Nicotinamide Riboside

nucleoside · endocrine · musculoskeletal · Oral

Nicotinamide Riboside, a nucleoside. NAD⁺ precursor — enters cells via ENT transporters, phosphorylated to NMN by NRK1/2, then adenylated to NAD⁺… Oral half-life 1 h.

NAD⁺ precursor — enters cells via ENT transporters, phosphorylated to NMN by NRK1/2, then adenylated to NAD⁺ by NMNAT. Smaller than NMN (no phosphate) so better cell entry. Raises whole-blood NAD⁺ ~40–60% at 300 mg/d in published RCTs.

PK: THE STORED VOLUME WAS THE SOLVER DEFAULT WEARING A CITATION. 35 L is exactly 0.5 L/kg at the seventy-kilogram reference — the value resolvePk substitutes when the field is ABSENT — and this record cited abstract states no volume at all. Removing it is NUMERICALLY A NO-OP, since the resolver now supplies the identical number; what changes is that the record stops asserting a measurement it does not have, and the defaulted-volume lint begins counting it as the open gap it is. This is the batch-11 finding running backwards: there a deletion silently became a default, here a default had silently become a datum.
