Of the Table, and of Where the B-Vitamin Family Is Found in Ordinary Food A scholarly essay on dietary sources of thiamine, riboflavin, niacin, pantothenate, pyridoxine, biotin, folate, and cobalamin, with notes on fortification, cooking, and what the plate can and cannot supply It is not unfitting, after speaking of the B vitamins as cofactors and as companions to NAD+, to ask where they sit on the plate. They are water-soluble. They leach into cooking water, fade in light a

Of B Vitamins Taken with NAD+ Precursors: Whether the Family Is Still Needed, and Whether the Combination Harms A scholarly essay from academic literature on combining the B-vitamin family with nicotinamide riboside, nicotinamide mononucleotide, and related NAD+ supplements It is not unfitting to ask whether a person who swallows an NAD+ precursor has thereby paid the household’s B-vitamin bill. Nicotinamide riboside and nicotinamide mononucleotide are themselves forms of vit

Of Vitamin C, and of the Offices It Holds as Cofactor, Antioxidant, and Quiet Regulator of the Genome A scholarly essay drawn from academic research on mechanism, immunity, gene regulation, fatal disease, and the question of dose, including the counsel of Linus Pauling It is not unfitting to consider a simple sugar-acid that the human body cannot make, and without which the sailor once perished of scurvy. Vitamin C—ascorbic acid, or ascorbate at physiological pH—is an essenti

Nicotinamide adenine dinucleotide, written NAD+, is not a vitamin in the popular sense, nor a hormone

Of Vitamin D, and of the Quiet Governance It Exercises over Bone, Blood, and the Common Defence of the Body A scholarly essay drawn from university studies of immunity, bone, genetic regulation, vitamin K2, mortality, sunlight, and the Hawaiian population It is not unfitting, in an age that measures the hidden things of the blood with great precision, to consider a substance long known to sailors and bone-setters, yet only lately understood as a hormone that speaks to the gen

Of Magnesium and the Health of the Living Body We have already spent some time on the health of the mind: attention, the asking of the right questions, and the building of knowledge from what is found. That is well enough. But the mind is not a tenant living rent-free above a vacant house. It is a citizen of a body, and the body has its own laws, which no amount of good intention will repeal. Among those laws is a quiet dependence on magnesium—an element so ordinary that it
