I can feel it working
I've used Epsome salts for years as a remedy for sore, tired muscles. I work out 5-7 times a week, min. 60 mins/session and I'm over 40 years old. It seems I'm always sore! :) I tried Flewd (I tried the multi-pack trio) and I swear I could feel the first packet working on my body, more so than regular Epsome salts. My husband tried it also and really felt it worked. That's not to say I had zero soreness after my soak, but I believe I felt better immediately and recovered faster. I have restocked my supply and look forward to my next bath! These smell awesome and I think they work.
