✔ WHY NUTRAVITA'S COENZYME Q10? - Our high strength CoQ10 vegan capsules contain 200mg of 100% naturally fermented and easily absorbed Coenzyme Q-10 or Ubiquinone per capsule. Each bottle comes with 120 capsules of 200mg CoEnzyme Q10 for a four month supply.
✔ WHY TAKE COQ10 SUPPLEMENTS? - CoEnzyme Q10 occurs naturally in the body, and is present in every cell as an antioxidant. When free radicals outnumber antioxidants, it can lead to oxidative stress which could eventually damage our DNA and increase the risk of certain diseases. Several lifestyle and environmental factors can also contribute to excessive free radicals in the body hence maintaining the right balance of antioxidants is important.
✔ WHO CAN TAKE COENZYME Q10 CAPSULES? - In addition to being naturally fermented for bioavailability, our CoQ10 200mg supplement comes in easy to swallow capsules suitable for both vegans and vegetarians; are non-GMO and free from allergens such as gluten, soya, lactose, nuts and nut traces.
✔︎ QUALITY TESTED - Unlike many supplements, we haven't spared any expense on quality. Each ingredient is quality tested before the manufacturing process begins, every batch of our supplement undergoes further rigorous quality testing. We have done our best to provide as much information as possible, but if you do have any questions please reach out to our very helpful customer care team.
