Your using vitamins should not affect the DNA testing.
They will affect the serum blood work results however.
The ranges that labs use were not formulated from people using vitamins, so those ranges are supposed to be "normal" meaning not consuming supplements, but only getting from the diet.
All the results from taking supplements will artificially give higher results, therefore.
