GNC X12 Review
What You Should Know
GNC is a supplement company with a long reputation for quality products. The GNC X12 product is designed as a metabolism booster with a thermogenic blend that will help dieters burn calories more efficiently. While thermogenics are a benefit in a weight loss supplement, we will look at the GNC X12 formula more closely to see if it can deliver on its promises.
This product claims to help you burn twelve times more calories than you would burn without a supplement. GNC also promises that their X12 formula will support improved endurance and performance. Unfortunately, the company does not appear to provide any scientific evidence or clinical research to support these claims. The lack of information makes us wonder if this formula really is as good as it says or if the company is luring consumers into purchasing their product based on unsupported claims. We are pleased to find that GNC provides a complete ingredient list for products so customers can decide for themselves if the formula is really as potent as it says.
Ingredients
The GNC website includes a complete listing of product ingredients, which includes Caffeine, Black Pepper Extract, Capsicum Fruit Extract Bioperine, Cellulose, Titanium Dioxide (Natural Mineral Whitener), Gelatin, Artificial Colors (Blue 1, Red 40). The company states that there are no artificial flavors, starch, sodium, wheat, gluten, corn, soy dairy or yeast in the formula. This means that the supplement is appropriate for many consumers, even those with dietary restrictions.
Caffeine is a standard ingredient in thermogenic formulas because it can boost the metabolism and increase energy. However, there are safe and unsafe levels of this substance and too much of a good thing can result in nervousness, jitters, irritability and insomnia. Black pepper extract and capsicum may have some thermogenic properties, but we believe there are more effective products available for this purpose.
Product Features
We are disappointed in the fact that GNC does not appear to offer any sort of money back guarantee on their products. We believe that this policy shows confidence in the product by the manufacturer and offers consumers the chance to try new formulas risk free. The product sells in GNC stores and on the company website for about $25 at the time of this review. This is a significant savings over the original price of almost $50 per bottle.
Advantages
- GNC X14 is a thermogenic that can boost the metabolism and burn calories.
- The product is currently offered at a discounted price on the company website.
Disadvantages
- The thermogenic ingredients may not be the most effective.
- There isn’t anything in the formula to act as an appetite suppressant.
- The company does not appear to offer a money back guarantee.
Conclusion
While we like the ideas of thermogenics in a weight loss supplement, we are not convinced that the substances in GNC X14 are the most potent ones available. We would urge consumers to look for top quality products and ingredients to get the biggest bang from their weight loss buck.
