“methylation testing for homocysteine methol acid you know the B vitamins we're talking about like folic acid or the you know vitamin D or Omega-3s and you know zinc I the selenium we list goes on and we see iodine the tremendous amount of deficiencies that exist”
B vitamins are among the nutritional markers assessed during functional medicine evaluation, and deficiencies are widely underdiagnosed in the population.

“found she had a really high level of something called methon acid and homocysteine which are things that most doctors don't check but reflect your status of B12 which is methanic acid and homocysteine which is the folate and even B6”
High levels of methylmalonic acid and homocysteine reflect poor B12 and folate (and even B6) status, which are linked to depression and cognitive decline.
“you look at methylation which is about B vitamins”
Methylation, which depends on B vitamins, is one of the key variables evaluated in a functional medicine approach to Alzheimer's prevention and treatment.

“these minerals and vitamins so you're talking about magnesium zinc calcium B vitamins like these are these are co-actors for these enzymes to make these enzymes run properly and if you have if you don't have you know sufficient levels of those vitamins”
B vitamins act as co-factors for enzymes, and insufficient levels impair proper metabolic and enzymatic function.
“you need all the methylating B vitamins folate B12 B6 um and you need these are all co-actors that basically power all those detox enzymes that are processing all the toxins”
B vitamins (including folate, B12, and B6) are required co-factors for detoxification enzymes that process toxins in the body.

“we fixed his insulin and blood sugar we fixed his gut we fixed his B vitamins we got rid of the Mercury and the guy literally came back like rip and weak from the dead”
Fixing B vitamins, along with addressing insulin, gut issues, and mercury toxicity, was part of a comprehensive treatment that dramatically reversed an Alzheimer's patient's decline.
“I basically gave her B12 shots high doses of methyl folate which is a particular kind saw she had some genes that made her need a special kind of folate and she called me back and was doing amazing and all of her symptoms had gone away”
Hyman gave a patient with MCI B12 shots and high doses of methylfolate (a special form of folate suited to her genetics), which resolved her depression and severe cognitive decline symptoms.
