Exceeding the gastrointestinal absorption capacity with high oral doses of nutrients like magnesium causes loose stools or diarrhea, serving as an indicator of bowel tolerance.

"you start taking a dosage of a product and you increase it over time sequentially on a day-by-day basis until you get the runs. And the runs is when you break the GI barrier, means that your body cannot absorb any more of this element." (said at 0:10:41)

The physiological mechanism described—titrating oral magnesium until loose stools occur—reflects the well-established principle of intestinal absorption saturation leading to osmotic diarrhea. Intestinal magnesium uptake occurs via active saturable transcellular transport (e.g., via TRPM6 channels) and passive paracellular diffusion. When intake exceeds the gastrointestinal tract's transport capacity, unabsorbed magnesium salts remain in the intestinal lumen. Because magnesium is poorly absorbed in excess, it acts as an osmotic agent, drawing water into the bowel lumen and inducing loose stools or diarrhea. This osmotic effect forms the pharmacological basis of magnesium-based laxatives and the clinical threshold often termed 'bowel tolerance.'

Linus Pauling, Abram Hoffer, and David Hawkins created orthomolecular psychiatry in the 1970s to treat brain dysfunction using high doses of vitamins and minerals.

"a very obscure book that was written in the 1970s by Dr. Linus Pauling, the two-time Nobel Prize winner, Dr. Abram Hoffer, one of the greats in the nutrition industry, and Dr. David Hawkins who is another super genius. And those three gentlemen created what was called orthomolecular psychiatry. And what they were doing is treating advanced states of brain dysfunction with superdosing of nutrients, vitamins and minerals and things like that." (said at 0:10:50)

Linus Pauling coined the term 'orthomolecular psychiatry' in a 1968 paper in Science, building on earlier megavitamin research for schizophrenia conducted by Abram Hoffer and Humphrey Osmond. In 1973, David Hawkins and Linus Pauling co-edited the major volume 'Orthomolecular Psychiatry: Treatment of Schizophrenia' (which included extensive contributions from Hoffer), advocating the use of high doses ('megadoses') of nutrients, vitamins (notably niacin and vitamin C), and minerals to treat severe psychiatric and brain disorders.

  "Megavitamin therapy with niacin (vitamin B 3 , a methyl acceptor) was the proposed remedy (1).When Pauling, using examples from this theory, published his findings in Science in 1968 (2), orthomolecular psychiatry was born.Some mental diseases, he argued, were the result of localized cerebral deficiencies of nutrients, not appreciable in the bloodstream or directly measurable."

Magnesium functions as a vasodilator to increase blood flow.

"Magnesium is a vasodilator, opens up the blood flow and oftentimes migraines are that contraction." (said at 0:38:46)

Magnesium is well-established as a vasodilator that modulates vascular tone and blood flow. It functions by acting as a natural calcium antagonist on vascular smooth muscle cells and by stimulating endothelium-dependent nitric oxide release, resulting in vascular relaxation.

Magnesium is a critical element required for the production of neurotransmitters like serotonin.

"And one of the key elements to produce those neurotransmitters is guess what? Magnesium." (said at 0:41:12)

Magnesium is well-established as an essential micronutrient and cofactor involved in neurotransmitter synthesis and regulation, including the serotonergic pathway. Comprehensive reviews of nutritional influences on the serotonergic system document that magnesium, alongside iron, vitamin D, and B vitamins, serves as an essential cofactor in the synthesis and metabolism of serotonin.
