What makes Sanazia Cordyceps CS-4 special?
Cordyceps sinensis is an adaptogenic fungus that has been used for centuries in traditional Chinese medicine to support energy, vitality and lung function. Its main mechanism of action is supporting the production of ATP (adenosine triphosphate), the basic energy molecule in the body, thereby contributing to more efficient oxygen use and increased cellular energy. Thanks to its content of active compounds such as adenosine and polysaccharides, Cordyceps supports aerobic capacity, delays the onset of fatigue and helps you cope better with physical and psychological strain.
Sanazia Cordyceps CS-4 contains a patented, clinically tested strain of Cordyceps sinensis, considered the gold standard thanks to its consistent quality and potency. Unlike wild cordyceps, which is rare and expensive, CS-4 is grown by a sustainable fermentation process and standardised for a precise adenosine content. The dose of 500 mg per capsule represents an optimal amount for everyday support of energy and performance, while being well tolerated and suitable for long-term use.
Our Cordyceps CS-4 is produced by controlled fermentation of mycelium in a sterile environment, which guarantees maximum purity and the absence of environmental contaminants. This modern process makes it possible to preserve a high content of bioactive compounds responsible for its beneficial effects. Every batch of extract is strictly tested in independent laboratories to confirm adenosine content, microbiological purity and the absence of heavy metals, guaranteeing premium, safe quality.
The efficacy of the CS-4 strain has been confirmed by several clinical studies. For example, a double-blind, placebo-controlled study by Chen et al. (2010) showed that 12 weeks of taking Cordyceps CS-4 (at a dose of 1000 mg daily) in healthy older adults led to a significant 10.5% increase in the metabolic threshold, meaning improved endurance and a delayed onset of fatigue during physical activity. These results confirm its reputation as an effective aid for supporting physical performance.
Improving energy metabolism and aerobic capacity is a gradual process. The first subjective feelings of increased energy and reduced fatigue may appear after a few weeks, but to achieve measurable changes in performance, regular use for at least 12 weeks is recommended. Cordyceps CS-4 is not a stimulant with an immediate effect, but rather an adaptogen that supports the body's resilience over the long term. The best results are achieved in combination with regular physical activity and a healthy lifestyle.
