Functions: Vitamin A is a fat-soluble vitamin
that helps cell reproduction. It also stimulates
immunity and is needed for formation of some hormones.
It helps you see normally in the dark and promotes the
growth and health of all body cells and tissues. It also
protects against infection by keeping healthy the skin
and tissues in the mouth, stomach, intestines and
respiratory and uro-genital tract, promotes bone growth,
tooth development, and helps maintain healthy skin,
hair, and mucous membranes. It has been shown to be an
effective preventive against measles.
Deficiency problems: Night blindness and other
eye problems; dry, scaly skin, problems with
reproduction, poor bone growth, and weak tooth enamel.
Excess amounts: Can lead to birth defects,
headaches, vomiting, double vision, hair loss, bone
abnormalities and liver damage.

Functions: Vitamin B1/Thiamin is a important
water-soluble vitamin that helps all body cells produce
energy from carbohydrates. It is also essential for the
functioning of the heart, muscles, and nervous system.
Not getting enough thiamine can leave one fatigued and
weak.
Deficiency problems: Alcoholics are frequently
low in thiamin and suffer fatigue, weak muscles and
nerve damage as a result.
Food sources: Whole-grain and enriched grain
products, such as bread, rice, pasta, tortillas,
fortified breakfast cereals, pork, liver and other organ
meats.

Children need .6 to .9 mg of B2/riboflavin per day. |
Functions: Vitamin B2 or riboflavin is a
water-soluble vitamin needed for energy metabolism by
changing tryptophan (an amino acid) into niacin (another
B vitamin), for building tissue, reproduction, red cell
production, and helps maintain good vision.
Deficiency problems: Severely malnourished people
may suffer eye disorders (such as cataracts), dry and
flaky skin, and a sore red tongue.
Excess amounts: No problems have been linked to

VITAMIN B6
(pryidoxine)
1.3 to 1.7 mg for adults - 2 mg for women who are
pregnant or lactating.
Children need between .6 to 1.3 mg. |
Functions: Vitamin B6 is a water-soluble vitamin
which helps the body make proteins, which are then used
to make body cells. It also helps convert tryptophan (an
amino acid) into niacin and serotonin (a brain
chemical). Vitamin B6 also helps produce other body
chemicals such as insulin, hemoglobin and antibodies to
fight infection.
B6 plays a role in the creation of antibodies in the
immune system. It helps maintain normal nerve function
and acts in the formation of red blood cells. It is also
required for the chemical reactions of proteins. The
higher the protein intake, the more need there is for
vitamin B6.
Deficiency problems: can cause dizziness, nausea,
confusion, irritability and convulsions, depression,
nausea, mental convulsions in infants and greasy, flaky
skin.
Excess amounts: Can cause nerve damage.

VITAMIN B9
(folate/folic acid)
At least 400 mcgs for most adults - pregnant women 600
mcgs and breastfeeding women should get at least 500
mcgs.
Children need between 150 to 300 mcg per day. |
Functions: Folate and folic acid are both forms
of B9. Folate occurs naturally in fresh foods, whereas
folic acid is the synthetic form found in supplements.
Your body needs folate to produce red blood cells, as
well as components of the nervous system. It helps in
the formation and creation of DNA and maintaining normal
brain function, and is a critical part of spinal fluid.
It has also been proven to reduce the risk for an
NTD-affected (neural tube defect) pregnancy by 50 to 70
percent. Folic acid is vital for proper cell growth and
development of the embryo. That is why it is important
for a woman to have enough folate/folic acid in her body
both before and during pregnancy. |

VITAMIN
B12
2.4 mcg for adults and 2.6 - 2.8 mcg for women who are
pregnant or lactating.
Children need .9 - 2.4 mcg per day. |
Functions: Vitamin B12 is a water-soluble vitamin
which works with folate to make red blood cells. It also
serves in body cells as a vital part of many body
chemicals and helps the body use fatty acids and some
amino acids.
Like the other B vitamins, vitamin B12 is important for
metabolism. It helps in the formation of red blood cells
and in the maintenance of the central nervous system.
needed for building proteins in the body, red blood
cells, and normal function of nervous tissue
Although the functions of vitamin B12 are numerous,
those important to bodybuilders include carbohydrate
metabolism and maintenance of nervous system tissue (the
spinal cord and nerves that carry signals from the brain
to muscle tissues). Stimulation of muscles via nerves is
a critical step in the contraction, coordination and
growth of muscles.
Vitamin B12 is available only from foods of animal
origin; therefore, it is very important for athletes
following a strict vegetarian diet to consult a
physician about vitamin B12 supplementation. In fact,
B12 shots are popular with countless athletes,
vegetarians and nonvegetarians alike, many of who swear
it helps them perform better.
Deficiency problems: Anemia, fatigue, nerve
damage, a smooth tongue, very sensitive skin. B12
deficiencies may be hidden when extra folate is taken to
treat or prevent anemia. Strict vegetarians who eat no
animal products and their infants are the most likely to
develop vitamin B12 deficiencies. People who do not
absorb vitamin B12 may also be deficient.
Excess amounts: No problems are associated with
excessive intake of vitamin B12.

VITAMIN C
60 mg for adults - 70 mg for women who are pregnant and
95 for those lactating.
Children need between 45 and 50 mg |
Functions: Vitamin C is a water-soluble vitamin
that helps the body absorb iron out of food made from
plant sources. It helps produce the connective tissue
collagen, helps form and repair red blood cells, bones
and other tissues, helps keep capillary walls and blood
vessels firm, protects against bruising, helps maintain
healthy gums and heal cuts and wounds, helps protect
from infection by keeping the immune system healthy.
Deficiency problems: Scurvy, a disease that
causes loose teeth, Excessive bleeding, swollen gums and
improper wound healing. Scurvy is rare in the United
States.
Excess amounts: Vitamin C intake may cause
diarrhea and gastrointestinal discomfort. Use of
supplements can also interfere with tests for blood
sugar level.

VITAMIN D
5 mg for most adults. Between 50 - 70 yrs 10 mg, and
after 70 15 mg.
Children need about 5 mg/day. |
Functions: Vitamin D is a fat-soluble vitamin
that promotes the absorption of calcium and phosphorus
and helps deposit these minerals in bones and teeth to
make them strong.
Vitamin D is known as the "sunshine vitamin"
since it is manufactured by the body after being exposed
to sunshine. Ten to fifteen minutes of good sunshine
three times weekly is adequate to produce the body's
requirement of vitamin D. This means that we don't need
to obtain vitamin D from our diet unless we get very
little sunlight – usually not a problem for children.
Vitamin D is vital to the human body as it promotes
absorption of calcium and magnesium, which are essential
for the normal development of healthy teeth and bones.
It also helps maintain adequate levels of calcium and
phosphorus in the blood.
Vitamin D plays a crucial role in the absorption of
Calcium and Phosphorus. Calcium is necessary for
muscular contraction. If adequate stores of Calcium are
not available in the muscle, full, hard muscular
contractions cannot be sustained. Of course, Calcium is
also needed for the integrity of bones, which must
support increased muscle tissue and provide an anchor
during muscular contraction.
And don't forget about Phosphorus. Phosphorus
helps provide quick, powerful muscular contractions,
which comprise the majority of movements during weight
training. Phosphorus is also required for the synthesis
of ATP (Adenosine Triphosphate), the high energy
molecule used by your muscle cells during contraction.
This nutrient is high in the list since
bodybuilders typically avoid the fat content, e.g.,
dairy foods. Look for vitamin D fortified foods and get
in the habit of drinking at least one glass of low-fat
or nonfat milk per day.
Deficiency problems: Greater risk of osteoporosis
and osteomalacia (softening of the bones). Children can
develop rickets or defective bone growth.
Excess amounts: Can lead to kidney stones or
kidney damage, weak muscles and bones, excessive
bleeding and other problems. Excessive amounts usually
come from supplements, not food or overexposure to
sunlight.

VITAMIN E
30 IU for most adults. Children need between 6-11
mg/day. (1 IU is equal to approximately .75 mg)
Note: some researchers and medical experts believe that
with all of the positive studies using higher doses of
vitamin E, this daily recommended intake is not high
enough. |
Functions: Vitamin E is a fat-soluble vitamin
what works as an antioxidant and, as such, may have a
possible role in protecting against illnesses such as
heart disease and some types of cancer.
protects red blood cells and helps prevent destruction
of vitamin A and C
Like vitamin C, vitamin E plays a significant role as an
antioxidant, thereby protecting body tissue from the
damage of oxidation. It is important in the formation of
red blood cells and the use of vitamin K. Many women
also use it to help minimize the appearance of wrinkles,
and mothers use it to help heal minor wounds without
scarring, as it is valued for its ability to soothe and
heal broken or stressed skin tissue.
Vitamin E is a powerful antioxidant, meaning it protects
the cell's membranes. This is important because many of
the metabolic processes that take place in the body,
including the recuperation and growth of muscle cells,
are dependent upon health cell membranes.
You've probably heard a lot about antioxidants in
the news lately, and research continues to validate
their importance. Specifically, antioxidants help to
reduce the number of free radicals in the body. Free
radicals are natural byproducts of cellular respiration,
but accumulation of free radicals can lead to cellular
changes and destruction (even cancer), rendering cells
unable to adapt normally. This means a reduction in
exercise induced processes in the cell such as repair
and growth.
Deficiency problems: Nervous system problems.
Deficiencies are very rare, as vitamin E is abundant in
foods. Premature, very low birthweight babies and people
who do not absorb fat normally may have deficiency
problems.
Excess amounts: May interfere with vitamin K
action and enhance the effect of some anticoagulant
drugs.

VITAMIN K
70-80 micrograms/day for adult males, 60-65 micrograms
per day for adult females.
Children need about half the amount, depending on age. |
Functions: Vitamin K is a fat-soluble vitamin
that is necessary for normal blood clotting and
synthesis of proteins found in plasma, bone, and
kidneys. It regulates blood calcium levels and activates
at least 3 proteins involved in bone health.
Deficiency problems: Thin blood that does not
adequately coagulate.
Note:
Intestinal bacteria produce some of the vitamin K you
need. The best food sources include green leafy
vegetables such as kale, parsley, spinach and broccoli.
Smaller amounts are found in milk and other dairy
products, meat, eggs, cereal, fruits and other
vegetables.
Excess amounts: No symptoms have been observed
from excessive intake of vitamin K.
