Vitamin D supplementation is most defensible where deficiency risk is meaningful or confirmed, rather than as a universal intervention for every adult.

2. Creatine monohydrate evidence overview
Creatine monohydrate is among the most well-studied supplements for strength and high-intensity exercise performance, with a consistent evidence base when used at established doses.

3. Omega-3 evidence context
Omega-3 benefits depend on baseline diet, dose, and use case; they are not best understood as a universal replacement for good food quality.

4. Magnesium evidence context
Magnesium may be useful in specific contexts, but the evidence does not justify treating it as a cure-all for broad, non-specific complaints.
