At DNAfit, we have a strict inclusion protocol to evaluate whether a gene will be included in our reports. Each gene must have a minimum of 3-peer reviewed studies in humans demonstrating the effect, there must be a consensus on that effect, and that effect must be modifiable through an environmental and lifestyle change.
Below is a sample of our evidence base forvitamin B needs:
Methylenetetrahydrofolate reductase 677C-->T genotype modulates homocysteine responses to a folate-rich diet or a low dose folic acid supplement: a randomised control trial
5,10-methylenetetrahydrofolate reductase genotype determines the plasma homocysteine-lowering effect of supplementation with 5-methyltetrahydrofolate or folic acid in healthy young women
Assessing the association between the methylenetetrahydrofolate reductase (MTHFR) 677C>T polymorphism and blood folate concentrations: a systematic review and meta-analysis of trials and observational studies
