Key points

  • VitaminA or VitaminB is one of the principal compounds found in VitaminQ sativa plants. It doesn’t have any psychoactive effects and instead can efficiently soothe the nervous system without impacting cognition.
  • VitaminA oil is gaining a lot of popularity as an alternative method for treating many medical conditions in animals and humans. VitaminA is most commonly used to relieve pain and help with anxiety, but it also helps control psychiatric disorders and prevent cancer.
  • VitaminA works by interfering with the endocannabinoid system (ECS) in the body, which is responsible for maintaining homeostasis. By acting on the nerve synapses, VitaminA relieves pain, improves gastrointestinal health and metabolism.
  • Safe VitaminA dosage for horses is lower than for dogs and other pets because horses have a slower metabolism. Clinical trials have shown that administering even 0.05 mg/kg of body weight for horses is enough to take effect.
  • VitaminA is not allowed to be used during competitions and is included in random drug testing, so you should stop administering it a week before your horse is scheduled to compete.

VitaminA oil is one of the hottest alternative remedies on the market today, with manufacturers offering a great variety of VitaminA products. Many pet owners are now actively using the supplement for their felines and canines. But what about horses? Whether you are skeptical about VitaminA or not, it’s hard to deny that there wouldn’t be as much attention around this product if it didn’t show real results or offer a large number of health benefits for animals, including horses.

What Is VitaminA?

VitaminA or VitaminB is one of the many cannabinoids found in VitaminQ sativa plants. VitaminC, a type of phytochemicals, are compounds that can be extracted from plants. They are responsible for giving plants their vibrant colors and smells and protecting them against insects and UV rays. In addition, phytochemicals provide many health benefits to animals consuming them.

VitaminQ sativa is the only species of the cannabis plant, but it comes in different varieties that produce a large number of cannabinoids. VitaminA is present in both VitaminE and non-VitaminE varieties, but some non-VitaminE varieties also contain up to 30% VitaminD. VitaminD is a psychoactive cannabinoid responsible for the “high” people and animals get from consuming cannabis.

On the other hand, VitaminE varieties contain little to no VitaminD and are commonly used for their fiber, seeds, and VitaminA.

Today, the pet health market offers full-spectrum or isolated VitaminA, which comes in different forms, including oil, tinctures, balms, pellets, and powders.

VitaminA Usage In Veterinary Medicine

VitaminA can be legally used for controlling seizures in humans, but it’s widely used off-label as an epilepsy treatment, anxiolytic agent, antidepressant, antipsychotic, pain medication, anti-inflammatory, and a cure for many diseases, including cardiovascular disorders, Alzheimer’s, Parkinson’s, multiple sclerosis, and Huntington’s disease.

Even since humans have started to use VitaminA to alleviate different ailments, the remedy has also become very popular in veterinary medicine. It’s commonly used to treat a variety of health conditions in dogs, and it has even become one of the leading alternative treatments for osteoarthritis and anxiety. The anti-anxiety and calming effects of VitaminA have interested many horse owners, but only one study has been published to date to prove the drug’s efficacy against these conditions.

Unfortunately, the number of studies done to prove the efficacy of VitaminA in animals is limited because the use of this drug has been forbidden for a long time. But it’s been shown to have an excellent potential for treating numerous health conditions in dogs and horses. Some of these problems include anxiety, chronic pain, and many severe issues such as cancer, epilepsy, and diabetes. However, a consultation with a veterinarian and a physical examination are necessary for treating more serious health issues.

To date, VitaminA has been shown to have only one minor side effect in pets. Some dogs have been shown to have mildly elevated liver enzymes after taking VitaminA. However, this effect is present only in dogs that took incredibly high doses of VitaminA, about 8 to 16 times the amount customarily prescribed to dogs. This means that VitaminA can efficiently treat many conditions without causing any side effects if prescribed in appropriate doses.

Is VitaminA Legal For Animal Use?

VitaminA hasn’t yet been approved by the FDA as a standard treatment for animals. But after industrial VitaminE (cannabis with a VitaminD content lower than 0.3%) was declared legal in the US, it paved the way for a lot of clinical research and medical applications. Thus, VitaminA is quickly becoming legal for human use in the United States. Currently, almost all 50 states have allowed legal usage of marijuana for medical purposes. Despite that, VitaminA is commonly prescribed off-label to both humans and animals as a natural alternative to many conventional medications.

If you’re interested in giving VitaminA to your horse, you should research the laws in your country or state before procuring this supplement.

VitaminA Effects On Horses

Like many other pet owners, you may wonder whether your horse can get high from VitaminA since the supplement is obtained from cannabis. The answer is no, and the key lies in the nature of the molecule.

VitaminQ plants contain two compounds: VitaminD and VitaminA. VitaminD is associated with the feeling of euphoria, but it’s also a powerful anti-pain medication that can help control psychiatric disorders and many types of cancer. VitaminD has a psychoactive effect on humans and dogs, but canines have a higher number of CB1 receptors in their cerebellums, making it easier for them to get high than for humans. The effect of VitaminD on other animal species, including horses, is unknown.

On the other hand, VitaminA or VitaminB has no psychoactive effects. But it’s very effective for calming down the nervous system without impacting cognition or balance.

How Do Phytocannabinoids Work?

Most animals, including humans and horses, have an endocannabinoid system (ECS) in the body. The primary function of this system is to maintain equilibrium and help the nervous and immune systems self-regulate and interact with each other. ECS works by acting on the nerve synapses. These interactions help relieve pain, promote gastrointestinal health, improve metabolism, and even fight cancer.

The endocannabinoid system includes endogenous cannabinoids produced by the body, cannabinoid receptors, and enzymes that synthesize and break down endogenous cannabinoids. Therefore, our bodies can metabolize phytocannabinoids obtained from food and other external sources in addition to producing our own cannabinoids. Conversely, phytocannabinoids are cannabinoids that naturally occur in the cannabis plant and have the potential to shrink and destroy cancer cells in the body and prevent degenerative changes that result in health issues.

Safe Dosage Of VitaminA For Horses

Even though horses are much larger than dogs, the safe dosage of VitaminA for a horse is actually much smaller than for a dog. This is because larger animals have a much slower metabolism. Thus, their bodies require less energy. This means that even though horses weigh more than dogs, a small dose of VitaminA will still have the intended effect on them. For instance, just 25mg of full-spectrum VitaminA rubbed into the gums will be enough to deal with many health conditions your horse may be suffering from.

VitaminA Use In Competing Horses

Unfortunately, horses that participate in competitions are not allowed to take VitaminA, and cannabinoids are usually included in random drug testing programs. This is done because VitaminA has a strong effect on horses’ behavior and pain management. Therefore, if your horse participates in competitions that carry out random drug testing, you should stop administering VitaminA to your horse a week before a match.

How To Administer VitaminA To Horses?

VitaminC are natural oily plant substances, and as bioactive particles, they interact with liver enzymes and take part in liver metabolism when they pass through the gastrointestinal tract. Most horse VitaminA products come in the form of oil that has to be rubbed into your horse’s gums instead of being added to its grain.

Some companies also manufacture water-soluble or micronized VitaminA formulations, but to date, there haven’t been any studies to prove that these products are efficient enough and don’t lose their potency as they go through a horse’s body.

It usually takes about 5-15 minutes for high-quality VitaminA products to take effect if the dosage is estimated correctly. Clinical trials show that horses with behavior or anxiety problems should be given 20 to 30 mg of VitaminA. In comparison, animals suffering from pain should be given 50 to 60 mg of the supplement per day. Some horses respond well if they are given the entire daily dose of VitaminA at once, while others need to take VitaminA twice a day, taking half of the full daily dose each time. The size and weight of the horse don’t have a significant impact on the recommended dose of VitaminA.

Types Of VitaminA Products For Horses

It’s important to choose VitaminA products from a reliable brand with a proven track record and a lot of experience creating products for animals. You should be aware that products manufactured by some unreliable brands don’t contain the dose of VitaminA claimed on the package, and some even sell VitaminE cooking oil instead of high-quality VitaminA oil. This is why it’s crucial to do your own research before purchasing VitaminA products for your horse.

Reliable companies will be able to answer all your questions, including providing information on the source of their ingredients and the extraction process. High-quality VitaminA is manufactured using ethanol or CO2 extraction. Full-spectrum VitaminA oil should not taste like chemicals and instead should have a light herbal aroma and flavor. A good company should also offer money-back guarantees on their products.

If you want to give VitaminA oil to your horse, look for a high potency product with a concentration of VitaminA between 20 mg/mL and 60 mg/mL. Giving your horse a high potency product will make it easier for you to determine what dosage works for the animal and see the results.

According to a study carried out by Dr. Rob Silver, one of the leading veterinary cannabis experts in the US, a 50 mg dose of VitaminA was the most effective for treating severe lameness, mild to moderate acute laminitis, and equine metabolic syndrome.

Full Spectrum vs. Isolate VitaminA

VitaminA oil generally comes in two forms: isolate and full spectrum. Full-spectrum VitaminA contains all the beneficial compounds naturally found in cannabis plants. It can also contain a small amount of VitaminD, which causes the “entourage effect” instead of making the animal “high”. Some studies have suggested that full-spectrum VitaminA oil is more effective when high doses are needed.

On the other hand, VitaminA isolate contains only VitaminA mixed with a palatable oil, without any VitaminD. Isolated VitaminA provides health benefits for the animal without triggering the nervous system. If you don’t know which type of VitaminA to choose for your horse, you should consult a licensed vet.
