Gingko BilobaGingko is an herbal supplement derived from the leaves of the Gingko Biloba tree. The leaves can stimulate blood flow to the extremities and to the brain – therefore it is used to treat cognitive dysfunction and memory problems. Widespread animal studies describe Gingko as having antioxidant properties capable of providing protective effects during conditions of oxidative stress. Oxidative stress is especially harmful to the brain tissue, which can lead to cognitive decline. |
DHADocosahexaenoic Acid (DHA) is a long-chain, polysaturated fatty acid. DHA is a primary structural component of nerve, eye, and brain tissue, and is crucial for their proper development and function. Decreases in DHA in the brain are associated with cognitive decline, which is a great reason why you should supplement your aging dogs pet food to make sure they are getting all of the nutrients they need. |
Vitamin B-6Vitamin B-6 is a water-soluble vitamin that is stable to heat and acid. However, oxidation or exposure to alkali or UV light can destroy it, and as much as 50% of Vitamin B-6 is destroyed during cooking and processing. All the B vitamins benefit the brain, but B-6 is especially important for regulating moods and preventing mental fatigue. This water-soluble vitamin is needed for the brain to produce serotonin and it helps the body make hemoglobin – the part of your blood that carries energy-boosting oxygen to the brain and other organs. |
PhosphatidylcholinePhosphatidylcholine (PC) plays an essential role in the overall health of all dogs and cats. Typical food sources of PC include egg yolks, soy lecithin, red meats, sunflower seeds, liver and spinach. Very little PC is found in typical pet food offerings, thus making supplementation quite beneficial. Primary benefits of PC supplementation include enhancing memory, improving brain function, slowing cognitive decline, and has also been used to protect the liver from the accumulation of fat and cholesterol. |
