1.5 years ago my lead level was 9.x, 6 months later it was around 6.x. I just had it tested again 2 weeks ago and it was down to 4.0. Time is one thing that will help lower your lead level. Another thing I have read and done myself is take about 1500 mg of vitamin c daily. I have no scientific proof that vitamin c helps to lower your lead level, but it seems to have helped me to lower mine. BTW I am 67.
