Ive been taking this product for a 6 weeks. I feel a huge difference in energy level. I was not aware that the body can only handle 100 mg of ubiquinol at a time with the rest being peed out. If i had known i would have gotten the 100mg. Im using it to improve egg health in regards to fertility. I need 300 to 600 mg a day for my purpose. To get the best result i would have needed to take 1 pill 100 mg dose 6x a day about 90 mins apart. Theres no way to do that with a 200 mg pill. Regardless its a great energy booster. I feel amazing and it didnt take long. Be sure to take this in the morning. It does cause Insomnia if you take it at night because of the energy boost it gives. So take your last dose no later than 2 or 3 p
