A supplement that changed your life?
Has anyone tried a supplement that genuinely changed your life? And I don’t mean “I think I sleep a little better” or “maybe I have slightly more energy.” I’m talking about a drastic difference in your physical or mental health, sleep, energy, aging, etc etc. If yes, what supplement was it, what changed, and how long did it take before you noticed the difference? Also curious whether you had a known deficiency beforehand or whether the result completely surprised you.
