At the time that this PhenUltra review was written, very little was known about this diet pill as no official website was available. Moreover, although the product was once sold at multiple sites, as of July 2020, the product could only be found for sale on eBay, where two bottles (a two month supply) could be purchased for roughly $25.00 + shipping.

Due to the fact that there is no official website and eBay was the only option for buying PhenUltra, this is a very good indication that this diet pill has been discontinued and it won’t be long before it leaves the market.

Potential Benefits

Among the different claims that have been made about PhenUltra and the potential benefits it can provide dieters include:

  • Appetite control
  • Boosted metabolism
  • Enhanced energy
  • Improved mood

Like most nonprescription diet pills that claim to deliver these benefits, the formula works best when it is combined with a healthy diet and regular exercise. It is meant to be used to help a person with their weight management strategy to achieve a long-term goal.

If it does work and delivers on these advantages, it has the potential to make sticking to a calorie restricted diet easier and help a person power through their day, supporting their efforts to remain committed to workouts.

Naturally, the only way to know how beneficial it may be to a dieter is to have a look at its ingredients.

PhenUltra Product Information

According to the supplement facts located on the back of the bottle, PhenUltra capsules are comprised of a propriety formula that is composed of:

  • Caffeine
  • Glucuronolactone
  • Phenylethylamine HCl
  • Synephrine Caprylate
  • Nettle Leaf Extract
  • Yohimbine HCl
  • Picamilon
  • Inositol Niacinate

The suggested dosage is to take 1 capsule before breakfast with water and 1 capsule after lunch with water. It is not recommended for users to take more than 2 capsules per day. However, anyone who has an existing health condition, or who is currently taking any medication, or who is pregnant or nursing, should first speak with their doctor prior to trying PhenUltra. In fact, even if you have no medical concerns, it is still wise for you to consult your physician prior to taking this weight loss supplement, just to be on the safe side.

A Formula Comprised of Several Stimulants

As you may or may not have noticed by observing the above ingredients, PhenUltra contains multiple stimulants (caffeine, yohimbine, synephrine, phenethylamine). Although these substances are likely to help boost energy, which can temporarily increase metabolism and burn calories, they can also cause adverse effects, particularly in those who have sensitivities to stimulants. Unwanted side effects may also be increased in those who combine this product with other stimulant foods and beverages.

With that said, some of these unpleasant side effects include, but are not necessarily limited to:

  • Rapid heartbeat
  • Jitters
  • Headache
  • Sleeplessness
  • Mood changes
  • Anxiety

Furthermore, it should be noted that these diet pills contain synephrine, a stimulant found within bitter orange. While this herb has been studied and some research has found that it may boost metabolism in some people and may be safe to consume in appropriate amounts on its own or with caffeine, other research suggests that combining it with caffeine may increase the risk of increased blood pressure, fainting, stroke, and heart attack in some people.

The bottom line is that not enough research has been conducted on synephrine on its own or in combination with caffeine to truly determine if it is safe or a beneficial treatment for aiding with weight loss.

There is Nothing Unique About This Product

In addition, the ingredients found within PhenUltra are not unique to this diet pill. Several similar appetite suppressing and energy boosting non-prescription weight loss pills contain these ingredients. Even though some studies have been conducted on each of these substances to determine their benefits for assisting in weight loss, there is not enough medical evidence to prove that any of these ingredients are effective in helping a person lose weight. In essence, there is no guarantee that taking PhenUltra will result in weight loss.

Ultimately, this is just one of many weight management aids on the market pretending to be a nonprescription phentermine alternative. Due to this fact, and the fact that PhenUltra has likely been discontinued, it would probably be a better option to find a more reputable OTC diet pill.


Phen700 (Phentemine 700) promises “fast and amazing results.” According to the bottle’s label, it is a “Pharmacy grade appetite suppressant dietary supplement.” This diet pill is also supposed to help improve sleep, increase energy and lower aches and pains.

The active ingredients in Phen700 include: Phenylethylamine, Synephrine, Caffeine, Nettle Leaf Extract, Yohimbine Extract, Insoitol Niacinate and Picamilon.

How do these ingredients benefit users of Phen700? The official website of the product says that Phenylehylamine (PEA) improves mood and increases alertness, which can be beneficial for improving exercise performance. Synephrine (bitter orange/citrus aurantium) is a fat burner that works best when combined with caffeine. Caffeine acts as a catalyst in Phen700, enhancing the effects of the other ingredients in the formula. It also raises energy levels and mental awareness.

Nettle leaf helps to reduce water retention, contains many vitamins and minerals and may also help to relieve joint pain. Yohimbine has been found to hinder a mechanism in fat cells that prevent weight loss. Inositol niacinate can help to lower bad (LDL) cholesterol and raise good (HDL) cholesterol when combined with proper exercise and diet. Picamilon assists the other Phen700 ingredients in helping users burn extra calories and prevent fat production.

Although this sounds impressive, the reality of this product is that not a single one of the ingredients it contains has ever been scientifically proven effective for weight loss. Research has shown that stimulants, like caffeine, are fat burners and can improve alertness, but boosting alertness and even fat burning does not guarantee weight loss.

Also, while synephrine does enhance the effects of caffeine, this may cause more harm than good. Not only does it increase the risk of unpleasant side effects like sleeplessness, jitters, rapid heartbeat, anxiety, upset stomach, etc., but the FDA also warns that it can increase the risk of serious cardiovascular effects including heart attack and stroke.

This product contains a diuretic (nettle leaf), which could increase the risk of dehydration and even heat stroke from exercise if not enough water is ingested. Furthermore, Phen700 has picamilon in its formula which is a drug and not actually a dietary supplement. Picamilon has not been approved by the FDA and does not meet the FDA criteria for compounds that are allowed in dietary supplements.

Another aspect worth noting is that according to the official product website, in America, Phen700 has proven in users an average 25 pound weight loss in just six weeks. While quite a bold and eye-catching statement, it would be more impressive if the website actually supplied facts or studies to backup this claim. Although the site does have positive testimonials, testimonials are not enough to prove the safety or efficacy of a product. In short: there is zero proof that users will lose any weight while taking Phen700, let alone 25 pounds in six weeks.

If you are interested in making Phen700 a part of your diet and exercise weight loss program, you are strongly urged to first speak with your doctor before taking this product.

When this review was written, a one month supply of Phen700 cost $67.00.
