Multivitamin supplements are general supplements used to make sure that one has the recommended daily intake of vitamins and minerals, in case one's diet is lacking in them. Supplements that are marketed as "Diabetes supplements" are meant for diabetes only. Common supplements marketed as diabetes supplements include: ALA, Chromium, Omega-3s, and antioxidants. Currently, there is no scientific evidence that diabetes supplements are effective. One should never replace their diabetes mediation, such as insulin, with any type of supplement.
