Everybody aspires to have a fit and toned body, but it can be tricky for some people to lose weight. Major reasons like hormonal issues, digestive problems, medications, hereditary qualities, etc., play a big part in this. 

That’s why many people look to weight loss medications to enhance their diet and speed up weight loss.

What kind of product is Phentermine?

Phentermine is a drug used in combination with diet and exercise to boost weight loss. It is a short-term medication for obese people over the age of 16. The dosage is individualized based on the user’s body mass index and health.

It suppresses your appetite and makes you feel fuller for longer. However, its effectiveness directly depends on three other factors, namely: exercise, caloric restriction, and behavioral modification.

The USA approved phentermine first in 1959; by 2019, it was the 158th most-prescribed medicine in the country, with over 3 million prescriptions. Doctors do not recommend phentermine to people with health conditions like hypertension, hyperlipidemia, diabetes, glaucoma, et cetera.

It’s best to start with the lowest effective dose to prevent aggravated side effects like dry mouth, agitation, shivering, and prickling sensation in hands or feet.

Why do people seek alternatives?

Phentermine may be effective, but it is not without its fair share of side effects. It interferes with different bodily systems, including:

  1. 1
    Cardiovascular System: It can cause regurgitant cardiac valvular disease, tachycardia, palpitations, ischemic events, and high blood pressure;
  2. 2
    Central Nervous System: It can cause euphoria, psychosis, headaches, and overstimulation;
  3. 3
    Gastrointestinal System: It may also cause diarrhea, ischemic colitis, dryness around the mouth, constipation, and unpleasant taste.

Apart from its general side effects, it is also unsafe for pregnant and lactating women. In rare conditions, phentermine may even cause urticaria, a type of skin rash.

As it is an amphetamine or a mood-altering drug, its side effects last even after you stop taking it. Discontinuing use may cause social dysfunction, anxiety, and an inability to experience pleasure. 

Considering such grave side effects, people are now turning to safer and low-risk alternatives.

Over-the-counter vs. Prescription drugs

Prescription drugs are only available at pharmacies to people with a prescription from a relevant doctor. On the other hand, Over-the-counter medicines do not require a prescription and can be bought off-the-shelf in stores. Some drugs can be both prescription and OTC. 

In the US, FDA regulates prescription drugs through the NDA (new drug application) process. For non-prescription drugs, however, the standard is the OTC monograph booklet containing all of the approved ingredients’ names. FDA clears the drugs that conform to this book for sale without further evaluation.

What effects are we aiming for?

People should have access to weight loss medications without risking their health. Therefore, we created a list of the best phentermine alternatives with positive results and minimal side effects.

These products will help you lose weight quickly – one pill at a time, without having you go through the heavy side effects of Phentermine!

What ingredients are commonly found in Phentermine alternatives?

Some of the most common ingredients in phentermine alternatives are glucomannan, green tea extract, caffeine, and caffeine anhydrous. Glucomannan acts as ‘empty calories’ and makes you feel fuller.

The rest of the ingredients perform a variety of functions and work together to create the ideal fat-burning environment in your body. This is done by increasing the body’s core temperature, inducing thermogenesis, and releasing particular hormones and enzymes.

Our Top Choice

When it comes to weight loss medications, you won’t find a ‘one size fits all product. Every person has a unique hormonal cycle, body chemistry, eating, and activity habits. So, where a product might work for one body type, it may fall flat for the other. 

Then how is PhenQ the best?

PhenQ provides a sustainable way to lose weight. This supplement adjusts your metabolism, so you don’t gain weight even after you stop taking it. In addition, because it isn’t super expensive, unlike other supplements, you can save a lot of money by buying it in bulk. 

Phentermine suppresses appetite by decreasing the levels of norepinephrine in your body. This works, but there’s a catch. According to numerous studies and personal testimonials, low levels of norepinephrine interfere with our fight-or-flight function, resulting in agitation, irritability, and jitteriness. 

On the other hand, PhenQ contains glucomannan which swells in your stomach and provides the same benefit without causing jitteriness or mood swings.

Finally, its trademarked ingredient, α-Lacys Reset, contains alpha-lipoic acid, or ALA, a naturally occurring antioxidant that provides energy by breaking down carbohydrates in the body. PhenQ maximizes ALA’s power by coupling it with Thermogenics like capsimax powder and caffeine.

It is formulated to provide the best possible results with minimum side effects.
