Continue reading to find out if this product offers the best value for money of all the coenzyme Q10 supplements available on the market.


The active ingredient in the supplement is coenzyme Q10. Coenzyme Q10 is a powerful antioxidant substance which removes the toxic metabolites of normal cell functioning. If these metabolites, known as free radicals are not removed, they cause tissue damage and inflammation which can lead to premature aging and even cancer.

The enzyme Q10 is also very important for energy production in every single cell in the human body. Coenzyme Q10 forms part of a very complex network of molecules which shuttle energy in the mitochondrial membrane during the third phase of cellular respiration (known as oxidative phosphorylation) to produce ATP which the cell later uses as a source of energy. Up to 95% of cell energy is produced this way.


The daily dose of this supplement is one capsule. For the best absorption, it should be taken with food. Each capsule contains 300 mg of coenzyme Q10.

Possible Side Effects

There are no listed side effects, however it is not advised for pregnant and nursing mothers to use this product. If you are using blood thinning medications be sure to consult your physician before using this product  The capsules are also made using gelatin so this product would be unsuitable for vegetarians and vegans.


One bottle of StemLabs CoQ-10 capsules contains 30 softgel capsules which can be bought online for around $33.00. No discounts are offered for buying in bulk which makes the long-term use of this product more difficult and expensive.


The manufacturer does not offer a guarantee on this product.  In fact they explicitly state that all products bought from them are strictly non-returnable, non-refundable and non-exchangeable. We strongly believe this reflects badly on the manufacturer’s view of their own product. If they are unable to provide a guarantee, they are not certain that it will provide the results that they claim it does.

Our StemLabs CoQ10 Review – Conclusion

As far as coenzyme Q10 supplements are concerned, this one is pretty standard. It offers the pure extract of coenzyme Q10 without any supporting ingredients. Although this delivers pure ingredients, some substances may be necessary to improve the effects such as enhancing the absorption of coenzyme Q10. The price is similar to many of this product’s competitors too.

We don’t find anything to particularly stand out about this product that would rank it above similar products. Conversely, there are some products on the market which do stand out because they contain the supporting ingredients as well as a guarantee on their product.
