To improve energy levels and reduce fatigue, several supplements can be considered based on their roles in energy metabolism and cognitive function¹²:

1. Vitamin B Complex: B vitamins (B1, B2, B3, B5, B6, B7, B9, and B12) are essential for converting food into energy. They support metabolism and the production of neurotransmitters, which are crucial for maintaining energy levels³⁴.

2. Vitamin C: This vitamin is important for the synthesis of carnitine, a molecule required for the transport of fatty acids into mitochondria, where they can be oxidized to produce energy³.

3. Iron: Iron is essential for oxygen transport in the blood. Iron deficiency can lead to anemia, characterized by fatigue and weakness⁵.

4. Magnesium: This mineral is involved in over 300 biochemical reactions in the body, including energy production³.

5. Zinc: Zinc plays a role in energy metabolism and the immune system. Its deficiency can result in fatigue³.

6. Coenzyme Q10 (CoQ10): CoQ10 is involved in the production of ATP, the main energy carrier in cells. It has been shown to reduce fatigue levels in various chronic conditions²⁶.

7. Nicotinamide Adenine Dinucleotide (NADH): Similar to CoQ10, NADH is involved in mitochondrial energy production and has been shown to help with chronic fatigue⁶.

8. L-Carnitine: This amino acid is essential for the transport of fatty acids into the mitochondria, increasing energy production¹.
