How Does Fenfast 375 Work?

The ingredients in FenFast 375, which include caffeine, l-theanine, l-phenylalanine, and theobromine, all work together to increase your energy levels. This will allow you to exercise much more effectively, as your energy levels will rise even with a caloric deficit from dieting.

What Are The Ingredients In Fenfast 375?

In FenFast 375, you’ll find only all-natural ingredients. Below are the following components of note:

L-phenylalanine – L-phenylalanine[1] is an amino acid found in the body. This ingredient potentially helps regulate feelings of fullness by releasing a hormone called cholecystokinin. This allows you to feel fuller faster, which keeps you from overeating and helps regulate your weight.
Caffeine – Caffeine increases your metabolism, meaning you’re burning more calories faster. Caffeine has also been shown to be an appetite suppressant, which makes it easier for you to eat less.
Theobromine – Theobromine[2] is thought to both increase energy as well as suppress appetite, especially when it’s combined with caffeine. Theobromine is extracted from cacao plants and can also be found in tea leaves.
L-theanine – This substance helps reduce stress and anxiety. Stress and anxiety can make it difficult to lose weight. And although more research needs to be done, L-theanine is thought to help reduce stress levels.

What Are The Benefits Of Fenfast 375?

  • Everything in Fenfast 375 is completely natural. This means you don’t need to be concerned about any synthetic ingredients making their way into your body.
  • The ingredients in FenFast are efficient when it comes to weight loss. 
  • Fenfast 375 may help suppress your appetite while increasing your energy levels. This way, even when you’re in a caloric deficit, you’ll still have the energy you need to get in your daily exercise.
  • The L-phenylalanine ingredient might also help increase your focus. This means you’ll be able to work out longer and more effectively to help you lose weight.

What Are The Drawbacks Of Fenfast 375?

  • FenFast 375 is quite expensive. 
  • FenFast 375 contains stimulants, you might find you have difficulty sleeping while taking it.

FAQs: Consumer Questions & Answers

In our research for this report, we found that consumers are frequently asking the following questions online in regard to FenFast 375.

Overall, FenFast 375 is considered a safe supplement. However, if you are pregnant or breastfeeding, you should avoid taking this supplement.

You may also experience side effects such as dry mouth, tremors, feeling jittery, or sleeplessness because of the caffeine in FenFast 375. If you are particularly sensitive to stimulants, you may want to be cautious about using FenFast 375.

Also, note that the caffeine may cause withdrawal symptoms when you stop taking FenFast 375. You should not take FenFast 375 if you have blood pressure problems, as some of the ingredients can worsen your symptoms.

Although overall this is a safe supplement, before taking any new supplements, you should first discuss it with your doctor. This is especially true if you have any medical conditions, or are taking any other medications. Together, you and your doctor can discuss these concerns and make an informed decision.

FenFast 375 is a fairly expensive product. However, you can buy it in bulk, which will allow your supply to last longer, as well as save you some money.

The recommended dosage of FenFast 375 is 4 capsules twice a day with a glass of water 30 minutes before you eat. You should avoid taking FenFast 375 in the evenings, as the caffeine may cause sleeplessness. You should also never exceed 4 capsules a day.

Intechra Health commits customer satisfaction. If you're not happy with their products, they offer a 30-day money-back guarantee. If you purchase FenFast 375 from another retailer, they will have their separate return policy.

FenFast 375 is a safe, effective product to help you lose weight like many slimming pills. Unlike the other companies that offer a 60-day money-back guarantee, the company only offers a 30-day guarantee.

Although as with all supplements you should speak to your doctor before taking it, its all-natural ingredients are carefully selected for their quality and usefulness in weight loss.

Because of the caffeine and other stimulants in FenFast 375, you might experience jitteriness and sleeplessness. Some Fenfast 375 reviews warn new users to be cautious. Also, you should avoid taking FenFast 375 at night for this reason.

People who have issues with low or high blood pressure should avoid taking FenFast 375 as well. L-theanine can cause low blood pressure, and the ingredient hordenine, which is also found in these capsules, can cause high blood pressure.

FenFast 375 could be a good alternative to prescribed weight loss and diet pills. The all-natural ingredients in this product make it completely safe to use and are all tested for their effectiveness.

FenFast 375 won’t melt the fat off by itself, but in combination with exercise and a healthy diet, you should see results.

You should, however, speak to your doctor before taking any new supplement, especially if you are on medications or have pre-existing medical problems.

What Are Consumers Saying About Fenfast 375?

Most FenFast 375 reviews are positive. People find that this product helps them exercise more effectively, reduce cravings, and lose weight safely and effectively. However, there is a minority that says it does not work.

Trying to find an effective weight loss supplement can be an overwhelming experience. Weight loss supplements often claim to provide outlandish results. Weight loss products should be analyzed based on four key factors: potential to increase metabolism, potential to meet weight loss* goals, and quality of ingredients backed by clinical studies.

Below you'll find some of the most effective weight loss supplements on the market today, in our opinion.

Phenocal is an all-natural diet supplement that provides multiple benefits for individuals who want to lose weight quickly and safely. There are numerous brands of diet pills on the market that make all kinds of promises, but from the products we reviewed, only Phenocal did exactly what it claimed, which is to not only help consumers reach their weight loss goals easily but ensure that they keep the weight off over the long-term for an overall improvement in levels of health and fitness.



An incredible 99% of Phenocal users say they were completely satisfied with the results they achieved when taking the supplement and reported that it helped them overcome many of the obstacles that had previously stood in their way of successful weight loss, such as overeating and snacking on junk food. They also commented on the fact that while they enjoyed better energy levels which allowed them to exercise more effectively, they didn’t experience any jitteriness or feel over-stimulated in any way.

When we examined Phenocal’s maximum strength formula, we saw that it contains the most comprehensive blend of active ingredients, each one clinically proven to promote weight loss in its own powerful way, in addition to working synergistically for optimal benefits.

When you consider the scientific data that backs the efficacy of the key ingredients, it’s no surprise that it works as well as it does – for example, in clinical trials, women who took Fucoxanthin not only lost an average of 14.5 lbs in just 16 weeks but reported that the majority of the weight lost was body fat, so they enjoyed a firmer, leaner physique too!

The company who makes Phenocal, Pharmaxa Labs, offers a no-hassle 60-day money back guarantee on the product, which shows how confident they are that it will produce the results that they know their customers want to see. Indeed, the numerous user reviews shown on their website attest to the powerful benefits of this safe, doctor-developed formula and we’ve seen for ourselves just how fast and effectively it works. So, if you’re looking for a weight loss supplement that will help you finally reach and maintain your goals, in our opinion, there’s no better product than Phenocal.


Keto Blast Pro
#2 Keto Blast Pro
  • Promotes Rapid Weight Loss
  • Increases Metabolic Rate
  • Increases Energy Levels
  • Powerful Fat-Burning Properties
  • Support Appetite Control


  • Contains an all-natural blend of ingredients
  • It is said to target fat on the hips, stomach, and waist


  • It may take several months to produce results
  • Free samples are not available
  • It is a new product with limited customer reviews
  • Solid clinical data is not provided

The Bottom Line

While the diet product Keto Blast Pro may appeal to consumers for several reasons, particularly those who follow the Keto diet and prefer taking supplements in this form as opposed to pills, it is a relatively new product with limited information available. The formula is completely natural and therefore unlikely to produce any harmful side effects, but there is no solid evidence to show that it actually targets areas of fat on the body or prevents the accumulation of more fat over the long term. Additionally, it appears that this supplement may take several months to produce any noticeable results and it is not clear exactly how well it works on its own, without the benefits of regular exercise and a healthy diet plan.

#3 Razalean
  • Promotes Rapid Weight Loss
  • Increases Metabolic Rate
  • Increases Energy Levels
  • Powerful Fat-Burning Properties
  • Support Appetite Control


  • It is said to have multiple benefits
  • The formula is all natural and organic


  • Razalean is expensive
  • It has received some negative customer reviews
  • There are some reports of side effects
  • Clinical study data is not available

The Bottom Line

The diet product Razalean claims to help individuals lose weight in several ways, including increasing the metabolism and burning fat more effectively, but there is little evidence to show it works as well as the manufacturer claims it does. While Razalean contains a blend of natural, organic ingredients, including Garcinia Cambogia and Raspberry Ketones, which are relatively popular and commonly used in these types of supplements, it may not be completely safe for all individuals and there have been some reports of side effects occurring. It appears that some customers have indeed experienced some positive results from using the product, but generally, independent reviews are mixed, and this brand is more expensive than many comparable products.

Dietary supplement recommendations can be found everywhere — in commercials, through social media influencers, and from your neighbors, friends, and family. With so many different opinions, it can be hard to know which supplement is right for you. While most quality supplements undoubtedly provide health benefits, each will work in its own unique way, so it's important to determine which one will help you reach your health goals. Below you will find our subjective assessment of FenFast 375 based on the information available to us and our estimation of its overall efficacy.
