A different way to boost nitric oxide

Nitric oxide tells blood vessels to relax and widen, allowing more oxygen-rich blood to reach working muscles. SwissRX Nitric Oxide has been one of the most trusted ways to support that system, and for good reason: It works. A lot of athletes (Matt included) have made it a permanent part of their routine.

Berkeley Life Nitric Oxide Support is new to The Feed and takes a different route to the same result. It’s worth understanding the difference before you decide what’s best for you.

Two different pathways

Most nitric oxide supplements, including SwissRX Nitric Oxide's core formula, work by stimulating an enzyme called nitric oxide synthase (NOS), the body's natural NO-producing machinery. That approach works well, but the enzyme itself becomes less responsive with age, so its effectiveness can fade over time.

Berkeley Life skips that enzyme step entirely and uses the dietary nitrate pathway instead. Nitrate from beetroot and potassium nitrate converts directly into nitrite then into nitric oxide—a conversion that doesn't depend on enzyme activity and stays effective regardless of age. The dose is measured to match the nitrate equivalent of 7oz of beetroot, delivered in two capsules instead of a plate of vegetables.
