Phentaslim Review

Phentaslim is made by Optimum Nutra Inc. and has been around for less than 5 years. They are based out of Hollywood, Florida and are not accredited by the Better Business Bureau. Both women and men can use the same supplement. The claim is that Phentaslim is a powerful fat burner that can suppress appetite, boost
energy levels and elevate mood without the jitters.* When looking to contact their customer support line to ask a few more questions, there was obviously no number available. They give you a form to look at on their website to contact them here. Their return policy is as such: “If, for any reason, you are not 100% satisfied, please return it within 60 days. We will refund the purchase price minus a handling fee of $10 (USD) . The original shipping and handling fees are non-refundable. We'll pay the return shipping cost if the return is a result of our error.”

The Ingredients In The Phentaslim Diet Pill: Green Tea (375mg), Caffeine (270mg), L-Theanine (225mg), L-Carnitine (200mg), L-Tyrosine (200mg), Panax Ginseng (120mg), Guarana Seed (100mg), Magnesium (80mg), Cayenne Pepper (50mg), Niacin (Nicotonic Acid) (20mg), Zinc (As Zinc Acetate) (15mg), Black Pepper Extract (6mg), Vitamin B6 (As Pyridoxine HCL) (1.8mg), Riboflavin (Vitamin B2) (1.7mg), Thiamin (Vitamin B1) (1.3mg), Vitamin B12 (As Cyanocobalamin) (10mcg), Gelatin and magnesium stearate.

Do Dieters Lose Weight On The Phentaslim Diet

We were not able to find many positive reviews other than the ones Phentaslim has on their website which of course are posted to encouraged sales. They were few and far between, as Amazon won't even sell this supplement (never a good thing) and so the reviews are rather scattered but we found one worth noting. The overall consensus from many of the reviews was the amount of caffeine present in the pills making them hard to take long term, especially for those sensitive to caffeine. Many times, companies such as Phentaslim will pay an arm and a leg to have their product advertised on a popular network to boost sales, and it doesn't always mean it is a good product.

“Although Amazon doesn't sell Phentaslim, I couldn't find anywhere else to post my review. So, I tried this for about 25 days before stopping. I have lost weight, but not because of these pills. I've been eating less, and the weight is dropping about a pound a week. I would not buy this again. In fact, I would not buy another weight loss pill until Dr. Oz is resting on Mars.” Getterdun*

Is The Phentaslim Diet Easy To Follow?

It is recommended that the Phentaslim pill would be taken with water, 20 minutes before meals, 3 times daily. It is recommended to take Phentaslim no later than 6 pm because it does contain ingredients with caffeine (Green tea, Caffeine Anhydrous, Caynenne pepper) that can keep you up at night or make it hard to sleep. Other than that, this is not a diet program, or diet plan that needs to be followed in order to maintain and obtain a healthier lifestyle. This is just a diet pill that has has poor results from customers who have put their faith in it to try it. Side effects have been stomach issues, headaches, jitters, and excessive thirst. For one bottle you will pay roughly $60.00 plus shipping which is not cheap when it is all said and done. There are more caffeinated stimulants in the pills to make someone bounce off the walls, so be mindful when you are taking these!

There is no big explanation on their website as to why scientifically their formula works for long term weight loss, and they do a better job avoiding questions rather than just answering them. For example, when asked if their diet pills had side effects they answered: “Because Phentaslim is produced in a GMP certified facility you can be assured it is of the highest quality. The individual ingredients are the best you can buy and are all 100% natural and approved for use by the FDA.”


We are not too happy about the fact that they only have 30-day money back guarantee with £10 handling charge but we do like that ingredients are displayed on their home page and has specifies the amount of each ingredient. Phentaslim only has 6 vitamins and minerals, a very high dose of caffeine (which can create jittery feeling), and a few hyped ingredients that have no science to back them up. Their social media and support networks don't exist which means the company does not truly want to help you lose weight. They are more concerned with getting more fake testimonials put on their site, as well as a new credit card to store on file. For people seeking long term sustainable weight loss we highly recommend looking into nutritious meal plans that provide guidance and active customer support.*
