 Vitamin B3 (niacin) has a role in energy production in
cells and helps keep the skin, nervous system, and
digestive system healthy.

5. Benefits cont.
 Vitamin B5 (pantothenic acid) influences normal growth
and development.
 Vitamin B6 (pyridoxine) helps the body break down

the nervous system, and parts of the immune system.
 Vitamin B7 (biotin) helps break down protein and
carbohydrates and helps the body make hormones.

6. Benefits cont.
 Vitamin B9 (folic acid or folate) helps the cells in the
body make and maintain DNA and is important in
producing red blood cells.
 Vitamin B12 (cobalamin) plays a role in the body's
growth and development. It also has a part in
producing blood cells, nervous system function, and
how the body uses folic acid and carbohydrates.
