Frequently Asked Questions

What Does Quercetin Do For Dogs?

Quercetin is a bioflavonoid, a type of phytonutrient made by many plants. This particular phytonutrient has anti-inflammatory, antioxidant, and antihistamine properties. By stopping the mast cells from releasing histamine, quercetin can lessen or stop allergic reactions. Free radicals need to be neutralized in order to reduce inflammation in the body and stop allergic reactions, which brings in antioxidants.

They stick to the free radicals and take away their ability to damage the body. Some dogs even find relief from itching when taking this supplement. As allergies can attack the skin, they can cause irritation to your dog’s fur or skin underneath. Quercetin can also be used to help control weight, treat heart conditions, and keep bones healthy. Also, it lowers blood pressure and lessens the effects of bad cholesterol or low-density lipoproteins.

It is important to remember that quercetin is not just a health superstar when it comes to allergies. As an antioxidant, it has many other health benefits as well. Several studies have shown that quercetin can stop cancer cells from growing or get rid of them all together in different organs. Cancer kills millions of dogs every year, so this research on quercetin is not only important but urgent.

Is It Safe To Give Dogs Quercetin?

Quercetin is safe for dogs when given at the right dosage. Some side effects that can happen to people are stomachaches and headaches. If your dog has kidney disease, talk to your vet before giving him quercetin. Further, do not give quercetin to your dog if she might be pregnant or nursing. If your dog has kidney problems, you should also keep him away from quercetin.

It is also not a good idea to add quercetin to your dog’s food if she is already taking medicine without first talking to your vet about any possible side effects. Quercetin can affect the way antibiotics, cyclosporine, diabetes drugs, blood pressure drugs, and drugs that are broken down by the liver work. Because quercetin can change how well these medicines work, it is important to have a professional watch over any changes you make to your dog’s daily diet.

How Long Can Dogs Take Quercetin?

Quercetin often starts working quickly in dogs, which is good as they should not take it for more than twelve weeks at a time. Taking the supplement longer can damage their kidneys or liver. Always talk to a veterinarian when giving your dog this supplement.

Does Quercetin Work For Dog Allergies?

People often call quercetin “nature’s Benadryl” because it helps control the histamine response in the body to allergens and inflammation. Histamines cause a hypersensitivity reaction that causes redness, swelling, itching, and sometimes even pain in both dogs and humans. Quercetin treats those allergies naturally without prescription medication.

Due to constant scratching, biting, and licking to relieve the itching caused by allergies, many other problems can arise in dogs. For example, some dogs will experience dermatitis caused by bacterial and fungal infections, which can be painful. Allergies can hurt a pet’s health and quality of life, and they can be very annoying for their owners.

What Are The Side Effects Of Quercetin In Dogs?

Quercetin does not cause many side effects in dogs, but too much of anything can be bad. If your dog gets too much quercetin, it could get a stomachache, a headache, or loss of appetite. Your dog may become drowsy or have a faster heart rate if they take it long enough to damage their kidneys. Additionally, when given on an empty stomach, quercetin can make some dogs feel sick or make them eat less. If any of these things happen while your pet is taking this supplement, give it to your dog with food.

Does Quercetin Help With Inflammation In Dogs?

Quercetin works to stop inflammation and cut down on how much histamine a dog’s body makes. This means that a dog will feel less itchy if he comes in contact with pollen or another allergen. It’s most often given to pets to help with the itching, swelling, and pain that come from allergies.

Does Quercetin Stop Itching?

Yes, quercetin works to stop inflammation and cut down on how much histamine a dog’s body makes. This means that a dog will feel less itchy if he or she comes in contact with pollen or another allergen. Quercetin can be used instead of common medicines like Benadryl to make your dog feel better, but studies have shown that it works differently for different dogs. This means that quercetin might not work as fast as Benadryl.

Can Quercetin Cause Liver Damage?

Quercetin for short durations is safe for pets but given for too long, it can cause damage to the liver, but only when taken with other medicines that can cause liver damage. Blood pressure and heart medicines like amlodipine, enalapril, diltiazem, and furosemide can cause side effects when taken with quercetin, as can many others, which is why you should talk to your vet before giving this supplement to your furbaby. 

What Is A Holistic Treatment For Allergies In Dogs?

You can also use aloe vera gel, calendula, thyme, chickweed gel, apple cider vinegar, witch hazel, Epsom salts, and slices of cucumber to soothe irritations in dogs. If your pet has a grain allergy, do not give them an oatmeal bath. Additionally, you can give them omega fatty acids to help the immune system and reduce inflammation and itching. Oils from wild salmon, anchovies, and sardines, as well as flaxseed oil, are good sources.

What Are Natural Alternatives To Apoquel?

Apoquel is not a drug that is meant to be used for a short time or to treat dermatitis. It is a drug that vets use when they can not figure out why their patient is itching or when other treatments have not worked. Once a dog starts taking Apoquel, they usually have to keep taking it for the rest of their lives. Instead, yucca and quercetin are great natural alternatives to Apoquel without negative side effects. Yucca has a similar effect to steroid drugs, but it does not have any of the bad side effects.

What Is The Best Natural Antihistamine For Dogs?

Many holistic veterinarians say that quercetin is like Benadryl but made by nature. It is a natural alternative to Apoquel that is safe to use. Quercetin blocks inflammatory enzymes and stops the histamine reaction, which makes swelling and itching go away. During allergy season, quercetin can help your dog feel better, making it the best natural antihistamine. 

What Is The Best Thing To Do For Dogs With Allergies?

If you do not want to give your pet a pill, there are other ways, such as natural remedies, to ease their symptoms. Here are the best options: 

  • Prevent fleas and ticks with treated collars
  • Use topical sprays and creams 
  • Give your dog baths with soothing ingredients 
  • Clean their paws and fur when they come indoors 
  • Supplement their diet with omega fatty acids 
  • Avoid allergens known to cause issues for your dog

Can Quercetin Make Allergies Worse?

No, because they are a part of food that comes from nature. If your dog is not allergic to quercetin, which is very unlikely, it can not make allergies worse, especially when given in the right amounts. However, remember that quercetin can react to certain medications and can affect the kidney or liver if taken long-term.
