A glutathione
deficiency can have a devastating effect on the nervous system,
causing such symptoms as lack of balance and coordination, mental
disorders, and tremors. Any illness (even a bad cold), chronic
disorders such as asthma and rheumatoid arthritis, injury, or heavy
exposure to pollutants can cause a GSH deficiency. This is because
your body uses more GSH when it is supporting white blood cells and
ridding the body of toxins.
Glutathione is found in almost all fruits and vegetables. Acorn
squash, asparagus, avocado, cantaloupe, grapefruit, okra, orange,
peach, potato, spinach, strawberries, tomato, watermelon, and
zucchini are all good sources of GSH. Some vegetables, such as
broccoli, cabbage, Brussels sprouts, cauliflower, kale, and parsley,
not only provide GSH, but also actually stimulate the body produce
more of this powerful antioxidant. Cooking destroys a lot of the
glutathione in fresh fruits and vegetables, so you can get the most
GSH from these foods by eating them raw or steamed. Eating foods
high in glutamine, such as lean meats, eggs, wheat germ, and whole
grains, can also stimulate the liver to produce more GSH.
There is no Recommended Dietary Allowance (RDA) for GSH, but
supplements have no known harmful side effects. Glutathione
supplements can be expensive, but there is some question about the
body’s ability to absorb GSH efficiently in supplemental form. If
you want to take GSH supplements, just make sure to take them with
meals to maximize absorption.
