Vitamins play so many various roles in our bodies. They are essential for growth, vitality and health. Vitamins are helpful in digestion, elimination and resistance to disease. Vitamin A is commonly called retinol adopted from the retina where it plays important functions with eyesight.
Vitamin A is absorbed primarily from the small intestine. This fat-soluble vitamin is reduced with alcohol use, with vitamin E deficiency, with cortisone medication, and with excessive iron intake or use of mineral oil, as well as with exercise.
Vitamin A can be stored in the body, primarily the liver (90%) as well as the kidneys, lungs, eyes and fat tissue and needs zinc to help release the storage.
helps maintain a healthy cornea. Deficiency may result in inability to see at night, inflammation and irritation.
- Growth and tissue healing
involved in new cell formation, including bone cells and healthy teeth. After tissue injury, vitamin A is needed for repair and helps to protect the tissues from infection.
- Healthy skin
stimulates growth of the base layer of the skin cells and gives them structural integrity. It does this for both external and internal skin cells and mucous membrane lining (nose, bladder, intestinal tract, respiratory lining, eyes). This helps propel secretions which helps to fight infectious agents and environmental pollutants.
helps protect the body from free radicals in the environment such as smoke and is helpful in preventing ulcers and atherosclerosis.
- Lowers cancer risk and supports immune functions
vitamin A has been shown to optimize function of white blood cells to enhance recognition of food antigens and blocks certain viruses.
A 5000 to 10 000 IU/day should be the average adult intake and is a safe amount to consume. About 10 000 to 20 000 additional IU may be helpful to those with some level of anxiety and stress.
The average American diet consumes 3300 IU making vitamin A deficiencies very common. Deficiencies cause visual changes, dry skin and increased infections. When our stress levels are high, with illness or trauma, if we smoke or live in polluted environments or if pregnant or nursing, our vitamin requirements are higher.
BOTTOM LINE, make sure you are eating your vegetables! Eight to ten servings a day is what I recommend in my nutrition plan. Supplementing with a multi-vitamin is beneficial if you cannot meet these requirements at all times.
I use a women’s multi-vitamin from Prograde Nutrition. This vitamin is perfect for me as it supports hormone balance, increases sleep quality, is composed of 25 whole vegetables plus much more.
Here is an excellent greens product from Athletic Greens. This is one amazing product that has been researched by a close friend of mine and has all positive feedback. I love this product because it supports an active individual and is made up of high quality vegetables without any fillers.
Greens products are super handy when you are on the go or if you are feeling under the weather and need a little more nutrients.
Stay Healthy and Happy!
