Your antioxidant level is low
Your antioxidant level indicates a diet very low on fresh fruits and vegetables.
You can improve your values by changing your dietary habits. If you experience difficulties to get a higher value, you can possibly make faster progress using high quality food supplements. Nevertheless, you should not rely on them exclusively!
To help your body building up a supply of antioxidants, make sure to get sufficient sleep and try to reduce bad influences, like smoking or stress.
Do not expect any sudden increase in your antioxidant levels. If you are doing things right, you will observe a slow but steady increase.
