Vitamin A

Vitamin A has the unique distinction of being the very first vitamin officially named which is why it was given the letter A as it’s identifying marker. Vitamin A prevents night blindness, eye problems, skin disorders such as acne, enhances immunity and is primarily absorbed in the intestine.  Because it is absorbed in the intestines, it may reduce symptoms associated with gastro intestinal ulcers.
Vitamin A is needed for the maintenance and repair of all tissues especially epithelial tissues which skin and mucous membranes are composed of. 
It is important for:

• Bone
• Teeth
• Aids in fat storages
• Protects against colds, flus and infections of kidneys, bladder, lungs and mucous membranes.

Vitamin A acts as an ANTIOXIDANT helping to protect cells against CANCER and other diseases.
It is necessary for:

• growth
• guards against heart disease and stroke,
• lowers cholesterol levels.

Deficiencies include:

• Dry hair, skin and eyes
• Abscesses in ears
• Insomnia
• Fatigue
• Reproductive issues
• Sinusitis
• Pneumonia
• Frequent colds

The best way to improve your intake of vitamin A is by adding real food that are high in vitamin A. 
​
Antibiotics, laxatives and some cholesterol lowering drugs interfere with vitamin A absorption.  Approximately 500-10000 IU should be taken by the average adult.  The lower RDA amount of 3000 IU will prevent most deficiency symptoms such as night blindness.
