Glutathione
for a Healthier Pregnancy

All parents-to-be
nurture the dream of a healthy pregnancy and baby.
But the
modern environment and diet is deficient in many factors essential for
the health of mother and fetus. One of those factors is antioxidants.
The role
of antioxidants like folic acid in preventing birth defects like spina
bifida and cleft palate is well known. It is now included in all prenatal
vitamin supplements.
But the
role of antioxidants like glutathione and Vitamin E in pregnancy is
often overlooked.
Antioxidants
and glutathione status play an important role in the development and
growth of the fetus, maintenance of a healthy pregnancy - and even before
pregnancy, in fertility and conception.
Glutathione
is the body's master antioxidant. It helps to regenerate stores of other
antioxidants like Vitamin C and E.
It also
protects both mother and fetus from the damaging effects of free radicals
and oxidative stress.
Many pregnancy
complications and birth defects have been linked to oxidative stress,
free radical damage and low glutathione levels in the mother and fetus.
The role
of glutathione in the development of the foetus and placenta is crucial.
Glutathione (GSH) can control cell differentiation, proliferation, and
cell death - essential functions in the developing embryo.
In the
placenta, glutathione detoxifies pollutants before they reach the developing
child. Most substances or factors which cause birth defects (teratogens)
are known to exert their embryotoxic effects because they cause oxidative
stress.
The human
placenta possesses a significant amount of glutathione S-transferase
(GST) capable of detoxification or activation of drugs and pharmaceuticals
during the critical period of organ development in the fetus.
Some drugs
are known to cause birth defects in the growing fetus by generating
free radicals, and depleting GSH stores.
In the
early embryonic stages, the fetus is sensitive to the toxic and teratogenic
effects of chemicals, whereas it is sensitive to carcinogenic effects
during late fetal stages.
Carcinogens
administered to the mother can be transferred through the placenta and
induce cancer in the fetus. Many carcinogens are much more active in
the fetus than in adults and they tend to act as abortifacients and
teratogens as well.
Environmental
and lifestyle factors are known to cause oxidative stress and lower
glutathione levels - resulting in birth defects, abortion and miscarriages
in pregnancy.
Some of
the known teratogens (causing birth defects) in pregnancy include:
o Radiation
o Pesticides and Persistent Organic Pollutants (POPs)
o Air pollution
o Heavy metals (mercury, cadmium, arsenic)
o Vinyl chloride
o Acryonitrile
o Excess Oxygen (hyperoxia)
o Anti-psychotic and anti-epileptic drugs (AEDs)
o Thalidomide
o Cigarette smoke
o Alcohol (ethanol) consumption
Maternal
health factors that increase free radicals and cause birth defects include:
o Diabetes
o Pre-Eclampsia
o Infection and Inflammation
Glutathione
and other antioxidants attenuate oxidative stress in pregnant women
with inflammation or maternal conditions like diabetes and pre-eclampsia,
and in fetuses at risk for developing cystic fibrosis.
Supplementation
with glutathione precursors and antioxidants can decrease the incidence
of birth defects and protect both mothers and the fetus from the damaging
and possibly fatal consequences of pregnancy complications.
Glutathione
(GSH ) also prevents or minimizes the oxidative stress that occurs during
labor and the birth process.
Perinatal
or birth asphyxia/hypoxia (deprivation of oxygen supply to the brain)
in preterm deliveries and labor can lead to cerebral palsy, respiratory
distress syndrome, irreversible brain injury, and permanent neurological
and intellectual handicaps.
Administration
of the glutathione precursor, N-Acetyl-Cysteine (NAC), to the pregnant
mother partially prevents oxidative stress during the birth process
in premature infants.
Currently,
the American College of Obstetrics and Gynecology advises all pregnant
women to take a prenatal vitamin containing antioxidants.
In addition,
they advise eating lots of fresh fruits and vegetables, the best sources
of antioxidant protection.
