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.
