Daily Natural Support for Canine Cognitive Aging, Starting with the Antioxidant That Actually Gets Into the Brain.\nAstaxanthin at a guaranteed 0.52 mg per mL — one of the only natural antioxidants that crosses the blood-brain barrier and actually reaches brain tissue. Bacopa for memory and the chemical messengers mood and recall depend on. Ginkgo for blood flow to the brain. Eleuthero for the cellular energy an aging brain works harder to maintain.\n\n✓ 2 Certified Organic + 1 Wildcrafted + Natural Astaxanthin ✓ NASC Certified ✓ Crosses the Blood-Brain Barrier ✓ 0.52 mg Astaxanthin per mL · Guaranteed ✓ For Senior Dogs 7+ Years\n\n\n\n\nYou are watching your dog get a little more lost\nThey stand in the kitchen and look around like they have forgotten why they came in. They walk into the corner of the room and stop, facing the wall, unsure how to turn around. They wake at three in the morning and pace. They look at you a beat longer before responding to their name.\nThe dog who used to follow you from room to room now stays on their bed, watching you leave, not always remembering to get up and come along. The personality that has been yours for years is still there — but it takes a little longer to find now.\nThe veterinary term for what you are watching is canine cognitive dysfunction. By some estimates, around 28 percent of dogs aged 11 to 12 show signs of it, and over 60 percent of dogs aged 15 to 16 do. The biology behind it looks remarkably similar to what happens in the human brain with Alzheimer's: accumulated oxidative damage, slowing blood flow to the brain, declining chemical messengers, inflammation in brain tissue, and a specific protein that builds up between brain cells and interferes with communication.\n\nNo supplement reverses cognitive decline once it has set in, and we will not pretend otherwise.
