This is fairly well known.

But generally, these tips are the way to go: https://www.ted.com/talks/sandrine_thuret_you_can_grow_new_b...

Anyways, I personally take:

1. nano encapsulated punicic acid (called Granagard), which crosses the blood brain barrier effectively (search "nano-pso" on Google Scholar)

2. sulforaphane/sulphoraphane (spelling depends on where you are located)

3. co-ultramicronized palmitoylethanolamide + luteolin

4. ubiquinol

5. methylated b vitamins (~50% of the population has a MTHFR variant that generally requires you to need methylated B vitamins, versus regular B vitamins)

6. high doses of gamma linolenic acid (I use evening primrose oil and Jarrow brand is trusted)

7. algae omega 3
