What is Hoodia Gordonii?

Hoodia Gordonii is a small plant that is used in famine to suppress appetite and thirst. This plant is a source of a large amount steroidal glycosides and this seems to be the only active ingredient that suppresses appetite and thirst. There is very limited studies that prove the effectiveness of Hoodia Gordonii. Let’s take a look. (Frank, 2019).

Hoodia Gordonii clinical trials

A study conducted by Unilever Research & Development (2011) assessed the effects of Hoodia on weight loss and appetite. There were 49 overweight and obese women who were supplemented 1.110mg of Hoodia twice a day an hour before a meal. After 15 days, the study reported a reduction in appetite by 24% compared to placebo group. However, the appetite of the placebo group also reduced by 18%. Evidently, Hoodia may slightly decrease your appetite but not by a significant amount. However, an increase in blood pressure and pulse rate were reported.

This study proves the insignificant effect that this supplement has on appetite. Due to its hype,  you may not yet be convinced of its poor efficacy. So here is another study for you.

Unilever Research & Development (2016) looked into the effects of Hoodia again, and there were 60 slightly overweight women involved. In comparison to the previous study, more participants were involved which suggests a more reliable source of information. The bigger the pool of people, the better.

Along with the previous study, the results were disappointing. No significant changes in appetite or body weight were reported. Therefore, despite manufacturers and sellers marketing this supplement as fat burning, clinical trials demonstrate lack of efficacy.

Our thoughts

Hoodia has been on the market for a very long time, and some products may contain great reviews. Nonetheless, it’s important to understand that although Hoodia may be ineffective on it’s own, it may be a great ingredient combined with other fat burner ingredients like the green coffee extract. Definitely more studies are required to establish if Hoodia is effective or not.

Who should avoid Hoodia Gordonii?

People with certain conditions should avoid it:

  • Diabetes
  • High blood pressure
  • Blood disorder eg: blood clotting
  • Eating disorders eg: anorexia or bulimia

There are very limited studies of how Hoodia can affect people with these conditions. However, it may be due to the medication that a person takes to minimize the symptoms of these conditions.  You should contact your doctor or GP before taking any fat burning supplements. In particular, if you have any medical conditions or using any medications.

How much Hoodia Gordonii should I take?

Before taking this supplement, it may be worth contacting a pharmacist or a doctor. There is no sufficient evidence that concludes a safe dosage.


So, taking both studies into account, we can safely conclude that this supplement fails to deliver on the market promises. However, as more studies surface this article will be updated accordingly.
