Why active men look at nitric oxide

During exercise, working muscles need more blood, oxygen and fuel. Nitric oxide is one of the signals that helps blood vessels open up to meet that demand. That's why nitrate-rich beetroot products are popular with runners, cyclists and gym-goers.

What the research on ingredients says

Studies of beetroot juice and dietary nitrate have looked at endurance and efficiency during exercise. Results vary between people and are generally modest, and effects in well-trained athletes tend to be smaller. Research on L-arginine for performance is mixed. No study has tested Nitric Boost Ultra itself, so treat it as a supportive part of your routine, not a performance guarantee.

Fitting it around training

• The seller's directions are one scoop a day. There is no special pre-workout dose.
• Many people take their daily scoop a couple of hours before training. Others keep it at breakfast for consistency.
• It contains no stimulants (seller-stated), so it can sit alongside your usual coffee. Keep an eye on how you feel.

The training basics come first

Progressive strength training, sensible cardio, enough protein and rest days drive performance far more than any supplement. Our energy and stamina page covers the recovery side.
