Transcript of Vitamins, Antioxidants and Bogus Vitamins
WHAT ARE VITAMINS?
Vitamins are organic compounds required in small
amounts for normal growth and functions of humans and
some animals
These are also nutrients needed to fight off diseases
Vitamins cannot be produce by our body and that is why
we must attain them from the foods we eat or through
supplements
QUESTION TIME!
Can Vitamin B12 give you more
energy?
Researchers reviewed more than a
decade’s worth of findings and found
that mega doses of vitamin C doesn’t
prevent colds for most people. Some
studies suggest it might help you get
over the symptoms a little faster. But
it won't make them less severe.
Can Vitamin C ward off a cold?
It's important to get enough B12 since
too little of it can cause anemia,
memory loss, confusion, and tingling in
your arms and legs. But little evidence
shows taking it makes you a better
athlete or gives you more energy. A
diet that includes meat, fish, or dairy
products should be enough for that.

BACK TOVITAMINS
There are 13 vitamins that are essential to your body working well
There are 2 types
Fat-soluble vitamins – stored in your fat cells and requires fat in order to be absorbed
Water-soluble vitamins – these are not stored in your body therefore must be replenished daily
Purpose: Vitamins are used in many different ways inside your body. While vitamins do not directly serve as a
source of energy, they do help the enzymes that generate energy from nutrients such as carbohydrates and fats

Vitamin A Orange colored fruits and vegetables: dark leafy greens (kale)
Vitamin D Fortified milk and dairy products, cereals and suns light
Vitamin E Fortified cereals, leafy green vegetables, seeds and nuts
Vitamin K Dark green leafy vegetables and turnip or beet greens
Water-SolubleVitamin Source
Vitamin B1 (Thiamin) Whole grains, enriched grains, liver, nuts and seeds
Vitamin B2 (Riboflavin) Whole grains, enriched grains and dairy products

Niacin Helps maintain healthy skin and nerves and lowers effect of cholesterol
Folate Needed for production of DNA
Pantothenic Acid Plays a role in the production of hormones and cholesterol
Riboflavin Important for body growth and production of red blood cells
Thiamine Helps body cells change carbs into energy
RECOMMENDATIONS: VITAMIN INTAKE
The Recommended Dietary Allowances (RDAs) for vitamins reflect how much of each vitamin people should get
each day
The amount of vitamins depends on your age and gender. Other factors such as pregnancy and health is also
important
Dietary supplements are another way to get the vitamins you need if the food you eat is not supplying enough
vitamins. Supplements can be helpful during pregnancy and for special medical problems.
If you take supplements, DO NOT take more than 100% of the RDA. Be very careful about taking large amounts
of fat-soluble vitamin supplements -- vitamins A, D, E, and K. Because these vitamins are stored in fat cells, they can
build up in your body and may cause harmful effects.
