Douglas Labs’ Corvalen® D-Ribose delivers pure D-ribose to help your body make more energy‚ and who doesn’t want that? This effective nutritional supplement is comprised of a natural pentose sugar; this ingredient has been designed to provide strong support for cardiovascular health‚ energy production‚ relieving fatigue‚ and optimal functioning of the mitochondria. The slightly sweet D-ribose powder tastes great‚ dissolves quickly‚ and releases its nutrients quickly; this allows your body to benefit far sooner.

It’s just a fact that each and every cell in the human body requires significant amounts of energy in order to continue to function at peak levels. Without adequate sources of the necessary energy‚ every system within your body will slow down—and may eventually fail. Corvalen® D-Ribose is a must-have supplement for good health not only due to its ability to provide the needed food for cells‚ but also because it works to maintain efficient energy production.

Corvalen® features ribose in its pure form. Ribose is the most fundamental building block of adenosine triphosphate (ATP)‚ the primary source of energy for every muscle cell in your body; aging‚ strenuous exercise‚ overexertion and other conditions can drain ATP from your tissue and affect how well your body makes and uses energy. This naturally safe substance has been the subject of extensive clinical study that has revealed its ability to enhance the body’s natural process of energy production.

Taking Corvalen® every day promotes the quick restoration of this lost energy while relieving muscle stiffness‚ soreness and fatigue. In addition‚ this powerful supplement may also:


  • Promote healthy muscle and heart activity

  • Improve athletic performance

  • Speed up muscle recovery


Life in the modern world can certainly take its toll on your health. Corvalen® D-Ribose provides 9.9 ounces (or 280 grams) to energize the heart and other muscles by increasing energy at the cellular level.

      Taste is awful. Corvalen Ribose by Douglas Laboratories tastes like soap and made me sick to my stomach. I have used the powder for a long time and ordered this for travel based on the reviews. Also, if I am reading this correctly, it has less grams per serving of the D-Ribose than the powder.

      Pros

      Nothing

      Cons

      Tastes like soap and made me sick

      Corvalen Ribose by Douglas Laboratories helps with digestion and decreases my appetite. It was recommended by a functional medicine physician. I put it in my protein shakes daily. I can feel a difference in energy and well being if I don't have my morning shake.

      Pros

      Nice natural flavor.

      Cons

      Expensive.
      I would recommend this item to a friend.

Customer Questions and Answers

1-1 of 1

  • Question:
    Corvalen seemed to work well for me and then I bought Sedona because it was almost $20.00 cheaper. I'm not sure if it works as well. Sedona says it was "formerly Corvalen". I'm not sure what that means. What is in Corvalen that isn't in Sedona?
    Kathleen on 9/26/2014 Answer:
    • Hello, thank you for contacting PureFormulas. I recommend you to contact Sedona Labs directly.
