Vitamin A

Vitamin A plays a crucial role in human health and the body’s vital processes.

It supports eye health, stimulates the production and activation of white blood cells, and participates in bone remodeling.

Vitamin A also helps maintain the cells that line the body’s internal surfaces and regulates the growth of dividing cells, promoting reproductive health.

In this article, we will cover everything related to Vitamin A, including its benefits, rich sources, and the effects of its deficiency on the body.

What is Vitamin A?

Vitamin A is often considered a single nutrient, but in reality, it is a group of fat-soluble compounds, including retinol, retinal, and retinyl esters.

Vitamin A exists in two forms in food:

The first type is known as preformed Vitamin A, which is found in the form of retinol and retinyl esters and is found in animal products such as dairy, liver, and fish.

The second form of the vitamin is retinal, and it is found abundantly in plant-based foods such as fruits, vegetables, and oils.

The body converts both forms of Vitamin A into retinoic acid, which is the active form of the vitamin.

The body stores most of its available Vitamin A in the liver as retinyl esters.

Where is Vitamin A found?

Food sources rich in both forms of Vitamin A include:

• Cheese
• Eggs
• Oily fish
• Milk and yogurt
• Animal liver and its products
• Yellow, red, and green (leafy) vegetables, such as spinach, carrots, sweet potatoes, and red peppers.
• Yellow fruits such as mangoes, papayas, and apricots.

Benefits of Vitamin A

Vitamin A benefits health in various ways, including:

• Powerful Antioxidant:

Vitamin A has antioxidant properties, protecting the body from free radicals, which are highly reactive molecules formed during oxygen inhalation and can harm the body by creating oxidative stress.

Oxidative stress is linked to chronic diseases such as diabetes, cancer, heart disease, and cognitive decline.

This is achieved through intravenous vitamin infusions that provide the body with antioxidants.

• Essential for Eye Health and Preventing Macular Degeneration:

Consuming adequate amounts of Vitamin A in the diet helps protect against certain eye diseases, such as age-related macular degeneration.

Studies suggest that higher blood levels of "beta-carotene, "alpha-carotene," and "beta-cryptoxanthin" can reduce the risk of age-related macular degeneration by up to 25%.

This risk reduction is linked to the protection of macular tissues through carotenoid nutrients by lowering oxidative stress levels.

• Protects Against Certain Types of Cancer:

Fruits and vegetables rich in carotenoids help protect the body from certain cancers due to their antioxidant properties.

A study involving more than 10,000 adults found that smokers with the highest blood levels of "alpha-carotene" and "beta-cryptoxanthin" had a 46% and 61% lower risk of dying from lung cancer, compared to non-smokers who consumed the least amounts of these nutrients.

Moreover, lab studies have shown that "retinoids" may prevent the growth of certain cancer cells, such as bladder, breast, and ovarian cancer cells.

• Essential for Fertility and Fetal Growth:

Vitamin A is crucial for reproduction in both males and females as it plays a role in the growth of sperm and eggs.

Vitamin A also plays an important role in supporting placental health, fetal tissue development, and fetal growth.

• Boosts the Immune System:

Vitamin A affects immune health by stimulating responses that protect the body from diseases and infections.

Vitamin A participates in the formation of certain cells, including B-cells and T-cells, which play a central role in immune responses that protect against illnesses.

A deficiency in this nutrient leads to increased levels of pro-inflammatory molecules, which reduce immune system response and function.

Vitamin A for Skin

In the 1980s, Vitamin A was used to treat acne, and over time, its effectiveness in treating many skin conditions has been proven.

Topical treatments rich in Vitamin A are applied to the skin to intensify and stimulate the dermis, the second layer of the skin, to:

• Enhance blood flow, carrying nutrients and oxygen to skin cells.
• Increase the healing rate of wounds and acne scars.
• Exfoliate the skin, making it soft and even in tone.
• Repair the skin's cellular structure, improving protection against UV rays.
• Prevent melanin clumping, thus reducing brown spots or pigmentation.
• Reduce oil production, thereby treating acne.
• Enhance cellular membrane health, improving skin hydration.
• Help eliminate skin cancer lesions.
• Improve intracellular hydration, reducing wrinkles.

Symptoms of Vitamin A Deficiency

A deficiency in Vitamin A can lead to serious health complications.

According to the World Health Organization, not getting enough Vitamin A is the leading cause of preventable blindness in children worldwide.

Vitamin A deficiency also increases the severity and risk of death from infections such as measles and diarrhea.

Additionally, research has found that Vitamin A deficiency increases the risk of anemia and death in pregnant women and negatively affects the fetus by slowing down growth and development.

Less severe symptoms of Vitamin A deficiency include skin issues such as acne and hyperkeratosis (benign bumps that usually appear on the face).

After reviewing the many benefits of Vitamin A, from supporting eye health to boosting immunity and fighting diseases.

As well as its magical role in maintaining youthful skin and slowing aging signs, it is clear how important this vitamin is in our lives.

Getting enough Vitamin A through a balanced diet is the first step to maintaining good health.

However, some individuals may need dietary supplements to meet their needs, which is why we recommend browsing evercare’s intravenous vitamin range to compensate for any deficiencies in essential body vitamins.
