Today we review Nutra-Life CoQ10 300 mg.  Coenzyme Q10 has been shown to help lower blood pressure, improve overall heart health, and keep your immune system healthy.  This high dose supplement is a once per day formula that helps to support your overall cardiovascular health.


  • Ubidecarenone (Coenzyme Q10)
  • Encapsulating aids
  • Color

While the name of the supplement includes the amount of 300 mg, the website has stated two different amounts of CoQ10 in their supplements.  On one part of the website, it does state each capsule contains the advertised 300 mg, while another part of the site only reports 150 mg per capsule.  This is worrisome for two reasons.  First off, if the manufacturer does not consistently advertise the correct dose, we are unable to know how effective this product will be.  Also, in our extensive research, we found the highest dose of CoQ10 should be between 200-250 mg.  That makes these capsules, depending on their real dosage, either too low or too high in the amount of CoQ10 that they contain.


The manufacturer recommends taking one capsule per day, with food.  Again, without knowing exactly how much CoQ10 is in each capsule, we are unable to correctly evaluate if this dose is effective or not.

Possible Side Effects

While the manufacturer did not list any possible side effects, through our research, we learned that CoQ10 supplements can cause many stomach issues, including pain, nausea, or diarrhea.  This supplement also contains artificial colors, which can be problematic for some diets.  Also, people who take Warfarin should avoid taking this supplement.  If you experience any side effects, you should consult with your healthcare physician before you continue this supplement.


Instead of buying this product direct from the manufacturer, customers are sent to a third party seller.  This seller has the Manufacturer Suggested Retail Price for a 60-count bottle listed at $52.99, but it is currently for sale at only $29.99.  While the purchase price of this supplement is less expensive than others we have seen, because the third party is an Australian company, shipping to the US costs an additional $29.95, making this a very expensive purchase price overall.


Neither the manufacturer nor the third party seller offers a guarantee on this product.  The third party seller also does not accept the return of medications or supplements.  If you decide to purchase this product and are unhappy, you will be unable to receive a refund for the purchase price of this supplement.

Our Nutra-Life CoQ10 300 mg Review – Conclusion

There are a few things we liked about Nutra-Life CoQ10 300 mg.  First off, the initial purchase price of this product is less expensive than other supplements we have seen.  Also, the supplement does have a simple ingredient list.

Unfortunately, we have many concerns about this product.  The manufacturer’s website was unclear about the true dosage of this product, so we are unable to know the effectiveness of this supplement.  There are also quite a few possible side effects we found in our research.  Lastly, because the manufacturer sends you to a third party to purchase this product, shipping becomes very expensive and there is no guarantee on this product.  For these reasons, we cannot recommend this supplement.
