Magnesium
Magnesium is an
effective treatment for mild to
moderate hypertension. It
activates cellular processes to
lower the blood pressure.
Magnesium is
most effective in individuals who
exhibit a deficiency of this
mineral. It
also helps to regulate potassium
levels in the body.
In one particular study,
individuals with mild to moderate
hypertension experienced a
systolic decrease by a mean of
2.7 mmHg and a diastolic decrease
by a mean of 3.4 mmHg greater than
placebo. [9]
Calcium
High blood pressure
is linked to low calcium. Individuals with high blood
pressure that respond to salt
restriction, often react better to
the use of supplemental calcium to lower
blood pressure. Calcium mainly
affects systolic pressure, and is very useful in isolated
systolic hypertension.
In a study of
individuals with essential
hypertension, supplementation
caused a 2mmHg reduction in both
the systolic and diastolic
pressures. [10]
Another study concerning elderly
individuals produced a similar reduction.
[11]
Vitamin C
High intake of
vitamin C is correlated with lower
blood pressures. It has a modest
effect on individuals with mild
hypertension. Vitamin C promotes
excretion of lead from the body.
Lead is associated with an
increase in blood pressure.
A study of
individuals with mild hypertension
compared dosages of 500, 1000, and
2000mg of Vitamin C, and its effect
on blood pressure. In the first
month of study, systolic pressure
decreased by a mean of 4.5 mmHg
and the diastolic by a mean of 2.8
mmHg. Although the reduction trend did not
continue, it remained constant throughout
trial period .[12]
In another comparative study of individuals
with isolated systolic
hypertension and essential
hypertension, the systolic
pressure decreased by a mean of 10
mmHg and the diastolic by a mean
of 6 mmHg. [13]
Coenzyme Q10
Coenzyme Q10 is
deficient in 39% of patients with
hypertension, and has been shown
to lower blood pressure by as much
as 10%. [14]
These results, however, do not
appear until 1-3 months of
treatment. CoQ10 is
recommended for use with moderate
hypertension. Coenzyme Q10
also favorably affects the
cholesterol levels and resistance
in the blood vessels of arms and
legs. Its mechanism of
action is not fully understood.
In one study of
individuals with isolated systolic
hypertension, CoQ10 supplementation
resulted in a systolic pressure
decrease of 17.8 mmHg. [15] In another study,
CoQ10 produced a decrease in systolic
pressure by a mean of
6.1 mmHg and decreased the diastolic
pressure by a mean of 3 mmHg. [16]
Omega 3 Fatty Acids
Increased intake of
fish oil and flaxseed oil can
lower blood pressure. Fish oil
has proven more effective than flaxseed
oil in various studies. Although
the mechanism is
not known, it is theorized that
the anti-inflammatory effects of
essential fatty acids produce the
blood pressure lowering effects.
In a study of
individuals with high blood
pressure, supplementation with EPA
and DHA from fish oil for 16 weeks
lead to a reduction in systolic
pressure by a mean of 3.8 mmHg and
diastolic pressure by a mean of 2
mmHg. [17] In another study with omega 3
fatty acids, flaxseed and fish
oils, the systolic pressure
decreased by a mean of 4.1 mmHg
and the diastolic by a mean of 2.4
mmHg. [18]
Another large, population based study,
witnessed a reduction in systolic
pressure (6.4 mmHg) and diastolic
pressures (2.8 mmHg) with the supplementation
of 6g/day of EPA
and DHA rich fish oils. [19]
Crataegus species
(Hawthorne)
Hawthorn is a
well-known botanical medicine for
cardiovascular conditions. It
improves the functioning of the
heart, as well as decreases blood
pressure. It is also a potent
anti-oxidant because of its high flavonoid content. The blood
pressure lowering effects of
Hawthorn are mild, and can take
several weeks to have a noticeable
effect.
In one study
comparing Hawthorn to magnesium
supplementation in individuals
with high blood pressure, a similar
reduction was seen in both groups.
Although the Hawthorn group
exhibited a greater reduction in diastolic pressure than the
systolic. [20]
Allium species
(Garlic)
Garlic has long
been studied for its
cardiovascular effects, especially
concerning lipid reduction.
Garlic is also
effective at lowering one's
overall blood
pressure.
In one clinical
study, a high dose garlic supplementation
given to patients with severe
hypertension decreased systolic
pressure by a mean of 7
mmHg and the diastolic decreased
by a mean of 16 mmHg. These
results were obtained in just five
hours after the initial dosage. [21] In another study of individuals
with isolated diastolic
hypertension, supplementation with
garlic over a 12 week period caused a mean
reduction of diastolic pressure by
11 mmHg. [22]
