What is Quercetin?
Quercetin is a natural flavonoid found in fruits, vegetables and plants such as apples, onions or red wine.
It is known for its antioxidant properties that can help protect cells from oxidative stress.
Studies suggest that it may contribute to normal immune system function and blood vessel health, but its effects are not officially confirmed.
Although it is possible to obtain Quercetin from food, the most effective form is a highly concentrated extract in capsules or powder.

How does Quercetin work?
Quercetin acts as a powerful antioxidant that neutralizes free radicals - unstable molecules that can damage cells.
This antioxidant activity may contribute to normal cardiovascular function and cell protection.
It is also involved in the regulation of inflammatory reactions and may contribute to the normal response of the immune system to environmental stimuli.
Studies also suggest its possible effect on stabilizing histamine-releasing cells, an important factor in allergic reactions.

Biohacking: science, technology and the path to a better self
Biohacking is an approach to optimizing the body and mind through science, technology and lifestyle changes. The aim is to improve performance, health and longevity through methods such as diet and sleep modification, supplementation, meditation, breathing exercises or the use of modern technology such as biomarker monitoring. Biohacking often draws on principles from nutritional science, neuroscience and epigenetics and combines them with practical tools to help people function better, feel more energetic and slow the aging process.
Roots of biohacking dates back to the 1990s, when the first experiments with personalised nutrition and health tracking technologies began to emerge. In 2005, Dave Asprey, founder of the Bulletproof Coffeewho combined nutrition, supplementation and technological innovation to improve mental and physical performance. Biohacking today is divided into several directions - from nutritional biohacking to neurohacking to hardcore biohacking, which includes implants and genetic modification. Overall, it is a conscious approach to health that uses both traditional methods and the latest scientific knowledge.
In our shop you will find other companies that have dedicated their research to this. It is, for example, a Dutch company NoordCode which specialises in functional foods and supplements for the 21st century. Their products are designed to promote a clean and wholesome diet, reduce inflammation and provide healthy and delicious options for everyday living.
Another important company is the American company Jigsaw Healthfounded in 2005 by Pat Sullivan. Specializes in the manufacture and sale of dietary supplements aimed at promoting health and vitality, including vitamins, minerals and probiotics.
Last but not least, there is Bioptimazerswho focus on optimizing health and performance through high quality nutritional supplements. Their products are designed to support various aspects of health, including digestion, sleep and cognitive function.
