(Though you'll be able to tell from those happy tail wags) Turkey Dark Meat There is actually a reason why we decided to use Turkey and specifically the Dark Meat. Dark Meat contains higher levels of Taurine, in addition to being a valuable source of both Tryptophan and Niacin. While Tryptophan is commonly associated with serotonin and melatonin synthesis it is also an important precursor to Nicotinamide adenine dinucleotide (NAD) Which is a compound currently being widely research for its therapeutic benefits in a number of health conditions.
