Phentaslim Reviews - What Is It?

WARNING: DO NOT BUY Phentaslim Until You Read This Review!
Is it a Scam? Does It Really Work? Check Ingredients, Side Effects and More! Emily Butler

Phentaslim is a new fat burner that has its own official website according to which it has helped more than 40,000 people all over the world by lowering their cravings, boosting energy and providing more intensive exercising. It is claimed to be natural and clinically proven but we are going to learn whether these claims are true by looking at the main ingredients, side effects, clinical studies and customers' reviews of this product. I managed to do an intensive research and found hundreds of dieter experiences on the Internet. For this research I managed to compress all the information necessary to understand whether Phentaslim is worth your attention and whether it can bring desired effects.

This weight-loss product is manufactured by Optimum Nutra Inc. and contains a big list of ingredients which we are going to discuss a little bit later. The information about the constituents is very scarce and there is not a word about possible side effects they may have on the human body. This supplement can be used by both men and women and it helps to decrease hunger, boost energy, reduce excess body fat and relieve food cravings. On the official website it is mentioned that the manufacturer offers a money-back guarantee.

Ingredients of Phentaslim - Does It Really Work? Is It a Scam?

Even though Phentaslim contains a lot of ingredients their amounts are not mentioned on the official website. The capsules are said to contain natural ingredients, namely caffeine anhydrous, guarana seed, green tea extract, zinc acetate, magnesium, cayenne pepper, L-tyrosine, L-theanine, panax ginseng root, and L-carnitine. Green Tea is the first ingredient in the product that is claimed to be beneficial for the human metabolism and thermogenesis, however its actions is so light that it can be hardly noticed.


Caffeine is a very disputable ingredient as despite its ability to boost metabolism, curb hunger and increase energy levels it also can cause such unpleasant side effects as jitters. This component should be avoided by people with heart diseases and hypertension. L-Theanine is a non-essential amino acid that can improve attention and cognition as well as reduce stress but in a very mild way. Its effect is unnoticed without caffeine.

L-Carnitine is also an amino acid that helps the muscles to recover from workouts and improve fat metabolism, however, in some users this component causes heart problems. L-Tyrosine claims to help with weight loss, suppress appetite but only when taken in combination with certain B vitamins. Panax Ginseng is said to boost energy levels and improve the overall well-being but only when used in high dosages. Besides, this ingredient may have potential side effects, so be careful with this substance.

Guarana Seed is a fruit extract that contains a lot of caffeine that is why it can be harmful for people with certain health conditions. Magnesium helps to stabilize the nervous system and improve the work of muscles, however, before starting its usage check your Magnesium levels to avoid overdosage. Cayenne Pepper is said to raise the core temperature of the body to boost metabolism but it has to be taken with certain concern. Niacin is claimed to improve heart health and lower cholesterol levels. Still, it is unknown what amount of this element is used in the product.

Zinc sustains energy levels while Black Pepper Extract is said to improve absorption of other constituents. Other ingredients in Phentaslim include Vitamin B6, Riboflavin (Vitamin B2), Thiamin (Vitamin B1), and Vitamin B12 all of which can work only in high concentrations. The list of ingredients in the supplement is impressive. I would recommend decreasing their number to ease users' worries about side effects. It is also necessary to do enough medical research to ensure that these components work together in a positive way.

Customer Reviews - Does It Have Any Side Effects?

The manufacturer keeps silent about the adverse reactions which may happen due to the usage of Phentaslim. It means that they do not care much about their customers but I have made a thorough research of all the data on the product's side effects given on the Internet. In one word, this supplement is not able to solve the problem of extra weight on its own. You will need to exercise regularly and to stick to the low-calorie diet.

Phentaslim has an unproven formula that includes panax ginseng root and cayenne pepper. Neither of these components has been proven to influence body weight or fat content. This is really concerning. After doing the research, we can conclude that the individual aspect of these pills is quite troublesome as there are too many fad ingredients, negative reviews and serious side effects. This supplement does result in a lot of disappointing claims. Although the official website claims that Phentaslim contains only those ingredients that have been backed by clinical research, we failed to find any actual studies conducted by the company. There is no documentation proving these claims.

On the website it is said that the product contains only natural ingredients but they are present in extremely low amounts so you can hardly feel any difference. However, there is a caution: pregnant and breastfeeding mothers, as well as young people under 18 years of age should avoid using this product. If you are taking any medications on a regular basis or have any medical conditions you are recommended to consult your doctor before starting to use the supplement. You can find a lot of Phentaslim reviews from customers online. Most of them are negative. Here are some of them.

"There are no accurate descriptions of the ingredients in Phentaslim that is why I was afraid to start taking it but I risked. Unfortunately, my expectations were justified as the product failed to help me lose any weight."

"Phentaslim does not work on its own, only with a strict diet and exercise. What is the sense of using it then? To my mind, it is waste of money. Besides, I suffered from nausea all the time. I do not recommend this product to anyone."

"Not effective at all. Another scam pill. Been taking it for six weeks now. When I tried to get mu money back they said that I addressed them too late, but they did not inform me of the term in during which the money-back service works."

Where To Buy Phentaslim?

Phentaslim is available from its official website only. It costs $60 per bottle. Two bottles can be purchased at the price of $100, while you get three bottles for $140. It is available on Walmart, Amazon or GNC.

My Final Summary

Phentaslim capsules do not prove to be effective in the process of weight loss. The official website offers only two customer testimonials which seem to be completely fake. Not to mention, the product is associated with side effects. The users of this supplement claim they noticed a big need to urinate frequently even during the night. It means that Phentaslim works to remove liquid from your body but not fat. Some people felt terrible nausea.

Among positive things about Phentaslim there is free shipping to the UK if you order more than two bottles of the product. They also offer a 30-day satisfaction guarantee. We are not comfortable to recommend this formula. If you really want to lose fat, we advise you to choose a supplement that has many positive customer reviews, is not too expensive and does not rely on fad ingredients.

Affordable Alternative

Many modern doctors are sure that the most effectively the problem of excessive weight can be solved with the products increasing human metabolism and burning fat and calories. Luckily, there is such a product on the market. It is known as PhenQ. They are completely natural and effective. I recommend you reading my review about PhenQ. I believe your life will be changed with this product!
