this is a recent post about one poster's experience with the methylation testing.
Most of us keep our B12 over 1000. But 4mg a day is not "too much". You might read higher in testing...but really very little is absorbed from that dose. It is the methylfolate that concerns me about that product.
I take 2 tablets of 5mg methylB12 a week now. Just as insurance.
