Vitamin A for healthy eyes

Vitamin A – Why carrots really do help you to see in the dark

Over the next few weeks, we’ll be exploring in detail how each ingredient in Apsu superfood multivitamin can benefit you, starting at the very top – Vitamin A.

Vitamin A (beta-carotene and palmitate)

Protects eye health // provides immune support // fights inflammation // supports healthy skin and hair growth // helps prevent cancer

We are brought up to believe that eating carrots will make you see at night. In fact, our parents weren’t too far off the truth. A lack of vitamin A can lead to night blindness and vision loss, and carrots are the single best source of beta-carotene, one form of the vitamin, that is found in many colourful fruits and vegetables. Known as “pro vitamin A” carotenoid, plant-based vitamin A has to be digested before it is able to convert into retinol which the body then absorbs. The other form, palmitate, is known as “pre-formed” and is found in meat and dairy products. It is already a retinol so it can be used directly by the body without being converted first.

 

Why Vitamin A is important

Vitamin A is crucial for eye health as well as proper bone growth, healthy skin, and protecting the mucous membranes in our digestive, respiratory and urinary tracts.

A deficiency can, in extreme circumstances, lead to blindness. Without it, the corneas thicken and the condition, known as Keratomalacia, affects both eyes. Symptoms will include night vision loss and extreme dryness of the eyes. The National Eye Institute undertook a study which showed that those who took a multivitamin that included vitamin A, vitamin C, vitamin E, zinc and copper had a 25% reduced risk of macular degeneration over a six year period. Impressive!

A lack of vitamin A can also lead to dry, scaly skin, giving the appearance of premature aging. The process through which the skin thickens and hardens, keratinisation, can also occur inside you, affecting the mucous membranes of your respiratory, intestinal and urinary tracts. It can also help to fight acne, and keeps lines and wrinkles at bay due to the production of collagen. It helps support your body in healing wounds and is a powerful aid in fighting skin cancer.

Respiratory infections are common in those who lack vitamin A. The body’s immunity is impaired and in children the effects are felt particularly badly, with stunted growth and infections common.

And women in their third trimester of pregnancy are at their highest risk of night blindness as the potential for deficiency is particularly acute at this stage.

Many studies have shown the benefits of vitamin A in fighting various forms of cancer due to its ability in controlling malignant cells. Retinoic acid plays a critical role in cell development and differentiation, and it has been shown to suppress lung, prostate, breast, ovarian, bladder, oral and skin cancers.

 

Vitamin A Overdosing

We only put 40% of your recommend daily amount into each serving (two tablets) of Apsu. Whilst it is an incredible vitamin, it is important not to overdose on it and the chances are, if you lead a relatively healthy diet, you will be getting most of it through fruits and vegetables, plus some from meat and dairy.

Overdosing can trigger jaundice, nausea, hair loss, reduced appetite and many other serious side effects.
