FENFAST 375 Ingredients

The FENFAST 375 ingredients have each been carefully tested and researched to provide a product that is powerfully beneficial but also safe enough for long term use. Intechra Health's team of scientists who engineered this formulation meticulously chose EVERY ingredient for their general safety and clinically researched benefits that can support healthy weight management.

FENFAST ingredients were then combined in the ideal quantities to promote a healthier weight through enhanced energy levels and improved mental acuity, so you can stay focused on reaching your goals.

Although the formulation of FENFAST 375 contains only a few ingredients, their synergistic abilities have been shown to amplify the effects. FENFAST 375 white & blue speck tablets contain:



The first on the list of the ingredients that comprise the FENFAST formulation is L-Phenylalanine. This substance is sometimes seen in the highest quality diet pills because of the many benefits that it has been shown to offer dieters. When taken in the appropriate amount, this ingredient can be very helpful.

L-Phenylalanine is an amino acid that is used for a number of purposes by the human body. Scientists have been very curious about the various advantages that this substance has to offer and the different applications that it can have, such as in the area of weight loss. For this reason, it has been clinically studied for several years to make sure that its impact on the body is well understood. It has been shown to offer numerous beneficial effects.

A great deal of the research* that has been performed on L-Phenylalanine, particularly in recent years, has been directed toward the impact that it can have on weight management.

Discover the way in which this ingredient produces this effect:

  1. It is used by the body to make chemical messengers responsible for energy regulation and intake.
    This is especially important for dieters, as certain chemical messengers, such as dopamine, have been shown to enhance concentration and motivation.
  2. By helping to boost the body’s energy levels, you can burn through more calories every day through exercise.


Next among the FENFAST ingredients is caffeine. This is a well known and highly studied synthesized stimulant which is commonly known for its ability to build the metabolic rate. When the metabolism achieves a higher performance, it means that the body is better able to burn through calories and fats, which can make weight loss easier for a dieter – particularly when combined with proper eating and exercise.

True Fact About Caffeine
Research has indicated that by using caffeine regularly, and in the right doses, obese patients were able to decrease their levels of body fat*.

The way that this first among the FENFAST ingredients works is through a thermogenic process. This occurs when the body temperature is increased, causing energy (in the form of calories and fat) to be expended as heat. Studies have indicated that the heavier a person is, the greater the effect of thermogenesis on the body.

Among the FENFAST ingredients, caffeine may also function as an appetite suppressant. This is very handy for assisting in eating a smaller amount of food, which can help to promote weight management. The formula functions very well in conjunction with a reduced calorie diet plan.

"Relationship between basal metabolic rate, thermogenic response to caffeine, and body weight loss following combined low calorie and exercise treatment in obese women". [1994, 18(5):345-350];jsessionid=sW4cu3KeAHFe2vCui3nt.4


The next ingredient in the powerful FENFAST formulation is Theobromine. This proprietary formula is enhanced in a particularly important way through the inclusion of this ingredient and its combination with caffeine.

Theobromine is an alkaloid extracted from the cacao plant, which is the same source used for producing chocolate. It is also found in other natural food sources such as in tea leaves.

Theobromine is included in FENFAST 375’s weight loss support formula due to the clinical research conducted on it. For example, one study*** that examined theobromine showed that when using this ingredient in the form of a supplement, it can help to boost energy levels and may also suppress the appetite, as has been shown in certain caffeine studies. At the same time, it indicated that when compared to using a placebo, combining theobromine with caffeine can help to enhance its stimulant effects.

Finally, the FENFAST 375 formula would not be complete or nearly as effective without the addition of L-Theanine. Clinically researched and used worldwide, L-Theanine has been shown to be helpful for reducing stress and anxiety****. An effective ingredient that helps people to feel more relaxed while dieting is important.

L-Theanine can help people overcome anxiety and stress due to dieting and making changes to their eating habits. It may be particularly helpful for people who are struggling with food addiction.
