If this is your first time hearing about Fenfast 375, you’ll be happy to know that people have been using this product as an alternative to prescription diet pills for years. This isn’t a product that you’re just hearing about because of hype.

These pills have been used by tens of thousands of people for years.

When you take these pills, you’ll start to feel energized, which is a key component of this product. When you have more energy, you’ll feel motivated and can put an end to the fatigue that many people suffer from.

Over time, these pills are designed to provide you with several benefits:

  • Energy level increases
  • Heightened metabolic rate
  • Lower diet loss plateaus
  • Increase in general focus
  • Better appetite control

When you add in exercise or cardio, you’ll start to burn more fat and lose more calories when taking Fenfast 375. Maximum fat loss is promoted with the additional energy that is provided by Fenfast. You’ll find that you’re more focused and have the energy to really push yourself through rigorous workouts.

The key to the fat loss success of any diet pill can be found in the pill’s ingredients.

Fenfast Ingredients


Ingredients should be what everyone looks at when searching for prescription diet pill alternatives. The ingredients in Fenfast have been thoroughly tested and researched. The potent ingredients in Fenfast include:


L-Phenylalanine is the first list on the ingredient list. You’ll find this same ingredient in many high-end diet pills because it works. Highly researched, this ingredient is an amino acid that comes in three main forms.

Found in eggs, cheese, milk, fish and meat, this product is used widely in the medical industry for weight loss, depression and a variety of other medical conditions.

What this ingredient does is help to reduce hunger.

People who are overweight are often told to reduce caloric intake, but you’re left feeling hungry when restrict your calories. You may be able to curb that hunger for a day or two, but eventually, you may give in and grab an additional helping.

Once you begin eating another helping, you’ll fall off track and have a hard time getting back on track.

L-Phenylalanine provides hunger relief that allows people, especially those who are in the obese range, to start cutting back their calories and better manage their overall fat loss.

Safety is also a big consideration, and this ingredient has been found:

  • Likely safe when eaten naturally
  • Possibly safe when taken in medication form
  • Possibly safe when applied topically

Experts do not recommend using this ingredient, or any diet supplement, if you’re pregnant or nursing.


Caffeine is something everyone is familiar with because it can be found in everything from soda to coffee and even chocolate. While too much caffeine can leave you with headaches from withdrawal, the right amount of caffeine can be very beneficial for you to take.

Caffeine has been shown to:

  • Increase focus
  • Boost body temperature
  • Increase metabolism
  • Increases thermogenesis

Thermogenesis is one of the biggest benefits of Fenfast 375. What thermogenesis does is increase the body’s ability to burn fat by increasing a person’s metabolism. Energy is expended at higher rates, and people have found that thermogenesis is key for their weight loss.

Even people that have tried to lose weight for years have found that thermogenesis is what helps them lose weight.

Caffeine also acts as a natural appetite suppressant.

Combined with the other ingredients found in this prescription diet pill alternative, caffeine is a powerful additive that further boosts energy, focus and metabolism.


Caffeine Side Effects

Caffeine is a well-known ingredient and has been consumed in high volumes by people for centuries. There are always some concerns, and this goes with diet pills in general, with caffeine intake and someone with heart problems or other underlying health issues.

Scientists claim that you can safely consume 400 mg per day.

Caffeine is also likely safe when taken in larger quantities, too. If you take too much caffeine, the side effects are normally mild:

  • Headaches
  • Anxiety
  • Insomnia
  • Nausea
  • Stomach irritation

Studies also show that caffeine may be safe for pregnant women when taken in amounts less than 300 mg. Of course, if you’re pregnant, you do not want to take any diet pills or supplements.

If you do have underlying conditions, such as anxiety, bipolar and heart conditions, contact your doctor before consuming caffeine or a diet pill.

Hordenine HCI

Hordenine HCI is a powerful, proprietary formula that has been included in Fenfast, and it is an alkaloid. Studies have shown that this ingredient helps dieters that suffer from fatigue. When you’re consuming lower calories, your body has less fuel to burn and can make you feel exhausted.

Hordenine HCI has been shown to boost:

  • Energy levels
  • Mood

You’ll have a much easier time staying on top of your diet and controlling your portion size when you don’t have intense fatigue that often makes people feel sick.

Naturally found in bitter orange, this ingredient may stimulate a person’s central nervous system.

The stimulation can lead to:

  • Increase in heart rate
  • Increase in blood flow

Initially, the increase in heart rate can be scary, but this has been shown to be short-lived. Primarily used for weight loss and athletic performance, Hordenine HCI doses have some side effects that you need to know about.

Side Effects

If you take this ingredient, you have to consider that it does increase blood pressure and can also lead to heart rate increase for some people. If you have high blood pressure or suffer from heart issues, you’ll want to consult with your doctor before taking this diet pill.

Otherwise, this ingredient is generally safe and should not cause any adverse side effects for a healthy individual.



L-Theanine truly completes the Fenfast 375 formula and provides the added kick you need to get your weight under control. This ingredient is used worldwide, and you’ll be able to find ample research on the ingredient.

L-Theanine is often added because it helps alleviate:

  • Stress
  • Anxiety

And as many people on a diet already know, stress and anxiety are both part of a person’s diet. You may be going through ups and downs as you consume less food, and if you’re like me and love sweets, you may even notice a dip in your energy levels.

L-Theanine is often found in teas and in mushrooms.

Scientists claim that the ingredient provides relaxation without drowsiness, allowing you to continue your day without needing a nap.

There have also been several studies conducted on this ingredient that show it may be helpful for:

  • Increased focus
  • Better immunity
  • Improved sleep control
  • Blood pressure control

Side Effects

There are no confirmed side effects for L-Theanine. The ingredient is generally safe to take in normal quantities. The normal quantities can actually boost your health. When taking certain medications, the EGCG in L-Theanine may interact with the medication and make it less potent.

Otherwise, some consumers claim that they suffer from:

  • Nausea
  • Upset stomach
  • Irritability

What I really like is that Fenfast also offers a 30-day refund policy if you’re not satisfied with this product. The guarantee is a great addition for anyone who does experience side effects because you can return the product for your money back.

It’s peace of mind that if you’re one of the very few people with side effects after taking this product, you can request your money back.
