function normally. They include vitamins A, C, D, E, and K, choline,
and the B vitamins (thiamin, riboflavin, niacin, pantothenic-acid,
biotin, vitamin B6, vitamin B12, and folate/folic acid).

6. FUNCTIONS OF VITAMINS
• Physiological functions of vitamins in humans. Improvement of vision, antioxidant,
maintenance of the immune system, maintenance of healthy skin. Energy
production, nucleic acid, protein, sugar and fat metabolism, maintenance of the
immune system, psychological functions.

7. IMPORTANCE OF VITAMINS AND DAILY HAEALTH
• Vitamins are important because they help your body perform various functions,
such as converting food into energy, repairing cellular damage, boosting your
immune system, and making proteins and cells . Without enough vitamins, your
body may suffer from health problems, such as infections, fatigue, and organ failure.

8. FAT AND WATER SOLUBLE VITAMINS
• Vitamin A, E, K and D are fat soluble
vitamins whereas, vitamin B1, B2, B3,
B5,B6, B9, B12, biotic and vitamin C
are watersoluble vitamins.

9. VITAMIN A
Vitamin A is an important vitamin for
maintaining healthy vision and a

cells. Vitamin A deficiency cause
problems with eyesight, night
blindness, and an increased risk of
infection.

essential for a variety of biological
processes.
• Vitamin D is primarily obtained through
exposure to sunlight, though it can also
be supplemented through food or
supplements.
• Vitamin D is important for maintaining
healthy bones and teeth, as well as
boosting immune system function and
regulating calcium and phosphorus levels
in the body.

vegetable oils.
• Vitamin E is essential for a healthy
immune system and reducing

bone health.
• It can also be taken as a dietary
supplement to ensure adequate levels
in the body.

13. VITAMIN C
Vitamin C is a water-soluble vitamin that
helps to fight against infections, support
healthy cell growth and repair tissues. It
also helps to produce collagen and helps
to form blood vessels and ligaments.
Vitamin C is found in many fruits and
vegetables, including oranges, lemons,
limes, grapefruits, peppers, broccoli,
spinach and kale.

14. BIOMEDICAL IMPORTANCE OF VITAMIN B1
• Importance of vitamin B1 can be realized with the
fact that it acts as gate keeper among the
carbohydrate breakdown (less energy step), Krebs
cycle (high energy step) and electron transport chain.
So, this vitamin is central in energy metabolism and
its deficiency can seriously impair the energy
metabolism. Deficiency of vitamin B1 can seriously
affect the nervous system, digestion and heart. Brain
is most energy demanding organ of the body and
resultantly severely impaired by vitamin B1 deficiency.

15. VITAMIN B2
Glutathione is most important antioxidant which
provides anti-oxidative protection to body, and this
antioxidant is recycled in the human body by
vitamin B2. This vitamin promotes iron metabolism
and its deficiency also increase the risk of anemia
as iron is important element for red blood cell
production. Deficiency of this vitamin increase the
risk of migraine headache, iron deficiency anemia,
high homocysteine, congestive heart-failure,
parkinson's disease, cataract and hypertension

16. VITAMIN B3
• Vitamin B3, also known as Niacin, is an
essential nutrient found in many foods.
• It helps the body convert food into energy
and is important for maintaining healthy skin
and tissues.
• It also plays a role in the production of
hormones and enzymes.

17. VITAMIN B12
• Vitamin B12 is an essential nutrient for good
health.
• It helps to produce red blood cells and keep the
nervous system functioning properly.
• It can be found in animal products such as eggs,
dairy, and meat.

18. FOLIC ACID
• Folic acid is also essential for the body, and helps
in the production of DNA and RNA.
• It can be found in dark leafy greens, beans, and
legumes.
• It is also available as a supplement, and is
recommended to be taken daily to ensure
adequate intake

19. BIOTIN
• Biotin, Vitamin B7, is an important nutrient that
helps to break down carbohydrates, proteins, and
fat.
• It can be found in foods such as nuts, eggs, and
whole grains.
• It is also available as a supplement, and should
be taken regularly for optimal health.

20. PYRIODOXINE
• Pyriodoxine, Vitamin B6, is a water-soluble
vitamin that helps with metabolism, nerve
function, and the formation of red blood cells.
• It is found in foods like poultry, fish, bananas,
and potatoes.
• It is also available as a supplement, and should
be taken regularly for optimal health
