Creatine supplementation has been associated with several side effects. While many of these are relatively minor and are not considered life threatening, the potential for serious side effects to occur exists. The side effects associated with Creatine supplementation often vary depending on the individual’s medical condition, dietary intake, and dosage. The more serious side effects are associated with existing medical conditions or long-term use.
Minor side effects are those that often stop once the individual
experiencing them stops taking the Creatine supplement. They
include mild headaches, stomach discomfort, nausea, loss of
appetite, and diarrhea.
Creatine use can also lead to weight gain or increased body
mass. The increase in weight does not disappear as soon as the
individual stops taking the supplement, but he should stop
gaining weight when he does.
Individuals who take Creatine supplements may experience problems sleeping. This can lead to irritability or nervousness. Other side effects associated with the ingestion of Creatine include aggression, depression, dizziness, and fainting. If left untreated, each of these problems can turn into a more serious problem.
According to the Mayo Clinic, certain
individuals may be allergic to Creatine supplements. Signs of an
allergic reaction to this specific supplement include a rash,
itching, or shortness of breath. These symptoms are also associated
with asthma, which is a serious health condition. If you experience
these symptoms while taking Creatine supplements, you should stop
taking them and visit your physician.
Muscle cramps, strains, sprains, and tears can occur when an
individual is taking Creatine supplements. Some studies have
suggested that this is due to an overzealous workout. This type of
injury may be accompanied with dehydration, electrolyte imbalance,
fever, or heat intolerance.
Individuals who have kidney or liver problems should not take
Creatine supplements as this will exacerbate the problem. Underlying
medical conditions can become more pronounced or new problems can
occur. There have been cases of interstitial nephritis, kidney
damage, reported as a result of Creatine use. Other serious side
effects include blood clots in the legs, swollen limbs, seizures,
and abnormal heart rhythm.
Diabetics and those individuals with hypoglycemia should not take
Creatine supplements at all. The intake of Creatine can seriously
affect or alter the processes associated with insulin. Therefore,
individuals who take any drugs or supplements that influence blood
sugar should also refrain from taking Creatine.
