Hi neuroo

Welcome to NeuroTalk.

It might be an idea if you saw a qualified dietitian.

A dietitian will be able to review what you eat with you.

Very often, as long as somebody eats in a healthy way and does not have any underlying medical problems, their nutritional needs are met from their diet - a dietitian should be able to advise about this.

As far as possible interactions between the many substances that you taking for their alleged cognitive benefits are concerned, the "Interactions Checker" in this site might help you Drugs.com | Prescription Drug Information, Interactions & Side Effects.

You may find this Abstract of a review of the alleged benefits of claimed cognition-enhancing substances of interest The Changing Drug Culture: Use and Misuse of Cognition-Enhancing Drugs. - PubMed - NCBI.

I take a lot of vitamins and have found them helpful for me for a variety of reasons. Very generally speaking, Ive needed additional help with energy levels probably due to having more than one autoimmune illness
and have had cognitive concerns as one of my rx's has been known to damper down one's cognitive abilities.

The very last item on your list is something I take in a product called "ps 100." I have found it to be very helpful cognitively.

Other things like vitamins D3 and B12 and B6 seem to help me with energy.

Caffeine always helps me with both issues.
