Physical performance side: Molk (Jocko Fuel), creatine (monohydrate, Double Wood Supplements), beta alanine (Double wood)
General health: multi vitamin (whatever is cheap and seems to have a decent ratio), D3 (Jocko fuel), fish oil and krill oil (Viva Naturals, 3rd party verified to have negligent heavy metals and oxidation), iron (whatever is cheap)
Beta Alanine was kind of a surprise to me recently. I just started taking it about a month ago, and have found that in jiu jitsu class, I don't seem to get nearly as tired on the later rolls. I didn't change anything with workouts or diet, just added the beta alanine, so I'm attributing most of that increased endurance to the supplement.
Another note, I found that Double Wood supplements generally seem to have very good prices compared to other brands, and they also have 3rd party purity and accuracy testing done for a lot (if not most) of the things they sell. Most of their stuff is available on Amazon, but when the price is the same I generally try to order from their website.
