Topically applying DMSO to the skin, such as on the foot, penetrates rapidly enough to produce a taste sensation in the mouth within seconds.

"what's wild is you could actually put some on your foot and you literally within seconds you're tasting it. I don't know how that works, but it's a super solvent that will go deep and penetrate into the skin" (said at 0:08:25)

No published record matching the specific claim that topically applying DMSO to the skin (such as on the foot) produces a taste sensation in the mouth within seconds was located; this does not prove the claim false.

Randomized controlled trials show that garlic, hibiscus tea, and nasal breathing can lower blood pressure.

"there's many, many other things that you can do on randomized control trials that can bring down blood pressure: garlic, hibiscus tea, breathing through your nose at night" (said at 0:21:30)

The host's statement bundles three distinct interventions claimed to lower blood pressure in randomized controlled trials (RCTs): 1. Garlic: Supported. Meta-analyses of RCTs demonstrate that garlic supplementation (such as aged garlic) modestly reduces systolic blood pressure (e.g., weighted mean difference of -2.49 mmHg). 2. Hibiscus tea (Hibiscus sabdariffa): Supported. Meta-analyses of RCTs confirm that hibiscus tea significantly lowers both systolic blood pressure (by approximately 4.7 to 7.6 mmHg) and diastolic blood pressure (by 3.5 to 4.1 mmHg). 3. Breathing through your nose at night: Unverified. No published randomized controlled trial evaluating nocturnal nasal breathing or mouth taping for blood pressure reduction was located; this does not prove the claim false. Because the statement bundles these assertions together and no RCT evidence was located for nocturnal nasal breathing, the overall claim is rated unverified.

Consuming a sugary or starchy snack three hours before bed reduces growth hormone secretion by 78%.

"consuming a sugary starch snack three hours before bed uh can shut down your growth hormone by 78%. 98% of respondents say it's true. And 2% say, "Nope, you're just fine." HOST: It's it's true." (said at 0:31:18)

No published record matching the claim that consuming a sugary or starchy snack three hours before bed reduces growth hormone secretion by 78% was located; this does not prove the claim false.

The body experiences a surge of growth hormone that lasts for 90 minutes right upon going to sleep.

"Through the entire day and night, you have this massive spike, 90 minutes of this surge of growth hormone that happens right when you go to bed for 90 minutes." (said at 0:31:50)

No published record matching the claim that the body experiences a 90-minute surge of growth hormone right upon going to sleep was located; this does not prove the claim false.

Adding dietary protein interrupts the process of autophagy during fasting.

"As soon as you start adding protein now we don't get the results of autophagy. Okay? You get other benefits, weight loss, but not autophagy." (said at 0:40:04)

No published record matching the claim that adding dietary protein interrupts the process of autophagy during fasting was located; this does not prove the claim false.

Intermittent and prolonged fasting can resolve eye floaters by clearing out excess protein floating in the eyeball.

"Yes, do more intermittent fasting and prolonged fasting, which will clean up that extra protein that's floating around your eyeball." (said at 0:40:03)

No published record matching the claim that intermittent or prolonged fasting can resolve eye floaters by clearing out excess protein in the eye was located; this does not prove the claim false. Vitreous floaters typically arise from age-related liquefaction of the vitreous humor (syneresis), posterior vitreous detachment, and the aggregation of structural collagen fibrils, for which standard medical management is limited to observation, pars plana vitrectomy, or Nd:YAG laser vitreolysis.

Cold plunging stimulates neurogenesis and the growth of new brain cells.

"It basically it creates some pretty wild stuff in your brain as far as uh growing new brain cells." (said at 0:58:50)

No published record matching the claim that cold plunging stimulates neurogenesis or the growth of new brain cells in humans was located; this does not prove the claim false. Preclinical laboratory research in animal models and cell cultures has examined hypothermia, cold shock proteins (such as RBM3), and cold stress in rodents. For instance, studies have shown that mild hypothermia (35°C) promotes neuronal differentiation of cultured human neural stem cells (PMID: 38523796) and that RBM3 plays a role in neural stem cell differentiation and neuroprotection after brain injury or cold stress in rodents (PMID: 31484925, PMID: 30037926). Additionally, a mouse study found that cold water immersion altered hippocampal brain-derived neurotrophic factor (BDNF) and signaling pathways (PMID: 40752721). However, no clinical studies demonstrate that cold plunging or cold water immersion in humans stimulates adult neurogenesis or grows new brain cells.

TUDCA keeps bile ducts open to prevent bile sludge from backing up into the pancreas and causing pancreatic necrosis.

"TUDCA is a good supplement for pancreatic health. Um, and also TUDCA keeps the the little bile ducts that come from your liver that join the pancreatic duct right before it goes into the small intestine. And sometimes there could be some sludge there. That's why TUDCA comes in there that then would back up um bile into the pancreas itself creating necrosis breakdown." (said at 1:02:44)

No published record matching the claim that TUDCA keeps bile ducts open to prevent bile sludge from backing up into the pancreas and causing pancreatic necrosis was located; this does not prove the claim false. While tauroursodeoxycholic acid (TUDCA) and related hydrophilic bile acids like ursodeoxycholic acid (UDCA) alter bile acid composition and possess choleretic and cytoprotective properties in preclinical and cholestatic settings, there is no clinical or trial evidence demonstrating that TUDCA supplementation prevents biliary sludge reflux into the main pancreatic duct or prevents acute necrotizing pancreatitis.
