I purchased this product after researching the benefits of natural supplements that may help chronic fatigue. I specifically liked that CoQ10 helped boost energy levels, which is what I need the most. I’ve used this product daily for about 3-4 months now and found it of benefit, particularly during the first half of the day, as I take it in the morning. I don’t feel as much of a boost towards the later part of the day, but overall I’ve found I still have more energy in general than I used to, in combination with making other lifestyle changes (pacing, de-stressing etc). Would definitely recommend this product for others to trial.
