Ingredients Label
Active Ingredients
Citrulline
Citrulline is an amino acid that increases levels of nitric oxide in the body.
Nitric oxide is responsible for vasodilation, a widening of the blood vessels which improves blood flow, pumps, and endurance (1).
Arginine
Arginine is very similar to citrulline, and also boosts nitric oxide.
The formula contains three different forms of the compound, which all have similar effects (2, 3).
Arginine nitrate is possibly the most interesting one due to the “nitrate” part of the molecule. Nitrates also boost nitric oxide, and are found in nature in beetroot and other vegetables (4).
Grape Seed Extract
Grape seed contains compounds with antioxidant and potentially anti-oestrogenic effects (5, 6).
Resveratrol
Resveratrol is a compound found in grapes which improves heart health and insulin sensitivity.
Unfortunately, it also may counteract the positive effects of physical exercise (7).
Who Takes It?
Athletes wanting to improve pumps and endurance during their workouts may benefit from using NO3 Ultimate.
How to Take
Mix 1 scoop (10.5g) with 250mL water, and consume 30 minutes before working out.
Side Effects
Nitric oxide boosters may temporarily reduce blood pressure due to a dilation of the blood vessels.
May upset the stomach if taken without sufficient food or water.
Pros
- Multiple forms of nitric-oxide boosters included
- Stimulant free
- Antioxidants added.
Cons
- Doesn’t improve pumps through any other mechanisms
- Resveratrol may be counterproductive to progress.
Conclusion
NO3 Ultimate is a stimulant-free nitric oxide booster which should do well to improve pumps and endurance in the gym.
Although it contains highly effective doses of its ingredients, it only focuses on a single aspect of pump enhancement, which may be a missed opportunity.
It’s stimulant-free, which makes it easy to combine with other pre-workout products which contain caffeine.
