Copper toxicity commonly occurs. Copper toxicity
is a very serious medical problem.
Acute toxicity due to
ingestion of too much supplement, for example, may
nausea, vomiting, abdominal pain, diarrhea, dizziness,
headache, and a metallic
in the mouth. Chronic toxicity is often caused by genetic
defects of copper metabolism, such as Wilson's disease.
In this disease, copper is not
eliminated properly & is allowed
to accumulate to toxic levels.
Copper is therefore present at
high concentration where it should not be, such as in the
liver, the lens of the eye, kidneys, or brain. Copper is a good antioxidant. It
works together with an
antioxidant enzyme, superoxide dismutase (SOD), to protect
cell membranes form being destroyed by free radicals.
radicals are any molecules that are missing 1 electron.
Because this is an unbalanced & unstable
state, a radical is
desperately finding ways to complete its pair.
reacts to any nearby molecules to either steal an electron or
away the unpaired 1.
In the process, free radicals
initiate chain reactions that destroy cell structures.
other antioxidants, copper scavenges or cleans up these highly
reactive radicals & changes them into inactive, less harmful
compounds. Therefore, it can help prevent
cancer and many
other degenerative diseases or conditions such as premature
aging, heart disease, autoimmune diseases, arthritis,
cataracts, Alzheimer's disease, or diabetes." One may need to
increase their SOD to increase copper's benefits & to offset
any copper excess.

The most common side effects are cough,
low blood pressure,
dizziness, headache, drowsiness,
diarrhea, abnormal taste sensation (metallic
or salty taste), & rash.
Compared to ACE inhibitors, cough occurs less
often with ARBs. The most serious, but rare, side effects are kidney
failure, liver failure, allergic reactions, a decrease in white blood
cells, & swelling of tissues (angioedema).
ARBs usually are NOT
prescribed for pregnant patients because they may cause birth defects.
Individuals with severe kidney
problems and those who have had a severe
reaction to ARBs probably should AVOID them."
