Do not make it a false choice

Lifestyle and supplements are not mutually exclusive, but the evidence and role of each differ.

Start with fundamentals

Regular sleep, physical activity, balanced nutrition, social connection and management of medical conditions have broad health relevance beyond any single supplement.

Supplements have narrower evidence

Evidence varies widely by ingredient, population and outcome. NCCIH notes the lack of direct evidence that supplements prevent dementia.

Symptoms deserve assessment

A supplement should not be used to postpone evaluation of persistent memory, attention or neurological changes.
