2.  WHAT IS LACTIC ACID ?
 LACTIC ACID IS ALSO KNOWN AS LACTATE
.IS A SUBSTANCE THE BODY PRODUCES
WHEN YOUR CELLS BREAKDOWN OF
GLUCOSE IN CARBOHYDRATES FOR ENERGY
.
 MUSCLE CELLS AND RED BLOOD CELLS
MAKE THE MOST LACTIC ACID, BUT IT CAN
COME FROM ANY TISSUE IN YOUE BODY .
 LACTIC ACID IS AN ORGANIC ACID. IT HAS
A MOLECULAR FORMULA :C3H6O3

3.  Most people think of lactic acid in their muscles
during a tough workout. Your muscles do produce lots
of lactic acid when you’re exercising, but that’s not
the only activity that can create it. Anything that
makes your body use more oxygen than usual can
cause your cells to produce lactic acid. A workout,
doing yardwork or lugging heavy boxes while you’re
helping a friend move can all cause a short-term
increase in lactic acid in your body. That temporary
rise in lactic acid isn’t dangerous and usually won’t
cause any symptoms. Your liver and kidneys filter
lactic acid out of your blood and break it down into
glucose (blood sugar)

4. SIMPLE TERMS IN LACTIC ACID
 A SUBSTANCE MADE FROM SUGARS IN
MILK ,BY THE ACTION OF CERTAIN ENZYMES
.IT IS USED IN SKIN CARE PRODUCTS .
 REDUCE WRINKLES AND SOFTEN THE
SKIN.
 LACTIC IS ALSO MADE IN MUSCLES IN THE
BODY AND IS USED IN MANY CHEMICAL
PROCESS IN THE BODY.IT IS A TYPE OF
ALPHA HYDROXYL GROUP.
 YOUR MUSCLES TO PRODUCE LOTS OF
LACTIC ACID WHEN YOU,RE EXERCISING.

5. WHERE IS LACTIC IS FOUND ?
 Lactic acid is found in pickled vegetables,
sourdough bread, beer, wine, sauerkraut,
kimchi,(salt fermented vegetables) and
fermented soy foods like soy sauce and
miso (ferment soy). It's responsible for
their tangy flavor (spicy snacks) ( 4 ). In
addition to fermented vegetables and
grains, fermented dairy products like kefir
and yogurt contain lactic acid.

11. WHAT DOES LACTIC ACID DO ?
 Your body usually fuels your muscles with
oxygen (aerobically). If you start doing
intense physical activity faster than your
body can get oxygen to your muscles and
other tissues, your cells break down glucose
to create the energy you need to keep
moving (anaerobically). Lactic acid is created
when you’re generating energy anaerobically.
 Lactic acid has three main functions,
including:
 Energy: Your body makes lactic acid to fuel
cells when they’re working harder than usual.

12.  Generating glucose (gluconeogenesis): Your
liver and kidneys filter lactic acid out of your
blood after it’s created in other tissue. They
break it down and convert it into new glucose
that your body can use for energy in the future.
 Molecular signaling: Lactic acid in your blood is
a signal molecule throughout your body. Think of
it like a set of flags or markers a construction
crew puts down before they begin working in an
area. Lactic acid attracts cells in your immune
system to heal wounds and fight infections.

13.  It’s a common myth that lactic acid makes
your muscles ache or burn after a
workout. Experts used to think a buildup
in lactic acid caused some of the soreness
you feel in the days after intense activity.
But studies have found that lactic acid is
flushed out of your muscles so quickly
that it doesn’t damage your cells or cause
pain.

14.  Usually, the soreness you feel in the days
after a workout is caused by microtears
(tiny tears in your muscle fibers). This can
be a good thing — repairing these
microtears makes muscles grow bigger
and stronger. But if you’re experience
severe muscle pain, you might have an
injury like a pulled muscle (a muscle
strain).

15. LACTIC ACID PRESENT IN BODY ?
 The organs and tissues that produce the
most lactic acid include your:
 Muscles.
 Red blood cells.
 Skin.
 Brain.
 Gastrointestinal tract (your GI tract).
 CONDITIONS AN

16. WHAT IS A HIGH LACTIC ACID
LEVEL ?
 Health conditions and infections that
make it harder for your body to get fresh
oxygen to your cells can raise your lactic
acid levels. This can lead to lactic acidosis
— a dangerously high lactic acid level.
Lactic acidosis is a serious health
condition that can be fatal.
 Lactic acidosis is usually a complication of
other health conditions, including:

17.  Kidney failure.
 (Liver failure.
 Cirrhosis.)
 Heart failure.
 Infections and sepsis. (Bad blood sore)
 Cancer.
 The most common symptoms of lactic
acidosis include:
 Nausea and vomiting.
 Weakness, especially in your muscles.
 Abdominal pain

18. WHAT IS A LACTIC ACID LEVEL
TEST ?
 A lactic acid level test is a blood test. A
healthcare provider will test your lactic acid level
if they think you might have lactic acidosis. Your
provider will send a sample of your blood to a
lab. The lab will check how much lactic acid is in
your blood.
 Having high lactic acid doesn’t automatically
mean you have one of the serious conditions that
causes lactic acidosis, but it’s usually a sign that
your cells aren’t getting enough oxygen. Your
provider will tell you what your results mean and
which treatments you’ll need to lower your lactic
acid level.

20. HOW CAN I TAKE CARE OF MY
MUSCLES ?
 Lactic acid doesn’t cause pain in your
muscles. It also doesn’t cause injuries.
 In general, make sure to stretch and
warm up before starting any intense
physical activity. Increasing your overall
flexibility will help prevent muscle injuries.
The more you work your muscles by
gradually stretching them, the more
flexibility and give they have when you
move.

21. IS LACTIC ACID A BIRTH
CONTROL ?
 A healthcare provider might prescribe
you lactic acid combined with citric acid and
potassium bitartrate as birth control. This is a
vaginal gel that’s specifically formulated to
prevent pregnancy when a person applies it
into their vagina before having vaginal
intercourse.
 This medicine is different than the lactic acid
that your body naturally produces. The
typical, healthy amount of lactic acid in your
body isn’t a form of birth control. It won’t
affect your ability to get pregnant.
