Cystine is a sulfur-containing
amino acid that helps form healthy skin, hair, bones, and
connective tissue. It is also required to make glutathione, one of
the natural antioxidants that fight free-radical damage
(glutathione detoxifies the liver). Each molecule of
cystine is made from two molecules of cysteine,
another sulfur-containing amino acid that, as its name suggests, is
very similar to cystine; in fact, cystine is generally regarded as
the more stable form of cysteine, although both amino acids can be
converted into the other as needed.
Cystine works closely with
glutathione to remove toxins from the liver. In fact, cysteine is
often used in emergency rooms to treat acetaminophen overdoses,
which are known to cause liver damage. It also protects the liver
and brain against toxins absorbed from alcohol and cigarette use,
and may be effective in preventing hangovers.
There is a lot of cystine in
alpha-keratin, the protein that makes up the fingernails, skin, and
hair. For this reason cysteine supplements are sometimes marketed
as anti-aging products that claim to stimulate the formation of
collagen and improve skin elasticity. Cysteine supplementation may
also help speed the healing of burns and wounds, and improve joint
flexibility in those with rheumatoid arthritis.
Because it promotes the production of
the antioxidant glutathione, cysteine supplementation may be useful
to those suffering from conditions that have been linked to
free-radical oxidative damage, such as hardening of the arteries
and cancer. It may also help treat emphysema, tuberculosis, and
bronchitis ysteine has been shown to help break down mucus in the
respiratory tract.
Cystine is a nonessential amino acid,
which means the body manufactures its own supply of this substance.
However, foods such as eggs, meat, dairy products, and whole grains
are also good sources of cystine.
Cysteine is more easily absorbed by
the body than cystine, so most supplements contain cysteine rather
than cystine. In addition, too much cystine in the body can cause
cystinosis, a rare disease that can cause cystine crystals to form
in the body and produce bladder or kidney stones. This side effect
has not been associated with cysteine; however, as previously
mentioned, cysteine is unstable, and is often converted to cystine
in the body. To avoid the conversion of cysteine to potentially
harmful amounts of cystine, it is advised that you take vitamin C
supplements or consume citrus fruits along with cysteine
supplements. Cystine cannot be used by the body without adequate
amounts of vitamin B6, vitamin B*2, and folic acid, so you l want
to make sure you get the right amount of these supplements as well.
B vitamins are also needed to help the body get rid of
homocysteine, a waste product that is formed when the body uses
cysteine. Homocysteine has been linked to inflammation in the
arteries that results in heart disease.
If you want to try cysteine
supplements, try N-acetyl-cysteine (NAC), which is made naturally
from cysteine, and is better absorbed than other cysteine or
cystine supplements.
