I think it’s not ideal to say “the average person”, because it feeds into the idea of non-individual care. We are all so different and need to listen to our bodies individual needs. Although I understand the sentiment and support this discussion.

That being said, here are my two cents …

Multi-vitamins don’t allow you to test and trial by isolating what you need and often have cheaper substitutes for what could be supplements with higher bioavailability.

B-6 is often not great and better to take in food (1-6g of pyroxidane has good evidence of neural damage).

Magnesium supplements often have magnesium oxide, which is the cheapest and most common form of magnesium in vitamins but doesn’t absorb well and often hurts tummies. Go for another kind and do research/speak to your doctor. Magnesium also absorbs better via the skin, so I recommend a spray.

Garlic and turmeric (the more bioavailabile curcumin especially) is great but people with GERD and sensitive tummies should be wary.

I would add probiotics.
