What is choline?
Choline (brand name Cholodin®) is a vitamin that is used in detoxification pathways in the liver and as a precursor to nervous system chemicals such as acetylcholine and dopamine. Because of these effects, supplemental choline is used in dogs and cats with seizures and/or cognitive dysfunction.
Dietary supplements are substances that can be used to supplement the diet, such as vitamins, minerals, amino acids, herbs, botanicals, enzymes, and probiotics. While many supplements are sold over the counter, they still contain ingredients that have biological effects that should be managed by your veterinarian. Follow your veterinarian’s directions and cautions very carefully as their directions may be significantly different from those on the label.
There are differences in how countries regulate supplements. In the United States, these substances are not as vigorously regulated by the FDA as other medications, which means they can be sold without the manufacturer proving their effectiveness, safety, and without a guarantee of consistent or accurately reported ingredients. In Canada, products that have been evaluated for quality, safety, and effectiveness by Health Canada and authorized for sale will have a license number on the label.

What if I miss giving my pet the supplement?

- give the missed dose and then wait the recommended interval before giving the next dose (continue giving it regularly at that new time).
