Introduction to Vitamins, what are
they?
Our body need nutrients to be healthy. Nutrients are essential for
providing good health and are necessary for many life functions.
Some nutrients we need our body does not make on its own.
So, how do we get them?
We get them from the food we eat and from vitamin
supplements (Nutrition.Gov, 2016).
Supplements are synthetic or natural substances such as fatty
acids, minerals, fiber, or amino acids, among other substances
which you can purchased as pills, tablets, capsules, wafers,
powders, or liquids (Nutrition.Gov, 2016)..
What is the difference between fatsoluble and water-soluble vitamins?

Fat-soluble vitamins are stored in the liver and fatty tissues. These are
not readily excreted from the body.

Water-soluble vitamins travel in the blood and are stored in limited
amounts. These are readily excreted from the body through urine.
Do you need vitamins?
If you take vitamin and mineral supplements daily they can be costly. For some
taking vitamins daily gives them a sense they’re leading a healthier lifestyle.
Recent research studies suggest that supplements aren’t always beneficial and
taking certain vitamin and mineral supplements may even be harmful than good.
This is not to say all vitamins are not good. In fact, some are very good and offer
health benefits. If you have certain health conditions or needs, your doctor may
even suggest adding a supplement to your daily routine. So how do you know
what’s right for you (Health line, 2016)
The best way to find out if you will benefit from vitamins is to talk to your doctor
before taking dietary supplements and If you’re already taking supplements, ask
your doctor should you continue with them especially if you are taking prescribe
medication. Some supplements may interact with medications that you’re taking
(Health line, 2016)
What should I consider before taking a
vitamin supplement?
Do I really need them?
nutritional needs should always be met by eating a variety of foods as outlined in the Dietary
Guidelines for Americans.
Are you pregnant
Women of childbearing age who may become pregnant should be eating food rich in iron-rich plant
foods (like cooked dry beans or spinach) or iron-fortified foods (like fortified cereals) along with
a source of vitamin C. Also pregnant women should be consuming
adequate synthetic folic acid daily from fortified foods. If you are not meeting the RDA recommended
daily allowance for this vitamin you might want to talk with your doctor about supplements
Are you over 50 years’ old
Often older adults have a reduced ability to absorb vitamin B12 from foods. In this case a doctor might
prescribe a supplement.
Are you taking Medication:
Some medication should not be taken with certain types of vitamins. Taking blood thinners, such
as warfarin can be dangerous if you take vitamin K. Taking vitamin K can decrease the effectiveness
of warfarin (Nutrition.Gov, 2016).

Many people do not get enough of vitamin D and have to take
