Ultra-Sel II Equine Vitamin E & Selenium Powder | Univet Official
Feed Reg No. 820589 Synergistic Anti-Oxidant Matrix

Cellular-level muscle defense, tying-up protection, in a bioavailable daily powder.

Ultra-Sel II pairs high-potency Vitamin E and pharmaceutical-grade Sodium Selenite to neutralize harmful free radicals both inside and outside the muscle cell. Engineered for horses in training, areas with selenium-depleted soils, and athletes prone to muscle stiffness.

Dual-Action Anti-Oxidant Synergy

Ultra-Sel II

Physical exertion creates massive oxidative cascades. When oxygen radicals escape cellular membranes, they rupture muscle fibers, leading to chronic stiffness, delayed recovery, and debilitating “tying up” (exertional rhabdomyolysis). Ultra-Sel II provides targeted replenishment with zero empty fillers.

Vitamin E (Per Dose) 2,000 I.U. 66,667 I.U. / kg (Fat-soluble membrane shield)
Selenium (Per Dose) 1.2 mg 40 mg / kg (Essential for Glutathione Peroxidase)
Synergistic Protection: Protects both cell membranes (Vitamin E) and cytosolic compartments (Selenium).
Guaranteed Palatability: Molasses-scented carrier blends smoothly into grain without sifting out.
Simple Standardized Dosing: 1 scoop (28.4 g) once daily in the feed.
Targeted Indications

Why Equine Athletes Require Dual Antioxidants

Neither nutrient works in isolation. Ultra-Sel II provides the precise biological ratio to protect working tissue.

Tying-Up & Muscle Soreness

Equine exertional rhabdomyolysis causes severe muscle cramping, reluctance to move, and elevated CK/AST enzyme levels. Ultra-Sel II neutralizes lipid peroxides before muscle cell integrity is compromised.

Rapid Membrane Stabilization

Selenium-Deficient Forage

Extensive regions across Canada and the Northern US have notoriously low soil selenium levels. Hay and pasture grown in these areas fail to meet baseline equine requirements, making supplementation critical.

Regional Pasture Defense

Immune Competence

White blood cells and immunoglobulins depend on selenium and Vitamin E to fight off respiratory infections, shipping fever, and viral pathogens encountered during high-density show circuit travel.

Humoral & Cellular Immunity

Nervous System Stability

Selenium deficiencies contribute directly to neurological disorders, jitteriness, and hypersensitivity. Providing stable bioavailable selenite promotes optimal neuromuscular signaling and mental composure.

Frequently Asked Questions

Everything You Need to Know About Ultra-Sel II

Why must Vitamin E and Selenium be given together?

Vitamin E and Selenium perform complementary antioxidant tasks. Vitamin E resides inside the cell’s lipid membrane to scavenge free radicals and stop lipid peroxidation chains. Selenium acts as the mandatory enzymatic cofactor for glutathione peroxidase, an intracellular enzyme that degrades destructive hydrogen peroxide into harmless water. Without adequate selenium, Vitamin E is rapidly overwhelmed, and vice-versa.

How does Ultra-Sel II alleviate equine tying-up (rhabdomyolysis)?

Tying-up is characterized by sudden, painful muscle contractions and breakdown of skeletal muscle cells under heavy exercise or genetic susceptibility (such as PSSM). Ultra-Sel II stabilizes sarcolemmal membranes and reduces myocellular oxidative trauma, allowing muscles to contract and relax smoothly while preventing post-exercise stiffness.

How do I store Ultra-Sel II to preserve antioxidant potency?

Keep the container tightly closed and store in a cool, dry environment away from direct sunlight, excess heat, and humidity. Vitamin E is sensitive to extreme heat and prolonged light exposure, so always reseal the lid after each scoop.

Can picky horses detect the powder in their feed?

No. Ultra-Sel II is engineered with a palatable sweet-tasting carrier designed specifically for equine acceptance. It adheres easily to sweet feed, rolled oats, pellets, or beet pulp without leaving unpalatable powdery residues at the bottom of the feed tub.
