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.

Vitamin E (D-alpha-tocopherol) is an essential fat-soluble antioxidant that helps protect cell membranes from oxidative stress. Because these membranes are rich in fatty acids, they are particularly sensitive to oxidative damage, making antioxidant protection important for normal cellular function (ScienceDirect, 2014).

Vitamin E plays an important role in maintaining muscle cell integrity and supports normal nerve function. It also contributes to immune function and helps maintain healthy tissues such as skin and coat (Fagan, 2018).

Horses naturally obtain vitamin E from fresh grass, but intake can be limited when pasture access is restricted, making additional supply relevant (University of California, 2019).

Vitamin E can occur in different forms (tocopherols), each with specific antioxidant properties. A combination of these forms provides broader antioxidant support compared to a single form alone. As a fat-soluble vitamin, delivering vitamin E in an oil-based form supports its natural absorption (Quigley, 2021).

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).

L-cysteine is a sulfur-containing amino acid that plays an important role in cellular metabolism and antioxidant defense. It is a key precursor for the synthesis of glutathione, one of the body’s most important intracellular antioxidants.

Glutathione participates in biochemical pathways involved in protecting cells from oxidative stress and supporting normal detoxification processes. Because the liver plays a central role in these metabolic pathways, nutrients involved in glutathione synthesis are often included in nutritional strategies aimed at supporting liver function and metabolic balance.

In animals exposed to environmental stressors, dietary changes, or recovery from illness, maintaining adequate antioxidant capacity can help support normal physiological resilience and cellular health.

Broccoli and especially broccoli sprouts provide precursors to sulforaphane, a plant compound known for activating the body’s natural “cell protection” systems. This matters for longevity support because sulforaphane helps switch on pathways linked to healthy aging, including antioxidant defenses and normal cell repair processes. 

It can also support hormonal health indirectly by promoting healthy liver detox activity, which is important for how the body processes and clears hormones. In animals, research has shown that sulforaphane from broccoli sprout supplements is absorbed and converted into measurable metabolites after oral intake, meaning they can actually use these compounds. Curran KM et al., 2018, Kubo E et al., 2017; Verhelst, 2025

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.

Linseed is valued for alpha-linolenic acid (aplantomega-3) and is commonly used in horses and dogs to support healthy skin andcoat. It is especially relevant when animals eatmainly hayor processed diets with less natural omega-3 compared with fresh forage. Linseed also provides gentle mucilage-like fibers that many owners associate with digestive comfort. Sembratowicz et al., 2020
