Great product. Helps in preventing & reversing cramps. I use it religiously in combination with salt pills on all my obstacle runs (Spartan Races & Tough Mudder.)
I'm not a fan of the straight melatonin tablets. I always wake up groggy and more tired. These are the first tablets that don't leave me with that feeling of exhaustion the next morning. They work and I hope they don't discontinue it.
