Things worth keeping a reference shelf on, kept apart from the risk categories. Each branch works down from the general to the specific, one entry at a time.

In the news · July 2026 A prospective, non-randomised study at a Mexican hospital followed 171 women with iron deficiency anaemia taking iron daily or every other day. Both schedules improved haemoglobin over three months,…
Half of football injuries are to the lower limb, the risk is concentrated in games and on one play type, and moving a line five yards cut concussions on that play by four-fifths.
Ankles first and knees second, plus two of the best-tested precautions in team sport — a randomised trial of lace-up braces and a warm-up whose benefit depends almost entirely on actually doing it.
Baseball has one of the lowest injury rates in college sport, and one specific arm problem that the rate hides entirely. What the evidence says about volume, fatigue and the two precautions that have been tested.
Calcium per measured tablespoon, why absorption falls as the dose rises, and why 59 trials found a one per cent bone density gain that appears in year one and then stops.
Riboflavin per measured tablespoon, why deficiency almost never occurs alone, and what four hundred milligrams a day did in the migraine trials.
Thiamin per measured tablespoon, the milling step that turned beriberi into an epidemic, and why the Food and Nutrition Board set no upper limit at all.
There is no vitamin D1. There are two forms, the label treats them as interchangeable, and the randomised comparisons put D3 ahead by about 15 nmol/L — with most of the gap in a dosing schedule almost nobody uses.
Vitamin C per measured tablespoon, what a deliberate depletion showed about scurvy, and why the dose-response curve flattens long before the tablet does.
Vitamin D per measured tablespoon, why the food table misses most of the supply, and why three large trials found nothing where a smaller one cut hip fractures by 43 per cent.
