D-AA: A Natural Supplement To Increase Testosterone

D-AA ( Increase Testosterone)

 High Quality Naturally Occurring Amino Acid (found in meat, oysters, casein and corn protein) Scientifically Shown to Increase Testosterone Levels without the Side-Effect of Increased Estrogen.

Proven Nutrition’s D-AA contains ultra-high purity D-Aspartic Acid Calcium Chelate that improves absorption and efficacy. When used daily, the active ingredient in D-AA has been scientifically shown to:

  • Increase Testosterone Levels
  • Improve Male Fertility

Great Add-Ons to D-AA:

  • CORE: All-Natural Drink Mix for Every-Day Health and Refreshment
  • BETA: For added Exercise Endurance and Recovery
  • CITRULLINE: Support Cardiovascular Health and Endurance
  • HEAL: Maintain Healthy Joints and Reduce Inflammation
  • CREA-HCL: Ultra-High Purity Creatine Without Bloating

D-Aspartic Acid supplementation has been scientifically shown to benefit male hormone and fertility health by the follow mechanisms:

  • D-Aspartic Acid stimulates the release of luteinizing hormone, follicle-stimulating hormone and growth hormone.
    • Luteinizing hormone stimulates the testes to produce testosterone.
  • D-Aspartic Acid helps overcome a limiting step during testosterone production in the testes.
  • D-Aspartic Acid improves sperm quality.

The mechanism of D-Aspartic Acid supplementation stimulated increase in testosterone has not been shown to increase estrogen levels. This is a significant advantage for the testosterone increasing mechanism of D-Aspartic Acid given increased estrogen is a dangerous side-effect commonly seen with the use of pro-hormones or anabolic steroids.
