NMN and NR are both good but NMN might not be available anymore as some company decided to repurpose it as a drug instead of supplement. Best combo nowadays looks to be liposomal NR with pterostilbene, a sirtuin activator. NR boosts NAD+ (the main electron transporter in mitochondria), pterostilbene activates sirtuin SIRT1 that regulates aging. B2/Riboflavin might be a good idea as well as it is a FADH donor, secondary electron transport carrier especially in nerves/brain. B1 to the mix as every single metabolic reaction needs it and it's depleted by consuming lots of carbs or drinking alcohol, a common western diet. Niacin is less effective in raising NAD+ but the flush can open up veins and flood hard to reach extremities of the body with blood so it's probably good from time to time. Slow B3 seems to be even worse for raising NAD+.
