What is Dr David Williams CoQ10?

This review if for a product called Dr David Williams CoQ10, a dietary supplement that is designed to help support cardiovascular health and provide energy to your body cells. It also promotes stamina, maintains normal blood pressure levels and supports the immune system. The manufacturer claims that their product is manufactured to exacting standards using great quality of raw materials. They ensure that every batch is tested to verify its purity. Moreover, the manufacturer encourages everyone over the age of 40 to take CoQ10 supplement because the body’s natural CoQ10 decreases with age.


Ubiquinone, which is an oxidised form of CoQ10 has been used as the main ingredient of Dr David William’s CoQ10. This form of CoQ10 works much quicker that the oxidised form, Ubiquinol because it has already gone through the state of oxidation.

CoQ10 is a strong antioxidant that resides in the mitochondria of your cells and plays an important role in the production of cellular energy in your body. The body organ that contains the most concentrated CoQ10 is your heart, which is why this enzyme is considered to have an important function in your cardiovascular health.

Other ingredients: Stearic acid, silicon dioxide gelatin, beta cyclodextrin and microcrystalline cellulose.


The recommended dosage is 2 capsules daily. It is not stated whether you take it with meals or not. Since each capsule contains 200 mg, we are concerned that taking 2 capsules will be a bit too much. Even though there is no established dose on the CoQ10 supplement, the typical dose that has been used in studies and proved to be effective is 100mg to 200mg a day.


60 capsules of this supplement can be purchased from the manufacturer’s website at a cost of $54.99 per bottle. The price is the same from online retailers. The manufacturer offers you one bottle for free if you purchase three bottles. You get two at no charge if you purchase five bottles.

Possible Side Effects

Possible side effects associated with CoQ10 are vomiting, nausea, diarrhea, stomach discomfort and allergy reactions. People that are on medication, those that have high blood pressure, breastfeeding and pregnant women should consult with a healthcare professional before taking this supplement.

Manufacturer’s Commitment

The manufacturer offers a 100% satisfaction guarantee, and they promise to give your money back if you do not see results, or if you are unsatisfied for any reason. The money-back guarantee is 90 days.

Dr David Williams CoQ10 Review – The Bottom Line

Dr David Williams CoQ10 could possibly help support cardiovascular health and the immune system, providing the body with good overall health. It is good that the manufacturer shows their confidence in the product through a 100% satisfaction guarantee or your money back. However, we were very disappointed when we visited the review section on the manufacturer’s website, because there was only one review of the product. The customer indicated that they felt no difference, so they do not know whether or not it is working for them. That is really concerning considering that the dose is already high. This makes us think that the supplement is not strong enough. Moreover, even though the manufacturer gives you extra bottles when you buy three or more bottles, that is not helpful if you buy the product for the first time because there is no need to buy so many with your first try. Rather buy something affordable and one that is backed by positive customer reviews to be on the safe side.
