Review: Bro…. Try it - I was skeptical about this product since the supplement market has been going down the drain and not what they used to be like the good old glorious days in the house of gainz. Let’s face it, supplements are now all talk and not a lot of action. I started running a lot a few months ago along with cardio and body weight exercises trying to get ready for the academy and my legs would feel weak at times and had some low energy as well and would get super sore afterwards. Also I would get some bad chin splints and over all my performance would just suck. I took this product and not only did I feel energized, I performed great on my first run with this product and exercises were amazing. I was like the energizer bunny just going and going and no chin splints either for some odd reason. The next two days, I only felt some minor slight soreness but nothing major and legs were ok as well. I did not feel any jitter and no negative side effects such as nausea, stomach problems, headaches like you would with some pre workout supplements. I did take this product around 8 PM one time and by midnight I couldn’t sleep and was still out exercising in 98 degree weather after deciding to get a second workout lol, (I live in the desert it’s hot out at night). I do recommend taking this product earlier during the afternoon or morning. Once I went to bed, my sleep was very light and couldn’t go into a deep sleep since I took the pills a bit late. It is one pill for every 50 lbs you weight as well. I also had a ghetto sauna suit on (trash bag) and was sweating like crazy but still going. I’m thinking of using this product with my lady as well if you know what I mean, see what’s up 😅🤔 Update: 02/23/24 When I went into the academy on day one, felt like a rite of passage. We got smoked left and right trying to weed out the weak and I took this supplement before going in and I thought I was fit but I was wrong. I want to say this supplement helped me get by getting smoked in 116 degree weather on day one. On the end of the first week, we went through “Black Friday” which is a day where you get smoked left and right for 4 straight hours non stop all the exercises you can think of. One of my mates got a heat stroke and two others were vomiting left and right and another got it worst. I was sweating bullets, there was puddles of sweat on the deck, three toe nails fell out, I was carrying a EMT back pack with medical supplies while running but I kept going. Yes I was exhausted and a lot has to do with mental power and determination in order to get through but I want to give this pills some credit into helping me make it through that day. Don’t take my word for it, try it but always keep in mind that everyone is different and might have a different effect on you. God Bless.
Review: This stuff really works. - This stuff really works. Without it, my legs were on fire 🔥 after 5k race. Some fire 🔥 after 5k training and definitely total burning sensation on the legs, back, neck and arms during half marathon. I'm about 150 male so I take one pill 💊 15 to 30 minutes before training 5k run however distance and the burning 🔥 sensation of lactic acid was gone. At the 5k race events, I take 2 pills. 💊 💊 Very effective with no side effects. I stop eating 12 - 14 hrs before the race and have a handful of combination of walnuts, raisins, pumpkin seeds and almonds with a cup of mushroom coffee as hour and half before race on race day. Then small water based electrolytes pre-race drink of any choice 30 minutes before START time. I floss teeth and rinse mouth with little water as I walk to the starting line. Feeling great the whole time without burning 🔥 sensation and stiffining of muscles after during and after event. And didn't have to stop to stretch all day! I know I should stretch after the run. This is 5k experience. Going to try this out on 1/2 marathon and update my review but... this stuff really works! Why did I wait so long before trying this out? There's no taste. I take no other pills or any supplements on race day until afterwards, just supplements and light meal, preferably at end of day. There's nothing to mix. Just take with water.

## Features

- EXERCISE SHOULDN’T HAVE TO HURT. Most people don’t quit workouts because they’re lazy; they quit because exercise starts to feel uncomfortable too quickly. SportLegs helps your body quickly prepare for activity so effort feels smoother, more controlled, and easier to sustain from start to finish.
- WHY THE HURT CAN SHOW UP FAST. When exercise begins, muscles typically produce lactate fuel faster than they can use it efficiently. This imbalance can contribute to early fatigue, “heavy” limbs, or even “burn” during moderate workouts. It can get better with time, but SportLegs helps accelerate that adaptation.
- FAST-FORWARD WITH SPORTLEGS. SportLegs primes muscles with lactate, their preferred fuel, to encourage a more balanced lactic response during exercise. Many users notice workouts feel different than they expect, with less fatigue, less heaviness, less burn and a fluid, in-the-zone feeling that makes stopping feel optional.
- CHOSEN WHEN IT REALLY MATTERS. From weekend warriors to daily runners, to endurance athletes training for hours at a time, SportLegs has been chosen for decades, from local gyms to Olympic Games. Athletes of all ages turn to it when confidence and consistent performance season after season matter most.
- EASY TO USE, EASY TO STICK WITH. You don’t have to take SportLegs daily for weeks before you feel results. Take it just 30 minutes before activity, 1 capsule per 50 lbs. body weight. US-made with premium vegan lactate, plus calcium, magnesium and Vitamin D. No sodium, bicarb, caffeine, calories, dairy, gluten or GMOs. Fast-forward to workouts you’ll actually want to repeat.

## 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.

### ⭐⭐⭐⭐⭐ Very impressive product
*by A***W on July 26, 2025*

Product works really well. I originally ordered the little sample pack. I used two servings (3 pills each) last week on a 13 mile run, my legs did not feel sore at all. I was able to drive an hour for work afterwards as well. Fast forward to this week, I ran seven miles the other morning without it and my calves were a bit sore after. I just purchased a full bottle because I plan to incorporate this product into my marathon training now.
