I believe everyone that needs it, should be taking it. I am a very active athletic person. I lift weights and run long distance. I also have a chronic lung disorder. I can definitely recover this product. It has helped in preventing me from getting sick when i was surrounded by people with seasonal flu. I am writing this review after weeks of using it. And one week away from my Two Oceans half race. 🙂 i will definitely be refilling as ibthink i only have about three days worth of seamoss left. 🤭
