Side Effects of Hydroxycitric Acid

Little information is available on hydroxycitric acid side effects, because only a few small studies have been done. Known side effects include stomach pain, headaches, and nausea. Signs of an allergic reaction are also possible, such as a rash, unexplained swelling, or difficulty breathing. If you experience any possible side effects of hydroxycitric acid, let your healthcare provider know so that treatment (if necessary) can be obtained.

Does Hydroxycitric Acid Cause Side Effects?

As with any medication or supplement, side effects are possible with hydroxycitric acid (HCA). However, as with most supplements, very little information is available about side effects of hydroxycitric acid, since large, adequately designed clinical studies have not been performed. Large studies are important in order to find any rare side effects, since small studies are not good at finding these.

Possible Side Effects of Hydroxycitric Acid

Only a few possible side effects of hydroxycitric acid have been reported, including:
  • Nausea
  • Intestinal or stomach pain or discomfort
  • Headaches.
It is important to understand that only a few side effects have been reported because only a few, relatively small studies have been done.
As with any other medication or supplement, be sure to watch for signs of an allergic reaction, such as:
  • Rash
  • Hives
  • Itching
  • Swelling of the mouth or throat
  • Wheezing
  • Difficulty breathing.
In studies in rats, high doses of hydroxycitric acid caused testicular shrinkage and damage, although it is not known if this is also true for humans.

Final Thoughts on Side Effects of Hydroxycitric Acid

You may experience some or none of the side effects of hydroxycitric acid listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried. Therefore, make sure to let your healthcare provider know if you develop any side effects while taking the supplement. You should also let your healthcare provider know if you develop something that "just does not seem right" during treatment. While it may not be a side effect of hydroxycitric acid, your healthcare provider will be able to diagnose and treat the problem.
