Summer Is Around The Corner – Time To Get That Shred On
The glorious drug, caffeine, is
frequently used in pre-workout
and fat-burning supplements
to increase energy and focus. It
improves mental alertness, memory,
exercise performance, and fat burning.
So why are they so popular in these
supplements?
Caffeine studies have shown
enhanced peak torque and motor unit
recruitment in lower and upper body
muscle groups. The increase in energy
allows individuals to produce more
power (energy) to squeeze out extra
reps. Muscle burns calories. Caffeine
is a central nervous system stimulant.
It works by stimulating the brain.
There are also plant sources of
caffeine, including kola nuts, guarana,

and yerba mate. You will often see these
last two ingredients when looking at a
thermogenic (fat burner). Caffeine can
be useful and, typically, most people’s
best friend, but it is a drug. It can
cause shakiness, agitation, decreased
coordination, high blood pressure, and
increased heart rate in extremely high
doses. It should be taken with care and
always assess tolerance.
Nitric oxide is a compound that your
body NATURALLY produces to relax
blood vessels and improve blood flow.
It contributes to “the pump.” The pump
is when your muscles swell, caused by
excessive blood.
Some common compounds used to
make nitric oxide are included in preworkout
supplements. These include
L-arginine, L-citrulline, and sources of
dietary nitrates. L-citrulline is an amino
acid found in meat, nuts, legumes,
and watermelon. An example of how
the pump powers growth is through
oxygen.
Increasing the delivery of oxygen-rich
red blood cells to your starving muscles
accelerates the speed at which your
system is able to cleanse itself of muscle
toxins, such as ammonia. It also may
decrease muscle soreness due to the
oxygen-rich blood cells. Nitric oxide is
also crucial for the fat-burning process,
as it facilitates the breakdown of fats.
If nitric oxide levels are low, fat
accumulation increases, leading to
negative impacts on blood flow and

heart health. Moreover, insufficient
nitric oxide can result in a slow
metabolism and hinder weight loss.
So, that last part is critical for those
reading, not necessarily interested in
muscle building or fat burning.
Nitric oxide production is essential
for overall health because it allows
blood, nutrients, and oxygen to travel
to every part of your body effectively
and efficiently. It offers heart-boosting
effects, including reducing arterial
stiffness, reducing blood pressure,
and improving carotid artery blood
flow. Limited nitric oxide production is
associated with heart disease, diabetes,
and a particular “male dysfunction.”
