phenq side effects

It is normal to be concerned about the possible side effects any drug can have on you, especially one that you can purchase over the counter. If you’re looking to lose weight, you may have come across the diet pill PhenQ. While the official website states that the product has a strong safety record with no side effects recorded so far, it is unlikely that such a tablet exists on the planet.

Supplement manufacturers often insist that their pills do not cause any side effects.

For the most part, they state that the use of natural ingredients makes the occurrence of a reaction improbable. However, because of how different genetic makeup and body types are, medications and supplements react differently for everyone.

PhenQ is no different. We’ll look into what you have to know about this diet pill and how to reduce the potential side effects.

According to the Food and Drug Administration (FDA) website, they do not approve supplements. It is therefore critical not to take ‘FDA approved facilities’ for an endorsement of the product by the same entity.

The same goes for the labeling.

Though each product is required to display the nutritional value of the content inside, the labels don’t require approval by the agency. The only requirement is that the labels be truthful and not misleading. Part of that measure is including the serving size and the nutritional value per serving.

The phrase ‘FDA approved facilities’ is equally misleading.

The organization does not “approve” facilities; it inspects regulated facilities as part of the authority they have. They do so to verify if they comply with manufacturing practice regulations. The companies that manufacture drugs, food, and most devices, both domestic and foreign, have to register with the agency.

For PhenQ, having FDA approved facilities means that, after inspection, they met the requirements that need to be adhered to produce the diet pills. Keeping this in mind lets you know that you are open to some risk given that it has not been reviewed and approved by FDA for its effectiveness and safety.

Just because PhenQ is not FDA approved does not mean that it’s unsafe. If there were existing complaints after the diet pill hit the market, the FDA would have research and monitor the supplement and those taking it. For this reason, one can assume that it is safe.

It also has 190, 000 satisfied customers around the world.

The company that produces PhenQ, WOLFSON BERG LIMITED has been running for over a decade and provides supplements to the industry. They state the use 100% effective ingredients for their products and base their formulas on scientific research.

Though the product can be considered safe, if you have underlying health concerns or an illness, you should visit a doctor. They are best placed to let you know if any of the ingredients could potentially affect you.

If you’re on medication, do not take this product before talking to your medical practitioner!

To get the most out of PhenQ and to safely lose weight, you require a lifestyle change. If you’re serious about shedding off the extra pounds, then you’re likely to do whatever it takes to do so and keep the weight off.

Though it’s a weight loss pill, using it for months or even years and not getting the results you want is an indication that there is something you’re not doing right on your end. Here are some tips to help shed and keep off the extra weight.


Eat the recommended amount of proteins, vegetables and fat. That means cutting out processed foods and sugar and sticking to mainly natural and organic foods. Fruits and high fiber foods should also feature in your diet to get the body you want even faster.

As always, take your time to chew the food. Also, do not starve or fast when taking this diet pill.

Most of the ingredients work by turning fat into energy, namely the α-LACYS RESET®, calcium carbonate, capsimax powder and L-carnitine Fumarate. When you don’t eat, these components will burn energy from your store reserves.

However, you are likely to experience unpleasant side effects when you do so. Even low-calorie diets can be problematic as well. Don’t obsess about the calories; the diet pill will help you burn them. Instead, focus on having nutrient-filled foods.


Preliminary studies indicate that dehydration can cause headaches. Should you experience headaches when taking this diet pill, it could be an indication that you’re dehydrated. However, there is such a thing as drinking too much water; scientific studies show that it reduces the kidney’s ability to function as a natural filter.

Not sure how much to take? Consuming a glass or two before meals and sipping throughout the day- or when your body says it’s thirsty, does the trick.


PhenQ has ingredients with thermogenic properties (the α-LACYS RESET®, caffeine, and capsimax powder), that is, the production of heat. Coupled with the other elements that break down carbohydrates and convert them into energy, your exercise workouts are likely to be more fruitful.

The extra energy will help you push harder during your cardio and strength training – the best way to lose weight and tone the body. You don’t have to hit the gym, just make sure you get moving.


PhenQ should be taken twice a day, one pill in the morning and another at lunch. This direction is due to the caffeine in the supplement. When you take it past 3 pm, it will likely cause sleep disruptions. If you don’t take caffeine, you might experience some side effects as your body becomes accustomed to the pill.

For those consuming coffee, should you encounter jiggers, restlessness or lack of sleep that you otherwise didn’t before taking the supplement, you might need to cut back of the coffee; getting a decaf would be better.

In each container, you’ll find 60 pills and are to take two daily, one in the morning and the other at lunch. That means you need a bottle per month. Payment is through American Express, Visa or MasterCard.

Thus far, the company has received a lot of praise from customers.

PhenQ clinical trials on their main ingredient, α-LACYS RESET®, has shown that a person can lose 7.24% body fat, 3.44% of the initial body weight and had a 3.80% muscle mass increase. These results demonstrate that the diet pill works. With no general reported cases of side effects, one can safely use PhenQ as part of their weight loss journey.

Should you experience mild effects, you can change your diet to something more nutritious and drink plenty of water. Though unlikely, see a medical practitioner when you experience more severe effects of an adverse reaction.

Overall, we hope to have addressed all your concerns about PhenQ; it proves to be a worthy companion in anyone’s weight loss journey.
