Nitrates+ is a highly-efficient supplement designed to increase endurance. By widening your blood vessels, it allows more oxygen and nutrients to feed your muscles, resulting in a noticeable performance boost.

Combining three natural nitrate sources — beetroot, red spinach, and arugula (rocket) extracts — with L-arginine HCL, Nitrates+ enhances nitric oxide production. This results in improved blood flow, more efficient oxygen utilization (indirectly boosting VO2 max), and reduced fatigue.

Why L-Arginine HCL? Arginine HCL is a key amino acid involved in nitric oxide synthesis, further boosting circulation and enhancing oxygen delivery during training.

Increase endurance by delivering more oxygen to your muscles, faster!

Used by Elite Athletes

I use Nitrates+ before my hard training sessions and before competitions, this allows me to maximize blood flow and delay fatigue without having to consume liters of beetroot juice, which I digest very badly... the effect is truly amazing!

Émile Blondel-Hermant

Nitrates+ is a much easier way to get the benefits of beetroot juice without the hassle of prepping or drinking large volumes. I take it before threshold or long rides, and it feels like I can hold power with less perceived effort. It’s become a simple part of my pre-session fueling.

Marco Grittner

For someone like me who specializes in long distances, this is a product that should never be missing. It improves blood flow, reduces oxygen consumption, and delays fatigue — everything you need for sports. I usually take 3 capsules 30 minutes before exercise.

Cosimo Bertotto

I love the benefits of red beet, but not first thing in the morning. These capsules let me enjoy its effects without the taste, and I’ve definitely noticed an improvement — especially during long efforts.

Sara Ciapetti

Personally, I tried a combination of Fusion and Nitrates; this gave me consistent energy and better effort management. If i want to go for a KOM or a shirt effort Race, this is what i prefer, the right boost.

Alex Rigo
