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.†

NAD+ levels in the bloodstream are determined by a delicate balance between production and consumption.† By targeting NAD+ consumption, the compounds in Shield help ensure that your NAD+ reserves are used efficiently, effectively prolonging your youthful vitality and energy.†

“Together, this highlights that a multi-target strategy for NAD+ restoration such as the use of a precursor in combination with inhibitors and/or activators acting at other key points in the NAD+ network may be the optimum approach to NAD+ restoration.” (1)

Bioavailability is how much of a nutrient your body can actually use. Standard formulations of HLA, PEA, and AKG, are quickly broken down after ingestion.(8, 9, 10) The efficacy of vitamin C decreases as the dosage increases.† (11) Shield uses an advanced liposomal delivery system designed to improve the bioavailability of each natural compound, created for better absorption, and a slower release into the bloodstream.†
