Does exactly what it suggests. Struggled with tight calves and cramp, no longer a problem after a week of taking these. Achieved a PB half marathon.
I have been using fuel 5 for many years now. Great taste, gentle on the stomach. Keep you going through hard sessions and race days.
Could never fault any of the brands products , these included.Good taste, texture and nutrient value. Bonus, no nasty tummy issues.
Game Changer - worked a treat racing. Loved the ease of use, didnt have to take a whole bag of hydration in my suitcase.
