NUTRIENT LIBRARY HUB

The Nutrient Library

Intro (2–3 sentences, sets context): Evidence-based guides to the vitamins and minerals most linked to energy, immunity, sleep, and everyday wellbeing — what each one does, the signs of a shortfall, who’s most at risk, and what to actually look for in a supplement. Every page is sourced from NHS, NIH, EFSA, and peer-reviewed research, not marketing claims.

  • Vitamin D The “sunshine vitamin” most UK/EU adults fall short on, especially in winter.
  • Iron Essential for energy and oxygen transport — the most common deficiency in women of reproductive age.
  • Vitamin B12 Critical for energy and nerve function — a near-universal gap for vegans and vegetarians.
  • Magnesium Involved in over 300 processes in the body, from muscle function to sleep quality.
  • Omega-3 Heart, brain, and joint support — most diets fall well short of recommended oily fish intake.
  • Vitamin C An antioxidant your body can’t store or produce — daily intake matters.
  • Zinc Supports immunity, skin, and hormone balance — easy to under-consume on a plant-based diet.
  • CoQ10 A cellular-energy compound that naturally declines with age and with statin use.
