Essential Nutrients to Take Care of Your Eyes
Vitamin A, also known as a retinol, has an essential role to play in our vision, immune system and cell growth.
Vitamin A can be found in either animal or dairy products as preformed vitamin A, referred to as retinyl ester. It can also be found in plant based products as carotenoids1.
How does beta-carotene and vitamin A support eye health?
Our bodies convert beta-carotene into vitamin A which is a precursor of vitamin A. While beta-carotene isn’t an essential nutrient vitamin A is. Vitamin A is involved with maintaining the conjunctival membranes, cornea and rhodopsin (a protein that absorbs light) in the eyes making it vital for our eye health2.
How is vitamin A absorbed in the body?
Your body is able to intake vitamin A by directly consuming good sources including cheese, eggs, oily fish, milk, yoghurt and liver products such as liver pâté. However, it is important to try and limit your intake of these liver based products as you may be at risk of having too much vitamin A.
Your body is also able to convert good sources of beta-carotene into vitamin A. Main sources of beta-carotene include; yellow, red and green leafy vegetables such as spinach and carrots or yellow fruit such as mango, papaya and apricots.
To top up vitamin A levels try Simply Timeless Cod Liver Oil Plus Multivitamins capsules which helps to maintain good health as you get older and include DHA, and vitamin A to support the maintenance of normal vision.
If you’re pregnant or trying for a baby always read the label and consult your doctor before taking supplements containing Vitamin A, as they can be harmful to your unborn baby3.
How much Vitamin A do I need?
It’s important to know that your body is able to store vitamin A and use it at a later date.
The recommended daily amount of vitamin A in adults aged between 19 – 64 years is
800mg a day for both men and women3.
What happens if I have too much vitamin A?
Ingesting over the recommended daily amount of vitamin A may affect your bones which can cause them to fracture when you’re older. In particular, if you eat liver or liver pâté more than once a week, you may be getting too much vitamin A.
How else can I protect my eyes?
It’s important to ensure you have regular eye tests to detect any health problems or changes in vision. Remember to always protect your eyes when out in the sun by wearing sunglasses and avoiding looking into the sunlight directly.
