Type Two Diabetes Lifestyle Change. Are Supplements Needed?

Patient: I am a 31-year-old Filipina mother of two. I had gestational diabetes during both of my pregnancies, and after I gave birth to our second son, I was diagnosed with Type 2 diabetes. We do not have health insurance at the moment, so I’ve been doing my own research and asking nurses we know. Two hours after eating, my sugars were near 300 and my fasting sugar was around 130-145. Through diet and exercise I have been able to lower my blood sugar. Now two hours after eating, my sugar is between 85-115 and my fasting sugar has been under 110. My diet and lifestyle has completely changed. I now eat mainly vegetables, legumes and beans and I juice veggies daily (carrots, radishes, spinach, celery, cucumber, zucchini, green bell pepper, broccoli, and a little lemon). I drink 4-5 8oz bottles of water a day (am trying for more but get too full). Mostly, I have cut sugar and anything deep fried out of my diet as well as processed carbohydrates like breads. I drink 8oz white grapefruit juice a day and 8-12oz raw almond milk throughout the day. I may have a couple ounces of meat a day (chicken, turkey, tuna, salmon, or sardines – no red meat anymore). My question is about my diet. My research has shown that I should probably be taking supplements. I take one multivitamin a day as well as niacin 500mg (I suffer from depression), B12 500mcg, zinc 50mg, and calcium with Vitamin D 1200mg. This is not a “diet” to me and I plan to make this my new way of eating and living. So I need to know if it’s truly healthy. Am I taking too many supplements? Will any of these supplements cause me long-term harm? Is there another supplement that I should be taking?
