Only a small percentage of dietary supplements are tested in gold-standard human clinical trials. Berkeley Life® Nitric Oxide Support has been evaluated in double-blind, placebo-controlled research demonstrating its ability to increase nitric oxide bioavailability in humans. The dietary nitrate ingredients used in our formulation are supported by a growing body of peer-reviewed clinical research validating improvements in vascular function, endothelial health, and blood pressure regulation.

The Impact of Clinical Proof

Double-blind, placebo-controlled trials (DBPCTs) are considered the gold standard in scientific research because they help ensure:

• Bias elimination
• Control for placebo effect
• Validated efficacy
• Safety and tolerability assessment

By studying the full nitrate formulation as it is consumed, Berkeley Life® ensures the product is evaluated for real-world effectiveness and safety—not just theoretical ingredient benefits.

Nitric Oxide Production

Berkeley Life® is formulated to increase nitric oxide through the dietary nitrate → nitrite → nitric oxide pathway. Unlike L-arginine-based supplements, this pathway remains active even when endothelial nitric oxide synthase (eNOS) declines with age.

• Clinical Trial Results: In a double-blind, placebo-controlled study, participants taking Berkeley Life® demonstrated significant increases in salivary nitrite and plasma nitrite compared to placebo. Test strip readings correlated with laboratory measurements, confirming improved nitric oxide bioavailability.

Vascular & Endothelial Health

Nitric oxide is essential for healthy blood vessel function. It supports vasodilation, circulation, and endothelial integrity—all of which naturally decline with age.

• Clinical Trial Results: In clinical research evaluating dietary nitrate supplementation over 12 weeks, participants showed improvements in endothelial function and reductions in carotid artery stiffness, a recognized marker of cardiovascular risk.

Blood Pressure Support

Nitric oxide helps relax and widen blood vessels, supporting healthy blood pressure regulation.

• Clinical Trial Results: Clinical studies of dietary nitrates have demonstrated improvements in systolic blood pressure and vascular responsiveness compared to placebo, particularly with consistent daily use over 8–12 weeks.

Energy & Oxygen Efficiency

Nitric oxide plays a critical role in oxygen delivery and mitochondrial signaling. Healthy nitric oxide levels support efficient energy production and muscle performance.

• Clinical Research Findings: Research on dietary nitrates has shown improvements in oxygen utilization and exercise efficiency, including reduced oxygen cost during physical activity.

Aging & Nitric Oxide Decline

Nitric oxide production naturally declines with age due to oxidative stress, hormonal shifts, and reduced enzyme activity. Berkeley Life® provides a nitrate-based pathway that supports nitric oxide production independently of age-related enzymatic decline, offering measurable vascular support as the body’s natural production decreases.
