How Did Waterex Start?

The introduction of the supplement cannot be determined easily, but it has been produced as a regular product of GNC for a while. GNC used as a scientific formula which regulates water and fluid levels in the body. GNC Waterex employs a natural blend of various products, enhanced by magnesium and potassium, which aim to help with balancing water in the body.

Waterex claims


Waterex Claims

  • GNC’s Waterex Pill is a water retention pill. They claim that it is scientifically formulated and acts as a health supplement to support and maintain the water balance in the user’s body.
  • It is an all-natural supplement.
  • Its components include vital nutrients such as potassium and magnesium.
  • The pill works through regulation.
  • The pill regulates fluid levels.
  • Its formula includes a proprietary blend of antioxidant-rich fruit and herbal extracts.

Waterex Ingredients

GNC claims that Waterex pills are made of a propriety blend of anti-oxidants, rich fruits, and herbal extracts.

Waterex ingredients include:

  • Cornsilk
  • Parsley herb powder
  • Fennel seed
  • Uva ursi extract
  • Hydrangea root powder
  • Garlic clove
  • Elderberry fruit
  • Horsetail rush stems

All of these are considered to be diuretic ingredients. Corn silk removes excess body tissue fluid. Parsley herb powder is a very fast-acting diuretic which has long been used for such purposes. Horsetail rush stems are used to prevent edema, the swelling of body parts.

Electrolytes are an essential component of the formula. Garlic clove, juniper berries, parsley herb powder and corn silk, are all ingredients used for herbal remedies.

Garlic Clove

Also known as allium sativum, garlic is a spice that is used for seasoning dishes all over the world. This includes regions such as Africa, Asia, Europe and the Mediterranean. It has also been used in traditional medicine since Ancient Egypt. Garlic has a very pungent smell and it produces a chemical called allicin.

What is it Supposed to Do?

Garlic is said to help with a number of health conditions. Some of these include athlete’s foot, jock itch, ringworm, hardening of the arteries and overall heart health. This herb may also help with fat reduction.

Clinical Research

According to one study published in The Journal of Nutrition in November 2011, “Researchers looked at the effects of garlic and fat storage on mice. The mice were fed a high-fat diet for eight weeks to make them obese. The mice were then given either a garlic supplement or placebo for seven weeks. The mice that were fed garlic experienced a reduction in body weight and fat, while those on placebo did not. The mice on garlic also had higher body temperatures, which suggests that garlic has a fat-burning effect that can be utilized in weight-loss.”

Parsley Herb Powder

Parsley is an herb that is native to areas like Tunisia, Algeria and southern Italy. It’s considered a vegetable and spice, and it’s commonly used in American, European and Middle Eastern cooking. This ingredient is also found in some diet supplements.

What is it Supposed to Do?

Parsley is used in some supplements to help increase urine production. This way you urinate more frequently, which may help reduce bloating and excess water weight. This herb provides vitamins A and , as well as plenty of iron, vitamin K and vitamin B9.

Clinical Research

“A study published in the Journal of Ethnopharmacology in March 2002 recorded the effect of parsley seed extract on urine output in rats. The experiment found that rats that drank parsley seed extract produced significantly more urine over a 24 hour period than those that drank water.”

Uva Ursi Extract

Sometimes called arberry or bearberry, uva ursi is a plant that has been used in some traditional medicines since the 2nd century. It is an evergreen shrub that is native to some parts of Europe, North America, Siberia, the Iberian Peninsula and the Himalayas.

What is it Supposed to Do?

There are numerous diet pills and internal cleansing supplements that contain uva ursi extract. This herb is typically claimed to increase urination. This may help reduce bloating and excess water weight. It might also assist with more regular bowel movements.

Clinical Research

The University of Maryland Medical Center states, “Researchers have discovered that uva ursi’s ability to fight infection are due to several chemicals, including arbutin and hydroquinone. The herb also contains tannins that have astringent effects, helping to shrink and tighten mucous membranes in the body. In turn, that helps reduce inflammation and fight infection. Today, uva ursi is sometimes used to treat urinary tract infections (UTIs) and cystitis (bladder inflammation).” Other than losing water weight, there is no strong connection to weight-loss.


How Does Waterex Work?

This water loss retention aid is an electrolytes-based formula. Electrolytes are either positive or negative. They carry their charge and transmit electrical impulses. They transmit nerve signals and help with contracting muscles.

Electrolytes help maintain the correct balance of body fluids. They also regulate the acid-base balance of bodily fluids. It is imperative to replenish our electrolyte levels continuously. Daily foods contain electrolytes which work to keep the fluid balance but, usually, these are discharged through sweating. We can also lose these electrolytes through exercise, or during an illness.

Electrolytes should be replaced. That is precisely what Waterex is designed to do. Maintaining a proper balance of replenished minerals and nutrients can help users control their body fluid levels even if they are undergoing vigorous training, exercise or a special diet.

Waterex cannot be considered to be a conventional method of losing weight, but it does claim to help maintain a healthy body while working towards a specific weight goal. Its goal is more directed towards maintaining a healthy body than losing a few extra pounds. It only helps with excess bloating if that is a true hindrance.

Does Waterex Work?

Water retention is a process that can be carried out with the help of natural ingredients. Waterex combines these natural products into a single pill. This issue can be helped with dietary supplements.

Users should be careful to use products that contain natural ingredients and are considered to be safe and effective. Any water retention supplements should also be good electrolyte balancers. Consider the electrolyte balance of any product before taking it.

Waterex contains Magnesium and Potassium, both of which are vital electrolytes. According to the National Library of Medicine, both main components of the supplement, B6, and magnesium are quite helpful in reducing water retention.

Does Waterex Work

They help to balance the levels of fluid in the body. All other ingredients are natural and work alongside these two to remove excess body fluid. Remember that it does not in any way help to reduce fat. However, claims state that Waterex removes at least 20lbs of extra water.

The supplement also contains a combination of uva ursi and juniper berries, both of which are said to aid in removing up to several pounds of water weight. These ingredients have not yet been clinically proven to reduce fat or boost metabolic rates effectively.

Waterex should be used with a physician’s permission since it can deeply affect bodily functions if not taken correctly. Such supplements can cause dehydration if an adequate amount of water is not consumed. Waterex is not designed for long-term use.

Benefits & Results

Waterex Benefits and Results

The official website of GNC Waterex does not claim that Waterex is an effective weight-loss supplement.

Water weight is merely the first part of losing extra weight, and it is also the first part of gaining weight again. Continuous weight loss is only possible if a user does not stop using Waterex which is not feasible and should not be attempted. The formula of Waterex is quite limited in its use. If you combine the benefits of Waterex with other supplements, it may increase weight loss.  It is inexpensive, and all its ingredients are all-natural products.

Waterex may be used as an effective supplement for the reduction of excess water in the body, which can add to overall body weight. Even though this product is labeled as a weight loss product, it is not ideal enough to lose weight permanently. Losing excess body water does not help with long-term body weight goals.

The supplement has a 4-star rating on various websites, and its reputation reflects its manufacturing company, GNC, which is a well-known company. Waterex is available with a 30-day money-back guarantee by the company.

“Great for quick water loss to look trim. – This product works great and you see slimming results within just a few days. But don’t think this is some diet pill. This will just cause you to loose water weight and make you look trimmer. It’s great for that final holiday look. Start taking about 2 weeks before vacation, and during and you’ll look great. I’m not a doctor or anything though, just letting you know what I do.”

Bottom Line

The Bottom Line on Waterex

Do you want to run out and but Waterex? Well, we like that we found some favorable customer comments and the price seems reasonable, but the lack of research showing it helps with weight-loss is a bit concerning. We’re also skeptical about this one because customers are talking about negative side effects and the supplement not working.

If you are looking to shed more weight, we suggest going with a program using clinically-tested tools that are shown to work.

Among the best programs we’ve researched this year is one called Noom. The program uses the education, talent and experience of medical doctors and nutritionists to guide the user through clinically-proven weight-loss method that are shown to work to help you lose weight and keep it off.

Also, the makers of Noom are offering a free trial. This a great sign of confidence in their program.

    • tina

      will it get rid of the water am holding in my body, my feet/sngle were swelling

  • Karen Parr

    Worked for me! I’ve lost 19 pounds and do not bloat. My liver enzymes are elevated, though….so not sure of its safety. Haven’t discussed that with my doctor yet. I was also fasting every other day, but on those days, I’d often have a couple drinks with a friend. So, not sure, but my initial reaction was and still is that it worked for me.

  • Waste of energy and money
    Kayla (Verified Purchase)

    Used it according to the label. When from barely working out and eating out 3-4 times a week to eating clean and working out 5-6 times weekly. Finally started drinking the recommended amount of water, and thought this would help regulate me. No changes, no improvements, receipt got thrown away. Waste of energy and money.
