As dogs age, their cognitive function can decline, leading to issues such as memory loss, confusion, and decreased alertness. Fortunately, natural supplements can support canine brain health and help maintain mental sharpness well into old age. Below are nine natural supplements that can promote cognitive function and overall brain health in senior dogs.

Omega-3 Fatty Acids

Omega-3 fatty acids, particularly DHA and EPA, are essential for brain function and cognitive health. They help reduce inflammation and support neural function, making them beneficial for aging dogs. iHeartDogs Norwegian High Omega-3 Salmon Oil (On Amazon) is an excellent source of high-quality omega-3s that can support brain health and overall well-being.

Glucosamine and Turmeric

While commonly known for their joint health benefits, glucosamine and turmeric also support cognitive function. Turmeric contains curcumin, a powerful antioxidant with anti-inflammatory properties that may help protect brain cells. Glucosamine and Turmeric Chews (On Amazon) provide an easy and tasty way to incorporate these brain-boosting ingredients into your dog’s diet.

Antioxidants

Antioxidants help combat oxidative stress, which can contribute to cognitive decline in aging dogs. Ingredients like blueberries, vitamin E, and green tea extract are rich in antioxidants and can support brain health by reducing free radical damage.

Phosphatidylserine

Phosphatidylserine is a vital component of cell membranes and plays a crucial role in cognitive function. Studies suggest that supplementing with phosphatidylserine can help improve memory and learning in senior dogs, making it an important addition to their diet.

B Vitamins

B vitamins, particularly B6, B9 (folate), and B12, support brain health by aiding in neurotransmitter function and reducing homocysteine levels, which can contribute to cognitive decline. Ensuring that senior dogs receive adequate B vitamins can help maintain their mental sharpness.

Medium-Chain Triglycerides (MCTs)

MCTs, found in coconut oil, provide an alternative energy source for the brain and have been shown to enhance cognitive function in aging dogs. Adding MCTs to your dog’s diet may help improve their alertness and overall mental function.

Ginkgo Biloba

Ginkgo biloba is a well-known herbal supplement that supports circulation and cognitive function. It may help enhance memory and reduce age-related cognitive decline in senior dogs.

L-Carnitine

L-Carnitine is an amino acid that supports energy metabolism in brain cells. It has been shown to improve cognitive function and may help aging dogs stay mentally active and engaged.

Senior-Specific Brain Support Supplements
