Vitamin B12
The supplement plant-based stacks here treat as non-negotiable
B12 is only reliably available from animal foods or fortification, which is why a vegan or near-vegan diet is the standard case for supplementing it. Deficiency causes fatigue and irreversible nerve damage if left long enough. Older adults absorb it less well regardless of diet. Cheap, safe, and one of the few supplements here with an unambiguous case.
