Cannot feel the effect

Posted by RubiesHealth on January 15 2013 | Verified Purchase

I have tested many CoQ10 formula - ubiquinol, ubiquinone (Kaneka certified), oil-based in softgel, powder form in capsule, hydro-soluble form that is recommended by cardiologist Dr Sinatra, and more. This formula seems to contain the right ingredient to enhance absorption - olive oil as a carrier, lecithin as an emulsifier, and pepper which is known to aid absorption. But I do not feel the effect in sports, even after taking twice or 3 times daily. Don't take CoQ10 simply for peace of mind. It is not like supplements that work "quietly", like calcium, until you do a scan or blood test. You can and you must feel the difference with CoQ10. Test the effect by doing something physically strenuous, like climbing stairs for old-folks, or doing your regular sport. There are many brands on iherb (despite lower ratings) that are more effective. Jarrow A-Absorb series and Country Life hydrosoluble softgel are examples.

Thanks for your feedback!

Great product, but soft gels not good

Posted by VicWong on November 2 2017 | Verified Purchase

The CoQ10 is great, please purchase the capsules. The soft gels have discoloration as some gels are off colored. The product gets stuck to each other and I had difficulty separating them. If too much force is used, the gels will break and the products will come out.

Thanks for your feedback!

Gives me stomach upset

Posted by iHerb Customer on May 11 2015 | Verified Purchase

I tried 100mg Jarrows ubiquinol daily and 200mg (2 caps) of this product daily. The ubiquinol gave me a obvious boost in energy but this product only gave me stomach upset even when I took this after meal. Not repurchasing this product, as it doesn't suit my body. Please do not take this on empty stomach, as it has black pepper in it.

Thanks for your feedback!

I've heard of Doctor's Best products before and decided to try it, since the price was good. Not sure (as of yet) if it works as well as the Ubiquinol/Ubiqinone formulation. Need more time.

Thanks for your feedback!

I am using this product in combination with red rice yeast. Suddenly I got a mild form of hives but I am unsure whether this supplement is the cause. After 2 weeks the hives disappeared however.
