The published research confirms that B12, folate, and B6 deficiencies are clinically relevant and relatively common. PMID 40961307 notes B12 deficiency occurs in approximately 2-3% of U.S. adults with…
“We check your level of B vitamins like homoyine and methylonic acid which measure B12, folate, B6 effectiveness.”
Methylmalonic acid and homocysteine can be tested to measure the effectiveness of B12, folate, and B6, as part of a 'test, don't guess' approach to identifying nutrient deficiencies.
The published research indirectly supports the use of methylmalonic acid (MMA) and homocysteine as functional biomarkers for B12 and folate status. PMID 27916823 (review on B12 among vegetarians) and…
“you want to make sure that you reduce your uh drugs if you can or switch to different drugs or are not that are not depleting the the nutrients or that you actually take the nutrients as a replacement”
If taking nutrient-depleting drugs such as acid blockers, patients should either switch drugs or take the depleted nutrients (including B12) as replacement.
The research provides clear support for the premise that certain medications (notably metformin and proton pump inhibitors/acid blockers) deplete B12 and that deficiency causes clinically significant…
“It inhibits B12 absorption which is critical for so many functions that can cause depression, dementia, neurologic issues. People don't know this”
Long-term use of proton pump inhibitors (PPIs) inhibits B12 absorption, which is critical for many functions, and can cause depression, dementia, and neurologic issues.
The claim that PPIs inhibit B12 absorption is directly supported by PMID 40961307, which explicitly lists PPIs as a risk factor for B12 deficiency alongside other medications. The same review confirms…
“if you taking an acid blocking drug you're going to prevent B12 absorption and even magnesium and and zinc absorption”
Acid-blocking drugs prevent B12 absorption.
The claim that acid-blocking drugs (proton pump inhibitors) prevent B12 absorption is partially supported by the available literature. PMID 40961307 (a review on B12 deficiency) explicitly lists proto…
“vitamin B12 is a pet peeve of mind because our normal range the lab slips might say 220 to 1100 and nobody feels well with a level of 220 so times we've treated people with severe depression that we're told by their PCP they have normal B12”
The conventional lab normal range for B12 (220–1100) is misleading because nobody feels well at a level of 220, and patients with severe depression have been told they have normal B12 when they do not.
The published research supports that B12 deficiency symptoms—including fatigue, depression, and cognitive impairment—can occur across a range of B12 levels, and that current diagnostic thresholds may…

“We check your level of B vitamins like homoyine and methylonic acid which measure B12, folate, B6 effectiveness.”
Measuring methylmalonic acid and homocysteine can assess B12 effectiveness as part of a functional medicine workup.
The provided literature indirectly supports the use of methylmalonic acid (MMA) and homocysteine as functional markers of B12 status. The review on B12 deficiency (PMID: 40961307) notes that standard…
“rather than just taking a drug to suppress stomach acid which we desperately need to digest our food to absorb minerals to absorb B12 to digest protein”
Stomach acid is needed to absorb B12, and drugs that suppress stomach acid interfere with this absorption.
The claim that stomach acid is needed for B12 absorption and that acid-suppressing drugs interfere with this process is a well-established physiological mechanism. PMID 40961307 (a review on B12 defic…
“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 so I basically gave her B12 shots high doses of methyl folate...and she called me back and was doing amazing and all of her symptoms had gone away”
High levels of methylmalonic acid and homocysteine reflect deficient B12 and folate status, and correcting these deficiencies with B12 shots and methylfolate resolved a patient's depression and severe cognitive decline.
The mechanistic claim that elevated methylmalonic acid and homocysteine are biomarkers of B12 and folate deficiency is well-supported by the literature (PMID 40961307, 27916823), and the use of B12 su…
“a B12 shot and they're on a different path”
Giving a B12 shot to patients with low-normal B12 levels who have severe depression can put them on a different (improved) path.

“people might be taking 10 different supplements and they like they say, they all might have selenium in them, correct? And then you're getting toxic doses of selenium 100%. And you don't know that cuz you're not adding it all up.”
Taking multiple supplements that each contain selenium can result in toxic doses of selenium if you are not tracking the total amount across all products.
“there's some other examples like selenium that bru has published and showed there are proteins that have a stronger binding to vitamin K1 that are important for coagulation so these are proteins in the liver um versus for example other proteins that stay in circulation and are activating proteins that are important for calcium signaling and trafficking”
There are selenium-dependent proteins that show differential binding affinity, with some having stronger binding to certain nutrients (like vitamin K1) for acute essential functions such as coagulation, versus other proteins important for calcium signaling.
“people might be taking 10 different supplements and they like they say, they all might have selenium in them, correct? And then you're getting toxic doses of selenium 100%. And you don't know that cuz you're not adding it all up.”
Taking multiple supplements can result in toxic doses of selenium because people don't add up the total selenium content across all their products.
“you need a lot of other minerals and vitamins with magnesium to make them work like B6 vitamin D selenium uh so you need those all to kind of work together as a team”
Selenium is one of several nutrients needed alongside magnesium for them to work properly together.
“you want to talk about a pandemic selenium selenium thyine um um and and you know to to help this this this outer ring deize in in the liver which is where two-thirds of it comes from and the balances in the gut and a little bit in the periphery but the point is that a nutrient deficiency can lead to a hormone deficiency that gets diagnosed as a as organ”
Selenium deficiency may be pandemic and selenium is needed to support the conversion (deiodination) of thyroid hormones, primarily in the liver, which can otherwise lead to a nutrient deficiency being diagnosed as a hormone or organ deficiency.
“if it came down to one or two nutrients D3 and K2 would be up there methyl folate would be right at the absolute top of the chart for me”

“we don't make, for example, one of these postbiotics called urolithin A, so we make it from pomegranate or other ellagitannins that are in, you know, walnuts or berries or whatever.”
Urolithin A is a postbiotic that humans do not make themselves; it is produced by gut microbiome metabolism of ellagitannins found in pomegranate, walnuts, berries, and similar foods.
“these compounds are not acting by themselves. They are actually metabolized by your microbiome. And that's really And the products of that is made by by your microbiome is is called urolithin A.”
Ellagitannins from pomegranate are not acting by themselves; they are metabolized by the gut microbiome, and the product of that metabolism is urolithin A.

“MMP levels were going down and so that's a marker of inflammation that's a marker of inflammation that's also a marker of you know how much collagen you're going to degrade”
In randomized trials using a topical mitochondria-targeting formulation, MMP levels went down, indicating reduced collagen degradation — described as a marker of inflammation and an indicator of how much collagen will be degraded.
“collagen is the protein that keeps your skin together and there are enzymes called matrix metalloproteinases MMPs that degrade collagen that just go shoot up with aging and what top we saw in these trials was that MMP levels were going down and so that's a marker of inflammation that's a marker of inflammation that's also a marker of you know how much collagen you're going to degrade”
Matrix metalloproteinases (MMPs), enzymes that degrade collagen, increase with aging, and MMP levels going down is a marker of reduced inflammation and less collagen degradation.
