Researches at Uppsala University in Sweden gave mice CoQ10 for 4 weeks. Mice were made to perform swimming exercise with loads attached to their tails, corresponding to approximately 5% of their body weights, and the total swimming time until exhaustion was measured. Mice given CoQ10 took much longer to get tired. The researchers say, "These results suggest that CoQ10 supplementation improves swimming endurance and has an antifatigue effect."
     Comments: I have noticed that CoQ10 gives me more energy when taking a dose ranging from 30 to 60 mg. Sometimes if I take 100 or 200 mg I feel more energetic for a while but somehow it seems to be counterproductive later or the next day. Try for yourself to see what dosage works best for you. This nutrient is often sold at 30, 50, 60, 100 mg, and some companies even sell 200 and 300 mg per pills. See
Meat, fish, and nuts have a good CoQ10 content, while much lower levels are found in most dairy products, vegetables, fruits, and cereals. The average dietary intake is only 3 to 6 mg a day.
