When you leave a shaker bottle closed and "empty," the tiny, invisible traces of protein powder, pre-workout, or amino acids (especially supplements containing choline or L-carnitine) remain behind. This creates a dark, damp, airtight environment where anaerobic bacteria (bacteria that thrive without oxygen) multiply rapidly. As these microbes feast on the leftover supplement dregs, they release TMA and volatile sulfur compounds as waste.
