The 32 Clinical Elements

32 evidence-reviewed supplement ingredients, each rated for evidence quality and clinical utility.

  1. Vitamin C — Vitamin C supports collagen synthesis, immune defence, and antioxidant protection. Essential for skin, wound healing, and iron absorption.
  2. Vitamin B1 — Thiamine converts carbohydrates into ATP energy, supports nerve signalling, and cardiovascular function. Deficiency is common in heavy-carb and processed-food diets.
  3. Vitamin B2 — Riboflavin forms FAD and FMN coenzymes essential for cellular energy production, antioxidant recycling, and red blood cell formation.
  4. Vitamin B3 — Niacin is a precursor to NAD+, the key coenzyme for energy metabolism, DNA repair, and cellular signalling.
  5. Vitamin B5 — Pantothenic acid synthesises Coenzyme A, enabling fat and carbohydrate metabolism, and supports adrenal hormone production.
  6. Vitamin B6 — Vitamin B6 is required for amino acid metabolism, serotonin and dopamine synthesis, and immune function.
  7. Folate — Folate (as methylfolate) is essential for DNA synthesis, cell division, and homocysteine metabolism. Critical during pregnancy for neural tube development.
  8. Vitamin B12 — Vitamin B12 maintains nerve integrity, enables red blood cell formation, and supports DNA synthesis. Vegans and older adults are at highest deficiency risk.
  9. Vitamin A — Vitamin A is essential for vision, immune defence, skin cell turnover, and gene expression. Best absorbed as preformed retinol.
  10. Vitamin D3 — Vitamin D3 regulates calcium absorption, immune modulation, and mood. Deficiency affects over 1 billion people globally. Most require supplementation in winter months.
  11. Vitamin E — Vitamin E protects cell membranes from lipid peroxidation, supports immune function, and works synergistically with vitamin C and selenium.
  12. Vitamin K2 — Vitamin K2 activates osteocalcin and matrix Gla protein, directing calcium to bones and preventing arterial calcification. Often missing from modern diets.
  13. Magnesium — Magnesium participates in over 300 enzymatic reactions including ATP production, nerve transmission, muscle contraction, and deep sleep regulation.
  14. Calcium — Calcium is the primary mineral for bone density, neuromuscular signalling, and cardiovascular function. Absorption is enhanced by vitamin D3 and K2.
  15. Zinc — Zinc supports immune defence, testosterone production, wound healing, and taste and smell. Deficiency is widespread and affects cognitive and reproductive function.
  16. Iron — Iron enables haemoglobin synthesis and oxygen transport. Deficiency causes fatigue, cognitive impairment, and is the world's most common nutritional deficiency.
  17. Selenium — Selenium activates glutathione peroxidase antioxidant enzymes and converts thyroid hormone T4 to active T3. Essential for thyroid and immune health.
  18. Iodine — Iodine is required for synthesis of thyroid hormones T3 and T4, which regulate metabolism, development, and energy production.
  19. Omega-3 — EPA and DHA reduce systemic inflammation, support brain structure, cardiovascular health, and mood. Most people are chronically deficient without oily fish 3x per week.
  20. CoQ10 — CoQ10 (Ubiquinol) is central to mitochondrial electron transport and ATP production. Levels decline with age and are depleted by statins.
  21. NAD+ — NAD+ is the cellular energy currency that declines 50% by age 50. Precursors (NMN/NR) restore NAD+ levels to support mitochondrial health, DNA repair, and longevity pathways.
  22. Glutathione — Glutathione is the body's master antioxidant and primary detoxification agent. Levels decline with age, stress, and poor diet, leaving cells vulnerable to oxidative damage.
  23. Curcumin — Curcumin inhibits the NF-kB inflammatory pathway, reducing joint inflammation, oxidative stress, and supporting gut and brain health. Requires a bioavailability-enhanced form.
  24. Berberine — Berberine activates AMPK, the metabolic master switch, improving insulin sensitivity, blood glucose, and lipid metabolism comparably to metformin in some studies.
  25. Ashwagandha — KSM-66 ashwagandha reduces cortisol by 20-30% in clinical trials, improves stress resilience, sleep quality, and testosterone in men under chronic stress.
  26. Rhodiola — Rhodiola rosea is an adaptogen that improves mental and physical performance under stress, reduces fatigue, and supports mood and resilience.
  27. L-Theanine — L-Theanine promotes alpha-wave brain activity, creating calm focus without sedation. Often combined with caffeine to smooth stimulation and reduce jitteriness.
  28. Creatine — Creatine is the most evidence-backed performance supplement in existence. Replenishes phosphocreatine for explosive energy, and emerging evidence supports cognitive benefits.
  29. Synbiotics — Synbiotics combine live probiotic strains with prebiotic fibres to improve gut microbiome diversity, immune function, and digestive health.
  30. Tart Cherry — Montmorency tart cherry extract provides melatonin and anthocyanins that improve sleep onset, duration, and quality, and accelerate exercise recovery.
  31. Phosphatidylserine — Phosphatidylserine is the primary phospholipid in neuronal membranes, supporting memory, cognitive processing speed, and healthy cortisol response to stress.
  32. Collagen — Hydrolyzed collagen peptides signal fibroblasts to produce more collagen, improving skin elasticity, hydration, and joint cartilage. Meta-analyses confirm real benefits over 90 days.
