Questions for Dr. Shawn - Supplements, Holistic

Back to Ask Dr Shawn page...

 

"Dear Readers:
”Everyday I have the privilege of helping pet owners try to say “NO” to drugs for their sick pets. I teach them to incorporate many therapies, such as homeopathy, diet, and herbal remedies, into the treatment prescribed for their pets’ ailments. One of the main reasons we work to incorporate supplements rather than conventional medications as part of the therapy is that in general, conventional medications have more side effects than natural therapies. Of course, it is the very rare therapy that can be considered totally safe.

While many think that "natural" equals "safe," this is certainly not true all of the time. Any therapy, be it a conventional drug or herb or nutrient, can have side effects. This is why I discourage owners from purchasing supplements for their use or their pets’ use without medical supervision. Sometimes the use of an herb or supplement can have a side effect by itself, whereas other times the herb or supplement might interfere with the actions of a conventional medication or increase the chance of side effects when used with a certain medication. Side effects can be directly related to the supplement or due to contamination of the supplement during processing (this is especially true with herbal remedies.)

To decrease the chance of side effects from contamination, it is important to only use products from reputable manufacturers. However, in most cases, when used correctly, natural therapies are less likely to have the side effects often encountered when conventional medications are used. For example, even short term use of NSAIDS can result in serious side effects, whereas natural joint supplements like glucosamine are generally used without harm to the patient.

Over the next few weeks I’ll share with you some of the most commonly prescribed supplements and their side effects:

Black Walnut
Black walnut is often used by pet owners as a natural deworming agent, especially to treat heartworm disease. While the history of the herb supports its use to treat parasites, there is no consistent proof of its use as a single agent to treat heartworm infection. This herb is usually considered too toxic to use without veterinary supervision. The tannins and alkaloids may lead to vomiting and diarrhea. Most conventional dewormers (and other herbal deworming preparations) are much safer.

German Chamomile
Chamomile is well known for its sedative effects. Avoid in pregnant animals as it may cause abortion. Usually considered a safe herb, the rare pet may be allergic to chamomile.

Chaparral
Chaparral is reported to be an effective antimicrobial herb. However, ingestion of large amounts can lead to liver damage; avoid in pets with liver disease; potentially a very toxic herb and not usually recommended.

Red Clover
Red clover is used in many herbal cancer formulas due to its diuretic, blood cleansing, and anti-neoplastic effects. Red clover contains coumadin and should not be used in pets with blood clotting disorders. If fed in large amounts, the estrogenic components can be toxic. Do not use in pregnant animals. Red clover contains very small amounts of salicylic acid (aspirin,) and care should be used in pets taking corticosteroids or non-steroidal medications and in cats which are sensitive to salicylic acid.

Comfrey
Comfrey has been used for its anti-inflammatory and lubricating properties. Comfrey contains alkaloids that can cause liver damage or cance. While the leaves (the most commonly used part of the herb) contain almost negligible amounts of alkaloids (the roots contain the most and should never be used,) many doctors consider it too toxic to use for any reason.

Echinacea
Echinacea is a well-known immune modulating supplement. For immune system disorders (autoimmune diseases, diabetes) and disorders with diminished immune systems with low white blood cell counts (feline leukemia and immunodeficiency diseases,) it was recommended in the older literature to avoid this herb as echinacea is used for immune stimulation. However, there have been no clinical studies supporting this recommendation, and echincacea has been safely used in people with these disorders. The older literature also recommended not using the herb for longer than 4-8 weeks without giving the body a "break," but again this has not been substantiated clinically and it has in fact been used for longer periods of time without harm. Most veterinarians prefer to use echinacea early in the course of the disease at the first signs of infection to properly and fully modulate the immune system. Caution is warranted in diabetics as the condition may become unstable.

Ephedra
Ephedra has a long history of use in Traditional Chinese Medicine as an effective therapy for respiratory (especially asthmatic) disorders. While it has been reported that cats may exhibit idiosyncratic reactions, I have not had any side effects in cats treated with ephedra for upper respiratory disease. Ephedra, most commonly prescribed for pets with asthma or respiratory problems, can cause heart arrhythmias and high blood pressure. Use with great caution in all pets. It should not be used when medications which have similar actions are used (MAO inhibitors, sympathomimetics) or in pets with hypertension, cardiac arrhythmias, anxiety, restlessness, glaucoma, cardiovascular disease, impaired cerebral circulation, prostatic adenoma, pheochromocytoma, or hyperthyroidism.

Garlic
Garlic has been historically recommended for many uses, including the treatment of parasites, microbial infections, and in the treatment of cancer. Garlic in large amounts can cause Heinz body anemia in dogs and cats due to the presence of S-methyl cysteine sulfoxide and N-propyldisulfhide. Do not use in pets with anemia. Garlic in high doses can prolong bleeding times. As a general guideline, 1 clove of garlic per 10 pounds of body weight for dogs (and 1/2 clove per cat) can usually be fed safely each day if the pet is not anemic.

Ginkgo Biloba
Ginkgo is well known for its use in treating mild forms of cognitive disorder and intermittent claudication in people. Ginkgo has antithrombotic activity via its PAF inhibition. Caution should be used if ginkgo is given to patients taking anticoagulant or antithrombotic medications (aspirin, NSAIDS.) It has been suggested that antiplatelet medications and herbs be stopped about 1 week prior to surgery. Rare reports of spontaneous bleeding (subdural hematomas, hyphema, subarachnoid hemorrhage) are reported in the human literature, especially when combined with high doses of fish oil or other anti-clotting medications.. No reports are noted in pets. Do not use in animals with blood clotting disorders. Do not use in pregnant animals.

Kava kava
Kava has a long traditional history of being a good calming, sedative herb. Can be toxic to the liver in excess amounts and it should not be used in pets with liver disease. There have been recent reports of liver toxicity and death in depressed people treated with this herb. However, careful analysis of these reports revealed that these patients had preexisting liver disease, were taking drugs with potential hepatotoxicity, or where suffereing from chronic alcoholism. The herb has a long history of safety but it is recommended to screen for liver disease before using the herb and to periodically monitor liver enzymes if the herb needs to be given for long-term use. Do not use in pregnant animals. May interact with anxiolytic medications (Valium, etc.)

Milk Thistle
Milk thistle is well-known for its treatment of liver disease. Do not use in pregnant animals. Long term use in normal animals may result in depressed liver function unless chronic liver disease is present. It is not recommended to use milk thistle to prevent liver disease.

Passionflower
This herb is used for its sedative effects. Do not use in pregnant animals. Excessive doses may cause sedation and potentiate the effects of drugs that are monoamine oxidase (MAO) medications.

Pennyroyal
While pennyroyal oil is an effective insecticide, due to potential severe toxicity and death pennyroyal oil is not recommended for use in pets.

Tea Tree
Tea tree oil is used topically for its antimicrobial effects. It can also help itching and control external parasites like fleas. It is generally recommended not to use most volatile oils in cats, or only do so with proper dilution and supervision. Small-breed dogs may also be sensitive to undiluted oil. The safest way to use this product is to only purchase properly prepared and already diluted products.

Valerian
This herb is used for its sedative effects. Do not use it in pregnant animals. It can cause gastrointestinal upset in large doses. Do not use with similar medications (barbiturates or benzodiazepenes like Valium) without medical supervision as increased sedation may occur.

Wormwood
Like black walnut, this is another traditional deworming herb. It is considered unsafe for internal use in people without careful supervision. Do not use in pets with seizures, kidney disease, liver disease, or in pregnant animals. Safer herbs for deworming exist and wormwood should only be used with extreme caution.

St. John's Wort
This is used as a natural sedative. Some pets may develop sensitivity to sun exposure, although this is unlikely in dogs and cats when used at recommended dosages. It may interact with other similar medications. Serotonin syndrome may occur if combined with SSRI medications. St. John's Wort may interfere with the metabolism of medications administered with St. John’s Wort."

"Dear Dr. Shawn:
"After reading The Natural Health Bible for Dogs & Cats, I know that you’re a big believer in using supplements in pets. However, since I feed my dog what I think is a really good natural diet, is supplementation still important? Is there anything in particular you would recommend?"

Answer:
"Like you, I’m a big believer in feeding the proper diet AND combining the best diet with whatever supplements your pet requires. I’m assuming for this discussion that your pet is healthy and does not have any specific needs that I should address. The foundation of any holistic health program starts with a good, natural diet, preferably one free from byproducts and chemicals. However, even the best diets may not provide everything your pet needs to maintain health. This is because diets are formulated for the “average” pet, and I’ve yet to see any "average" pet.

There is a lot of evidence that support the benefits of vitamin and mineral supplementation for all diets. This is especially true for pet foods that are not natural and holistic such as the one you’ve chosen to feed; many foods are lacking nutritional enhancement and the ingredients used are byproducts from human grade materials that are not fit for human consumption and are deficient in many important nutrients. The diet is a starting place, and supplements are used depending upon each pet’s specific needs. Having said this, I think I can make some general recommendations regarding supplements that will be true for all pets."

"Dear Dr. Shawn:
"I was wondering how you decide which supplements you use in your practice and recommend on your radio show? I want to give my pets the best and I need your help in making suggestions. My cat is 9 years old and my dog is 4 years old, and both are healthy at this time. Thanks for your help!"

Answer:
There are 3 things I look at when deciding which supplements to sell or recommend.

1. The product itself

The supplement must be of the highest quality, and ideally possess healing properties or ingredients not found in other products. I prefer supplements manufactured using GMP (good manufacturing practices) and bearing the NASC (National Animal Supplement Council) seal of approval, which guarantees products of the highest quality. I prefer pet supplements for pets as these are made to be tasty (and therefore easy to administer) for pets and are formulated in the correct dosage for pets.

2. The manufacturer

The integrity of the manufacturer is very important in my consideration of supplements. Fortunately, I personally know most of the representatives (and often the CEO’s) of the companies with which I do business. In a number of cases, I have been so impressed with the company that I have consulted with them, served as a spokesman for them, and/or done research on the supplements which the company sells. I only work with those companies which are committed to advancing animal health by making and selling quality supplements. I especially like it if the company also supports the veterinary profession and returns some of its profits to pet charities.

3. The cost

The cost of a supplement, while important, is the least important factor in my decision to prescribe or recommend a supplement. All things being equal, I will of course choose the most cost effective product.

Keep in mind that I can prescribe and sell CHEAP supplements, or I can prescribe and sell GOOD supplements. I prefer to explain price once rather than apologize forever for a poorly made supplement that doesn’t’ help the pet. It’s also important to compare supplements by the cost of a DOSE rather than the cost of a BOTTLE of the supplement. If Supplement A costs $20 for a bottle of 90 pills but only lasts 9 days, and Supplement B costs $50 for a bottle of 90 pills but lasts 3 months, Supplement B is the less expensive and better value. You MUST figure out the per dose price in order to compare the cost of supplements!

Here are 2 supplements I recommend for all of my patients (I consult with the manufacturers of these products.) These would work well for your dog and cat.

Vim & Vigor is my favorite, basic supplement for all pets. It supports a healthy immune system, bowels, bladder, joints, connective tissue, heart, and gums. It has improved the health of many of my patients. I also find it particularly useful for cats with hairballs and litterbox odor, pets that have restless sleep (especially older dogs and cats and puppies and kittens,) and itchy dogs and cats.

Cholodin (www.mvplabs.com/dietary.products.htm) is prescribed for pets 5 years of age and older. It is a great “senior citizen” supplement that delays the onset of cognitive disorder (doggie and kittie Alzheimer’s.) Pets with arthritis can use Cholodin-Flex to support aging joints.

For dental health issues, I recommend the easy-to-use oral health products from Oxyfresh. See my oral health page for more information.

Check with your veterinarian to see which additional supplements can be added as health concerns arise.

"Dear Dr. Shawn:
"I think I remember you writing a column last year about supplements and side effects. Can you tell me which supplements are safe to give and don’t have any side effects?"

Answer:
"This is a good question. While many people think that “natural” means “safe,” this is not true. Many supplements, especially herbs, can be very potent and even deadly if not used correctly or if combined with other supplements or medications. Here are some common supplements that are generally considered safe. Keep in mind that I still recommend you use them under veterinary supervision to make sure the proper diagnosis is made and the correct dosage of the supplement is prescribed.

Fatty Acids
Both flax seed and fish oil are considered very safe when used at commonly recommended doses. High doses of fish oil have caused brain hemorrhages in some people when combined with other supplements or medications that interfere with blood clotting.

Joint Supplements
Hyaluronic acid, glucosamine, and chondroitin are safe when used at recommended doses. They are very effective in controlling joint pain and are much safer than commonly prescribed NSAID medications

Vitamins and Minerals
When given as combination animal (not people) products, most of these supplements should be safe. Individual vitamins, especially when used in high doses, act like drugs and can be dangerous and should only be used under veterinary supervision.

Probiotics
Probiotics are used to help pets with gastrointestinal problems and are safe when used as directed.

Enzymes
Enzymes are among the safest supplements, although one of my own patients has experienced seizures as an idiosyncratic reaction to one particular product.

Green Foods
These supplements, typical grasses like barley grass, wheat grass, algae, or spirulina are usually safe when used as directed.”
