Vitamin A is one the four fat-soluble vitamins that
is absorbed from the digestive tract and bound to lipids (fats). Vitamin A is critical
for human growth and development because it plays an important role in bone development.
Since, vitamin A is stored in the body any excess intake of vitamin A could
lead to potential toxic effects in the human body. Also, a vitamin A deficiency
could lead to several potential side effects as well. Some of these side
effects may include: decreased growth rate, diminished ability to fight
infectious diseases and slow bone development.
Several studies suggest that males between the ages
19-50 should consume 900mg of vitamin A per day, while females between the ages
19-50 should consume 700mg per day. Anything above or below this could lead to
potential harmful effects on the human body.
Some foods that are a good source of vitamin A
include: sweet potatoes, lettuce, red peppers and various herbs (parsley,
basal). If you do not eat a lot of vegetables or foods that contain vitamin A,
you may want to consider taking a vitamin A supplement. This will ensure you’re
getting your daily recommended intake of vitamin A.
