Coenzyme Q10 (CoQ10) is one of the most intensively studied cardio-protective nutrients, which can also increase overall energy and act as a powerful antioxidant against free radicals.*

Because standard CoQ10 is poorly absorbed, a number of technologies have been developed to improve its bioavailability. Unfortunately, while these products may dramatically increase CoQ10 absorption in some people, they have little or no effect in others.

CoQ10-SR® is different. Delivering sustained release over 24 hours, CoQ10-SR contains MicroActive® CoQ10, the only form of CoQ10 shown in human clinical studies to have universal enhanced absorption across all subjects.* In fact, CoQ10-SR:

  • Doubles CoQ10 levels from baseline in 3 weeks*
  • Delivers sustained release over 24 hours*
  • Is 3x better absorbed than regular CoQ10*
  • Is 2x better absorbed than solubilized (“enhanced bioavailability”) CoQ10 softgels*

Coenzyme Q10

Coenzyme Q10 (CoQ10) is a vitamin-like substance present in virtually every cell of the human body. It aids in energy production, so it is most common in organs with high energy requirements such as the heart, liver, and kidneys.* Research has shown CoQ10 helps maintain blood pressure levels already within a healthy range.* MicroActive® CoQ10 is three times better absorbed than regular CoQ10 and two times better absorbed than solubilized (“enhanced bioavailability”) CoQ10 softgels.

Q: How long does the CoQ10 stay in your system?

A: The MicroActive CoQ10 in our CoQ10-SR formula has been shown to offer 24 hours of sustained release and offers 3.7x greater bioavailability than regular CoQ10.

Q: Is the CoQ10 derived from natural sources or is it synthetic?

A: The MicroActive CoQ10 used in our CoQ10-SR products is not a synthetic material. MicroActive CoQ10 is derived naturally via a fermentation method using microorganisms.

Q: What is the maximum amount of CoQ10-SR a person can take?

A: The daily dosage is 100 mg because it is 3x more absorbed by the body making it the equivalent of taking 300 mg of regular CoQ10. We do not recommend taking a dosage that exceeds more than 400 mg (4 capsules a day). If you consume too much CoQ10, it will simply pass through your body. Therefore, there are no benefits to taking a higher dosage than what is recommended.

Q: Is it possible for the polymers in the formula to bio accumulate over time?

A: The polymers like HPMC are not absorbed by the system. HPMC is a soluble fiber that is also not fermentable by the colon bacteria. Beta cyclodextrin  is also not absorbed from the stomach and small intestines. It can be broken down by the enzyme amylase to form open chain sugars and glucose. Carnuaba wax is highly insoluble and is not absorbed. So, all the polymers are eliminated from the GI tract, no chance of bioaccumulation.

Quality of Life is there when you need them

I don't understand how it is possible to write a review for a product that takes a long time to show results, but since I trust Quality of Life I bought the CoQ10-SR for my wife, who is taking statins, and certainly needs the time-release product. I think these pills are a reasonable size and the proper potency. As usual, Quality of Life was there when I conceived of the need.
