What the scientific world says about ingredients

STEEL DURANCE is mainly a product dedicated to athletes of endurance sports, whose main goal is to maximize endurance and aerobic capacity. However, also those who practice sports with other characteristics can strongly improve their performance.

The main goal of STEEL DURANCE is to produce and utilize, as best as possible, nitric oxide, whose most well-known and remarkable function, in the context of sports physiology, is its role in controlling vasodilation. This leads to improved transport of blood, oxygen and a role in mitochondrial respiration, thereby enhancing training capacity and performance (1).

ARGININA

It is an amino acid that participates in the synthesis and bioavailability of nitric oxide (NO). As a result, it exhibits a vasodilatory effect, facilitating the flow of blood and thus oxygen and nutrients to working muscles (2,3).

CITRULINE

Citrulline is an amino acid that promotes nitric oxide (NO) synthesis. Thus, like arginine, it can contribute to vasodilation, improving blood flow and the delivery of oxygen and nutrients to working muscles. As a result, it can increase aerobic endurance and physical performance, which is particularly beneficial in endurance sports. Studies show that citrulline supplementation can increase ATP levels in muscles, resulting in better performance during prolonged and intense workouts (33).

RED SPINACH

It is a plant with high nutritional value that can provide numerous benefits to athletes. The plant is rich in numerous bioactive compounds, such as flavonoids and betalains, which exhibit antioxidant activity (34). Thanks to its high nitrate content, red spinach can improve blood flow and muscle oxygenation, which contributes to better physical performance. Nitrates are converted in the body to nitric oxide (NO), which dilates blood vessels, increasing the delivery of oxygen and nutrients to working muscles.

SLAVIA

Sage (Salvia officinalis L.) is a medicinal plant that has a number of properties that can support athletes. It contains numerous bioactive compounds, such as flavonoids, terpenoids and phenolic acids, which exhibit anti-inflammatory and antioxidant effects. Studies on athletes indicate that sage improves cognitive function (working memory, reaction time and less feeling of fatigue and exertion). The positive effects were obtained in the pre-exercise state and persisted even with fatigue (29). The action of improving memory and concentration occurs by inhibiting acetylcholinesterase, an enzyme that breaks down the neurotransmitter acetylcholine (30,31).
