Alternatives To Phen24: PhenQ, Forskolin 250, Garcinia Extra


In an age when there are literally thousands of supplements available for weight loss, fat loss, fat burning, and other body-trimming needs, it’s easy to feel overwhelmed. Each one makes extraordinary claims, promising massive results with little or no work. Is there a product out there with a straightforward formula offering straightforward results?

The folks who make the weight loss supplement Phen24 believe they have such a product to offer. On the surface, their claims are similar to others. They even laud the product directly as weight loss in a bottle. This is a bold claim, to be sure.

Such bold claims raise concerns in the wary. First, are the claims accurate to the results of the product? Second, is the product safe? A previous chemical, phen/fen, claimed to be weight loss in a bottle. As we all know, this was linked to serious heart health complications.

However, Phen24’s site is full of highly positive, even glowing reviews from users. These worthies cite weight loss figures of 12-15 pounds per month, with at least one claiming to have lost 24 pounds over three months, or 8 pounds per month.

Specific claims made by the Phen24 people include:

  • Appetite suppression (reduce food cravings, and you won’t pack on weight through caloric imbalance)
  • Metabolism boosting (increasing the rate at which the body processes calories and burns energy)
  • Raising basal body temperature (related to the increase in metabolism, running the body hotter burns more energy)
  • Burning body’s stored fat reserves (fat is stored energy, so targeting it to burn will reduce weight and waistlines)

This all sounds well and good, but other products make similar claims about their supplements and unique formulas. Is this all so much smoke and mirrors, or is there something to this particular weight loss supplement?

Ordinarily, we would be quite skeptical of claims as dramatic as these. However, the sheer weight of reviews crosses over from simple anecdotes into strong correlation of evidence. Put less nerdily, so many people are testifying to the product’s efficacy that there is very likely something there.

Therefore, we have elected to research the product offered as Phen24 in order to see what ingredients are being used in this supplement. After all, the ingredients are what do the work, so it makes sense to know what we’ll be putting into our bodies.

Some of the Best Alternatives Similar to Phentermine reviewed at Outlook:

List of Phen24 Ingredients


Calcium: 105mg


One of the interesting things is that the makers of Phen24 have included calcium on their ingredients list in two forms, specifically listing each type rather than lumping them under the generic heading of “Calcium.” Specifically they have included dicalcium phosphate in an 80mg dose, and calcium carbonate in a 25mg dose, per pill.

A study by Dr. Robert Heaney, MD, had some strong things to say in favor of calcium intake regarding weight loss (or at least the prevention of weight gain.

Specifically he noted that women with higher dairy intake tended to gain the lowest amount of weight, contrary to popular assumptions. His studies concluded that increased calcium, up to 1000mg per day, can seriously hinder weight gain.

The study showed the effect was strongest among women who exercise and maintain a high level of calcium intake. Their bodies tended to burn more fat than those who either did not exercise, or who had a reduced calcium intake.

Calcium has a number of clearly demonstrated weight loss benefits.

  1. Increases rate of fat oxidation.
  2. Assists in body thermogenesis (making heat, which comes from burning energy)
  3. Assists the body in excreting dietary fat.
  4. Inhibits storage of body fat.
  5. Inhibits appetite.
  6. Increases fat breakdown.

This all comes with the usual caution against overdoing it, however. Excessive calcium intake can lead to kidney stones, constipation, and possible risk of heart disease. Make sure not to exceed safety limits set by your doctor.


Chromium Picolnate: 125 mcg


Chromium, combined with picolinic acid to assist absorption rate, assists the body in transporting glucose across the cell membrane. Basically, it brings sugar to the body’s cells.

Your body only needs miniscule amounts of Chromium, and the 125 mcg (that’s micrograms) in Phen24 is sufficient to meet the daily intake need. It is also linked to several weight loss claims.

  • Insulin Function Improvement

Insulin is the primary way your body regulates blood sugar. By helping regulate insulin function, a modest dose of chromium can help control the rate at which your body stores excess sugars as fat.

  • Appetite Suppression

A number of studies have linked Chromium intake (in the form of Chromium Picolinate) to controlling neurotransmitters responsible for appetite in the form of cravings. In essence, it “tricks” your body into feeling satiated, reducing the urge to graze on oversweet snacks.

Therefore, the value of Chromium Picolinate in this supplement is twofold, controlling the rate at which your body converts sugars into fats, and reducing the appetite to help you control the rate you put sugar into your body in the form of impulse or craving snacks.

Other Ingredients:

  • L-Carnitine Tartrate
  • Caffeine Anhydrous
  • Cayenne Pepper
  • Citrus Aurantium Extract
  • Coleus Forskolii Root Extracts
  • Artichoke Leaf Extract

Let’s have a brief but informative overview of the effects of these ingredients.

  • L-Carnitine Tartrate


A dipeptide of two amino acids, L-Carnitine is found in meat, dairy, some nuts, and several legumes. In Phen24, the Carnitine has been combined with Tartric Acid in order to improve the rate at which the body can absorb the compound.

The reason it was chosen is that it functions as a fat-burning supplement. Carnitine is used by the body to move fat from the bloodstream to the mitochondria. Mitochondria are the cell’s processing centers, converting fat acids into energy for the cells to use. When you feel your body heating up in cold weather, that’s your body’s mitochondria burning fat to keep your basal body temperature high.

It is also linked to higher fat burning rate during intense exercise. If you body burns x amount of energy during exercise in a given period, this can increase it by a percentage. It isn’t going to double it or anything so dramatic, but big losses begin with small efforts. It can also hinder muscle damage from exercise, reducing soreness. This allows you to exercise more for a given period, further increasing that loss of weight.

  • Caffeine Anhydrous


Most of us are quite familiar with the energy-boosting properties of caffeine. However, this is more than mere placebo effect or heightened alertness. Caffeine has been demonstrated to have certain thermogenic properties. Thermogenesis is, as stated previously, the process of the body burning stored energy to give active energy to the muscles. If you increase your thermogenesis rate, you burn more fat.

Studies have consistently shown a link that 150mg dose of caffeine can boost weight loss through thermogenesis and fat oxidation by approximately 2%. In short, if you take it at all you will increase your thermogenic rate, and if you take it before exercise you will significantly increase the benefits of the exercise’s weight loss factor. The 75mg of Ph. 375, taken twice a day, meets this 150mg requirement quite nicely.

  • Cayenne Pepper


According to nutrition scientist Richard Mattes, once said “The idea that one small change will reverse the obesity epidemic is simply not true. However, if some small changes are added together, they may be meaningful regarding weight management”.

Specifically he was referencing the fact that cayenne red pepper, when consumed regularly during and after meals, can have an observable small yet positive effect on the rate at which the body burns calories.

He stressed that the point of this was not to implement a miracle cure for weight gain, but rather to suggest that there are small steps that can be built up together for a big result, particularly if they are small, sustainable steps that are easy to take. Thus, the addition of a bit of red pepper to meals is a step similar to adding a walking routine of 1000 steps per day to your schedule. It doesn’t do a great deal on its own, but added to other efforts, it contributes to a bigger result.

Other studies have backed the doctor’s statements up. Red pepper has been linked to increased satisfaction with meals and fewer post-meal snack cravings.

All weight gain is due to caloric imbalance. More calories consumed than calories burned through exercise results in weight gain. Reducing cravings throughout the day means fewer calories consumed, and thus less fat to burn off.

The key ingredient linked to these effects is capsaicin, the element that makes peppers hot and spicy to our perception. The research suggests that capsaicin has thermogenic properties, speeding up the body’s metabolism. This results in more calories burned at rest and during exercise.

Again, the effect is modest on its own. Combined with other appetite suppressing functions and thermogenic boosting compounds, it adds up to a significant way to reduce caloric intake and retention. The net result is an easier time losing weight.

  • Additional Factors

Capsaicin has also been scientifically linked to:

  • Increased fat oxidation, breaking down fatty acids for weight loss
  • Reduction of abdominal retention of fat (or the “beer belly”)
  • Raise metabolism without increasing blood pressure.

The net effect is that it not only reduces weight gain through appetite suppression and fat burning, but also targets fat specifically in the abdominal section (one of the two most preferred places for the body to store excess body fat).

Citrus Aurantium Extract


Golden citrus or bitter orange, this particular citrus fruit has a long history in both aromatherapy and complementary and alternative medicine. It contains a compound called synephrine, which has a related but not identical effect to Ephedra, the long-banned and dangerous weight loss drug.

In a basic study of nine women, the subjects lost just under a kilogram of weight when exercising without the inclusion of Citrus Aurantium. Including Citrus Aurantium in their regimen raised their metabolic rate, demonstrating a thermogenic effect. This lead to an increased loss of weight, to 2.4 kg per week. That’s nearly triple the loss.

Admittedly this is a very small, almost anecdotal study. However, the fact it lead to such dramatic results shows promise for using it as a thermogenic weight loss assistant.

Coleus Forskolii Root Extract

An extract of the root of the herb Coleus Forskolii, this chemical is another with a long history in alternative medicine, specifically from the Ayurvedic or Indian tradition of folk medicine.

In a controlled trial of 30 overweight males, half were put on a 12-week regimen of this extract. As a result, they lost more fat than the 15 who were not taking the extract.

The study did show that overall weight did not change, indicating it was probably assisting in conversion of fat to muscle, which has more weight per volume than fat does. Regardless, removing excess fat from the body is as desirable as actual weight loss.

Artichoke Leaf Extract

Artichoke contains compounds linked to the body’s production and secretion of bile. Bile plays a significant role in the body’s regulatory process. Many of us have eaten a fatty meal only to feel the body go overboard in producing bile in an attempt to control it.

Studies have shown that a modest supplementation of 6g per artichoke powder to the diet can result in a 15% reduction in blood sugar (glucose) within 90 days.

As stated prior, sugar is calorie dense, and one of the key factors in fat production and weight gain. Regulating its intake can provide a strong weight loss effect. Further, excess blood glucose is linked to diabetes, which is not a desirable condition for anyone.

Side Effects

Remember that every compound or chemical put into the body has an effect on the body in some fashion. As a result, multiple side effects can potentially result from taking Phen24, just as with any other substance you take in. If someone suggests that a product is side-effect free, be skeptical in the extreme.

According to multiple sources, here are the common side effects associated with the ingredients used in Phen24.


Calcium carbonate in particular is linked to gastric distress such as stomach gas, leading to belching or stomachache. This effect is also noted in those who take calcium carbonate for heartburn/stomach acid control, as it reacts with the stomach acids and neutralizes them.


Side effects are quite rare for minor doses of chromium, but there have been some unusual, rare side effects noted. These include skin irritation, nausea, dizziness, cognitive impairment, and headaches.


Side effects listed include nausea, stomach upset, heartburn, dizziness, and in extremely rare reactions, seizures.


Insomnia, assorted stomach ailments, increased heart rate, and anxiety have all been linked to excessive caffeine intake. If supplementing caffeine into your diet, consider reducing your caffeine intake elsewhere (ie; don’t take it with your daily espresso!)

Cayenne Pepper:

Again, the stomach may experience irritation such as heartburn, as peppers have a known tendency to cause the body’s acid to react strongly. Other side effects are flushing, sweating, and a sense of overheating.

Artichoke Leaf:

Gas, stomach upset, and other gastric ailments.

Citrus Aurantium:

Be cautious taking this supplement with other stimulants. It can in some cases result in very serious side effects such as high blood pressure, heart attack, or stroke. These reactions are very rare, and tend to result from excessive stimulant intake. Again, limit intake of stimulants while taking Phen24.

Coleus Forskolii:

Conversely to the previous ingredient, CF can result in lower blood pressure, and in some cases might contribute to an excessive bleeding response to injury.

These all sound quite serious, but bear in mind they occur in an extreme minority of patients.

However, it is highly recommended you go to your doctor with the complete list of these ingredients and discuss their potential effects on your body before you take them. Always consult your physician before any supplementation regimen, because they know things about your health condition that the makers of a supplement may not. We like what we see about Phen24, but not enough to EVER suggest you avoid seeing your doctor!

Always trust your family physician’s insight and input.

Now, a qualifier to a previous statement. There are relatively few reviews of Phen24 available online that are not part of the official website. We chalk this up to the product being relatively new to the scene, and because many supplements are out there, making breakthrough on webpages somewhat difficult.

The reviews from Phen24 are universally good, though this is to be expected; why would they share negative reviews, after all?

That said, they make consistently strong claims, so there has to be something working for the product in addition to what we’ve seen above.

Where to Buy

As ever, we only recommend that you purchase Phen24 from the official website. Do not, under any circumstance, purchase from a 3rd party.

The fact is that there are scammers and liars out there, posing as resellers. Sure, the reseller you’re purchasing from may have the genuine product, but unless you have a chemistry testing set, how would you know?

By purchasing from the official site, you gain access to any money back guarantees, and the assurance that the product you’re getting is the product the company has produced.

Purchasing Options

There are multiple ways you can purchase Phen24 through the site, arranged by price into various packages.

 1 Box: $74.99

This might sound like a month’s supply, but remember that Phen24 is a twice-daily supplement according to instructions, so this option should last about two weeks. It’s a decent, though somewhat pricey, starter to using this supplement to see if it will help your weight loss efforts.

Interestingly, the company is offering a free bonus to your initial purchase. 5 training and nutrition guides are included; Introduction Guide, Supplements Guide, Workout Guide, Maintenance Guide, and Nutrition Guide. These are interesting, though the information can also be acquired elsewhere through research. Still, it is convenient to have them in one place.

Buy 2 Boxes, get 1 free: $149.99

This purchase will shave $8 off the price of two boxes, plus provide a third free, resulting in a total savings of roughly $75. This is a good deal for those who want to commit to a longer term process, lasting about a month and a half for most users following the instructions.

3 Boxes + 2 free + Free Advana Cleanse: $224.99

This is a deal for the long-haul users. Five boxes for the price of three, coming out to about 225 dollars. Given that five boxes would normally cost just about $375, this saves a decent amount of money overall if you plan to make Phen24 a regular part of your supplementation routine.

Shipping and Money Back Guarantee


Another bit of savings comes in the fact that these purchases come with free, worldwide shipping. This is a substantial savings, especially given the recent increases to international shipping rates.

Phen24 is also backed with a 60-day money-back guarantee. You simply have to contact the customer service team within 60 days and return any unused product in the provided packaging, and you receive a full refund.

The full refund is nice, but 60 days is barely enough time to make serious bodily changes that you know are going to last. It’s beneficial, but not exactly record-setting customer service if we’re being perfectly honest. It lines up very closely with other supplement money back guarantees on the internet.

To quote the official site, and to reiterate the above point:

“We are so confident in our product and services, that we back it with a 60-day money back guarantee. If for any reason you are not fully satisfied with Phen24, simply return the unused bottles in the original container within 67 days of when you received your order. We will refund you 100% of the product price – excluding shipping charges.”

“If you want to take advantage of our Special Savings by ordering multiple containers you can still try the product absolutely RISK-FREE for 67 days!”

“Simply return the first two empty bottles of your 60 day Phen24 supply and any additional unopened bottles of Phen24 within 67 days of receiving the order (sixty-day trial plus one week return shipping), and we promise that we will refund you the complete and entire purchase price, excluding shipping charges.”

“Please contact our customer service team on and we will get back to you with the return instructions within 48 Business Hours.”

Pros and Cons, broken down:


  • Significant, Potent Ingredients
  • Realistic claims based on incremental improvement, not wonder drugs
  • Significant, positive testimonials
  • Emphasis on links to scientific studies


  • At over $130 per month taking two pills per day, this is excessively expensive.
  • New product to the market, with very little industry penetration or word of mouth.
  • Limited reviews elsewhere.
  • Potentially VERY serious side effects from several ingredients (though admittedly extremely rare).

Cost Elaborated:

We really do feel that the money back guarantee is more of a fig leaf than a true consumer protection measure. The fact is that it can take 2 months to form the habits needed to change body weight. Given that this is very close to the time limit for the money back guarantee, this imposes a cost risk on the consumer; do you give it a little longer to see if it works and risk losing the guarantee, or do you give in and try something else?


Frequently asked Questions Phen24

Can Women Use Phen24?

Absolutely. The product is demonstrated to work in men and women alike. Results can vary between body types, as we all have different metabolisms and reactions. The broad rule of thumb is that the higher your body fat percentage, the faster your initial results will be. They will then gradually diminish a bit, toward the average.

How much Weight will I lose?

Again, this is not something that can be predicted perfectly. We all have different bodies and metabolisms. There should be some degree of weight loss simply through reduced eating due to appetite suppression, and through increased thermogenic processes.

This effect will be amplified when combined with changes to your dietary and exercise routines, of course. Phen24, as all supplements, works best as an enhancer to other efforts, not a solo-shot.

Should I change what I eat?

This is not something that we can answer safely. Your body has its own needs and preferences. Speak to your doctor if you are considering changing your diet. Some changes are obvious; cutting out heavy carbohydrate foods drenched in fat is probably a good idea. However, your doctor will better be able to answer dietary questions.

Do I need to exercise?

Increased exercise is good for almost anyone alive. You should be exercising already, at a reasonable level determined between you and your doctor. However, given the way the ingredients in Phen24 work, you should also be able to see some weight loss without increasing the amount of exercise you do.

This is because, as stated, it increases the rate at which your body uses up the energy it has stored, and it decreases your appetite. Fuel burned is fuel that isn’t put into storage as body weight.

How many pills should I take?

The instructions on the supplement suggest two pills per day, one before breakfast and one before lunch.

It is not advised you take additional pills per day, as the increase in caffeine can have adverse effects if taken in too large a dose. Further, do not take it before the evening meal (or after 3pm) if you value your sleep. Caffeine has a strong link to insomnia when taken too late in the day.

It is also suggested you reduce your intake of caffeine and other stimulants while taking the pill.

Is Phen24 safe?

In general, yes, it is safe to take this supplement. However, there are always risks associated with a strong mix of chemicals.

Do not take it if you are on antidepressants, are pregnant or breastfeeding, are under 18 years of age, have diabetes or cancer, have liver or kidney disease, or if your doctor indicates in any way your health condition precludes taking it. Be careful, and watch out for your health; you are your own best ally for healthy living.

Final Thoughts: Is it Safe to use Phen24?

Phen24 is not a miracle drug. Phen/Fen was a miracle drug, offering intense and amazing weight loss just by taking a pill. However, it was linked to heart damage and other health defects. Phen24 uses all natural ingredients that are far gentler on the system, but will have a reduced effect compared to wonder-compounds. This is the fact of life; everything is a tradeoff. You don’t get something for nothing.

If you are significantly overweight, a supplement can help you regulate your appetite and increase the rate at which your body burns energy. This will help you lose some weight. If you begin exercising as well, you will see an increased rate of weight loss. Combining the Phen24 supplement into a healthy lifestyle change is the best way to see the strong weight loss results you want.

Unfortunately, it is quite expensive. $130 a month is not an insignificant expense for most people, and it is a cruel fact that obesity is disproportionately higher among lower-income persons than among high-rollers.

The money back guarantee isn’t amazing, though it does offer some security for purchasers.

In short, we recommend you give this supplement a try with the 30 day or 60 day deals, and watch your timeline. It is composed of significant ingredients that are linked to strong weight loss results when put into a healthy lifestyle, so it does warrant a positive recommendation. Simply do not expect it to be a miracle wonder drug.

And as ever, consult with your doctor before making these changes, their insight may just be crucial to your efforts.
