## 解决方案

1. ```
   Use only fish oil packaged in dark glass bottles with nitrogen flush (or single-dose capsules). Check for rancidity by smelling: if it smells like paint or old fish, discard. Example: Nordic Naturals Pet Omega-3 (nitrogen-flushed).
   ```
2. ```
   Add vitamin E supplement at 1 IU per 1 g of fish oil given, using a high-quality d-alpha-tocopherol product. Example: give 400 IU vitamin E with 4000 mg fish oil daily.
   ```
3. ```
   Switch to a more stable omega-3 source like green-lipped mussel powder or krill oil, which have natural antioxidants and lower oxidation risk
   ```

## 无效尝试

- **** — Clear plastic doesn't block light, and refrigeration doesn't prevent oxidation once the bottle is opened; oxygen still enters (70% 失败率)
- **** — More rancid oil means more oxidative stress, worsening the vitamin E deficiency and increasing toxicity risk (90% 失败率)
- **** — Vitamin E must be given in precise ratio (typically 1 IU per 1 g fish oil) and timing; random dosing can be ineffective or cause hypervitaminosis (60% 失败率)
