Question 78 of 433
Is MTHFR testing useful?

The short answer
No. SKIP. Genetics societies recommend against it.
A large share of the population carries a common variant of this gene. It has been blamed online for everything from fatigue to cancer. The evidence does not support testing or special “methylated” vitamins for people who carry it. I have changed my own mind on this as the data came in.
