Don't know which gel to choose? 👇

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!

  • Improves blood flow
  • Reduces oxygen cost of exercise
  • Delays fatigue during exercise
  • Increases time to exhaustion
  • Supports faster recovery

Take 3 capsules with water approximately 30 minutes before exercise.

On non-training days, take 3 capsules in the first half of the day.

Attention! People who take medication for heart conditions or have an allergy to nitrates or nitrites should not take this product!

Used by Elite Athletes

I take Nitrates+ before races or high-intensity workouts. It gives me that extra edge in sprints and accelerations — I feel more explosive and can push harder for longer. It’s become a staple in my prep routine whenever I need to show up at my best.

Le Flochmoën Antoine

I use Nitrates+ as support for endurance during key training sessions, as well as for important races. They contribute to better blood flow and muscle efficiency, which makes me feel fresher, my legs lighter, and my pace more sustainable over longer periods. It especially helps me during intense speed workouts and marathon distances, where every additional percentage of performance matters.

Luka Bartolić

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

Who should use Nitrates+?

Perfect for any athlete looking to train harder, last longer, and sprint stronger.

Whether you're a cyclist powering through hill climbs, a runner pushing through sprint intervals, or a triathlete aiming to hold power through the final miles, Nitrates+ helps you go further with less effort.

Do you train consistently, race hard, and care about every watt? Nitrates are your next move.

How Does Nitrates+ Work?

Nitrates+ combines three natural nitrate sources (beetroot, red spinach, and arugula) with L-arginine HCL to boost nitric oxide production and improve performance by:

  • Widening blood vessels
  • Enhancing oxygen delivery
  • Increasing time to exhaustion


The result? More power for the same effort, stronger sprints, and faster recovery.

You’ll feel the first effects from day 1, but peak performance benefits build after 5–7 days of consistent daily use.

Beta vulgaris extract 10:1

Beetroot is naturally rich in nitrates, which the body converts into nitric oxide. For endurance athletes, this means improved blood flow, more efficient oxygen delivery, and reduced oxygen cost during exercise. The result is being able to hold your pace longer, push harder in intense efforts, and delay fatigue.

Red spinach extract (9% nitrates)

Red spinach is one of the most concentrated natural sources of nitrates. It supports higher nitric oxide levels, leading to better circulation, improved muscle efficiency, and lower perceived effort.

Arugula extract (10:1)

Arugula is another nitrate-rich superfood that boosts nitric oxide production, enhancing blood vessel dilation and oxygen delivery to working muscles.

L-Arginine HCL

L-Arginine is an amino acid that serves as a direct precursor to nitric oxide, helping to expand blood vessels and improve circulation. For endurance athletes, this results in more oxygen and nutrients delivered to the muscles, reduced fatigue, and stronger performance during long or demanding workouts.

Recommended Use

Take 3 capsules with water approximately 30 minutes before exercise.

On non-training days, take 3 capsules in the first half of the day.

Attention! People who take medication for heart conditions or have an allergy to nitrates or nitrites should not take this product!

Ottimo

Prendevo Absolute e mi son trovato molto bene. Ora aggiungo anche Nitrates+ e spero abbia le stesse qualità. Volevo però sapere se potessi coniugare l'utilizzo dei due integratori e se si come. Grazie

Certo che sì. Seguendo le istruzioni!
Absolute:
Il giorno di allenamento assumere 4 capsule 30-45 minuti prima dell'esercizio.

Il giorno di riposo assumere 2 capsule la mattina e 2 capsule il pomeriggio.

Nitrati: 30-40 minuti 3 capsule prima allenamento

Super Tabletten

Habe die Tabletten zweimal vorm Cardiotraining ( 30 Minuten vorher) eingenommen! Muss sagen ich fühlte mich fitter und hatte mehr Sauerstoff! Kann es bis jetzt nur empfehlen!
