About a month ago a friend of mine was telling me that he had a scary experience when he was playing high intensity table tennis one evening. He’s very fit and plays 8-10 hrs a week, but that one time he could no longer hold his racket because he lost the strength in his hand/arm. He’s diabetic and was concerned that it had to do with his sugar levels. I asked him if he drank electrolytes during his matches and he said no, and that he drank mineral water. So he did some looking around and ordered Scrivation XTend powder online because there were a few studies on it and had 5 star reviews. It’s quite expensive but the mix also contains a few BCAA. No sugar. So he tried this and said it was the difference between night and day, and that his muscle recovery was incredible. I asked him to give me a few scoops to try, and I’m wondering if this was the reason I was able to walk 3+ hours last week and 2 weeks ago? Honestly, the day after walking I felt as though I had done nothing, and I was able sit upright for longer periods of time. It could be a coincidence too. Who knows? The powder has just the right ratios of chloride sodium/potassium etc. I'm going to buy a jar and take it regularly to see if this is helpful long term Between menopause night sweats, hot flashes and my weekly power walks I must be losing sodium/potassium and not replenishing it fast enough? I've never had pain with ME so I can't say if it helps with pain, but it does help with muscle recovery as long as I don't go into PEM (which I am able to avoid). I don't think it's a placebo effect but will have to take the powder for a longer period of time. I like that I can sit upright for longer periods of time!
