I will give the Doctors Best R-Lipoic a try when I run out of stock in the ALA. I've got enough left probably for a couple of months.

If you have the DNA mutation (called MTHFR polymorphism) that prevents methylation of B12 and folic acid you will absorb in the GI tract but the vitamins will not activate and therefore not lower your homocysteine. This test can be done with blood work. And it doesn't
even need a doctor's order and can be had on the internet.
1000mcg of B12 will be absorbed passively in the GI tract about 1%... about 10mcg. The RDA is 2-4 mcg a day from food.
This was done with a study, and I have it on the B12 thread.
So there are two phases to consider.
The DNA mutation is pretty common. At least 10% and some new info suggesting up to 30% ( a doctor came here a while back from a seminar suggesting the higher figure). I still only post the 10% until I see otherwise.
People with this genetic error develop elevated homocysteine, and hence damage to the blood vessels and heart leading to cardiovascular disease. But also the nerves will suffer because they use the methylated versions only of the B12 and folic acid.
