i dont think its that right to recommend without knowing your needs and im not a doctor but knowing from some diabetic people around me that you generally need magnesium, zinc and vitamin c at the most.. since as they dissolve in water.. for eyes, vitamin A,C,E and omega 3, copper and zinc again.. for general well being things above works as well but the most B12, iron, zinc what i take some time to time.. like a month taking these supplements and giving a break like for 3-5 months again or less.. thats what i do maybe arguably its wrong or right..
