There are several supplements that can support energy levels and mental health, including mood and positivity. Here's an overview of some key supplements and their potential benefits:

1. B Vitamins: B vitamins, including B1, B2, B3, B5, B6, B8, B9, and B12, are essential for energy production and neurological function. Deficiencies in these vitamins can lead to mental and physical fatigue[^1].

2. Vitamin C: Known for its antioxidant properties, vitamin C plays a significant role in mood regulation and cognitive function[^1].

3. Iron: Iron is crucial for oxygen transport and energy metabolism, and its deficiency can lead to fatigue and mental burnout[^1].

4. Magnesium and Zinc: Both minerals are involved in numerous biochemical reactions that affect energy levels and cognitive function. Deficiencies may impact mood and energy negatively[^1].

5. Probiotics: These beneficial bacteria can help alleviate symptoms of anxiety and depression by promoting a healthy gut-brain axis[^2].

6. Omega-3 Fatty Acids (PUFA): These are vital for brain health and can reduce symptoms of depression. EPA and DHA, specifically, have shown benefits in reducing depressive symptoms[^3].

7. Vitamin D: Adequate vitamin D levels are linked to better mood and reduced risk of depression[^3].

These supplements can support energy and mental health, but it's crucial to consult with a healthcare professional for personalized advice and to ensure they fit within your overall health regimen.
