Ivers and Veum found that among the doses used (6, 10, 14, 18, 22 and forty four mg/kg food regimen with sufficient Trp), 14 mg of niacin/kg produced maximum weight gain in rising pigs. Shibata et al studied the impact of nicotinamide at doses of zero, 60, a thousand and 5000 mg/kg food plan on rat weight gain. Their result confirmed that nicotinamide elevated the meals consumption of rats, especially within the teams fed food plan containing 60 and a thousand mg/kg of nicotinamide. The highest weight acquire was noticed at 60 mg/kg, while excessive-dose nicotinamide (5000 mg/kg diet) led to an inhibition of weight achieve on the early stage of publicity because of its toxicity. These animal studies suggest that the supplemental dose for niacin to attain maximum weight-achieve effect may be round or lower than 60 mg/kg diet.
