What Happens If a Dog Eats Human Vitamins?

Assuming you’re referring to vitamin supplements that are intended for human consumption: If a dog ingests vitamins meant for human consumption, it is possible that the dog may experience health problems. This is because vitamins are regulated differently for humans and animals.

The United States Food and Drug Administration (FDA) regulates vitamins for human use, while the United States Department of Agriculture (USDA) regulates vitamins for animal use. The FDA has established Recommended Daily Intakes (RDIs) for various vitamins, which are the levels of intake that are sufficient to meet the needs of 97-98% of healthy people. The RDIs are based on scientific studies that have looked at the effects of different levels of vitamin intake on human health.

In contrast, there are no RDIs established for dogs or other animals. This means that if a dog ingests human vitamins, it may be getting too much or too little of certain nutrients. In some cases, this can lead to vitamin toxicity or deficiency.

For example, if a dog ingests too much vitamin A from human supplements, it may experience joint pain, muscle weakness, and changes in vision and behavior. If a dog doesn’t get enough vitamin E from its diet, it may develop heart disease or neurological problems.
