Nitrates+

£24.99 £17.99

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 rocket (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!

What is Nitrates+?
Nitrates+ is a nutritional supplement designed to improve endurance performance, increase power output, and enhance recovery by supporting blood flow and nitric oxide production during exercise.

Who should use Nitrates+?
Nitrates+ is intended for endurance athletes who want to improve oxygen delivery, delay fatigue, and boost performance in sprints, long sessions, or races. It can also support faster recovery after intense workouts.

How does Nitrates+ work?
Nitrates+ combines beetroot, red spinach, and arugula extracts with L-arginine HCI to increase nitric oxide production. Nitric oxide relaxes blood vessels, improving circulation and oxygen delivery to muscles. This can enhance exercise efficiency, reduce oxygen cost, delay fatigue, and increase time to exhaustion.

When should I take Nitrates+?
On training or race days, take 3 capsules of Nitrates+ with water about 30 minutes before exercise. If you have two exercise sessions in the same day, take the Nitrates+ dosage before the first session. On non-training days, take 3 capsules in the first half of the day.

What do the ingredients in Nitrates+ do?
Nitrates+ contains a blend of ingredients that work together to improve endurance performance.

  • Beta vulgaris (beetroot) extract: Natural nitrate source to improve blood flow and endurance.
  • Red spinach extract: Provides nitrates to enhance nitric oxide production and delay fatigue.
  • Arugula extract: Additional nitrate source to support circulation and oxygen delivery.
  • L-Arginine HCL: Amino acid involved in nitric oxide synthesis, boosting vascular function and nutrient delivery to muscles.


Are there allergens in Nitrates+?

Nitrates+ may contain traces of oats, barley, wheat, fish, milk, and soy. 

Is Nitrates+ vegan?
Yes. Nitrates+ uses vegan capsules and contains no animal-derived ingredients.

Does Nitrates+ contain caffeine or stimulants?
No. Nitrates+ works through nitric oxide production and improved blood flow, not stimulants.

Can I stack Nitrates+ with other supplements?
Yes. Nitrates+ can be safely combined with most fueling gels, drinks, protein powders, vitamins, and recovery products. It can be safely taken with L-Carnitine Tartrate, Fusion, Absolute, Nitro Boost, and Cordyceps.
However, you should always check for overlapping ingredients and consult a healthcare professional if combining multiple supplements.

Are nitrates harmful for the body?
No, nitrates from vegetables are not dangerous if consumed in normal amounts. The risk exists only for infants (up to 6 months). Nitrates can also pose a risk to adults if taken in extremely high doses (e.g., more than 1 g of active nitrates per day). However, this is far higher than provided by the recommended serving of Nitrates+.

Can I use Nitrates+ every day? 
We recommend taking Nitrates+ for 7 days before an important race, event, or training session. It is not meant to be an everyday supplement. However, there is no health reason you could not take it regularly. 

Are there any side effects of Nitrates+?
Nitrates+ is generally well-tolerated and does not cause side effects in most healthy adults. However, some individuals may experience bloating, worsening of hemorrhoids, changes to heart rhythm, a slight drop in blood pressure, mild gastrointestinal discomfort, or a temporary pink/orange coloration in urine or stools, which is harmless.  

Can I use Nitrates+ with medications?
People taking heart medications or with conditions affected by nitrates/nitrites should not use Nitrates+. Always consult a doctor before combining with prescription drugs.

How quickly does Nitrates+ work?
Some benefits of Nitrates+ may be seen within one to two hours of taking it. However, sustained benefits and performance increases usually require at least three weeks of use. 

Does Nitrates+ increase VO2 max?
Nitrates+ can indirectly increase VO2 max. By improving oxygen delivery and reducing oxygen cost during exercise, Nitrates+ supports more efficient use of oxygen, which can enhance endurance performance.

Should I take Nitrates+ on non-training days?
Yes. Take it in the first half of the day on non-training days to support baseline nitric oxide levels and vascular health. It can also help with recovery. 

Is Nitriates+ WADA-compliant?
Yes. Nitrates+ is free from banned substances, regularly checked, and manufactured in a GMP-approved facility with the highest ISO 22000 standard. Furthermore, our suppliers also have a certificate confirming that their products are free of impurities. 

How long does Nitrates+ remain effective after taking it?
After taking Nitrates+, plasma nitrate levels typically remain elevated for 6–8 hours. However, factors like metabolism, genetics, health, and gut flora all affect individual response. 

How many nitrates does Nitrates+ contain per serving? 
There are 63.5 mg of nitrates per serving (3 capsules) of Nitrates+. 

Are there any studies on the effectiveness of Nitrates+?
There are no independent studies on the exact formula in Nitrates+. Scientific studies cost a lot of money and independent funding is not yet available. However, there are numerous studies on the individual ingredients, many of which are very positive.

Do I have to swallow the capsules of Nitrates+? Or can I open the capsules and mix them into water?
Nitrates+ capsules are not enteric-coated. You can open the capsules and mix the contents with water, juice, or a smoothie. This will not affect the efficacy, release, or absorption of Nitrates+. 

Don’t nitrates need to be held on the tongue to be effective? 
While it’s true that some conversion of nitrates to nitrites happens in the mouth via oral bacteria, the effect of holding Nitrates+ on your tongue for a few seconds is very small. Most of the supplement’s benefits come from digestion and absorption after swallowing. For convenience and to avoid the unpleasant taste, it’s recommended to simply swallow the capsules.

Curious to understand whether Nitrates should be

Curious to understand whether Nitrates should be taken religiously every day or only 30 mins prior to endurance training?

Thanks for the question, Steve! Nitrates+ is best used consistently rather than just 30 minutes before training. Taking it regularly can help build up nitrate levels, while taking it before a session can also be useful. For the best approach, we’d recommend following the guidance on the product page or dropping us an email and we’ll be happy to help.

Replacement for beetroot shots

I used to take beetroot shots but they always played havoc with my eco system, my coach spotted these on an advert so thought I’d give them a crack.
I’ve only been them before hard sessions and races like I would’ve the shots. While I’m not 100% convinced of their efficacy I’ve had some great performances and will continue to use them.

Thanks for your review! 🙌
Great to hear they’re working well for your hard sessions and races – glad you’re getting strong performances and enjoying them as a beetroot shot alternative! 💪

Why would I need to take 3 capsules on rest days?

Why would I need to take 3 capsules on rest days? Can’t I just take 3 capsules before my exercise?

Thanks so much for your question! 😊 We recommend taking 3 capsules even on rest days to help maintain steady nitrate levels in your body. Consistent intake keeps nitric oxide availability high, supporting blood flow, oxygen efficiency, and even recovery between training sessions.
If you only take them before workouts, you might not get the full performance benefits that build up over time. Still, you can adjust your routine based on your training schedule — feel free to reach out at info@4endurance.co.uk if you’d like help finding what works best for you! 💪
