Lowers the blood sugar levels and taking zinc supplements the sober the HbA1c value?
Study Design:
This overview article contained 14 Rcts with 3978 participants.
Results and conclusions:
The researchers found that taking zinc supplements the fasting blood sugar significantly with 0.19 mmol/L [± 0.08 mmol/L, p = 0.013] reduced. Significant is, there is a link at a 95% reliability.
The researchers found that taking zinc supplements the HbA1c value is not significantly with 0.64% [± 0.36%, p = 0.072] reduced. Not significant because the found p-value of 0.072 was greater than 0.05.
The researchers found that taking zinc supplements had no significant effect on serum insulin levels.
The researchers found that taking zinc supplements the plasma zinc levels in the body significantly with 4.03 μmol/L [± 0.81 μmol/L, p = 0.001] increased.
The researchers found that taking zinc supplements the fasting blood sugar levels in people with diabetes type 1 or 2, with metabolic syndrome or with overweight significantly with 0.49 mmol/L [± 0.11 mmol/L, p = 0.01] reduced. Because the found significant p-value of 0.01 was smaller than 0.05.
The researchers concluded that taking zinc supplements the fasting blood sugar, particularly in people with type 1 or 2 diabetes, overweight or reduced with metabolic syndrome
