Human Vitamins and Supplements for Dogs – How Safe Are They?

Human vitamins and supplements for dogs. Hmmm…sounds rather contradictory, doesn’t it? But as time marches on, dog experts and veterinarians are accepting this unique relationship regarding humans and dogs. They also make it a priority to point out vitamin and supplementary issues with toxicity if not handled properly.

As we know, human vitamins and supplements are designed for people, while dog vitamins and supplements are for dogs. Dog and human vitamins and supplements for dogs provide the boost that their body needs or to supplement what their body is lacking, as in people.

Sometimes we think to ourselves, “Are these mineral supplements beneficial for our best friends?” The best way to find out is to go to the good ole’ family vet and thoroughly discuss their opinion on the subject of human vitamins and supplements for dogs.

  • Does your dog need them?
  • Discuss how beneficial they would be for your dog.
  • Discuss their safety and possible side effects.
  • Will they make your dog more active and robust?
  • What are the best human supplements currently being given to dogs?

Make sure your vet tells you how to cut down on the dosages or how to convert the meds on the directions. Understand medical terminology, or it could be very easy to over-medicate your dog without even knowing it.

Vitamins and minerals help in daily activities

It is now possible for these same human supplements to help our beloved dogs. Strenuous processes within the bodies of our K9 friends, hard at work in their various fields, require dog supplements helps them maintain physical health and maximum energy. If used correctly, they also shield dogs from the harmful elements that we, dogs and masters alike, face when we are going for a walk in the middle of winter or for working dogs herding cattle all day.

Pollutants, excessive heat and cold, and toxins abound in the open world

Vitamins and supplements keep us strong and active when our system is lacking in adequate health due to what is around us. Our pets can benefit in the same way from vitamins and supplements for dogs. But what is good for us may not be suitable for our best friends; a human supplement can prove disastrous if given unknowingly of its effects to dogs. For example, human vitamins A, E, K, and D are poisonous to pets for their fat soluble properties. Medications for upper respiratory tracts and weight loss medicines lower the dog’s heart rate which puts your dogs in peril.

Human vitamins and supplements for dogs are not acceptable!

Up until now, human supplements were thought to be for humans only. And the fact is, body weight and mass are entirely different between people and dogs. And, some can be quite dangerous for dogs as there is a significant difference between dog vitamins and supplements as compared to human vitamins and supplements. 

The age old theory that human vitamins and supplements are not for dogs has gone out the window. But this does not mean care is not necessary when giving the human version to your dog. 

When Vitamins A, E, K, and D enter a dogs’ system, they are stored in the body

Primary vitamins are A, E, K, D, and B, are not a problem.  Referred to as organic compounds and vital nutrients, they are not an issue for dogs either if they are absorbed in small doses.  But these same compounds are called vitamins when they are unable to be absorbed into a dog’s body.

These compounds are called a vitamin when your dog cannot synthesize the substance in sufficient quantities and must therefore be obtained through the diet. This means the term “vitamin” depends on the circumstances and the particular organism, in this case, your individual dog. (

Human vitamins and supplements for dogs are essential for specific health issues. But if your dog is healthy, no nutritional benefit will show up in studies or as evidence. In other words, he does not need them.

If you give your dog too many vitamins or supplements beyond what they need, whether it is human or dog vitamins or supplements, toxicity develops in the dog. To put it quite plainly, by not researching vitamins and supplements for canine use, you will be slowly poisoning your dog to death.

The dogs are then susceptible to the toxins that these vitamins deliver. Additionally, new research shows us that Vitamins A and D are largely the ones that release potential poisons to the dogs’ system. Excessive doses of Vitamin D dietary supplements will cause your dog to become very ill.

Omega 3 Fatty Acids from fish oil sources are helpful to our dogs

Dietary fat for energy is important for humans, dogs, cats and horses; but domestic pets get what they need in their diet. The big question is, “What fats are good for humans, dogs, cats and horses? Is there one type of fat that is good for all four?”

Because of this, fatty acids like salmon oil are given to the dog directly; salmon oil contains EPA and DHA. According to PetMD, Omega 3 Fatty Acids are extremely popular as nutritional supplements for dogs (and humans) for many reasons.

  • Allergies
  • Arthritis
  • Cognitive functions
  • Heart disease
  • Kidney functions
  • Loss of zest and vigor
  • Lymphoma
  • Maintaining a balanced metabolism
  • Maintaining the immune system
  • Skin conditions
  • Stiffening joints
  • Used as a daily supplement rich in EPA and DHA

NOTE: The gels’ properties could just be too big for toy dogs to handle. Piercing the gel and squeezing out the fish oil contents and mixing it with their food can help them consume the supplement.

Human vitamins and supplements for dogs are proven to be toxic 

If you think your dog is toxic due to vitamins and supplements, take them to a vet immediately. Delaying the action can further damage the dog’s system. “Vitamin toxicity occurs when the intake of a dietary vitamin exceeds the normal requirement, causing adverse clinical signs or disease.” (PetPlace)

In many cases, the quality of the dog’s diet is more important than the supplement it takes. The high quality of dog food is ample for the dog’s health and wellbeing. Having an excellent diet of superb quality dog food combined with a vitamin supplement could place the dog at risk ot toxicity due to over dosages.

Over dosage can be fatal to our beloved pets. Just in case any circumstance beyond our control does happen, a pet safety kit is necessary for an emergency.

Having a pet safety kit will have the following contents in it:

  • A turkey baster
  • A can of pet food ( preferably soft )
  • A saline eye flushing formula to wash foreign objects in the eye
  • An Artificial tear gel to lubricate eyes
  • Mild grease-cutting liquid for dishwashing and gloves for bathing the pooch
  • A muzzle to protect yourself from being bitten if the dog is in pain or excited
  • Forceps for stinger tweezing and removal
  • A pet carrier in case you have to take your pooch to a vet.

When a pet is in trouble due to toxicity or poisoning, it is always better not to panic. Most owners do get in a panic mode when poisoning occurs. Panicking does not help. It is important to focus on the problem at hand.  Quick action and a present frame of mind are helpful to save the life of your dog.

Proper cooperation with your vet is the key to maintaining a good balance of vitamins, supplements, and quality dog food for your dog’s health.
