Hi,
Everyone has a budget. Sometimes that's the overriding consideration. In terms of supplements or any processed food products that you put in your mouth, they should have been reviewed by a testing authority to ensure that they were manufactured using good laboratory practice. In other words- you get what you pay for and it is not tainted. The trouble is the world doesn't quite work that way. When I looked through the website I couldn't work out anything about how they were manufactured at all. Walk into a naturopath, health food shop, chemist etc and look at the brands behind the counter. If you have trouble walking perhaps ask someone to look for you.
In terms of the CoQ10, it should be in a soft gel capsule with d-alpha tocopherol. Like this one, where you can see the ingredients

My preference is not so much about brand but rather that the product is as good a standard as you can get. That also means its packaged and stored correctly. I don't buy my supplements from the internet because I can't feel confident that what the label says is necessarily supported by good laboratory practice, good handling and good storage. As a result, I prefer the brands that the better health providers would use and generally you have to ask at the counter for them.
There are a lot of products on the market, as it is hyper competitive, but only some are practitioner brands. I'd rather stay with those.
You can, of course, try the ones you pointed out. The risk is they are no better than lollies. I've had that experience.
Regards,
