Fatigue reducing agent
View Patent ↗To maintain physical fitness and health of middle-aged and older persons living in the threshold of the aging society, the present invention provides a fatigue reducing agent which is highly effective for preventing and reducing fatigue, wherein the agent is made of a composition of substances that are very safe so that long-term administration is possible. A composition containing reduced coenzyme Q was found to be effective for preventing and reducing fatigue, including muscle fatigue. Since the fatigue reducing effect of the composition of the present invention is seen not only in young rats but also more pronounced in aged rats, the present invention can provide the fatigue reducing agent which is very useful, especially, for middle-aged and older persons as well as for young people.
1. A method for reducing fatigue in animals in the state of fatigue, wherein the animals are middle aged or older persons and wherein the fatigue is physical exhaustion, which comprises administering, to said animals, a fatigue reducing agent in a therapeutically effective amount comprising, as an active ingredient
reduced coenzyme Q represented by the following formula (1) (wherein n represents 10)
and oxidized coenzyme Q represented by the following formula (2) (wherein n represents 10)
wherein a ratio of reduced coenzyme Q to total coenzyme Q is not less than 99% by weight, or
reduced coenzyme Q represented by the above formula (1) (wherein n represents 10) in an amount of 100% based on total coenzyme Q.
2. The method according to claim 1 , wherein the fatigue reducing agent is administered orally.
3. The method according to claim 1 , wherein the active ingredient is reduced coenzyme Q and oxidized coenzyme Q and the ratio of reduced coenzyme Q to total coenzyme Q is 99% by weight.
4. The method according to claim 1 , wherein the active ingredient is reduced coenzyme Q and oxidized coenzyme Q and the ratio of reduced coenzyme Q to total coenzyme Q is 99 to 99.5% by weight.
