Doctor warns against unnecessary vitamin supplement usage

A doctor warns that vitamin supplements may not be as beneficial as many believe. Fatigue can stem from poor sleep quality or deficiencies in vitamins and minerals, such as iron and vitamin B12. A blood test can help identify specific needs. Personalized vitamin quizzes may oversimplify health issues, leading to unnecessary spending on supplements. The doctor advises caution and suggests focusing on sleep, gut health, and a balanced diet before considering supplements. If supplements are needed, iron, B12, magnesium, fish oil, and zinc may be beneficial, but only if deficiencies are confirmed by a doctor. Supplements should complement a healthy lifestyle, not replace it.
