How do i reduce my a1c?

Need more info: What is your A1c level? If you are diabetic and it is below 7.0 that is generally sufficient. If it is higher than 7 then you need to control your blood sugar better by diet and medication and that needs in-person evaluation by a doctor.

Manage blood glucose: Your physician will guide you here. Don't overlook the opportunity to stay aerobically fit as a key element in your glucose control. You have no ability to change your genetics, but you have complete power to manage your physical fitness. Best wishes.

Get A1C lower.: You can lower your A1C by keeping your blood sugar under good control via proper diet, regular exercise and medications when needed. If your finger sticks can remain in the 90-135 range in the long term, your A1C should drift down quite nicely.
