Best supplements for energy
Ranked the way I'd rank them in clinic: by the strength of the human evidence and how often the shortfall actually shows up. Start at the top. Add the rest only if labs or symptoms say so.
- Iron (only if ferritin is low)
The single most common fixable cause of fatigue in women.
- Vitamin B12 (methyl)
Especially for vegans, people over 50 and anyone on acid blockers.
- Vitamin D3
Low levels track with fatigue and low mood.
- Magnesium glycinate
Cellular energy production and better sleep.
- CoQ10 (ubiquinol)
Mitochondrial energy; essential if you take a statin.
- Rhodiola
Fatigue and stress performance; morning only.
- Creatine monohydrate
Energy at the cellular level; a growing brain story.
