Phenternin’s formula contains Hoodia gordonii as its single active ingredient. According to the FAQ on the official Phenternin product page, every bottle contains a “whopping 90 count bottle with 750mg of Certified 100% Pure South African Hoodia per pill and a 2,250 daily dose of pure Hoodia.”
Hoodia gordonii is said to be the only hooida that actually causes appetite suppression because it is native to a cactus located in a specific region of South Africa that was used by the indigenous people of South Africa as a natural appetite suppressant. While other products claim to contain this pure hoodia, when you buy Phenternin Hoodia, it apparently is accompanied by a USDA protected plant permit, South African Government Certificate of Authenticity, CITES certificate and Phytosanitary permit.
While Phenternin may indeed contain the best hoodia the OTC weight loss market has to offer, the problem is that while some studies have found that hoodia has the potential to cause appetite suppression, there isn’t enough conclusive scientific evidence to suggest that it does work. The reason why it is believed it causes appetite suppression is hoodia contains a chemical called P57, which is believed to decrease feelings of hunger. However, it is not known if hoodia causes this effect in people.
As for potential side effects, preliminary research has indicted that hoodia may be dangerous to the liver, could cause gastrointestinal distress, elevate blood pressure, and may interact with certain medications. However, whether hoodia can actually cause these side effects is unknown. Just as positive claims cannot be proven about this substance, neither can negative ones. The point is that hoodia simply has not been researched enough for scientists to know exactly what it can and cannot do. Thus, whether or not it is effective for aiding in weight loss is unknown.
However, one bonus of Phenternin is that it is stimulant-free, which means that the risk of unwanted stimulant-related side effects that is common among OTC weight loss products, such as insomnia, jitters, anxiety, etc., is not present.
While Phenternin does seem to be a legitimate hoodia product and possibly worth trying for those who are interested, you should first consult with your doctor, especially if you have an existing medical condition or are taking other supplements or medications.
