Nutritional Supplements For Dogs And Cats

Nutritional Supplements for joints and calming,

Calming Supplements

L-theanine, L-tryptophan and alpha-clozapine are some of the ingredients commonly found in calming supplements for dogs.  L-theanine and L-tryptophan are amino acids that act as precursors for the synthesis of the neurotransmitter serotonin. Alpha-clozapine is a compound obtained from milk, which has calming properties in dogs and other animals.

L-theanine is marketed as Suntheanine®, Anxitane® and Composure®. Studies have shown that L-theanine has antidepressant effects in mice. It is used as a calming agent in dogs and cats, but there is minimal evidence documenting its efficacy, and this supplement is not FDA approved.

Experiments have shown that L-tryptophan supplementation decreases aggression in humans, dogs, pigs, poultry, and fish. This supplement may reduce fearfulness and stress in calves, vixens and poultry. However, behavioural characteristics more closely linked to the excitement, such as hyperactivity in dogs, are not modified by tryptophan supplementation.

Diets containing alpha-clozapine and L-tryptophan, such as Royal Canin “CALM”, improve the ability of an individual to cope with stress and may reduce anxiety-related behaviour in anxious dogs. Alpha-clozapine has also shown anxiolytic activity in laboratory experiments, but there are no clinical trials in dogs to confirm this

Fish Oil Supplements For Dogs And Cats

Treatment for cancer, joint, heart, kidney, skin and intestinal problems, as well as senior dementia, often include generous amounts of fish oil, which contain abundant amounts of DHA and EPA omega-3 fatty acids. Also, these oils have been shown to improve skin and coat quality. Overall, supplementing dogs and cats diets with fish oils is beneficial. However, there are some potential side effects when these supplements are used in excess.

Fish oils such as salmon oil, are rich in polyunsaturated fatty acids like omega-3. Omega-3 fatty acids include eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and alpha-linolenic acid (ALA). EPA and DHA are found in fish oils and have beneficial effects on the health of humans and pets. ALA is found in plants (e.g. flaxseed and canola oil), and it can be converted to EPA and DHA in the body. However, this conversion is not efficient in dogs and cats. For this reason, it is best to supplement dogs and cats diets with fish oils instead of plant oils.

Currently, omega-3 fatty acids are used in managing many diseases, including neoplasia, skin disease, hyperlipidemia, cardiovascular disease, renal disease, gastrointestinal disease, and joint disease. Also, these fatty acids are essential for brain function and development because there is a high concentration of omega-3 fatty acids in the brain.

Target ranges for EPA and DHA vary quite widely for different conditions but typically fall between 50 and 220 mg/kg of body weight per day. The higher dosages are to lower serum triglyceride concentrations in patients with high levels of triglycerides in the blood. In contrast, lower dosages used for inflammatory conditions, renal disease, and cardiac disease. 

High doses of omega-3 fatty acids may interfere with coagulation, wound healing and immune system function. Besides, an excessive quantity of omega-3 fatty acids can lead to gastric damage. The potential adverse effects of omega-3 fatty acids in dogs and include altered platelet function, gastrointestinal adverse effects, detrimental effects on wound healing, the potential for nutrient excess and toxic exposure, weight gain, altered immune function, impact on glycemic control and insulin sensitivity, and nutrient-drug interactions.


Joint Supplements for Dogs and Cats

The most commonly recommended supplements for the treatment of osteoarthritis are glucosamine, chondroitin sulphate and omega-3 fatty acids. Various research articles support the idea that these supplements are effective in decreasing clinical signs of osteoarthritis in dogs, such as pain and lameness.

Glucosamine and chondroitin are safe and the only side effects to be aware of are occasional diarrhoea and a remote possibility of blood clotting problems. If your pet is allergic to shellfish, you should not give glucosamine. Besides, high doses of glucosamine have been associated with increased urination frequency and increased water intake in dogs.
