Doppelherz aktiv Coenzyme Q10 Capsules contains Coenzyme Q10, vitamins B1, B6 and B12. This combination together may contribute to reduce fatigue by enabling the energy-yielding metabolism to work properly and supply all the muscles, including the heart, with enough power. Physical strain considerably increases nutrients needs. Especially as we age, even a balanced and varied diet might not be able to fully cover these needs. Coenzyme Q10, also known as �ubiquinone�, is a compound that is found practically in every single cell of our organism. Highest Coenzyme Q10 concentrations are found in the heart, the kidneys, the liver as well as the muscles. Around 45% of this Coenzyme Q10 is stored in mitochondria, the cell�s power plants, where it plays a decisive role in the production of cellular energy and muscular power. The heart in particular relies on a sufficient Coenzyme Q10 supply to work properly. Coenzyme Q10 can be synthesized by our organism and be taken up from Coenzyme Q10-rich food such as meats, vegetable oils and nuts. Under certain circumstances like when the organism is chronically exposed to pollution, during prolonged periods of physical or mental strain, when adhering to an unhealthy way of life, while aging etc, the body�s ability to make Coenzyme Q10 decreases. In these times, a sufficient dietary intake of Coenzyme Q10 is necessary to respond to the energy demand of the muscles and of the heart. Hawthorn is well known and commonly used in Europe to strengthen the heart and increase exercise tolerance in the elderly. Hawthorn fruits powder contains flavonoids which show a positive effect on blood vessels.
