Fuel your heart
Feeling tired all the time may be a sign that the body is lacking
in a viatmin-like substance called Coenzyme Q10.
PAUL Lim, 45 years old, works in an advertising firm that requires
him to work long hours and entertain clients in the night. The
constant late nights and lack of sleep causes him to suffer from
brain fog.
How about you? Do you find yourself feeling dull and out of focus
or having difficulty concentrating in any hour of the day? Is your
memory failing you sometimes?
This subtle loss of brain power is a sign of your body running low
on energy.
If you are feeling tired all the time, chances are that your heart
is probably not getting the "fuel" that it needs to be strong and
healthy. This fuel, Coenzyme Q10 (CoQ10), is essential for
production of energy at the cellular level.
Coenzyme Q10, energy, and heart health
Scientists have discovered that your heart contains 10 times more
CoQ10 than any other organ, and it beats 100,000 times a day. None
of these beats could have happened without energy. Therefore, the
heart, being a non-stop working organ, requires a tremendous amount
of continuous energy supply.
Human energy production is a complicated process. The food we eat
is broken down into smaller components in the digestive tract.
These smaller components are then used by the cells to produce
energy. For the cells to convert food to energy, it requires a
vitamin-like substance called Coenzyme Q10 (CoQ10). Without
Coenzyme Q10 our body is unable to make energy.
What causes CoQ10 deficiency
CoQ10 is produced by every cell of the body. The production of
CoQ10 is a 17-step process, which requires at least eight vitamins,
several trace minerals, and the amino acid tyrosine. A deficiency
in any one of the nutrients due to poor dietary intake can hinder
the body's production of CoQ10.
Age can lower your CoQ10 levels. As we age, our body produces less
CoQ10. By the time you reach 50, your heart will be struggling with
half the CoQ10 you had when you were 21.
When that happens, your heart cannot work efficiently, and is not
able to deliver all the oxygen and nutrients needed by the organs,
tissues, and every part of your body. You feel tired and run down.
Intensive exercise can deplete our body's CoQ10. Stress further
exhausts CoQ10 reserves.
Drugs can also cause CoQ10 depletion in the body. An example is the
popular cholesterol-lowering drug family, HMG-CoA Reductase
Inhibitor (statins), which not only lower cholesterol levels, but
also CoQ10. Statins block cholesterol synthesis by inhibiting the
enzyme HMG-CoA reductase. However, this effect is not selective as
it also blocks CoQ10 production.
Studies have shown that CoQ10 depletion from statin use can be
reversed with supplementation. Further, CoQ10 supplementation does
not appear to affect the cholesterol-lowering efficacy of statins.
CoQ10 for healthy cholesterol levels
Researchers have found that not all cholesterols are bad.
Cholesterol can be divided generally into HDL-high density
lipoprotein (good cholesterol) and LDL-low density lipoprotein (bad
cholesterol).
The higher the HDL levels in the blood, the better. LDL is not
really bad but becomes a problem only when it is oxidised by free
radicals. It is the oxidised LDL that builds up in our arteries and
helps to develop the plaque which is characteristic of hardened
arteries.
In the bloodstream, 60% CoQ10 is transported by LDL. CoQ10 protects
LDL from being oxidised by free radicals. Studies have found that
when more CoQ10 is contained in LDL-cholesterol, the less
susceptible it is to oxidation and the less likely it is to form
artery clogging plague.
