Rayaldee is a pre-activated vitamin D prescribed for multiple sclerosis.
"They prescribe that pre-activated vitamin D for multiple sclerosis. It's called Rayaldee." (said at 0:16:56)
Rayaldee is an extended-release formulation of calcifediol (25-hydroxyvitamin D3, a pro-hormone/intermediate metabolite). It is approved and prescribed for the treatment of secondary hyperparathyroidism in adult patients with stage 3 or 4 chronic kidney disease and vitamin D insufficiency, not for multiple sclerosis. Although calcifediol and vitamin D supplementation have been investigated experimentally in multiple sclerosis research trials, Rayaldee is neither indicated nor standardly prescribed for multiple sclerosis.

"While both groups showed an overall trend towards improved cognitive function at the end of the study, the calcifediol group exhibited greater improvements in most cognitive tests. However, the trial had no significant beneficial effects on MS relapse, EDSS score, quality of life, or fatigue in either group, the calcifediol or cholecalciferol."

"This article examines the management of secondary hyperparathyroidism in non-dialysis dependent chronic kidney disease (NDD-CKD) patients in Switzerland, with a focus on optimizing bone and mineral health in CKD stages 3-4... A treatment algorithm incorporating extended-release calcifediol, as well as insights from KDIGO (Kidney Disease: Improving Global Outcomes) for Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD), are presented to refine therapeutic approaches."

Stress and adrenaline trigger the release of histamine.
"And we need to remember adrenaline, stress itself releases histamine, right?" (said at 0:59:30)
The claim states that adrenaline and stress trigger the release of histamine. While psychological and physiological stress can stimulate mast cell degranulation and histamine release via neuropeptides and neuroendocrine pathways (such as corticotropin-releasing hormone and substance P), adrenaline (epinephrine) does the opposite: it is a potent mast cell stabilizer that suppresses and inhibits histamine release via beta-2 adrenergic receptors. Because of this inhibitory action on mast cell mediator release and its physiological counter-effects, adrenaline is used as the first-line medical treatment for acute histamine-mediated allergic reactions and anaphylaxis.

Studies of traditional African tribes show natural vitamin D levels over 150 ng/mL.
"there were studies of tribes in Africa, their natural levels I think are over 150 nanograms per milliliter, right? And naked in the sun." (said at 1:03:00)
Studies measuring serum 25-hydroxyvitamin D concentrations in traditionally living East African populations (such as the Maasai pastoralists and Hadzabe hunter-gatherers) report average levels of approximately 115 nmol/L (~46 ng/mL), with individual values ranging from 58 to 171 nmol/L (~23 to 68 ng/mL). The speaker appears to have confused nmol/L with ng/mL; natural levels are well below 150 ng/mL (which would equal ~375 nmol/L, a level associated with vitamin D toxicity).
