What does it do? Adenosine monophosphate (AMP) is an
intermediary substance formed during the body’s process of creating energy in the form
of adenosine triphosphate (ATP) from food. AMP may play a role in limiting postherpetic
neuralgia, which is the pain that sometimes lingers after a bout of shingles (herpes zoster). One double-blind study involving 32
adults with shingles found that injections of AMP given three times per week for a month
following a flare-up of shingles relieved the pain more quickly than placebo.1
Whether oral supplementation would have the same effect remains unclear. AMP also helps heal
the lesions and prevents recurrence of pain or lesions.
Nineteen out of twenty-one people with porphyria cutanea tarda (a disease that develops in
adulthood and causes photosensitivity, among
other symptoms) responded well to 160–200 mg of AMP per day taken for at least one
month, according to one group of researchers.2 Partial and even complete
alleviation of photosensitivity associated with this condition occurred in several people.
A closely related molecule to AMP, adenosine, affects electrical signaling in the heart.
Intravenous adenosine has been used successfully to treat children with tachycardia, a
condition in which the heart beats too quickly.3 Intravenous adenosine has also
been reported to help most elderly people with tachycardia.4
Adenosine is formed by heart muscle when the oxygen supply is low,5 and it
improves the efficiency of the heart.6 Adenosine has also been reported to improve
the heart’s ability to use blood sugar for energy during stress.7
Where is it found? The body creates AMP within cells during
normal metabolic processes. AMP is also found as a supplement, although it is not widely
available.
Adenosine monophosphate
(AMP) has been used in connection with the following conditions (refer
to the individual health concern for complete information):
Who is likely to be deficient? Preliminary research suggests
that people with herpes simplex or herpes zoster (shingles) infections may have low levels of AMP; however, the
clinical significance of this finding is unclear.8
How much is usually taken? The trials using AMP for photosensitivity have used 160–200 mg of AMP per
day; however, the ideal intake of this supplement has not been determined. Research with shingles has used a special gel form of AMP injected into
muscle; a doctor should be consulted for this form of AMP.
Are there any side effects or interactions? The limited number
of human studies involving oral AMP have not indicated any side effects. However, some
researchers have expressed concern that supplemental intake of AMP could, in theory, increase
levels of adenosine, a substance related to AMP that may interfere with immune function.9 Doctors using AMP injections
report that too-rapid intravenous administration or inadvertent administration of an
intramuscular injection into a vein could cause life-threatening arrhythmias of the
heart.10
At the time of writing, there were no well-known drug interactions
with Adenosine Monophosphate.
