Phentaslim Review

Metabolism enhancement leading to faster calorie burning is a major intended weight loss benefit, as well as appetite suppression. They specially mention that reliable weight loss results are determined by the focus and attention paid to by consumers, meaning diet and exercise are probably likely.

A single bottle for 30 days’ worth of use is offered at $69. They claim this can support weight loss from 3 to 10 pounds. No proof is provided to help support this claim, but they do mention that this is not a certifiable fact, only a possible benefit.

As a daily cost this amounts to $2.30. You can review the most effective and high value weight loss supplements by clicking here.

No supplements facts list is provided but they do specify the dosage strength for each ingredient:

Caffeine Anhydrous: Stimulant ingredient that is dehydrated and used for its fast acting energy and metabolism boosting effects. In Phentaslim there’s a grand total of 270 mg per serving, which is almost equal to the same caffeine in 2 cups of coffee. This is a lot which is why the company makes it clear that this should not be used beyond the 3 capsule a day limit.

Though this can have positive weight loss effects, it’s a cheap additive which can potentially cause tolerance problems as well as side effects.

Panax Ginseng: Plant extract intended to prevent fatigue, improve immune function, and support stamina. It’s also used to prevent a loss of appetite, but it’s unknown if this would have any effect on weight gain.

Guarana Seed: Stimulant rich seed which is often found in Brazil. It’s a natural source of both theobromine and caffeine, which can affect energy, metabolism, and focus. Overuse of this can potentially cause many side effects commonly seen in stimulants.

Green Tea: A tea which is rich in antioxidants and which acts as a metabolism booster. There are a total of 4:1 ratio, making it concentrated and more rich in the active chemicals which can potentially deliver more benefits.

Acetyl-L-Carnitine: Important amino acid which plays major roles in the body, including metabolism and quicker recovery from exercise.

Cayenne Pepper: Metabolism boosting spicy pepper which also has an effect on blood flow. The active ingredient is known as capsaicin, and it also provides spice. The way this is processed limits the potential for any spiciness.

Brands which affect weight loss without the use of stimulants are highlighted in our top 10 list.

Stimulants

The heavy use of stimulants limits this brands potential since it’s possible it may lead to tolerance. Over time the body will likely greatly reduce the positive effects from caffeine. This often requires what’s known as cycling, meaning it has to be taken off and on.

Stimulants furthermore put user’s health at risk, as there’s a potential for all kinds of symptoms. It’s not unlikely for excess use to cause headaches, rapid heart rate, anxiety, jitters, and general unease.

In the “Customer Opinions” section we go more into detail about the potential side effects caused by these stimulants.

Business

Their official company name is Optimum Nutra Inc. Information about them is limited, but they do have operations in Panama.

Their returns process is clear; they back each bottle with a 60 day guarantee as long as users pay an additional $10. This is only offered on a single opened bottle however and any additional bottles must be unused.

There is concern that a supplement review site called Watchdog.com has some sort of affiliation with this brand, since they highly tout it and the website design is oddly similar. We don’t know for certain if they are linked together, but it does seem possible.

Consumer Opinions

Reviews on this brand are limited and there isn’t many detailed descriptions given about it.

The few reviews we could find had negative things to say. Because there weren’t many experiences mentioned however, we can’t say for certain what is likely. The few reviews found were all negative as they experienced side effects.

Many typical symptoms were mentioned which common to heavy stimulants are such as jitters, sickness, and even uncontrollable shaking. Increased urination was also a problem which is rarer, but also sometimes seen in stimulants.

The most favorited customer approved weight loss brands are all singled out in our top 10 list.

Conclusion:

Phentaslim is no doubt rich in a lot of useful ingredients even though many of them are naturally found in common foods.

They use additives like nutrients and amino acids which are fairly common, and unfortunately cheapen it with unnecessary caffeine. The high amount of caffeine may potentially cause symptoms, and it’s unclear if this is actually going to lead to long-term benefits.
