Shield blends key compounds that support NAD+ levels by targeting NAD+-consuming factors associated with aging, such as oxidative stress and the accumulation of old cells.†

Each ingredient plays a vital role in limiting NAD+ consumption and supporting the body's anti-aging defenses:

  • Vitamin C: An essential nutrient with antioxidant properties that protect cells from damage caused by free radicals. Vitamin C is also important for immune support, skin health, and heart health.†
  • Calcium Alpha-Ketoglutarate (CaAKG): A molecule that plays a key role in energy production, cellular repair, immune system balance, and protein synthesis.†
  • Palmitoylethanolamide (P.E.A.): A naturally occurring compound that interacts with receptors in the body, potentially contributing to the regulation of physiological responses.†
  • Hyaluronic Acid (HLA): A natural molecule that maintains skin, joint, and eye hydration and lubrication. HLA plays an important role in tissue repair. It has also shown to improve the appearance of skin.†
