Is Garcinia Cambogia safe – what are the side effects?
A look at the potential side effects, and who should and should not take this supplement.
The literature reporting on clinical trials conducted on Garcinia Cambogia concludes that the product is safe for most people and is a well tolerated supplement.
The best advice on dosage is to take between 500mg to 1000mg before meals and not to exceed 3,000mg in a day.
Fortunately, most garcinia supplements only contain a 1000mg daily serving so should not pose any problems when dosage instructions are followed accordingly.
How long should it be used for?
Because all clinical trials so far have been carried out over a short-term, the sensible course is to take Garcinia Cambogia for no longer than three months.
Are there any potential side effects?
A number of relatively mild side effects have been reported by some users of Garcinia extract. These have included headaches, insomnia, dizziness, diarrhoea and flatulence.
Most of the clinical trials report no difference in occurrence of side effects between participants taking the supplement and those given merely a placebo, so it is possible that those reported by a small number of users are unrelated to the product or may perhaps be ascribed to excessive dosage.
There have been some reports of a more serious problem which has, perhaps unfairly, been attributed to Garcinia Cambogia: that it may cause liver damage (hepatotoxicity), though it must be stressed that this has not been confirmed in any of the clinical trials so far conducted.
Many supplements incorporate additional ingredients, and it may be that something other than Garcinia extract proves to be the culprit. In the meantime there is no scientific link between Garcinia Cambogia and liver damage. In the interests of safety, users must not exceed the recommended daily dose.
Finally, a number of studies with animals demonstrated that Garcinia Cambogia may cause testicular toxicity. A study reported in the Journal of Phsiology and Behaviour in 2008 concluded, however, that use of Garcinia extract does not affect levels of sex hormones in humans.
It is recommended that potential users of Garcinia Cambogia ensure that the product they purchase contains 50-60% HCA (with potassium) and that there are no artificial compounds listed in the ingredients. The advised dose of 1000mg each day must not be exceeded and ideally the supplement should be taken for no longer than 12 weeks.
We recently examined the weight loss claims of Garcinia and recommended two supplements which have good user feedback and a high 60% concentration of HCA.
