Product Features

One thing GNC is noted for is revealing every ingredient included in a supplement formulated by the nutritional company. GNC Control ACS Appetite Control Support is no different. In addition to listing all ingredients, they go on to tell the dieter how much caffeine is included in each serving. At 180 mg, the supplement is average, but that is not necessarily a good thing. Taking this supplement twice a day would be the equivalent of drinking about five cups of coffee throughout the day. If the dieter does not commonly drink coffee, the boost of energy could be a bit too much causing jitters and headache.

There is also the chance this supplement will fade over time. The body quickly gets used to caffeine, so that burst of energy will soon fade to a brief push of energy and then fade out to nothing. More caffeine is needed to keep the same feeling which then leads to caffeine addiction.

Green tea and chromium are the best ingredients on the list. Chromium is proven to help regulate hunger by preventing sudden drops in blood glucose. Green tea is a metabolism booster and provides a long, proven list of benefits. The most effective ingredients are included in a proprietary blend, so the dieter does not know if there is enough green tea for the supplement to be most effective.

GNC Control ACS Appetite Control System sells for $39.99, but is on sale from the official website for $24.99. If the dieter chooses to purchase the supplement in a GNC store, the price may not be reduced.

Though we trust in the GNC name, this product is not the most effective the company has produced. GNC Control ACS Appetite Control System is not a supplement we would suggest a dieter try, based mostly on reviews from the GNC supplement website.
