Nature of Vitamin A

Vitamin A as a fat-soluble vitamin can exist in two forms which are retinoids and carotenoids. The active forms of vitamin A are called retinoids, and they can be found in animal products including dairy, eggs, and liver. On the other hand, plant-based sources like spinach, carrots, and sweet potatoes contain carotenoids.

For instance, in the form of retinol, the body will transform it into retinal and retinoic acid. Both of these are active forms of vitamin A. Whereas retinoic acid is vital for gene expression, cell differentiation, and immunological function, retinol is essential for vision, growth, and development.

Health Benefits of Vitamin A

1. Healthy vision: A healthy vision requires vitamin A to be maintained. It lowers the risk of age-related macular degeneration and aids in preventing night blindness. When you suffer from night blindness, you will face difficulty seeing in low light conditions.

2. Immune Function: Vitamin A is important for a healthy immune system. It is essential for preserving the health of the epithelial tissues, which serve as the body’s initial line of defense against infection.

3. Development and growth: Vitamin A is crucial for development and growth, particularly in young children. It encourages bone growth, controls skin and hair growth, and aids in maintaining normal reproductive function.

4. Nootropic Effects: Vitamin A has been demonstrated to improve memory, focus, and other aspects of cognition.

Chemistry of Vitamin A

A lengthy isoprenoid side chain and a beta-ionone ring make up the intricate structure of the vitamin A molecule. Retinol is the form of vitamin A that the body takes in and transforms into retinal and retinoic acid. While retinoic acid is essential for immunological function, cell differentiation, and gene expression, retinal is required for vision.

Physiological Mechanism of Action of Vitamin A

Rhodopsin, a protein that is present in the retina of the eye, is made up in part of vitamin A. Rhodopsin is an enzyme found in the eye. It absorbs the light when it enters the eye, causing a signal to be transmitted to the brain and enabling vision. Without vitamin A, the generation of rhodopsin will be inhibited, which leads to visual impairments.

As mentioned, vitamin A is important for both growth and development and it is also required for the epithelial tissues to function properly. The skin, eyes, lungs, and digestive systems are only a few places on the body that are lined with epithelial tissues. Vitamin A supports proper growth and development by maintaining the integrity of these tissues which helps the body’s first line of defense. Thus, vitamin A is crucial for the immune system.

Studies have shown that vitamin A boosts the neurotransmitter, acetylcholine, which results in improved memory, focus, and also other aspects of cognition.

Optimal Dosage of Vitamin A

Men should consume 900 mcg of vitamin A per day, while women should get 700 mcg. The daily recommended dose for vitamin A should not be exceeded because doing so can be harmful to the body.

Side Effects of Vitamin A

Vitamin A toxicity, which can result from excessive ingestion, can produce many symptoms, including nausea, vomiting, headaches, lethargy, dizziness, and skin irritation. More serious symptoms, such as liver damage, bone discomfort, and hair loss, might result from long-term poisoning of vitamin A.

Potential Substance Interactions with Vitamin A

1. Anticoagulant Drugs: When combined with anticoagulants like warfarin, vitamin A can raise the risk of bleeding. If you are using anticoagulant medicine, it is crucial to speak with a healthcare provider before taking vitamin A supplements.

2. Isotretinoin: An acne medicine, isotretinoin is used to treat acne. It is a type of vitamin A. Taking it along with supplements of vitamin A can make the effects due to an overdose of vitamin A more poisonous.

3. Zinc: If consumed in excess, zinc can increase the absorption of vitamin A, which can be hazardous.
