Phenastin is an organic weight-loss supplement. Phenastin includes ingredients that may aid in weight loss by increasing how much energy the body uses on a daily basis.
This product starts working very quickly, according to reviews on amazon as well as the supplement’s website (amazon.com, phenastin.com). Phenastin also contains ingredients that may act as an appetite suppressant, helping you to avoid overeating.
Phenastin Ingredients – What to Look For
There are 6 active ingredients in this product, which may help speed up metabolism and initiate the fat-burning process of thermogenesis.
The following are three of the key ingredients –
- MenthaPiperita – This is a common peppermint extract native to Europe and North America. More research is needed on the benefits of this supplement for weight loss, although research has shown it may be effective in suppressing the appetite. It can also be helpful in reducing gastric motility (how quickly and how often our digestive system works), which is helpful for those with irritable bowel disease.
- Yohimbine – This is a nerve-blocking agent that has been used for both weight loss and for the treatment of erectile dysfunction. Yohimbine acts to increase blood flow and improve circulation throughout the body. This substance is associated with some potentially serious side effects such as an increase in blood pressure, kidney disease, heart problems, seizures, or liver disease. Studies have found this to be an effective fat-loss agent, but there needs to be more research on its weight-loss implications.
- Caffeine Anhydrous – This substance provides users with an increase in energy as well as increased thermogenesis. It ultimately aids in weight loss, but is shown to be more effective when combined with other ingredients. According to the Mayo Clinic, the amount of weight you can lose by consuming caffeine alone is limited. Therefore, the combination of caffeine with the other ingredients in Phenastin makes its potential for weight loss greater.
How Does It Work | The Science Behind Phenastin
The ingredients in this supplement initiate the process of thermogenesis, which leads to fat burning and consistent weight loss.
Studies have indicated that being in thermogenesis can cause weight loss by increasing how much energy subjects burn during their usual daily activities. The peppermint extract may also aid in hunger as mentioned above, suppressing the appetite.
A secondary process of this supplement is to help tightly control glucose levels, which leads to decreased hunger and fewer calories consumed overall. Research does show the weight-loss effects of modulating levels of glucose.

Is There Anything Else You Should Know About Phenastin?
Taking a weight loss supplement may aid in your weight loss goals. However, this supplement should be your secondary method of weight loss. Always ensure that you are practicing healthy habits and living a healthy lifestyle:
- Follow a healthy and balanced diet, making half of your plate fruits and vegetables. Ensure you are eating enough protein daily as well as fiber-rich whole grains (aim for each of these to take up 1/4th of your plate).
- Remember to exercise on a regular basis! The Department of Health and Human Services recommends that adults get at least 5 to 5 hours of moderate-intensity activity, or 1.25 to 2.5 hours of vigorous-intensity aerobic physical activity on a weekly basis.They also recommend spreading activity throughout the week for optimal results. Additional health benefits are added when individuals exceed 5 hours of weekly activity.
- Remember to be patient with your weight-loss journey. Quick results are not sustainable or long-lasting. As long as you are going in the right direction, that is what matters!
