This was the first CoQ10 I tried. I bought the trial size after reading about how it was used in trials for controlling migraines. I was amazed that after only a few days of taking 100 mg twice a day I felt so much more alert and not tired like I normally am. I used to feel like I was in a haze all day but especially in the evening, and I could barely stay awake after about 9:00 PM. While I was taking this CoQ10, I was pleasantly surprised that I had none of that brain fog and was shocked to be awake, alert, and not at all fatigued even at 10:00 PM! I was still able to sleep just fine at night, but I didn't have the bone-deep weariness throughout the day. It was almost a side benefit that my daily headaches were gone too! Since this was my first try at CoQ10, I tried another brand, but while I found I had some relief and some of the tiredness was gone, I didn't have quite the same results as with the California Gold Nutrition CoQ10. I was getting some headaches a few times a week and felt just somewhat less tired than without it. I did a little research, and it turns out that the highly-touted ubiquinol form is actually unstable and by the time it reaches the shelf, most of its benefit is gone. This form (ubiquinone) is stable, and the body can and does turn it into ubiquinol as needed and back if needed. No wonder I had better results with California Gold! I've learned my lesson, and I am never going to stray again.

Not a fan of the additional ingredients, especially the safflower oil which is typically used in overly processed and low quality foods/supplements.

If you have digestion or dysbiosis problems, or SIBO or other sensitivities, you don't want to take this CoQ10.

I have received several supplements by this brand cheap or free which tells me that is probably how much they are worth. This particular product contains carrageenan which is an undesirable additive even found in some organic foods that is known to cause cancer.

It caused a lot of inflammation. It was painful.
