Being that vitamin C is the dominant antioxidant discovered within the blood and tissues all through the physique, it’s no shock that it’s finest recognized for its highly effective antioxidant capabilities.
Vitamin C: Daily Requirements for Type 2 Diabetes
The beneficial day by day allowance (RDA) for the overall grownup inhabitants is 75 mg for girls and 90 mg for males, with an higher restrict of 2000 mg day by day.

Another overview confirmed vitamin C supplementation decreased random glucose ranges by eight mg/dl (zero.44 mmol/L) and fasting stage by 24 mg/dL (1.36 mmol/L).
While these research do point out that vitamin C supplementation might enhance glucose ranges, one of many points is, all of the trials present contributors with differing quantities of vitamin C, starting from 100 to 1000 mg/day, and for differing durations of time.
Therefore, it’s troublesome to say how a lot is required to decrease glucose and how lengthy it’s worthwhile to take it to see an impact.
Vitamin C as an Antioxidant
Vitamin C is a potent antioxidant. The function of antioxidants within the physique is to neutralize and management free radicals – cells that trigger injury (oxidative stress) and improve the probability of diabetic issues.
Antioxidants might help stop and restore free radical injury brought on by oxidative stress, which in flip improves insulin secretion and glycemic management.
Antioxidants present in entire fruits and greens, together with vitamin C, might help stop diabetes issues.

With this in thoughts, sticking to round 200 mg/ day might be finest follow.
