Sodium bicarbonate has long been used to help professional athletes eke out an extra percentage point in their performances, but bicarb spells trouble for most GI systems. Has Maurten cracked the code?

Cycling Weekly Verdict

The Maurten Bicarb System is a pricey addition to one’s nutrition plan for little measurable benefit and the potential drawback of major digestive upset. Due to the inexact performance benefit it provides, it can be difficult to tell if the product is working for the individual. The texture is highly unpleasant to consume and the athlete must proceed with extreme caution regarding one’s digestive tract when using this product. For $65 USD, most athletes can go without and not forgo any benefits.

Reasons to buy
  • +

    Potential benefit for cyclists who regularly do high-intensity training

  • +

Reasons to avoid
  • -

    Unpleasant texture and lots of product to consume

  • -

    Expensive for only four doses

  • -

    Can only be used sparingly
