Alfalfa is a calcium-rich, protein-dense forage often used to support gastric comfort in horses, especially when stomach acid may irritate the upper (squamous) stomach. In research, horses fed alfalfa had higher gastric pH and fewer, less severe squamous lesions compared with some grass-hay diets, suggesting a buffering effect when used appropriately in the ration. It also supplies highly usable protein and key minerals that can helpmaintaintopline and overall condition in growing horses, broodmares, and hard keepers. (Nadeau et al., 2000; Verhelst, 2025)

Algal oil is a sustainable, traceable source of omega-3s, naturally rich in DHA and often EPA, and it supports the body’s healthy inflammatory balance. 

• Joint health: Omega-3s help keep the normal inflammatory response in check, which can support more comfortable movement and recovery after exercise. 
• Skin and coat: DHA and EPA support the skin barrier, helping reduce dryness and supporting a softer, shinier coat, especially in animals prone to flaky skin or seasonal itchiness. 
• Lung health: Omega-3s can support respiratory comfort by helping maintain a balanced inflammatory response in the airways, which is relevant for pets that react to dust, pollen, or environmental triggers. 

Because algal oil delivers omega-3s in a consistent way, it is a practical alternative to fish oil for long-term daily support of joints, skin, and respiratory resilience (ScienceDirect). 

Alpha-amylase is a digestive enzyme responsible for breaking down complex starch molecules into smaller sugars that can be absorbed in the digestive tract. Efficient starch digestion supports balanced nutrient absorption and digestive efficiency. Richards et. al., 2003

In animals consuming carbohydrate-containing diets, enzymatic activity helps facilitate the breakdown of starch before it reaches the hindgut, where excessive fermentation can sometimes contribute to digestive disturbances.

For this reason, supplemental enzymes such as alpha-amylase are sometimes included in digestive formulations to support nutrient digestion and maintain gastrointestinal stability.

Apple (Malus domestica) is a natural source of pectin, a soluble fiber known for its role in supporting digestive health. Pectin forms a gel-like structure in the gut, which helps regulate intestinal transit and contributes to normal stool consistency.

As a fermentable fiber, pectin serves as a substrate for beneficial gut bacteria. This supports a balanced microbiome, which plays an important role in digestion, nutrient absorption, and overall gut health.

The gut and nervous system are closely connected through the gut–brain axis. Supporting a stable gut environment can therefore contribute to overall wellbeing and a more balanced response to everyday stressors. This makes pectin relevant not only for digestive support but also as part of a broader approach to maintaining calm and comfort in sensitive animals (Wikiera, 2014; Zaitseva, 2020).

Apple pulp is a fiber-rich ingredient derived from apples (Malus domestica) after juice extraction. It contains soluble and insoluble fibers, including pectin, which contribute to maintaining normal digestive function and supporting a balanced intestinal environment.

Dietary fibers such as pectin can help support beneficial microbial activity in the hindgut, which plays an important role in equine digestion. A balanced hindgut microbiome supports nutrient absorption and overall digestive stability.

Because of its natural fiber content and palatability, apple pulp is often included in equine nutrition to complement forage-based diets and support digestive wellbeing while contributing to overall nutritional balance.

L-arginine is a functional amino acid involved in several important metabolic pathways. One of its key roles is serving as a precursor for nitric oxide, a signaling molecule that helps regulate blood flow and vascular function.

Healthy circulation supports the delivery of oxygen and nutrients to tissues with high renewal needs, such as the skin and hoof. This makes arginine relevant for dogs in formulas aimed at maintaining healthy skin, and for horses where hoof quality and metabolic balance are important.

Nitric oxide is also involved in normal skin physiology, including barrier function, immune signaling, and tissue renewal. Through its role in nitric oxide production, arginine contributes to overall tissue resilience and physiological balance (E Seifter, 1978; Siani, 2013).

Spirulina (Arthrospira platensis) is a nutrient-rich microalgae known for its high protein content and abundance of vitamins, minerals, and antioxidant pigments. It contains essential amino acids as well as bioactive compounds such as phycocyanin and beta-carotene. 

These pigments have been widely studied for their antioxidant properties and their role in supporting healthy tissues and cellular protection. Antioxidants help maintain normal skin integrity and support hair follicle health, both important factors for a healthy coat (Aksoy, 2024). 

Because skin and coat condition often reflect overall nutritional balance, spirulina is sometimes included in pet nutrition as a natural source of protein, micronutrients, and antioxidant compounds that contribute to overall vitality (Cabrita, 2025).

Ashwagandha is an adaptogenic root traditionally used to support resilience during stress.

Astaxanthin is a naturally occurring carotenoid, usually sourced from microalgae, and is used in horses to support antioxidant protection and recovery, especially around training and competition. It helps protect cells from oxidative stress generated during exercise and can support healthy muscle recovery and overall resilience. 

What makes astaxanthin stand out is its very strong antioxidant activity. In the scientific literature, astaxanthin has been reported to be more than 100 times stronger than vitamin E at protecting fats from oxidation (lipid peroxidation) in laboratory comparisons, and even higher for certain oxidative reactions, depending on the test method. (ScienceDirect) 

In horses, recent peer-reviewed studies in racing horses found that astaxanthin supplementation was associated with reduced markers of oxidative stress and inflammation and improved antioxidant status, supporting its use as part of a performance and recovery plan. (nature.com) 

Oatmeal derived from oats (Avena sativa) provides a dense source of essential nutrients including zinc, iron, and B vitamins (European Journal of Nutrition). These micronutrients play important roles in metabolic pathways involved in normal hormone production and reproductive physiology.

Zinc and iron contribute to enzymatic processes that are important for cellular metabolism and tissue development, while B vitamins support energy metabolism and the synthesis of hormones and signaling molecules. Maintaining adequate levels of these nutrients is particularly important for broodmares before breeding and during pregnancy, when nutrient demands increase to support both the mare and the developing foal. (Kelleher, S.L., 2009)

Because of its balanced nutritional profile and high digestibility, oatmeal is often included in equine breeding rations to help maintain metabolic balance and support overall reproductive nutrition.

Bacillus subtilis is a spore-forming probiotic bacterium that is valued for its stability and ability to survive harsh conditions such as stomach acid. Once in the digestive tract, it can contribute to maintaining a balanced gut microbiome.

Because of its resilience and activity in the gut, Bacillus subtilis is often used to support digestive stability and maintain normal stool quality in dogs with sensitive digestion (ScienceDirect, 2020; Portella Félix; 2010).

Sugar beet pulp is a highly fermentable fiber often used in horse diets to support healthy hindgut fermentation and provide steady energy without the starch load of many grains. Research in horses has evaluated beet pulp inclusion for digestibility and metabolic responses, supporting its reputation as a useful “super fiber” for condition, older horses, and horses needing more calories from fiber. It must be introduced gradually and balanced within the full ration. ScienceDirect

Barberry (Berberis vulgaris) is valued for berberine, a plant alkaloid widely studied for its effects on metabolic pathways involved in glucose and lipid regulation. In experimental and clinical research, berberine has been shown to influence cellular energy metabolism, including activation of AMP-activated protein kinase (AMPK), a key regulator of glucose and fat metabolism.

Because metabolic balance plays an important role in weight regulation and dietary responses, ingredients containing berberine are often included in nutritional strategies aimed at supporting metabolic resilience. Research has shown that berberine can influence glucose handling and insulin signaling, mechanisms that are relevant in animals prone to metabolic imbalance.

By supporting metabolic pathways linked to energy use and glucose regulation, barberry-derived compounds are increasingly explored as supportive nutritional ingredients in metabolic health programs (Kong et al., 2004; Pirillo & Catapano, 2015; Imenshahidi & Hosseinzadeh, 2016).

Bisabolol is a naturally occurring compound commonly derived from chamomile. It is widely used in skincare formulations for its soothing properties and its ability to support sensitive or irritated skin.

Choline is an essential nutrient involved in several important physiological processes in animals. One of its key roles is serving as a precursor for phosphatidylcholine, a major phospholipid that forms part of cell membranes and contributes to maintaining normal cellular structure and function.

Choline is also involved in lipid metabolism. It helps transport fats within the body by supporting the formation of lipoproteins, which are responsible for moving lipids through the bloodstream. Proper lipid metabolism is important for maintaining normal metabolic balance and supporting the function of organs involved in nutrient processing. Kenny et. al., 2025

In addition, choline contributes to the synthesis of acetylcholine, an important neurotransmitter involved in nerve signaling. Through these roles in cell membrane structure, metabolism, and nervous system function, choline supports normal physiological processes in growing animals as well as in animals with higher nutritional demands. Nutrients, 2020

Because animals cannot always produce sufficient amounts themselves, choline is commonly included in complete nutritional formulations to support cellular health, metabolic balance, and overall physiological function.

Chrysanthellum is a traditional botanical often linked to liver and circulation support, largely because it contains polyphenols and other plant compounds studied for antioxidant activity. Langhi et al. 2024

Vitamin B12 (cobalamin) is a water-soluble vitamin that plays an essential role in energy metabolism and cellular function. It participates in enzymatic reactions involved in DNA synthesis and the formation of red blood cells, which are important for oxygen transport and overall vitality.

Vitamin B12 works closely together with folate in one-carbon metabolism, a pathway involved in the synthesis van nucleic acids and other essential biological molecules. These processes support cellular growth, tissue maintenance, and overall metabolic balance.

In addition, vitamin B12 contributes to normal nervous system function and is involved in pathways linked to mood regulation. Research shows that low vitamin B12 levels are associated with changes in mood and increased signs of stress-related conditions such as anxiety and depression. Maintaining adequate levels therefore supports overall mental balance and resilience (Todorov et al., 2017 ; Stover, 2004; Curely, 2025).

Coconut oil is rich in medium-chain triglycerides (MCTs), a type of fat that is absorbed and used for energy more rapidly than many long-chain fats. This makes it a practicaloptionwhen you want an easy-to-use calorie boost for horses without the sugar rush often associated with concentrates. Research suggests that MCT-based diets can shift how the body uses fuel, supporting quick energy availability. Coconut oil may also support skin health. Craig et al., 2003

Collagen is one of the most abundant structural proteins in the body and a key component of connective tissues such as cartilage, tendons, ligaments, and skin. It provides strength, flexibility, and structural support, which are essential for normal movement and tissue integrity.

In joints, collagen is an important part of cartilage, where it contributes to resilience and helps absorb mechanical stress during movement. Supporting collagen availability contributes to maintaining joint structure and mobility.

Collagen is continuously broken down and renewed in the body. Nutritional support can contribute to this natural turnover and to processes involved in tissue repair and extracellular matrix maintenance, which are important for overall musculoskeletal health (Golda et al., 2024; Merkuriusz Lekarski, 2011).

Colostrum contains immunoglobulins and growth factors that can support the gutlining and immune defenses. In dogs, published research has explored its influence on immune function during longer-term feeding, which is why it is often positioned for digestive and immune resilience. It is supportive nutrition, not a substitute for investigating chronic diarrhea, weight loss, or suspected allergies (Satyaraj; 2013; Beynen, 2013; DuBourdieu, 2019).

Cranberry is used to support urinary tract health in dogs and cats because it contains proanthocyanidins (often called PACs) that can make it harder for certain bacteria, especially E. coli, to stick to the bladder wall. When bacteria cannot attach as easily, they are more likely to be flushed out during normal urination. This is why cranberry is mainly positioned for prevention support in pets that are prone to recurring urinary issues, not as a stand-alone solution for an active infection. 

In practice, cranberry works best as part of a broader urinary plan, alongside good hydration and regular toilet breaks for dogs. It should not replace veterinary care if a pet shows signs of a UTI such as frequent urination, straining, accidents, blood in the urine, pain, or lethargy. Cats in particular can have urinary problems that are not bacterial (for example stress-related inflammation), so getting the right diagnosis matters. Chou HI et al., 2016, Olby et al., 2006 

Pumpkin (Cucurbita pepo) is valued in pet nutrition for its naturally high fiber content and balanced nutritional profile. It contains both soluble and insoluble fibers that help support normal digestive processes and contribute to healthy intestinal function.

Ginger is also linked to processes involved in bile production and flow. Bile plays a key role in digestion and contributes to the processing of dietary fats and metabolic by-products. Supporting these natural processes helps maintain normal liver and digestive function (Williams & Lamprecht, 2008; BenthamDirect).

Glucosamine is a naturally occurring amino monosaccharide that serves as a building block for glycosaminoglycans and other structural molecules in the body. Glycosaminoglycans are important components of connective tissues such as cartilage and also contribute to the structure of mucosal surfaces throughout the body.

These molecules help maintain the strength, elasticity, and structural integrity of connective tissues. In biological systems, glucosamine participates in pathways that support the synthesis and maintenance of these structural components, which are essential for maintaining normal tissue function.

Glycosaminoglycans and related molecules also contribute to the protective mucosal layers found in the gastrointestinal tract. These layers help maintain barrier integrity and support the interaction between the intestinal lining and the microbiome, which is important for digestive stability and overall physiological balance.

Because of its role as a structural precursor in connective tissues and mucosal systems, glucosamine is often included in nutritional formulations aimed at supporting tissue maintenance, gastrointestinal integrity, and overall physiological resilience. ScienceDirect

L-glutamine is a conditionally essential amino acid that plays an important role in cellular metabolism and tissue maintenance. It is one of the most abundant amino acids in the body and serves as a key fuel source for rapidly dividing cells, including intestinal epithelial cells and immune cells.

In muscle tissue, glutamine participates in nitrogen transport and amino acid metabolism, processes that are involved in muscle protein turnover and recovery following physical activity. Because of this role in cellular metabolism, glutamine is commonly studied in relation to exercise, recovery, and metabolic support.

Glutamine also contributes to maintaining the integrity of the intestinal barrier, as intestinal cells rely on it as an energy source. For this reason, it is often included in nutritional strategies aimed at supporting both digestive health and overall physiological resilience (M. I. Lindinger, 2020).
