“Most people need lots of supplements to be healthy.”
Strong confidence against a routine need for lots of supplements: large prevention studies do not justify that approach. This does not rule out benefits from a specific supplement for a specific need.
Most well-nourished adults do not need many supplements to be healthy, and routine multivitamin use has not shown broad prevention benefits. Specific supplements can still matter for deficiencies, pregnancy, diet gaps or medical needs.
Safety note: Avoid combining supplements that push nutrient intake above upper limits. Products can interact with medicines and have pregnancy-specific risks.
Talk to a healthcare professional if: Discuss supplements if you take medicines, are pregnant or breastfeeding, or have a medical condition. Products and doses can affect safety.
You do not need a cabinet full of supplements. Choose each one for a clear need, rather than assuming more is healthier.
Review what each supplement is for with your clinician or pharmacist. Keep prescribed supplements until you have discussed any change.
