At DNAffit, 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 for vitamin D needs:
Polymorphisms of the vitamin D receptor gene and stress fractures
The effect of vitamin D supplementation on the bone mineral density of the femoral neck is associated with the vitamin D receptor genotype
Calcium and vitamin D intake interactions with genetic variants on bone phenotype.
