Used about half of the bottle so far, can honestly say they have fought off cramps a few times but other times it seems to not help very much. I run hot so I take double the dosage most days. This is the first anticramp product Ive tried so cant really compare it to other products.
I bought these to try when BTD was out of stock on Sportlegs. The effect - to my judgement - is subtle, but they appear to function as advertised, and they're cheaper than the Sportlegs. I still prefer the Sportlegs, as those capsules seem to do a better job fighting fatigue and helping recovery, but you have to take more, so the cost on a per ride basis is higher.
Endurolytes are an excellent means of maintaining electrolite levels to avoid reduced performance or cramps. I always have some either in my jersey pocket or in my hydration pack during long rides. My wife uses them regularly for restless leg.
I live in an area with very hot, humid summers and often suffer bad post-workout headaches and muscle cramps. I started taking Endurolytes before and after rides, and sometimes before bed on really hot days. I feel noticeably less crummy after hard rides, and the headaches have gone away. If you sweat a lot, I strongly recommend Endurolytes or some other comparable electrolyte supplement.
I am prone to leg cramps after 70 or so miles in the 100 degree plus weather in which we often ride. I now take an Endurolyte at the beginning of a ride and then about one an hour while riding. They keep my cramps away.
I usually complete 3 long rides a week any where from 70 to 80 miles a ride, and then complete some short fast rides (30 miles) on the alternate days. The enduralytes have helped me from cramping (bonking) and I have definitely felt and increase in my performanc4.
In a market full of "snake oil", Endurolytes are the real-deal. They eliminated my cramping problems on longer events and training rides. I also feel much fresh at the end of a long, hot event or ride, when taking Endurolytes...hard to believe, but quite true. I take 1 per hour, and that works for me.
This is one supplement that works as advertised--and not too expensive, either.
I am a triathlete that competes in sprint, Olympic, and Half Ironman Tri's. I just started using the Endurolytes the past few months ad find that they really work. My workouts have improved by leaps and bounds while training in 97 degree Florida heat and Humidity. My heart rate stays much lower by 20 beats and my overall endurance has extended with much less fatigue and pain during my workouts. Well worth giving it a try. My tip... stay ahead of your curve. DO NOT get to your red line. Keep ahead by taking the product BEFORE you get into fatigue meltdown.
