Lecithin is worthwhile. The phosphatidylcholine has a lot of online hype and is expensive. Taking lecithin to support normal production of phosphatidylcholine would be more my objective.
Curcumin in a concentrated extract form with black pepper extract (Bioperine) is also good. Most curcumin is low dose because it is unconcentrated turmeric. Vitacost has a good concentrated curcumin in their house brand.

CBD is questionable. It offers a lot of promise but is not a cure-all that many claim. The researched therapeutic dose is quite high, $30 a day or more.

I would love to have an opportunity to try it. It is just so expensive and illegal in Idaho.
