## Questions & Answers

**Q: Does it help with running or just cycling?**
A: I would say that it helps more for cycling, just because cyclists usually work out for longer periods of time. I am a 60 year old mountain biker and if I riding or racing for more than 2 hours, Sportslegs or something to prevent cramps is a must. I get leg cramps and cramps in my hands especially when it is hot and I am sweating. You will be surprised how quickly they work. I keep a baggy with about 10 capsules tucked under my bike shorts. When things go south you can take one every 20 minutes or so.

**Q: Will i lose my gold medal in rio if i take this?**
A: Hello!  Our guess is that if you're participating in the Rio Olympics you've already got a nutritionist telling you what to eat...but for the rest of us these are a good supplement to take.  Thanks!

**Q: What are the active ingredients beside sodium and calcium? Is this the same as an electrolyte pill?**
A: There's no sodium in SportLegs. It's not an electrolyte. SportLegs is 88% premium European natural-source lactate. Taken before exercise, SportLegs raises blood lactate, replicating the natural signal muscles obey later in exercise to curb excess lactate fuel production. Modern imaging research shows excess lactate production is the source of lactic acid. SportLegs is a clever, healthy way to help prevent lactic acid in the first place. Balanced calcium, magnesium and vitamin D are included to speed absorption.

**Q: Why is the single bottle of 120 tablets 3.84 oz and the 3 pack of 120 tables each is only 9.6 oz?  It should be 11.52 oz for 3 bottles.**
A: Poor proofreading.
