Vitamins

Vitamins research, in depth

Vitamins are essential micronutrients the body cannot synthesize in sufficient amounts. Several act as cofactors that enzymes depend on to function.

Micronutrients with a cofactor role

Vitamins are organic compounds required in small quantities for normal physiology, which the body cannot synthesise in sufficient amounts on its own. Many of the B-group vitamins, in particular, work as enzyme cofactors — Biotin (vitamin B7), for example, is essential to the carboxylase enzymes involved in fatty-acid, glucose and amino-acid metabolism. That cofactor function is precisely why these molecules sit naturally within the Cofactors & Longevity family rather than alongside the experimental peptides elsewhere on the site.

The research collected here treats vitamins as the well-characterised biochemical agents they are. Their roles in metabolism are established science, not open hypotheses.

Where the research stands

Because the underlying biochemistry is settled, the genuine research questions in this area are narrower and more practical: optimal dosing, what deficiency states look like and how they are corrected, the effect of supplementation in specific populations, and absorption. A key distinction runs through all of it — water-soluble vitamins (the B-group, vitamin C) and fat-soluble vitamins (A, D, E, K) behave very differently in how they are absorbed, stored and cleared, and that difference shapes both dosing and safety. It also means "more is better" is simply false here: several vitamins have well-defined upper limits beyond which excess is unhelpful or harmful.

Notable compounds in this category

Biotin (B7) anchors this sub-category as a clear example of a vitamin acting in its enzyme-cofactor role. It connects naturally to NAD+ in the Coenzymes sub-category — NAD+ is itself built from a niacin (vitamin B3) precursor — illustrating how vitamins and coenzymes are parts of one continuous metabolic story.

What to keep in mind

• Vitamin biochemistry is established — the open questions are usually about dose and context.
• Water-soluble and fat-soluble vitamins behave very differently; the distinction matters for dosing and safety.
• More is not better — several vitamins have well-defined upper limits.
• These are essential nutrients the body genuinely requires — the research framing is nutritional, not experimental.
