Vitamin D metabolism and efficacy are dependent on magnesium levels.
"vitamin D is dependent on magnesium. So, so in other words, vitamin D may not work if you don't have enough magnesium." (said at 0:06:05)
No published record matching the exact mechanism and clinical trials verifying the relationship between magnesium levels and vitamin D activation was successfully retrieved during verification; this does not prove the claim false. While biochemical literature generally establishes magnesium as an essential cofactor for the enzymatic conversion and transport of vitamin D (such as hepatic 25-hydroxylation and renal 1α-hydroxylation), specific clinical literature verifying the exact operational claims remains unverified in this check.
The average human attention span is approximately 40 seconds.
"now it's right around 40 seconds. Okay, 40 seconds, not 40 minutes, 40 seconds. So, it's not that's on the average." (said at 0:29:47)
No published record matching the claim that the average human attention span is approximately 40 seconds was located; this does not prove the claim false.
The nephron runs on ketones rather than glucose for its fuel.
"guess what fuel that nephron runs on? It doesn't run on glucose. It runs on ketones." (said at 0:31:54)
No published record matching the claim that the nephron runs on ketones rather than glucose for fuel was located; this does not prove the claim false.
Taking vitamin D before and after travel alleviates jet lag by regulating circadian rhythms.
"Well, when you um have jet lag, one of the best antidotes for that is taking vitamin D before you before you go on the trip. And it really really works. And also taking vitamin D when you get on the other side of where you're flying. So, vitamin D is the antidote to anything related to jet lag. Um because you're actually affecting the circadian rhythms." (said at 1:00:13)
No published record matching the claim that taking vitamin D before and after travel alleviates jet lag by regulating circadian rhythms was located; this does not prove the claim false.
Unverified means no publication matching the claim was located; it does not prove the claim false. Spotted an error? See the corrections policy - disputes from the people quoted are prioritized.
