====Pyridoxine====

Pyridoxine (vitamin B6) is a cofactor in the production of serotonin, and there is evidence that supplementation can alter tryptophan metabolism to produce higher central nervous system (CNS) levels of 5-hydroxytryptophan and serotonin in studies involving laboratory animals<ref>Calderón-Guzmána, D., Hernández-Islasa, J.L., Espitia-Vázqueza, I., Barragán-Mejı́aa, G.,  Hernández-Garcı́aa, E., Santamarı́a-del Ángela, D., Juárez-Olguı́nb, H. (2004) Pyridoxine, regardless of serotonin levels, increases production of 5-hydroxytryptophan in rat brain. Archives of Medical Research. 35(4).271–274.</ref>. However, the specific effects of this vitamin alone on behaviour in cats and dogs has not been established. Caution should be exercises regarding pyridoxine dose, given that it is potentially neurotoxic in overdose<ref>Rao, D.B., Jortner, B.S., Sills, R.C. (2014) Animal models of peripheral neuropathy due to environmental toxicants. ILAR J. 54(3):315-23.</ref>.

====Fatty Acids====

For cats, cis-linoleic and arachidonic acid are essential fatty acids. However, other fatty acids, specifically long-chain omega-3 fatty acids such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for normal development<ref>Innis, S.M. Dietary (n-3) fatty acids and brain development. J Nutr 2007:137:855-9</ref>.  DHA and EPA have been shown to have anti-inflammatory effects<ref>Serini, S., Bizzarro, A., Piccioni, E., Fasano, E., Rossi, C., Lauria, A., Cittadini, A.R., Masullo, C., Calviello, G. (2012) EPA and DHA differentially affect in vitro inflammatory cytokine release by peripheral blood mononuclear cells from Alzheimer's patients.

J Nutr Biochem. 18(4):250-8.</ref><ref>Mullen, A., Loscher, C.E., Roche, H.M.

There is evidence that higher levels of DHA in puppy diets produce improved cognitive performance in laboratory tests (reversal task learning, visual contrast discrimination, and early psychomotor performance)<ref> Zicker, S.C, Jewell, D.E., Yamka, R.M., et al. Evaluation of cognitive learning, memory, psychomotor, immunologic, and retinal functions in healthy puppies fed foods fortified with docosahexanoeic acid-rich fish oil from 8-52 weeks. J Am Vet Med Assoc 2012;241:583-94</ref>, and are essential for normal retinal function<ref>Bauer, J.E., Heinemann, K.M., Lees, G.E., et al. Retinal functions of young dogs are improved and maternal plasma phospholipids are altered with diets containing long-chain n-3 polyunsaturated fatty acids during gestation, lactation, and after weaning.
