People Who Buy This Also Bought
AMPlify your recovery and lean muscle-building goals with this revolutionary formula available in convenient great-tasting chews. Amplified Leucine Complex was developed with one of the most important amino acids for lean muscle building, leucine, along with the new and trending ingredients to fuel muscle recovery optunia and Sicilian Blood Orange Extract.*

Muscle-Fueling Amino
Leucine is one of the most important amino acids to fuel muscle growth, recovery and performance.* This crucial branched chain amino acid helps support the preservation of glycogen in the muscle.* When combined with protein, leucine has been shown to support strength and power workouts and may have more performance-enhancing benefits when compared to taking protein alone.* Leucine also helps spare the muscle tissue from breaking down from intense training.* Therefore, the body will be able to focus on more useful energy sources like carbohydrates and fats.*

Maintaining Insulin Balance
Opuntia extract (prickly pear cactus) has been shown to support a healthy insulin response.* Maintenance of insulin balance is crucial for supporting lean muscle development and recovery along with carbohydrate metabolism.* Together, opuntia and leucine have been shown to boost insulin post-exercise. Insulin is key for shuttling nutrients to the muscles and helps restore glycogen stores. A boost in insulin post-exercise plays a key role in leucine and amino acid absorption and delivery of nutrients to muscle cells to support anabolism and recovery.*

Protecting Muscle Cells
The exotic fruit extract, Sicilian Blood Orange, is becoming one of the most well-known supplements among athletes for its recovery and muscle cell-protecting benefits.* This rare extract will help protect muscle cells from toxic free radicals that attack muscle during intense workouts.* The Sicilian Blood Orange will also lower oxidative stress in athletes to support greater recovery.*

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.
