The GNC GNC Pre-Diet Cleanse is an herbal supplement aimed at preparing the body for a new weight loss plan. According to the product description, dieters can expect hunger to be reduced and a sense of feeling fuller as part of the GNC GNC Pre-Diet Cleanse. There is also reference to gently cleansing the body, which could mean there are natural laxatives in the supplement. The body does not typically need any preparation to lose weight, but we will look at the ingredient list before making a decision.

List of Ingredients

Purified Water, Fructose, Fruit and Veggie Blend (cranberry extract, Acerola Berry Extract, raspberry juice crystals, coconut, Pomegranate Extract, Pure Lemon Juice Concentrate, blackberry fruit extract, cranberry fruit extract), Trace minerals, Cleansing Blend (Soy Sprouts, Aloe Vera Gel, Barley Malt, Licorice Root Extract, Eleuthero root extract, Astragalus Root, Barley grass, Chlorella Algae, Chicory Root, Jerusalem Artichoke Tuber, Mung Bean, Wheat Berry, Jasmine Tea Extract, Japanese seaweed), Fiber Blend (Brown Rice, Digestion Resistant Maltodextrin (Soluble dietary fiber), Soybean Fiber, Oat Fiber.

Product Features

The GNC GNC Pre-Diet Cleanse is a 48-hour program that claims to help dieter prepare the body for weight loss. The ingredient list starts out with sugar, which is not commonly an ingredient dieters want to intake when trying to lose weight. There are 65 calories per serving and the suggested dose is four times per day. That adds up to more than 250 calories extra per day when using the GNC GNC Pre-Diet Cleanse.

As for cleansing ability, fruit juice and aloe vera are two of the biggest cleansers in the supplement. Fruit juices are commonly recognized as natural cleansers, though typically avoided by dieters due to high calorie content. Aloe vera is a natural laxative that will increase bowel movements.

In addition to natural laxatives, the GNC GNC Pre-Diet Cleanse also packs several sources of fiber into the formula. Fiber blend, soybean fiber and oat fiber are specifically listed in the ingredients. When taking in additional fiber, dieters should always drink more water to prevent the bulk forming laxative from causing constipation.

GNC GNC Pre-Diet Cleanse sells for $29.99 and is available online for $19.99. Dieters claim the product tastes good and goes down easily.

Cleansing is a personal preference, but we tend to believe cleansing and weight losses are two different things. Weight loss requires a boost in metabolism and appetite suppression and this supplement will not offer either to the dieter.
