I disagree with the others insofar as I think the weighty-est things Huberman suggests are very well researched, and he's generally careful to say when research is newer/sparser for certain discoveries but doesn't make a broken-record of himself. For instance: his videos focusing on sleep. When it comes to other optimizations YMMV but aggregate marginal gains would suggest that exploring these may add up. Also these days his video series tends to focus more on interviews with experts in their respective fields, rather than his own prescriptions and perspective. I think that's commendable and great.
