In the review below, the product CoQ10 100 mg, by the manufacturer Cooper Completed, will be investigated. The manufacturers claim that the goal of this dietary supplement is to support healthy heart function, help to maintain a healthy cholesterol level, and reduce muscle pain. The product also helps with natural energy levels and neurological health. The company claims that their main ingredient, Ubiquinol, is a more bioavailable form of Coenzyme Q10 than the common Ubiquinone form. Although Ubiqinone is converted to Ubiquinol naturally, as one ages, this process becomes less effective.


The active ingredient in the formula used by this product is Ubiquinol (a reduced form of CoQ10, 100 mg). Ubiquinol is a more bioavailable from of CoQ10, allowing for a better uptake of this substance. CoQ10 is an antioxidant found in every cell in the body. It acts as a catalyst, converting food into energy. Although this formula makes use of a more bioavailable form of CoQ10, it is only necessary to consider absorption of this substance after the age of 40 when absorption slows down. However, Coenzyme products, based on the point of absorption, can still be effective, particularly when piperine is added.

Other ingredients include olive oil, gelatin, glycerin, ascorbyl palmate, water, yellow beeswax, sunflower lecithin, and carob extract.


The manufacturer suggests taking one capsule daily, or as instructed by a doctor. Otherwise, the dosage instructions are unclear. There is no mention of best time to take the capsule, or whether to do so with food or liquid. Our research also found a problem with this maker’s supplier, in that the capsules are not always a standard size. The capsules may, at times, be too large to swallow easily.

Possible Side Effects

The manufacturers of this product state that it is free from yeast, gluten, dairy, corn, sodium, sugar, starch, artificial coloring, preservatives and flavoring. This means that people with food allergies will be able to take this supplement. However, as this product contains gelatin, it is not suitable for vegans or vegetarians. There is a warning from the manufacturers that pregnant women, and nursing mothers, or anyone on prescription medication, should first consult a doctor before taking this supplement.


CoQ10 100 mg is available online, directly from the makers of the product, Cooper Complete, at $35.98 for 30 soft-gel capsules. There are no discounts available on this product, but a locked-in option of a subscription is offered.


The manufacturer does provide a 100% satisfaction guarantee. You may thus return the product for a full refund. It is optional whether to provide a reason for the return − there is no obligation to do so. In terms of the return policy, there is a three weeks’ waiting period before the refund check will arrive. Of greater concern, is that, despite our search, we were unable to find a clear cut-off date for returns to be made. It is therefore best to contact the manufacturer before buying the product, checking on the expiry date for possible return of the product.

Our CoQ10 100 mg Review – Conclusion

CoQ10 100 mg is a worthwhile dietary supplement, supported by a 100% money back guarantee, even though some details of the return policy are lacking. However, the company does allow a free trial of this product. In addition, ordering this product is easy − you may do so online, on their website. However, be careful of being locked into a subscription. You may not like the product, or only realize after you have ordered it, for instance, that it contains gelatin. If you are vegan, you have to wait for up to three weeks to receive your refund. It is also regrettable that the manufacturers do not offer a discount on bulk sales, thereby saving you money in the long term.
