Gingerols with antioxidant/anti-inflammatory properties; traditionally for joints and digestion.
Turmeric
Curcuma longa
Curcumin with antioxidant/anti-inflammatory properties; low oral bioavailability.
Valerian
Valeriana officinalis
Calming valerenic acid; listed as a prohibited substance under FEI rules.
Ribwort plantain
Plantago lanceolata
Mucilage and iridoids; traditionally to soothe the airways.
Thyme
Thymus vulgaris
Essential oils (thymol); traditionally secretolytic/airway-supporting.
Chamomile
Matricaria chamomilla
Bisabolol and flavonoids; traditionally soothing for the GI tract and skin.
Chondroitin sulfate
Chondroitin
Cartilage-matrix glycosaminoglycan; often combined with glucosamine.
Hyaluronic acid
Hyaluronan
Component of joint fluid and cartilage; oral debated, established mainly intra-articular (veterinary).
Green-lipped mussel
Perna canaliculus
Provides glycosaminoglycans and omega-3 fatty acids (ETA); discussed to support the locomotor system.
Algae oil
Schizochytrium
Plant-based direct source of long-chain omega-3 fatty acids (DHA/EPA) without conversion loss.
Salmon oil
Fish oil
Marine source of long-chain omega-3 fatty acids (DHA/EPA).
Lactobacillus
Lactic acid bacteria
Lactic-acid-producing bacteria; discussed to stabilise the gut flora.
Spirulina
Arthrospira platensis
Nutrient-dense blue-green alga; discussed for immune/allergy modulation (e.g. sweet itch).
Rosehip
Rosa canina
Rich in vitamin C and polyphenols; a galactolipid (GOPO) studied for joint comfort.
Gamma-oryzanol
Rice bran extract
Rice-bran sterol esters; popular for muscle/condition support — evidence limited.
L-Tryptophan
Trp
Essential amino acid and precursor of serotonin. Used in calming supplements, but the evidence for a sedative effect in horses is contradictory.
Thiamine (Vitamin B1)
Thiamine hydrochloride
Water-soluble B vitamin and coenzyme in carbohydrate and nerve metabolism. Included in calming products for its role in normal nerve function.
Passionflower
Passiflora incarnata
Traditional medicinal plant with flavonoids, attributed a calming, GABAergic-modulating effect. Horse-specific studies are largely lacking.
Hops
Humulus lupulus
Medicinal plant with bitter compounds (incl. 2-methyl-3-buten-2-ol), attributed a calming, sleep-promoting effect. Equine data are sparse.
Lavender
Lavandula angustifolia
Medicinal plant whose essential oil (linalool, linalyl acetate) shows a short-term stress-reducing effect in horses via inhalation/aromatherapy. Oral evidence is weaker.

Ashwagandha
Withania somnifera
Ayurvedic adaptogen with withanolides, attributed stress- and cortisol-modulating properties. Horse-specific evidence is largely lacking.
Taurine

Sulfur-containing aminosulfonic acid with roles in membrane stabilisation and neuromodulation. Added to calming products; oral calming evidence in horses is lacking.
GABA (gamma-aminobutyric acid)
