Are PureForm supplements "natural"?

A controversy has been raging for years about the relative virtues of synthetic vs. natural nutrients. 

Fun Fact: All foods, vitamins, and nutrients, and all the other substances of life, are chemicals. If all life is made of chemical molecules, a chemical's structure, not its source, determines its function. 

So, there is no difference between a synthetic molecule of a vitamin or other nutrient and a natural molecule of the same vitamin or nutrient (chemical). One comes from the biological factory and the other from a brick and mortar factory, but the sources of the chemicals’ characteristics come from its structure, not its location.

We use "natural" sources of the ingredients where applicable. There are some ingredients, such as Vitamin E (dl-alpha tocopheryl acetate), which is synthetic but also enhanced by synergistic ingredients in our formulas.  

Why do the supplements state "not for long-term use"?

Health Canada requires us to add this disclaimer. However, it is safe. Feel free to consult your veterinarian or have them contact us if they have questions.

What's the best way to mix supplements with the food?

Many horses and pets love it sprinkled right on top of the food. If you want to give it a stir, or add a bit of liquid, go for it! WHen starting a new supplement, we always suggest to start at a half recommended does or even a pinch to test palatability. Your furry friend will let you know how he likes it. 

Where does your Glucosamine come from?

Plant source. Vegetarian and Vegan Glucosamine Hydrochloride is an alternative form of glucosamine sourced from shellfish/crustations.

Vegan class D-Glucosamine HCl can be manufactured by fermentation to extract chitosan (D-glucosamine, 83.64%)  from Chicory Root or a fungus known as Aspergillus Niger.

Glucosamine is produced naturally in the joints of the body but is rarely found in major food sources.

Can Glucosamine Plus (equine) be used for dogs?

Yes it can. However, the type of vitamin C we use for equine is different from the type we use in our canine formulas. It will differ in absorption and pH. We recommend PureForm Agility for dogs as it also incorporated the marine sourced glucosamine hydrochloride and l-glycine which helps with small animal anxieties. 

Are there other ingredients in your formula not listed on the site?

There are NO inactive ingredients in our formula. Everything you see listed on our website is what you'll receive in your supplement, no more or less! We don't add fillers such as liquid, whey, flax, or flours in our formulas. Nor do we add sugars or preservatives. This is our promise to you. 




The fat-soluble vitamins are stored in your horse’s body and used as needed. Hard-working horses or horses under stress can deplete stores of fat-soluble vitamins leading to deficiencies.

Vitamin A

Vitamin A plays a role in digestion, respiration, reproduction, and vision. In growing horses vitamin A is important to proper bone development. Vitamin A is not found in nature; instead, it is synthesized from carotenes in the small intestine. Green grass is an excellent natural source of beta-carotene, which is metabolized into vitamin A. When green grass is lacking in the diet it is particularly important that vitamin A be supplemented.

Vitamin D

Vitamin D plays a major role in the absorption of calcium in the small intestine. Once absorbed, vitamin D aids in the transportation to and the accumulation of calcium in the bone and other tissues.

Vitamin E

Vitamin E cannot be synthesized by the horse; therefore, it is considered an essential nutrient and a powerful antioxidant that limits the damage caused by oxidative stress and the actions of free radicals. It maintains healthy muscle and nerve function and supports a strong immune system in horses of all ages.

The best source of vitamin E is fresh green grass; however, the potency of vitamin E declines very quickly once forages are harvested and dried. Multiple research studies have shown that vitamin E is often deficient in the diets of horses that do not have access to continual grazing on fresh green grass, or those grazing on winter pasture. Note about synthetic (dl-alpha-tocopherol) and the natural vitamin E (d-alpha-tocopherol), studies do show that natural vitamin E is two to three times more potent than synthetic. This formula allows for that ratio to be an effective antioxidant.


Water-soluble vitamins are not stored in your horse’s body, so they need to be provided in the proper amounts in the diet. Horses that are working hard or are stressed may need additional supplementation.

Thiamine, Niacin, Pantothenic Acid

These vitamins play a role in the metabolism of proteins, fats, and carbohydrates.


Also known as B2, riboflavin influences energy production and growth.

Folic Acid

Folic acid, or B9, is important for red blood cell development.

Vitamin B12

Cobalamin, B12, plays a role in energy metabolism and maintaining the manufacturing of red blood cells.


Choline supports cellular functions in multiple ways. It is a component of lipids and plays an important role in normal cell structure and activity. It contributes to normal fat metabolism in the liver, increasing fatty acid utilization. As a precursor of acetylcholine, it supports the transmission of nerve impulses. Choline is thought to have an impact on concentration, memory and muscle performance, and prevents fat buildup in the liver.


Minerals are inorganic compounds that serve both as components in body tissue and as catalysts for various body processes. The trace minerals in MetaBoost are chelated, which increases digestibility and absorption.


A main building block of your horse’s skeleton, calcium also supports proper muscle contractions and plays a role in blood clotting.


Essential to healthy bones and energy transfer reactions, phosphorus also plays a role in the synthesis of certain proteins. Calcium and phosphorus must be provided in the appropriate ratio range of 2:1 to 1:1.


Copper is necessary for healthy connective tissue, cartilage, and bone. Other important functions of copper include red blood cell formation, hoof wall formation, and hair pigmentation.


Selenium works in concert with vitamin E to defend the body’s cells from damaging oxidative by-products known as free radicals. Selenium is a component of a beneficial enzyme that prevents free radicals from forming. Free radicals are released during normal energy production. Horses use energy to fuel bodily functions and movement.


Zinc plays a role in healthy hooves and coat, bone development, and reproduction. It is also critical to proper immune function. Zinc is a trace mineral vital to proper enzyme function in protein metabolism. MetaBOOST contains zinc proteinate, the form of zinc most easily digested by horses.


Research has shown that high-quality yeast cultures help horses maintain a healthy digestive tract and increase the digestibility of nutrients by stimulating the activity of the good microorganisms in the hindgut. A healthy microbial population will also reduce the incidence of digestive upset and contribute to a healthy immune system.
