My child has always had low immunity, and we almost visit the clinic or pharmacy every month. Our home is always stocked with medicine, just in case. Since she started taking R3 Mini, her immunity has noticeably improved, and we’ve had to see the doctor much less often. One morning, I heard her cough so hard that she was gasping, and her voice was very hoarse. I immediately gave her two packets of R3 Mini. By the evening, her hoarse voice had disappeared, and she didn’t cough while sleeping at night. My child is also very happy because she no longer has to see the doctor or take bitter medicine.
