Increasing your Vitamin A levels safely involves balancing dietary sources and potentially using supplements. Here are some strategies:

1. Dietary Sources:

   • Preformed Vitamin A (Retinol): This is found in animal sources such as eggs and dairy products. Since you're allergic to cod, you might include fortified dairy products and eggs, which are good alternatives¹².
   • Provitamin A (Beta-Carotene): Found in bright-colored fruits and vegetables such as carrots, sweet potatoes, spinach, and kale. These foods are cholesterol-free, making them a good option considering your elevated cholesterol¹³. The body converts beta-carotene into Vitamin A, and it does not pose a risk of toxicity, only a change in skin color if overconsumed⁴.

2. Supplementation:

   • Consider beta-carotene supplements or retinyl palmitate if you choose supplements. Beta-carotene is safer in terms of avoiding toxicity, as it converts to Vitamin A in the body in regulation with its requirements⁵⁶.
   • Be cautious with dosages, especially with retinyl palmitate to avoid toxicity. The recommended dietary allowance for Vitamin A varies, but it's safe not to exceed 10,000 IU of preformed vitamin A daily⁶⁷.

3. Balanced Diet:

   • Opt for a varied and balanced diet that includes both animal and plant sources to naturally boost your Vitamin A levels along with other nutrients⁷.

Considering your specific conditions and dietary restrictions, focusing on plant sources rich in beta-carotene and low-fat animal products could be beneficial. Always consult with a healthcare professional or nutritionist before starting any new supplement regimen to tailor the advice to your individual health needs and to monitor your vitamin levels adequately.
