Atrial flutter reported after Tongkat Ali use in an older man
A case report raises a possible supplement-related heart rhythm concern, while providing no estimate of how often it occurs or proof of causation.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
The report describes atrial flutter that appeared after a man started taking Tongkat Ali. The author considered the supplement a probable trigger because of the timing and the absence of identified alternative causes. This is a signal for further investigation, but a case report cannot establish that the supplement caused the rhythm disturbance.
The abstract omits the supplement dose, exposure length and follow-up outcome. An isolated case without a comparison group cannot quantify risk or establish which ingredient, if any, was responsible.
What clinicians observed
The man sought care for palpitations and dizziness. An initial heart tracing showed a rapid rhythm; after adenosine was given, atrial flutter became clear. Laboratory testing, including thyroid function and electrolytes, was reported as normal.
Why the link remains provisional
The reasoning rests on the sequence of events and the reported exclusion of other causes. The abstract does not describe what happened after stopping the supplement, whether symptoms resolved or how the product was characterized.
