All substances that are ingested by the human body have the potential to cause side effects. Garcinia Cambogia extract has very low instances of side effects no matter the strength that is taken (40%, 50%, or 60% pure extract).
Typical complaints about the supplement range from nausea and stomach discomfort to a mild headache. If taken with a full glass of water 30-60 minutes before a meal, it is very rare that any gastrointestinal affects present themselves. Most instances of nausea or upset stomach are easily remedied by eating a light snack, like crackers.
If taken in excessively large doses or with an SSRI antidepressant, it is possible that too much HCA could build up in the system and cause a serotonin overload. If this happens, patients may experience mood swings, mania, hypomania, fatigue, dizziness, dilated eyes, elevated blood pressure and headaches, tachycardia, fever, muscle spasms, vomiting, muscle weakness, loss of consciousness, vertigo, diarrhea, confusion, shivering and goosebumps, sweating, restlessness, weight gain, or extreme relaxation. Extremely rare overdoses result in lethally high serotonin levels.
It is contraindicated for those with bipolar 2 disorders to take Garcinia Cambogia due to the risk of mania or hypomania with overdose.
