How Vitamin A Supports Your Vision and Immunity
Vitamin A is perhaps best known for its role in eye health. It is a key component of rhodopsin, a protein in the retina that allows you to see in low light. Adequate intake also helps maintain the health of the cornea and other eye tissues.
-
Supports normal vision: Vitamin A helps preserve night vision and overall eye function.
-
Contributes to the normal function of the immune system: It supports the production and activity of white blood cells and maintains the integrity of mucosal barriers.
-
Contributes to the maintenance of normal skin: Vitamin A is involved in skin cell production and repair, helping maintain a healthy complexion.
-
Contributes to the process of cell specialisation: It plays a role in cell differentiation and growth, which is vital for tissue maintenance.
Why Your Body Needs Vitamin A
Vitamin A is a fat-soluble nutrient that plays a critical role in multiple bodily functions. It is essential for maintaining healthy vision, supporting the immune system, and promoting normal cellular growth. Unlike some vitamins your body can produce, vitamin A must be obtained from diet or supplementation. Pure Encapsulations Vitamin A provides 3,000 µg of preformed vitamin A as retinyl palmitate sourced from Norwegian cod liver oil. This form is highly bioavailable, meaning your body can use it efficiently without needing to convert it from plant sources.
The Difference Between Retinol and Beta-Carotene
Vitamin A comes in two main dietary forms: preformed vitamin A (retinol and retinyl esters) and provitamin A carotenoids (like beta-carotene). Preformed vitamin A is found in animal products such as cod liver oil and is directly usable by the body. Beta-carotene from plants must be converted to retinol, a process that varies greatly between individuals. Pure Encapsulations use retinyl palmitate from cod liver oil, ensuring consistent potency and bioavailability. This is especially beneficial for those with conversion inefficiencies, such as people with certain genetic variations or digestive conditions.
Recommended Vitamin A Intake for UK Adults
The European Food Safety Authority (EFSA) recommends a daily intake of 800 µg for men and 700 µg for women. Pregnant and lactating women may need slightly more. The Tolerable Upper Intake Level (UL) for preformed vitamin A is 3,000 µg per day for adults. Pure Encapsulations provides 3,000 µg per softgel, which meets the RDA for most adults without exceeding the UL. As with any supplement, it is important to consider your total intake from food and other supplements. Consult your health care provider to determine the right dosage for your individual needs, especially if you are pregnant, nursing, or taking medications.

Frequently Asked Questions About Vitamin A
Can I take this with other vitamin A supplements?
Because this product supplies the full UL of preformed vitamin A, avoid combining it with other high-dose vitamin A supplements unless directed by a health care professional.
Is this suitable for vegetarians?
This supplement is derived from cod liver oil, so it is not suitable for vegetarians or vegans. Look for a beta-carotene-based alternative if you prefer a plant-based option.
Does this contain vitamin D?
Cod liver oil naturally contains vitamin D, but the amount in this product is minimal and not standardised. Check the label for specifics.
Safety and Potential Side Effects
Vitamin A is safe when taken within recommended limits. However, excessive intake of preformed vitamin A (above 3,000 µg per day) can lead to toxicity, causing symptoms like nausea, dizziness, and liver damage over time. Because cod liver oil also contains vitamin D and omega-3s, consider your total intake from all sources. This product is not intended for long-term use at doses above the UL without medical supervision. If you are pregnant, planning to become pregnant, or have liver disease, consult your doctor before use. Keep out of reach of children.
