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.

This is a good Co-Q10 product. I like that it does not contain Soy lecithin and is NON-GMO. I don't like that it contains carrageenan. Obviously, in one capsule there is very little in there but just be aware. If you have any intestinal issues I would avoid this product. I also don't care for the safflower oil or modified food starch but again there is very little in each capsule. CoQ10 is a very important supplement. I will not go into depth here as much has already been written on its benefits here and elsewhere. I will repeat that if you take a statin drug you would be well advised to supplement with this or the Ubiquinol form of Co Q10. I do prefer the Ubiquinol form which is the reduced form of Co-Q10 because it is much more usable. As we age we do not convert the Ubiquinone form of Co-Q10 to the Ubiquinol form very well. When we get into our 40's we do it less efficiently. As a result we need to take more of it to get the same effect. To get around this all you need to do is take the Ubiquinol form. It costs more but if you are effectively using almost all of it vs. 25% of the Ubiquinone form of CoQ10, is it really more expensive? One Study on older people has shown that 400mg of Ubiquinone is equivalent to 100mg of Ubiquinol. When this is on sale it is a very good deal. Go to my iHerb page and read which Ubiquinol products I like. If you found this review helpful can you kindly click the YES button. Peace and good health!

I took it because of low price for my father. It is not strongest, but moderate. My concerns are additional ingredients (too many) and especially modified food starch. These modifications nowadays make me sick, really.

Gave me a much needed energy boost but would not repurchase due to the carrageenan in it.

Did not notice any difference, perhaps i needed longer course than 30-day to see results.

Bought this because of the big saving ... the quality is average.

They are not strongest, but moderate. 100 mg not enough, but gives a little more energy than nothing. Easy to swallow, small size.I won't repeat, but, for 1$, not too bad.

No puedo opinar sobre la calidad porque aún no lo he probado.

haven't used these yet, but for the price decided to give them a try. I am a great believer of the benefits of coq10.
