Glucose and the Endurance athlete — 6 Comments

      • I’ve tried so many things on long runs that it’s fascinating to me, too. But I’ve never tried glucose tablets. I’d like to see the “nutrition label” for them, but it’s hard to imagine that they are much different from some of the other options. I’ve been using a maltodextrin powder mixed with water, and I’ve been happy with the results from that.

        • Each tablet is 4 grams, and it’s 4g of sugar. The ingredients are: Dextrose (d-glucose), cellulose, citric acid, magnesium stearate, natural and artificial raspberry flavor, ascorbic acid, FD&C red #40. It’s almost like candy.
          As you can see, a 4g tablet had 4g of glucose in it, so those other ingredients are trace amounts. Just enough to give it some color and a tangy flavor.
          One of my friends mentioned using them, so I thought I’d give them a try. It’s hard to say they are better than anything else until I try them a few more times.
          Unlike gels, these tablets are only sugar. That could be a problem during a marathon.

  1. Funny, as a Type 1 diabetic runner, I usually run with glucose tablets on hand. I wouldn’t have thought to recommend them for others but it makes sense.

    • Hi Adrienne,
      I’ve only used them once. They are really for an emergency, you know, hitting the wall really bad!

      The pharmacist did give me a funny look when we were talking about them. They are not candy.
