Differences Between NR, Niacinamide, and NMN
- Molecular structures and chemical compositions differ.
NR is a vitamin B3 variant akin to Niacinamide, while NMN is a nucleotide derived from ribose and nicotinamide. These variances affect how they work in NAD+ production.
- NR chemical formula: C11H15N2O5
- Niacinamide chemical formula: C6H6N2O
- NMN chemical formula: C₁₁H₁₅N₂O₈P
- Bioavailability and absorption rates vary.
NR bioavailability and absorption
NR is well-absorbed in the gastrointestinal tract, allowing it to enter the bloodstream and be transported to various tissues.
After absorption, NR is converted into NAD+, a coenzyme involved in cellular energy production and other metabolic processes. This conversion occurs through a series of enzymatic reactions in the body.
Once converted to NAD+, Nicotinamide Riboside is distributed throughout the body, reaching various organs and tissues.
The conversion of NR to NAD+ is mediated by specific enzymes, such as nicotinamide riboside kinases (NRKs). The activity of these enzymes can influence the efficiency of NR conversion and subsequent NAD+ synthesis.
Niacinamide bioavailability and absorption
Niacinamide is a water-soluble compound, allowing it to dissolve easily in the aqueous environment of the digestive system.
Once absorbed, it undergoes rapid conversion to its active form NAD+ or its phosphorylated form NADP+.
Unlike other forms of niacin, Niacinamide is not metabolized in the liver to the same extent. As a result, it does not cause the flushing or skin reactions commonly associated with niacin supplementation.
Niacinamide is excreted primarily through urine, with a small portion eliminated in feces.
NMN bioavailability and absorption
One thing to notice is that NMN is less stable in the digestive system and requires additional steps for conversion to NAD+.
Specific enzymes, such as nicotinamide phosphoribosyltransferase (NAMPT), mediate the conversion of NMN to NAD+. The activity of these enzymes can impact the efficiency of NMN conversion and subsequent NAD+ synthesis.
- Ingredients safety and recommended dosages also diverge.
Nicotinamide Riboside has been generally regarded as safe with minimal reported side effects.
Studies and clinical trials have shown no significant adverse reactions at recommended dosages. The typical daily doses of NR range from 200 to 500 milligrams.
Niacinamide powder is considered safe and well-tolerated as a supplement ingredient to support NAD+ levels. It carries a low risk of side effects. And this ingredient is available in different forms like capsules, tablets, and creams. The recommended dosages generally range from 500 to 1000 milligrams per day.
On November 4, 2022, the FDA stated that NMN may not be sold as a supplement and is under investigation as a drug.
