What is Amplified Endurance Booster?

Need an endurance boost? Go the distance and improve your time with Amplified Endurance Booster! It's GNC's most effective endurance product ever! This clinically studied formula is proven to take minutes off your long distance time and make intense endurance exercise easier! This unique formulation combines the nutrients your body needs the most during endurance exercise to go the extra mile. Key features include....

Specialized Carbohydrate Blend-During intense long distance exercise, adequate amounts of quality carbohydrates must be available to energize your working muscles for the long haul. This formula contains two fast-acting carbs, dextrose and ribose, with a slower acting carbohydrate, maltodextrin, to provide sustained energy and blood sugar levels needed for maximum endurance performance.

10 Grams of Muscle Fueling Protein - While most sports drinks are made up of simply carbohydrates, studies show that a combination of carbs and protein during exercise can improve performance and better fuel your muscles for endurance exercise. That's why this formula is packed with 10 grams of high quality protein to better fuel your game.
Critical Amino Acids - Without a full amino acid pool, endurance performance can suffer. This product features Branched Chain Amino Acids (BCAA) to help preserve muscle glycogen stores and reduce protein breakdown during long distance activity. It also includes glutamine, which plays an important role in muscle function and hydrating muscle cells.

5 Electrolyte Blend - This thirst-quenching, hydration enhancer provides a 5 - electrolyte blend, all of which are lost through sweat during exercise. Replacing lost electrolytes is necessary to help regulate body fluids. Not getting the right amounts of fluid, electrolytes, and other minerals present in this top notch formula may lead to muscle cramping.

Vitamins and Minerals- Equiped with B-vitamins, this formula also supports carbohydrate metabolism and energy production. Plus, it's enhanced with calcium, which plays an important role in muscle contractions, and magnesium, which is necessary for muscle function

Health Notes

Adenosine Monophosphate

Adenosine Monophosphate
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Shingles and Postherpetic Neuralgia
Dose: Refer to label instructions
Adenosine monophosphate has been found to speed healing, reduce the duration of pain of shingles, and prevent the development of postherpetic neuralgia.(more)
Dose: Refer to label instructions
According to one report, about half of the people with porphyria cutanea tarda who took adenosine monophosphate saw complete alleviation of their photosensitivity.(more)
Shingles and Postherpetic Neuralgia
Dose: Refer to label instructions

Adenosine monophosphate (AMP), a compound that occurs naturally in the body, has been found to be effective against shingles outbreaks. In one double-blind trial, people with an outbreak of shingles were given injections of either 100 mg of AMP or placebo three times a week for four weeks. Compared with the placebo, AMP promoted faster healing and reduced the duration of pain of the shingles.1 In addition, AMP appeared to prevent the development of postherpetic neuralgia.2, 3

Dose: Refer to label instructions

Adenosine monophosphate (AMP) is a substance made in the body that is also distributed as a supplement, although it is not widely available. According to one report, 90% of people with porphyria cutanea tarda responded well to 160 to 200 mg of AMP per day taken for at least one month.1 Complete alleviation of photosensitivity occurred in about half of the people who took AMP.

Adenosine monophosphate (AMP) is an intermediary substance formed during the body's process of creating energy in the form of adenosine triphosphate (ATP) from food.
