Hi onemanatatime

Welcome to NeuroTalk - I hope that you find the community as knowledgeable and supportive as I have.

Some thoughts:

I am sceptical about genetic testing (23andme, etc). Having a copy of the apoE4 gene does put you at increased risk of AD and the same applies to whatever else the tests may have showed. However, these are just risk factors - genetic determinism ("OMG, it is in my genes, I am doomed.") is a myth.

The various supplements that you are considering are all produced in your body from the food that you eat. Unless you have an underlying medical problem (your doctor can advise you about this) and unless you are not eating in a healthy way (a dietitian can help here), there is no need to eat those supplements.

All the best.
