For addressing brain fog, omega-3 fatty acids have been suggested as potentially beneficial. They are known to help reduce neuroinflammation and oxidative stress, thereby supporting cognitive function¹². Other supplements like multivitamins, zinc, antioxidants, and probiotics have also shown some benefits for cognitive performance³.

Regarding libido enhancement, while the search didn't yield supplements directly from authoritative sources, some general knowledge draws on traditional substances like ginseng and maca root, which have been commonly acknowledged for their potential benefits in supporting libido.

For anxiety, supplements such as ashwagandha have been studied for their effectiveness in reducing stress and anxiety. Studies show that ashwagandha is generally safe for most individuals and can help improve stress scores and cortisol levels⁴. Other supplements that are believed to have calming effects include valerian root, lavender, and chamomile⁵.

For all these supplements, it's crucial to consult with a healthcare provider before starting any new supplement regimen, especially if you are currently on medication or other treatments.
