Probably the main concern of people with high blood pressure and taking Garcinia Cambogia extract is the adverse drug interactions that may exist.
The toxicity and side effects do not suggest any direct negative impact on blood pressure, but there is always potential for drug interaction when dealing with herbal extracts.
One double- blind, placebo controlled study of 150 obese patients showed statistically significant reductions in weight, total and LDL cholesterol, and triglycerides as well as improvement in “high density lipoprotein cholesterol.”
While some weight loss supplements tend to increase blood pressure, there is not evidence suggesting that Garcinia cambogia extract has this effect as it is not a stimulant.
However, if you are high blood pressure and are taking medications or other herbal remedies to treat it, you should consult a medical professional who can make any necessary adjustments to your dosing.
