Phentaslim Reviews

phentaslim

“Imagine how soon the weight will be dropping off!”

Phentaslim is receiving high marks from diet pill review sites and consumers alike.

Supposedly this “cutting edge” formula will help you lose weight quickly, safely, and effectively.

“It’s as easy as 1-2-3!” say advertisers at Phentaslim.com. “Phentaslim only uses ingredients that have been proven using proper research, to be safe and effective in promoting weight loss.”

But is Phentaslim as great as it looks?

I have my doubts, so I did a little research into the formula to find out the truth. . .

Are Phentaslim Ingredients Effective?

For a formula that supposedly contains the “highest quality ingredients from around the world,” I’m not exactly amazed by Phentaslim’s formula.

The ingredients are popular, easy to buy, and common to countless diet pills on the market. What sets Phentaslim apart from other supplements are the ingredient concentrations. Unlike other supplements, Phentaslim doesn’t hide behind a proprietary blend, so you know precisely what you’re getting with every serving.

Furthermore, Phentaslim.com provides additional clinical research to back each ingredient used (though there are no peer-reviewed clinical studies on Phentaslim itself).

In case you are unfamiliar with Phentaslim, here’s a quick breakdown:

Guarana Seed. Clinical studies show guarana effectively improves energy levels and mood.

However, studies also show guarana extracts are more effective when taken in 37-75 mg doses rather than 150-300 mg. [1]
Phentaslim contains 100 mg per serving, which is enough to increase energy levels but might not be as effective for enhancing mood.

Caffeine Anhydrous. Caffeine increases alertness, reduces fatigue, and accelerates caloric expenditure. Although caffeine does not improve maximal oxygen capacity, it could temporarily enable an athlete to train at greater power output and/or train longer. [2]

Studies show caffeine with green tea stimulates thermogenesis and fat oxidation, significantly reducing body weight, fat mass, and waist circumference. [3]

Green Tea Extract. Green tea contains approximately 3-5% caffeine, which makes it an effective energy booster. However, its real weight loss potential lies in its high catechins, flavonoid, and polyphenol concentrations.

Studies show the continuous ingestion of green tea extract rich in catechins leads to a significant reduction in body fat, systolic blood pressure, and LDL cholesterol. [4]

Cayenne. Cayenne contains capsaicin, a spicy thermogenic which increases the body’s core temperature for enhanced fat burning.

Experts believe red cayenne pepper may help burn calories and curb appetite in individuals who are not used to eating the ingredient[5] . Animal studies suggest capsaicin may effectively stimulate lipid metabolism in adipose tissue. [6]

Raspberry Ketone. Raspberry ketone affects adiponectin levels, which regulates appetite.

Animal studies suggest raspberry ketone significantly increases norepinephrine-induced lipolysis as well[7]. But further human trials need be conducted.

L-Tyrosine. Tyrosine is a nutrient precursor to dopamine, norepinephrine, and epinephrine.

According to Dr. Mauro Di Pasquale, “tyrosine improves some of the neurobiological disturbances of dietary restrictions without causing an increase in body weight.”[8][9]

While promising, the research behind tyrosine for weight loss is inconclusive. The study was conducted on mice, not humans. Though it didn’t result in weight gain, tyrosine supplementation didn’t trigger weight loss either.

L-Carnitine. Carnitine acts as a transporter for fats and fatty acids. It carries them to the cell where they are then converted into energy.

Yet despite the ingredient being marketed for weight loss, clinical studies show it has no effect on total body mass or fat mass. [10]
5-HTP. 5 HTP is converted into serotonin in the brain. Serotoinin regulates numerous functions such as metabolism, sleep, cardiovascular functions, and appetite – all contributing to weight gain (or weight loss).

According to one study, 5-HTP may have a mild appetite suppressing affect. Participants who supplemented with HTP lost approximately 2% of their body weight. [11]

However, the study featured nearly 900 mg HTP, while Phentaslim only contains 100 mg.

Panax Ginseng. Panax weight loss studies are fairly mixed.

According to the American Diabetes Association, Panax ginseng contains a constituent known as ginsenoside, which is associated with a significant reduction in food intake and an increase in energy expenditure and body temperature. [12]

On the other hand, the study was conducted on mice, not humans. According to American Academy of Family Physicians, Panax ginseng is no better than a placebo when it comes to promoting weight loss.[13]

Phentaslim also contains multiple vitamins, minerals, and antioxidants for improving your overall health and wellbeing. Though they don’t have a direct impact on weight loss, these vitamins and minerals may contribute to a faster metabolism.

Safety Concerns and Side Effects

Currently there are too few consumer reviews to analyze Phentaslim’s full range of negative side effects.

Typically speaking, however, the stimulating ingredients in Phentaslim have the potential to cause the following:

• Dizziness and headaches
• Nausea and stomach upset
• Irritability and mood swings
• Restlessness and insomnia
• Rapid or irregular heartbeat

Consult your doctor if you are currently taking any medication.

Phentaslim should not be taken by anyone under 18, by pregnant or breastfeeding women, or individuals with a BMI of less than 18.5.

Is It Easy to Use?

Yes. Phentaslim is easy to use. Take 1 capsule in the morning, 20 minutes before breakfast, and a second before lunch. Each serving should be accompanied with water.

Do not exceed 2 capsules daily. Increasing the dosage will not increase your results.

Can Women Use Phentaslim?
Yes. Women can use Phentaslim. There are no ingredients specifically for men or women.

Can Vegetarians Use Phentaslim?
Phentaslim contains small amounts of gelatin the capsule gel.

Where to Buy Phentaslim

Return Policies

Phentaslim is backed with a 30 day guarantee, so if you don’t like your results, you can return it for a full refund.

However, read the fine print before you whip out your credit card. . .

Products must be returned with an RMA number (which can be obtained from customer service) and it may take up to 2-3 weeks before the refund will be issued.

Shipping and handling fees are non-refundable, and according to the Terms and Conditions page, “you return only one unused bottle and any remaining bottles unopened in resalable condition.”

One unused bottle? I’d like to think that this is a typo on their page and not the actual policy. Otherwise, if you’re tried it, you’re stuck with it.

Additionally, “you agree that a small handling fee of $10 will be deducted from the refund price to cover administration charges and distribution costs.”
So much for a 100% guarantee. . .

More About the Manufacturers

For a product receiving such high praise, I’m surprised information is limited on this product. Aside from a few diet pill review sites and Phentaslim.com, I can’t find Phentaslim or Optimum Nutra Inc. anywhere online.

No press releases. No rip-off reports. No celebrity endorsements.

This can be both a good and bad thing.

Phentaslim does not come with a long list of negative reviews, a mile-long complaint list with the BBB, or hyped up testimonials on ridiculous TV advertisements.

Since there’s nothing outrageously “bad” about the product, then it must be doing something right, right?

Then again, there isn’t any positive information either . . . no doctor recommendations. No clinical studies specifically on Phentaslim (rather than just the separate ingredients). The consumer reviews are limited to a few positive remarks left on DietPillsWatchDog.com. Even these come with a suspiciously positive review for a product with no company information.

The only solid information I have on Optimum Nutra Inc. is a return address located in Atlanta Georgia, which happens to be a fulfillment center for various companies. It basically acts as a drop-off point for consumers to mail in their unwanted products.

Despite claims to make Phentaslim in a GMP certified facility, there is no solid proof Optimum Nutra Inc. is wholly reliable.

I’m willing to lean either direction here, but until I learn more about Optimum Nutra Inc., I’ll remain skeptical of their top-selling fat burner.

Pick It or Pitch It?

Phentaslim has some great ingredients for promoting weight loss, and I can tell the manufacturers did their research when they made the formula.

However, the product is still too new and not enough information is available about the manufacturers for me to feel comfortable recommending it.

I’d love to know more about Phentaslim’s weight loss potential, so feel free to share your thoughts and comments below to fill in any blanks I may have missed.
