Possible Side Effects

Douglas Laboratories notes in the supplement information that there are no adverse side effects associated with this product, however, research shows that taking 300 mg of Coenzyme Q10 may cause possible side effects such as rashes, nausea, abdominal pain, dizziness, sensitivity to light, irritability, headaches, heartburn, and fatigue. This product is not suitable for children and while it may contain no yeast, wheat gluten, milk/dairy, corn, sodium or starch, it does contain soy which may cause allergic reactions for some.

Our Douglas Laboratories Ultra Coenzyme Q10 Review – Conclusion

There are a few aspects of this brand that suggest that this could be a potentially good supplement to promote a healthy heart. The manufacturer provides clear information on the website about the money back guarantee and the benefits of Coenzyme Q10 however, we are concerned about the possible side effects and allergic reactions from the dosage and soy. The formula also contains a variety of fillers and binders which may compromise the quality and potency of the Coenzyme Q10. We failed to find a sufficient amount of reviews from trustworthy sources to provide social proof about the effectiveness of this product which suggests that it is not well known or popular. For consumers who are looking for a product that has enough social proof and contains Coenzyme Q10 without the binders and fillers, it may be in your best interest to look at alternative brands.
