an Abinopharm-affiliated randomized trial, 80 healthy middle-aged adults received placebo or one of three daily doses of AbinoNutra™ NMN for 60 days. Blood NAD concentrations were measured at baseline, day 30, and day 60; all three NMN groups rose relative to placebo. A later analysis of the same trial examined dose response and variation between participants.
NR supplies a precursor for NAD⁺ production. L-Ergothioneine follows a different route: the selective SLC22A4 transporter carries it into cells, where its stable thione chemistry helps buffer reactive species. Pairing the two brings NAD⁺ metabolism and antioxidant protection into the same daily formula without treating ergothioneine as another NAD⁺ precursor.
Dr.Ergo® is Abinopharm’s branded L-Ergothioneine, produced through licensed full-enzymatic natural fermentation technology developed by the Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences. Production takes place in an NSF cGMP- and HACCP-certified facility, with each batch tested against predefined specifications for identity, chemical and optical purity, residual solvents, heavy metals, and microbial limits.
NR Starter provides 500 mg of nicotinamide riboside, a form of vitamin B3 used in the NAD⁺ salvage pathway. Nicotinamide riboside kinase converts NR to NMN; NMN adenylyltransferase then converts NMN to NAD⁺.
This defined sequence gives NR its central role in the formula: it supplies starting material for the body’s own NAD⁺ production rather than acting as a general stimulant.
Sunflower lecithin is a phospholipid-rich formulation component used in the NR Starter complex. Its amphiphilic molecules interact with both water- and fat-associated materials, helping disperse and organize the accompanying actives.
Its role is physical and formulation-led: sunflower lecithin supports the delivery system while NR remains the formula’s NAD⁺ precursor.
Resveratrol is a plant-derived polyphenol included in the NR Starter supporting complex. It is studied for its interactions with cellular stress-response and metabolic signaling pathways.
Within this formula, resveratrol has a supporting role distinct from NR: it broadens the polyphenol and antioxidant profile without serving as an NAD⁺ precursor.
Quercetin is a flavonoid found naturally in many fruits and vegetables. In NR Starter, it contributes a second plant-derived component to the formula’s antioxidant-focused supporting complex.
Quercetin does not replace or duplicate NR. It is included for a separate supporting function alongside resveratrol and Dr.Ergo® L-Ergothioneine.
