According to recently done studies, people with type 2 diabetes have an impaired ability to naturally produce nitric oxide.

Having low levels of nitric oxide leads to poor blood vessel health, which can lead to conditions like high blood pressure, kidney disease, and heart disease over time. If you are experiencing such symptoms already, you might have low levels of nitric oxide. 

One study found that when people with type 2 diabetes who took L-arginine, saw their nitric oxide production increased in just one week. (1).

Increasing your nitric oxide levels can also help with increased insulin sensitivity, allowing for better blood sugar control throughout the day.

Another study conducted with 144 people looked at the effects of L-arginine for helping to prevent or delaying the progression of type 2 diabetes. (2)
