Niacin improves organ function and survival following hemorrhagic shock. Rats and mice where bled 60% of their blood volume, and replaced with Ringers lactate solution to induce hemorrhagic shock ( deprive tissue of oxygen and blood ). After 10 minutes of shock the animals where split into 3 groups and injected with nicotinic acid, NMN or DMSO, at 3 levels of dosing. Niacin at 10mg/kg, which was the highest dose given, had by far the best level of survivability. Rats, given NMN even at a 5x higher dose than niacin at 50mg/kg did not achieve a survival rate to the level observed in the 10mg/kg or the even 5mg/kg treated mice. Use of GPR109A knockout mice confirmed that the niacin GPR109A receptor plays a major role in the survivability enhancing effect of niacin.
Nicotinamide mononucleotide (NMN) accumulation in the extra cellular environment contributes to the breakdown of axons (nerve fibers).
Most "niacin" products are niacinamide. If you want the form discussed in this research, look for nicotinic acid specifically.
