Compatibility Guidelines
| Category | Examples | Best Practice |
|---|---|---|
| Vitamins | Vitamin E, B1 (Thiamine) | Add after fat-soluble vitamins |
| Minerals | Organic selenium, Mn oxide | No redox interaction in dry premixes |
| Antioxidants | Ethoxyquin, Rosemary extract | Synergistic oxidative protection |
| Acidifiers | Fumaric acid (pH 5–6.5) | Maintains optimal phosphate stability |
| Category | Examples | Best Practice |
|---|---|---|
| Minerals | High-dose ferrous sulfate (>300 ppm) | Avoid co-formulation; catalyzes phosphate hydrolysis |
| Binders | Alkaline binders (pH >8.5) | Avoid co-formulation; gradual dephosphorylation over 14 days |

Frequently Asked Questions
Q1. What are the advantages of L-Ascorbic Acid-2-Phosphate over regular Vitamin C in feed?
This stabilized Vitamin C derivative provides enhanced heat and pH stability, retaining over 90% activity under pelleting conditions (85°C for 3 minutes). It is ideal for species requiring long-term antioxidant support, such as poultry under heat stress and aquaculture in high-oxygen environments.
Q2. How stable is this product during feed processing and storage?
It maintains 95% activity after pelleting at 90°C for 2 minutes. It is stable in pH range 3–8, outperforming regular ascorbic acid in alkaline premixes, and features a 50% slower oxidation rate compared to unprotected Vitamin C.
Q3. Is it compatible with choline chloride, trace minerals, or antibiotics?
It is compatible with Choline chloride (<50%) without causing hygroscopic clumping due to the protective phosphate coating, and with Zinc oxide or Copper proteinate (no redox reaction in neutral pH). However, it is incompatible with high-dose ferrous sulfate (>300 ppm) which catalyzes phosphate hydrolysis, and alkaline binders (pH >8.5) which lead to gradual dephosphorylation.
Q4. What is the recommended dosage for aquaculture and livestock?
For aquatic feed (fish, shrimp, crab), the recommended dosage is 0.5–1.0 kg per metric ton of feed. For livestock and poultry feed (or stress relief), the recommended dosage is 0.2–0.5 kg per metric ton. Dosage should be adjusted based on species requirements or veterinary advice.
Q5. How should this Vitamin C derivative be stored to ensure a 24-month shelf life?
It should be stored in a cool, dry, and well-ventilated area, protected from light. Opened packages must be resealed immediately and used promptly to prevent degradation.
Q6. What compliance standards does this product meet?
This product is manufactured in strict compliance with the GB 7300.201-2019 standards, ensuring consistent quality and safety for feed applications.
