Stabilised Vitamin E | Raw Ingredients | BTAqua RAW INGREDIENT STABILISED VITAMIN E A potent fat-soluble antioxidant delivering stabilised alpha-tocopherol for cellular protection, immune competence, reproductive performance, and stress resilience across all aquatic species. AntioxidantCellular Protection ImmuneDisease Resistance ReproductionFertility & Egg Quality NEW Stabilised Form FEAT Fat-Soluble Antioxidant COLD Essential Vitamin ✓ Stabilised Alpha-Tocopherol ✓ Fat-Soluble Antioxidant ✓ Immune & Reproductive Health ✓ Lab-Verified Potency Stabilised Vitamin E is a premium feed-grade alpha-tocopherol acetate designed specifically for aquaculture and aquarium applications. Unlike unstabilised forms that degrade rapidly during feed processing and storage, this esterified form resists oxidation while remaining fully bioavailable after ingestion. Vitamin E is an essential micronutrient that fish and crustaceans cannot synthesise — it must be supplied through the diet. The Vitamin E Difference Why Professionals Choose Stabilised Vitamin E ◆ Stabilised Alpha-Tocopherol Acetate The acetate ester form resists oxidation during feed manufacturing, storage, and in the gut before absorption — ensuring consistent potency from factory to fish. ◈ Cellular Membrane Protection As the body's primary lipid-soluble antioxidant, vitamin E integrates into cell membranes, neutralising free radicals and preventing lipid peroxidation that damages tissues. ◇ Beyond Basic Nutrition Vitamin E functions extend far beyond antioxidant activity — it modulates immune gene expression, reproductive hormone synthesis, and stress response pathways at the molecular level. Key Benefits Engineered for Performance Stabilised Vitamin E delivers measurable benefits across immune function, reproduction, stress tolerance, and feed quality — backed by decades of aquaculture research. Immune System Enhancement Supports antibody production, phagocytic activity, and complement system function, improving disease resistance against bacterial and viral pathogens. Reproductive Performance Critical for gonadal development, egg quality, fertilisation rates, and larval survival. Adequate vitamin E improves fecundity across finfish and crustacean species. Stress Tolerance Protects against oxidative stress from handling, transport, temperature fluctuations, and high stocking densities, reducing mortality during critical periods. Flesh Quality Preservation Delays post-mortem lipid oxidation in fillets, extending shelf life and maintaining sensory quality — important for marketable fish. Selenium Synergy Works in concert with selenium-dependent glutathione peroxidase to create a comprehensive antioxidant defence network within cells. Feed Stability The stabilised form survives extrusion, pelleting, and long-term storage without significant potency loss, ensuring delivered nutrition matches formulated levels. How To Use Quick Use Guide Follow these steps to incorporate Stabilised Vitamin E into your feed formulation for optimal potency and distribution. 01 ▸ Calculate Requirement Typical supplementation rates: 100–500 mg/kg feed for grow-out; 500–1000 mg/kg for broodstock and stress conditions. 02 ▹ Pre-Mix with Oil Disperse in a small amount of dietary oil before blending with dry ingredients to ensure even distribution throughout the feed matrix. 03 ⟐ Add During Mixing Incorporate during the pre-mix stage before pelleting or extrusion to maximise retention and minimise processing losses. 04 ◆ Store Correctly Keep sealed in a cool, dark environment. Minimise exposure to oxygen and light to preserve potency throughout the shelf life. Applications Uses for Aquarium & Aquaculture Stabilised Vitamin E serves critical roles across the full spectrum of aquatic animal husbandry — from broodstock conditioning to grow-out feeds and ornamental species nutrition. ▸ Broodstock conditioning diets — improves egg quality and larval viability for enhanced hatch rates and fry survival. ▸ Grow-out feeds — supports immune function and growth performance during the critical production phase. ▸ Stress mitigation — use before and after transport, grading, or handling events to reduce oxidative mortality. ▸ Ornamental fish foods — enhances colour vibrancy and disease resistance in display and hobby species. ▸ Larval and fry feeds — supports developmental antioxidant protection during the most vulnerable life stages. ▸ Shrimp maturation diets — improves spawning frequency and nauplii quality in penaeid and freshwater prawn species. ▸ Coldwater species — protects membrane fluidity in fish raised at low temperatures where lipid peroxidation risk increases.

The acetate ester form provides superior stability during feed processing and storage. Once consumed, intestinal esterases cleave the acetate group, releasing free alpha-tocopherol for absorption. This ensures consistent, predictable potency. Q What are the signs of vitamin E deficiency in fish? Deficiency symptoms include muscular dystrophy, reduced growth, anaemia, exophthalmia (pop-eye), poor reproductive performance, and increased mortality under stress. Many commercial feeds require supplementation to prevent subclinical deficiency. Q Can this be used in conjunction with other antioxidants? Yes. Vitamin E works synergistically with selenium, vitamin C, and carotenoids like astaxanthin. The combination provides broader antioxidant protection than any single compound alone. Q Is stabilised vitamin E suitable for shrimp feeds? Absolutely. Shrimp have a high dietary requirement for vitamin E, particularly during maturation and larval development. Supplementation improves spawning frequency and nauplii quality. Q How should I store Stabilised Vitamin E long-term? Store in a cool, dry, dark environment. Keep the container tightly sealed to minimise oxygen exposure. Under proper storage, potency is maintained for 24 months. Not Sure Which Supplement You Need?
