How Does Phenastin Work?

The ingredients in Phenastin speed up the metabolism, which greatly improves the fat-burning process of thermogenesis. This faster and more efficient fat burning leads to steady weight loss. Research shows that stimulating thermogenesis can lead to significant weight loss.

In addition, the supplement makes the process of glucose uptake more efficient, and this effectively curbs your appetite, so you consume less calories. Modulating glucose levels does decrease hunger, according to studies.

Phenastin Ingredients

Phenastin speeds up your metabolism. It initiates the fat-burning process of thermogenesis, which leads to weight loss. The product also curbs hunger, so you don’t overeat.

Some of the primary active ingredients are:

Alpha Yohimbine

– This is a nerve-blocker which has been associated with some potentially serious side effects like high blood pressure, heart disease, kidney, thyroid, liver disease or seizure. A 2006 study looked at the weight-loss effects of Yohimbine on star athletes, and found it to be effective for this purpose.

Caffeine Anhydrous

– This substance, commonly found in coffee and chocolate, speeds up the metabolism and so accelerates the process of fat burning. It also provides you with an abundance of additional energy. The Mayo clinic has stated that the amount of weight you can lose from consuming caffeine is limited.

Peppermint Extract

– This is a plant which is native to both Europe and North America. It has numerous medicinal properties, including benefits to the skin and soothing the gastrointestinal system. Peppermint oil has also been used for weight loss.


– This is derived from the seeds of an African plant called Griffonia simplicifolia. It’s used for a number of conditions like depression, anxiety, and obesity. 5-HTP is a known mood enhancer. There’s some research to indicate that 5 HTP can help with weight loss.

    Phenastin Works for me.
    I decided to try Phenastin when I put on 10 lbs during the Pandemic. Working from home, snacking more and less time outside the house really affected my weight, energy, and digestion. Since I started taking it over 2 months ago, I’ve had more energy for exercise and regular bowel movements.
