Vitamin B6
Studies show that
asthmatic patients have lowered
blood levels of vitamin B6
(pyridoxine). Asthma
sufferers may find supplementary
benefit with the addition of
pyridoxine into the diet, as well
as other B-complex vitamins (2,
3). Numerous studies
report that theophylline-containing
drugs, which are commonly used by
asthmatic patients, may contribute
to vitamin B6 deficiency (4-7).
One study in particular
demonstrated that vitamin B6
supplementation can also reduce
the side effects of theophylline (8).
Multiminerals
(Magnesium, Zinc, Calcium,
Potassium, Selenium)
As previously
mentioned, corticosteroids are often
taken by asthmatic patients and
may deplete the body of certain essential
minerals. Supplementation with
minerals such as calcium,
magnesium, potassium, and zinc may
be beneficial for asthmatic
patients (9).
Numerous studies show that
magnesium helps relax bronchial
smooth muscle. Its supplementation
may also result in an improvement in lung
function and a decrease in
adverse symptoms experienced by asthmatic patients (10-15).
Studies have also shown that zinc
and selenium supplementation may
have some therapeutic effect on
these persons (16,
17). One study found that
the intake of selenium has been
declining in European countries
and may be leading to increased
rates of asthma (18).
Essential Fatty
Acids (Fish Oil, Flaxseed Oil)
Numerous studies
show that supplementation with
omega-3 fatty acids such as fish
oil and flaxseed oil provide
certain anti-inflammatory effects, reduce
asthma symptoms, and improve lung
function (19-21).
Antioxidants (Beta_Carotene,
Vitamin E, Vitamin C)
Antioxidants help
protect the lungs against
free-radical damage and
inflammation (22).
Again, many asthma patients
exhibit lower blood
levels of vitamin C and,
therefore, may have a
greater need for vitamin C. Several
studies show that supplementation
with vitamin C improves asthma
symptoms (23,
24). One study found
that vitamin
C, when combined with vitamin E, may help control
asthma symptoms in patients who
are exposed to air pollutants (25).
Flavonoids (Quercetin
and Grapeseed Extract)
Numerous studies
have shown that flavonoids such as
quercetin (a bioflavonoid) and
grapeseed extract have
potent antihistamine effects.
Antihistamines prevent the release of histamines
and other allergy-related
chemicals, including leukotrienes
and prostaglandins (26-30).
Quercetin, or grapeseed extract, taken in combination with vitamin
C has all been found to work
synergistically to assist in the treatment
of specific asthma
symptoms (31).
Vitamin B12
Intramuscular injections
of Vitamin B12 may help
improve asthma symptoms (32).
In particular, clinical study has found that vitamin B12
may be effective in treating
sulfite-sensitive asthma patients
(33).
Tylophora
Asthmatica
The botanical,
Tylophora asthmatica, has been
traditionally used in Ayurvedic
medicine for millennia in the
treatment of asthma and other lung
problems. Studies have shown that
supplementation with both tylophora
leaves and extract are effective
agents
in relieving asthma symptoms.
Tylophora bronchodilator
effects are, however, only short-acting (34,
35).
