Be careful what pills you take
You are partially right. Many vitamin pills come from China and dont have good quality control. Also, its important to take vitamins and minerals that are NOT synthetic and are extracted from either food or plants. That way they are in their complete natural state.
But to say taking vitamin supplements is useless in healthy individuals is wrong. At least in my opinion
