Glutathione for a Healthier Pregnancy
by: Priya Shah
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:
- Radiation
- Pesticides and
Persistent Organic Pollutants (POPs)
- Air pollution
- Heavy metals
(mercury, cadmium, arsenic)
- Vinyl chloride
- Acryonitrile
- Excess Oxygen (hyperoxia)
- Anti-psychotic
and anti-epileptic drugs (AEDs)
- Thalidomide
- Cigarette smoke
- Alcohol
(ethanol) consumption
Maternal health
factors that increase free radicals and cause birth defects include:
- Diabetes
- Pre-eclampsia
- 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.
