Douglas Labs’ Corvalen® Ribose Chewable Tablets may be a quick and convenient way of providing D-Ribose sugar in your diet. These tablets are sweetened with xylitol and have a natural orange/vanilla flavoring.

D-ribose is a natural sugar that may be able to support circulatory health‚ energy production‚ and mitochondrial function. In many ways‚ our bodies can utilize D-Ribose as a form of metabolic fuel. It is a carbohydrate and takes part in the production of adenosine triphosphate (ATP). ATP works as a direct source of energy for cells and needs to be maintained for healthy functioning.

Douglas Labs’ Corvalen® Ribose Chewable Tablets provide 1.67 grams of bioavailable D-Ribose in each serving. They may be taken once to three times daily or as directed by your healthcare practitioner.

Although ribose is created in our bodies‚ times of high stress and poor nutrition may decrease the levels available for our cells. That’s why a supplement like Douglas Labs’ Corvalen® Ribose Chewable Tablets could be able to help us maintain heathy D-Ribose levels.

      I have been using this product for many years for heart health and discovered it has almost eliminated my atrial fib episodes. I was having, on average, an episode a month. I now only have about three episodes a year.

      Pros

      It has reduced my atrial fib episodes.

      Cons

      It's pricey; I used to get it for 38.00 from a different source, who is no longer available. It is hard to find a source anymore. May be the reason for the price increase.

      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.
