Nicotinamide riboside tartrate (NRT) is an oral NAD+ precursor that raises NAD+ levels, activates SIRT1 and SIRT3, and serves as a vitamin B3 (niacin) source. NRT also improves oxidative metabolism and protects against metabolic abnormalities induced by a high-fat diet. Furthermore, NRT mitigates cognitive decline in a transgenic mouse model of Alzheimer's disease.

Nicotinamide riboside malate is an orally active NAD+ precursor that elevates NAD+ levels and stimulates the activity of SIRT1 and SIRT3. Functioning as a vitamin B3 (niacin) source, it augments oxidative metabolism and provides protection against metabolic abnormalities induced by a high-fat diet. Additionally, Nicotinamide riboside malate mitigates cognitive decline in a genetically modified mouse model of Alzheimer's disease.

Nicotinamide Riboside Triflate (SRT647 Triflate) is a natural NAD precursor that increases NAD levels, enhances oxidative metabolism and prevents obesity induced by a high-fat diet+, and can be used in studies of muscle atrophy.

Nicotinamide riboside chloride, also known as NR and SRT647, is a pyridine-nucleoside form of vitamin B3 that functions as a precursor to nicotinamide adenine dinucleotide or NAD+.

Nicotinamide riboside increases NAD[+] levels and activates SIRT1 and SIRT3, culminating in enhanced oxidative metabolism and protection against high fat diet-induced metabolic abnormalities.
