This review is for a product called Zenith Nutrition CoQ10 Plus, one of many dietary supplements for heart health available on the market. The manufacturer claims that this product is an advanced form of Coenzyme  Q10 (CoQ10) because it includes vitamin E, which provides greater antioxidant support and protection to the heart. CoQ10 helps with the production of cellular energy in organs such as the heart.. The manufacturer claims that supplementing the body with CoQ10 daily helps maintain healthy cholesterol and blood pressure levels, which contributes to the overall heart health.


  • Vitamin E
  • Coenzyme Q10 (Ubiquinone) (Naturally fermented)

Coenzyme Q10 is known for its strength to increase energy production in the heart and other vital organs in the body. Vitamin E however has been proven to have no benefit at all to the heart health. Recent research indicates that there is a potential that Vitamin E might be harmful than beneficial to the heart. We are concerned that Vitamin E has been included in Zenith Nutrition CoQ10 Plus because it might alter the effectiveness of CoQ10 in it.

Other ingredients: Dicalcium Phosphate and Vegetarian capsules.


The recommended dosage is one capsule taken daily or as directed by your healthcare professional. It is not indicated whether you take it with or without food.

Possible Side Effects

Possible side effects for CoQ10 include diarrhea, loss of appetite, vomiting nausea, skin rashes and upset stomach.  It is also known to lower blood pressure, which could be a problem if you already have a low blood pressure.


Zenith Nutrition CoQ10 Plus is available online from various retailers and from the manufacturer’s website. The price is $19.53 for 60 capsules, $36.90 for 120 capsules and $37.84 for 240 capsules in a bottle. Some retailers sell the product in bulks, but you need to send an email indicating that you want to buy in bulks. Discounts are available at selected retailers. We noticed that the product is out of stock from some retailers. This may seem as a good thing because it could mean that people are buying it, however it is a problem when you run out of your supplements and you need more and you can’t find them because they are out of stock.


The manufacturer states clearly that there is no guarantee that this supplement will be effective on you, as results depend on each individual and other factors.  Returns are only accepted if there is something wrong with the product. If that is the case, you need to inform them within 24 hours of receiving the product. The product should be unused and should be sent back with the original box.

Our Zenith Nutrition CoQ10 Plus Review – Conclusion

Zenith Nutrition CoQ10 has a potential to be effective, considering that CoQ10 is a well-known supplement that supports heart health. Its price is reasonable and you are able to buy it in bulks if you want to. We are concerned that Vitamin E is included because recent research indicates that it provides no benefit to the heart. The manufacturer also clearly states on their website that they do not guarantee that this supplement will work for you. Considering the inclusion of Vitamin E, the lack of guarantee and possible side effects, buying this product is a risk. Rather look for a product that does not have Vitamin E and one that is backed by a money-back guarantee in case you need to return it.
