Supplementation is genuinely valuable for a defined set of situations, and the marketing has expanded that set far beyond the evidence.
Genuine needs
Documented deficiency identified by testing - iron, B12, vitamin D, and others. Restricted diets: B12 for anyone avoiding animal foods is essential rather than optional, and iodine, iron, zinc and omega-3 warrant attention. Malabsorption conditions including coeliac disease, Crohn's disease and post-bariatric surgery. Pregnancy and preconception, particularly folic acid. Infancy, for vitamin D and vitamin K. Certain medications that deplete specific nutrients. Limited food access or variety.
Where the case is weaker
A healthy adult eating a varied diet, taking a supplement in the expectation of enhancement rather than deficiency correction. The pattern across nutrition research is consistent: supplementation works reliably when it fills a gap and generally does not when it adds to sufficiency. Large trials of multivitamins, antioxidants and single nutrients in well-nourished populations have repeatedly failed to show the benefits observational research suggested.

See Cognizil PricingA reasonable position
Test before treating where a deficiency is plausible - it costs less than a year of most supplements and gives an answer rather than a guess. Take what your circumstances genuinely indicate. Accept that a low-cost, low-risk supplement taken as insurance is a defensible choice even with small expected benefit. And be honest that the appeal of supplements is that they require no effort, while the interventions with stronger evidence require quite a lot.

- Deficiency correction, restricted diets, malabsorption and pregnancy are the genuine cases
- Supplementation works reliably when filling a gap, not when adding to sufficiency
- Testing costs less than a year of most supplements and gives an actual answer
