    D-Aspartic Acid

    D-Aspartic Acid Guide

    Amino Amazing

    THE NEXT BIG THING

    D-Aspartic Acid (D-AA) is a non-essential amino acid. That means your body produces a functional amount of it internally.

    Amino acids are the building blocks of protein and serve various functions in the body during childhood development and throughout adulthood. D-Aspartic Acid plays a role in metabolic support.* According to one study, D-AA supplementation may also support increased testosterone levels.*

    D-AA And You

    THE SCIENCE OF D-ASPARTIC ACID

    D-AA is formed when the enzyme aspartate racemase converts an L-Aspartic Acid into D-AA in the testes and glands. It is one of 20 proteinogenic amino acids, which are the building blocks of proteins. It was discovered in 1827 by Plisson, a French pharmacist, by boiling asparagus and treating it with hydrochloric acid. (Crazy, right?)

    One human study testing D-Aspartic Acid suggested that the amino acid boosted testosterone and luteinizing hormone release when taken over a 12-day period.*

    D-Aspartic Acid is found naturally in the testes, pituitary gland and hypothalamus, all of which are involved in hormone production. The study found that D-AA has a role in the regulation of the release and synthesis of LH and testosterone in humans.*

    D-AA And You

    Boost Test Levels*

    REPLACE DIMINISHING TEST LEVELS*

    Aspartic acid comes in two forms, L and D. The l-aminos build tissue. But when l-aspartic acid combines with enzymes in the testes, it becomes a d-aspartic acid, which supports testosterone levels in the blood and prompts production of more.*

    A study discovered that D-Aspartic acid has specific effects on testosterone levels.* The patients in the study took 3 grams of D-AA per day for 6 days, then for 12 days. Researchers surmised that testosterone levels increased in all individuals who the compound being researched.*

    Boost Test Levels*

    D-AA: Age-defiant*

    AGED TO PERFECTION

    Many men over the age of 30 experience diminished testosterone levels. This could lead to increased body fat levels, decreased recovery ability, and problems with sleep. For some men, D-AA may help boost testosterone levels to promote hormone balance.*

    D-AA may support your fitness goals, but should be paired with proper diet and exercise.* Read and follow supplement directions carefully.
