What you really need
Supplement Check
Diet, sun, age, sport, goals: which supplements make sense for you, which are optional and which you can skip.
The sorting follows the evidence for healthy people: useful means good evidence for your situation, optional means possible benefit with a control value, unnecessary means no evidence or no need. Doses are usual ranges for adults; with medication and illness your doctor decides. Background in Supplements you do not need.
Not medical advice: the calculator classifies, it does not diagnose.
