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.
