I am a long haul truck driver, 59 yrs old been fighting with diabetes for about 15 yrs. Almost done with diabetes with hard work of other vitamins like turmeric, berberine, drink a lot of water, being on strict protein diet as much as possible being a truck driver last 37 yrs. Let me tell you only using primal for 5 days but can tell you feeling a lot better. No afternoon crashes, bloating is gone, more energy. Haven't felt this good in a long time will reorder.
