5. How much caffeine is too much? As the world becomes more and
more over-caffeinated,thequestion is how much caffeine is too
much?And the answer isthat it depends on the individual and how
sensitive they are tothe drug. Caffeine sensitivity is basically
determined by our body and how efcient it is in processing and
metabolizing the drug.Each person is different.Some people are
moresensitive than others and can't even drink a sodawithout having
a serious reaction.Others can drinkcoffee and then fall fast
asleep.According to theexperts,people need to know how sensitive
they areto caffeine and be aware if it may have any adverse
effects. sprayalleco - lrlog. spraya| |e. co
6. The genetic linkWhen we drink a beverage or eat food
containing caffeine.the drug is metabolized by our liver using a
special enzyme,CYP1A2 which is regulated by the CYP1A2 gene.Each of
us has a slightly different version of this gene and the
differences determine how effectively we can metabolize caffeine
and eliminate from our body.Some people genetically produce large
amounts of the enzyme while others produce only a small amount.with
the average falling in the middle.Caffeine sensitivity is also
affected by the AHR gene by regulating whether the CYP1A2 gene is
turned on or off:and certain types of adenosine receptors also play
a role in our caffeine sensitivity.Based on these factors and
latest genetic data,there appear to be three different levels of
caffeine sensitivity: 0 Hypersensitive 0 Normal 0

7. Hypersensitive to caffeinePeople who are hypersensitive to
caffeine have an immediate reaction to even small amounts of
caffeine.Even when they consume amounts of less than 100 mg,people
who are hypersensitive to caffeine can begin to experience overdose
symptoms.sprayableco - | rlog. spraya| |e. cc
8. Normal Sensitivity to CaffeineClaw 979 "People who have
between 200400mg of caffeine daily.the equivalent of two to four
cups of coffee,show normal sensitivity to caffeine and will suffer
no adverse reactions.These people will usually have no difficulty
sleeping at night if their caffeine is consumed earlier in the day
and not after 2 pm in the afternoon. Most humans fall into this
category.When recommended daily doses are listed on products
containing caffeine,this is the group that the recommended dosage
has been established for.
9. Hyposensitive to CaffeineAround 10% of the human population
is consideredhyposensitive to caffeine.These people can process ' A
caffeine so efciently that they can consume large doses of the
drug, over 500mg,without noticing any effects.Their caffeine
sensitivity is much lower than average and they can usually *1: 2 L
consume products containing caffeine 1 anytime during the day,even
before bedtime,and still have no trouble getting a good night's
sleep.As a result,these L people will usually consume large doses
of caffeine in order to enjoy the benets of caffeine.sprayahleco 0

recommendations are that they be extremely cautious?*-. ,_,,_. r 3%
in consuming the drug.Coffee and energy drinks 5_ X'-_-T; should be
avoided entirely.A wiser choice would 12 ''be to drink green or
black tea,which contain smaller doses of caffeine. People with
normal caffeine sensitivity should also pay attention to how much
caffeine they consume each day.They should be aware that the
recommended safe guidelines are usually considered no more than 300
to 400mg per day,or about two to three cups of regularly brewed
coffee per day.If they are tea drinkers,then drinking seven to
eight cups of green or black tea would be the maximum. People who
are hyposensitive to caffeine should probably question whether
consuming the drug is even a good idea.If large amounts don't
create the desired effect,such as increasing
productivity,wakefulness or alertness,and since caffeine in large
amounts can be toxic,then consuming caffeine at all might not be
considered a good idea. sprayahleso | |log. sprayable. co
11. Outside the guidelinesEven though these caffeine
sensitivity guidelines should apply to almost everyone,there are a
few people who may fall in between levels.For instance,some people
may be normal in most characteristics but lean toward the
hyposensitive or hypersensitive categories.Because of the
complexity of human genetics,some people can have subtle
variations.Also.a few people can become more sensitive to caffeine
over time. While the above guidelines and caffeine sensitivity
levels may apply to many,there are some that could fall somewhere
in the middle. Some people could be normal but lean toward the
hypersensitive category or learn toward the hyposensitive
category.Human genetics are complex and people are unique with many
subtle genetic variations.In addition,some people can develop
caffeine hypersensitivity over time instead of from having it in
their genes.The best thing to do is to see if you seem to t into
the above guidelines.and if in doubt.err on the safe side until you
can determineprecisely your own caffeine sensitivity. sprayablem 0
